Here are the key steps for emergency treatment of hypothermia after cardiopulmonary resuscitation:
1. Remove any wet clothing and dress the person in dry clothing or wrap them in blankets to retain body heat.
2. Gradually warm the core body temperature, prioritizing warming of the head, neck and chest areas using your own body heat.
3. Administer warm fluids by mouth if possible, otherwise intravenously. Do not provide food or alcohol.
4. Continuously monitor breathing, pulse and body temperature. Provide additional CPR if needed.
5. Evacuate to a medical facility without delay for further assessment and treatment once the person is stabilized.

Obstructions are classified as mild if the victim can cough but has wheezing, or severe if the victim cannot speak, breathe, or cough. The Heimlich maneuver is recommended to relieve severe obstructions.
This document provides an algorithm for basic life support (BLS) healthcare providers to follow when responding to an adult cardiac arrest for a patient with suspected or confirmed COVID-19. The algorithm outlines the steps to take including checking for breathing and pulse, activating emergency response, retrieving an automated external defibrillator (AED) and emergency equipment while donning personal protective equipment, and beginning cycles of chest compressions and ventilations or continuous chest compressions with passive oxygen depending on the patient's condition and AED analysis.
Choking occurs when something blocks the flow of air into the lungs, preventing breathing. If someone is choking, remain calm and ask if they can speak or breathe. If not, call for help and perform abdominal thrusts by standing behind them and thrusting inward and upward into their abdomen until the object is dislodged or they can breathe on their own. If they become unconscious, tilt their head back, lift the chin, and give two breaths before checking breathing and continuing abdominal thrusts or a finger sweep if still blocked.

Precautions like monitoring weather, wearing appropriate attire, and adjusting activity levels can help reduce risks to personal safety during exercise.
This document provides information about exercising in cold conditions and discusses hypothermia. It covers topics like how the body generates and loses heat, factors that influence heat loss, signs and symptoms of hypothermia, and treatment approaches for mild, moderate, and severe hypothermia. Guidelines are provided for exercising safely in cold weather, such as dressing in layers, keeping extremities warm, and monitoring for signs of cold stress. The effects of cold on exercise performance are outlined, noting that activities like swimming are higher risk due to increased heat loss through water conduction and convection.
Heat stroke occurs when the body's temperature regulation system fails and body temperature rises to dangerous levels. It represents a failure of the body's ability to maintain thermoregulatory homeostasis. Symptoms include headache, nausea, confusion and loss of consciousness. Treatment involves rapid cooling of the body, typically using evaporative cooling techniques, to lower the core temperature and prevent irreversible organ damage. Aggressive rehydration and treatment of complications such as seizures, arrhythmias or hypotension are also important for management. Rapid cooling is crucial to improving outcomes in heat stroke patients.
The document discusses mechanisms of body temperature regulation and abnormalities of thermal regulation. It explains that the hypothalamus helps maintain a constant core temperature between 36-37°C despite changes in heat production and the environment. Temperature is regulated through vasodilation, sweating, shivering and other mechanisms in response to heat and cold exposure. Prolonged heat or cold exposure can cause the body to adapt through increased sweating or non-shivering thermogenesis. Abnormalities include heat stroke from excessive heat, hypothermia from cold exposure, and fever caused by pyrogens raising the temperature.
Vital signs are key physiological measurements that include body temperature, pulse, respiration, and blood pressure. They provide basic information about the functioning of major organ systems and can help detect medical issues. Normal ranges vary with age, but body temperature typically ranges from 36-37°C, pulse from 60-100 beats/minute, respiration from 12-20 breaths/minute, and blood pressure from 90/60 mmHg to 140/90 mmHg for adults. Abnormal vital signs can indicate conditions like fever, infection, shock, or hypotension and should be monitored closely.
Environmental emergencies include
COLD-INDUCED INJURIES
Heat-induced injuries
altitude pulmonary edema

Stages of death can be classified into immediate, early, and late changes. Immediate changes include irreversible cessation of brain function, respiration, and circulation. Early changes involve loss of skin elasticity and pallor, muscle relaxation, and eye changes. Late changes include algor mortis (body cooling), livor mortis (postmortem lividity), rigor mortis (muscle stiffening), and eventual decomposition through autolysis and putrefaction. Understanding these postmortem changes can help estimate time of death and determine cause.
Exposure to extreme heat or cold can cause hyperthermia or hypothermia in the human body. Hyperthermia refers to high body temperature from heat exposure and can cause heat exhaustion or heat stroke. Hypothermia is low body temperature from cold exposure and can lead to frostbite. Symptoms of hyperthermia include dizziness, nausea, and rapid breathing. Symptoms of hypothermia include shivering, impaired movement, and confusion. Management techniques for hyperthermia involve moving to a cool place, loosening clothing, and giving cool fluids. For hypothermia, techniques include preventing further cooling, replacing wet clothes, and gradually rewarming with blankets or body heat.
This document summarizes first aid procedures for heat exhaustion, heatstroke, hypothermia, and frostbite. It outlines signs and symptoms of each condition and provides guidance on first aid management. For heat illnesses like heat exhaustion and heatstroke, first aid includes removing the person from heat, cooling their body, and providing fluids. For hypothermia, treatment ranges from removing wet clothing and adding dry layers for mild cases to calling emergency services and performing CPR if needed for severe cases. Frostbite treatment involves gently warming affected areas and seeking medical help.
Cold Related Injuries. Hypothermia, Frostbite & Trench footEneutron
This document discusses various cold-related injuries including hypothermia, frostbite, and trench foot. It defines these conditions and describes risk factors, stages or classifications, signs and symptoms, and treatment approaches. Hypothermia occurs when the body loses heat faster than it can produce it, causing a dangerous drop in core body temperature. Frostbite causes skin and tissue damage from freezing, with severity classified into degrees. Trench foot results from prolonged exposure of wet or damp feet to cold conditions. Proper treatment depends on injury severity but prioritizes rewarming and seeking medical help.
The body maintains a core temperature of 37°C through balancing heat production and heat loss. The hypothalamus acts as the body's thermostat to regulate temperature. Exercise in hot or cold environments can disrupt the body's ability to maintain this temperature balance. Proper hydration is important to avoid heat-related illnesses when exercising in hot conditions. Dehydration of more than 1% body weight can increase core temperature and cause complications.
The document provides information on thermoregulation and illnesses related to heat and cold exposure. It discusses the normal mechanisms of heat loss and gain and how they are affected by hot and cold environments. Various minor and major heat-related illnesses like heat rash, heat exhaustion and heat stroke are described. The risks, signs, symptoms and management of these conditions are outlined. Cold-related injuries like frostbite and hypothermia are also summarized, including treatments like gradual rewarming. Investigations for hypothermia and approaches for mild versus severe hypothermia are highlighted.
This document provides information on assessing and interpreting vital signs, including temperature, pulse, respiration, blood pressure, and pain.

Vital signs are usually taken on admission, with changes in condition, before/after certain medications or procedures, and according to hospital policy in order to monitor a patient's health status and detect any deviations from normal ranges.
This document discusses hypothermia, including what it is, the causes, symptoms, and treatment. Hypothermia occurs when the body's core temperature drops below 35°C and can be caused by prolonged exposure to cold temperatures. Symptoms include shivering, confusion, slow speech and movement, and loss of feeling in extremities. To treat hypothermia, remove the person from cold, insulate them with blankets, add gentle heat like warm drinks or a lukewarm bath, and never give alcohol which can lower body temperature further.
Are you looking for a long-lasting solution to your missing tooth?
Dental implants are the most common type of method for replacing the missing tooth. Unlike dentures or bridges, implants are surgically placed in the jawbone. In layman’s terms, a dental implant is similar to the natural root of the tooth. It offers a stable foundation for the artificial tooth giving it the look, feel, and function similar to the natural tooth.

Osvaldo Bernardo Muchanga
Gastrointestinal Infections
GASTROINTESTINAL INFECTIONS result from the ingestion of pathogens that cause infections at the level of this tract, generally being transmitted by food, water and hands contaminated by microorganisms such as E. coli, Salmonella, Shigella, Vibrio cholerae, Campylobacter, Staphylococcus, Rotavirus among others that are generally contained in feces, thus configuring a FECAL-ORAL type of transmission.
Among the factors that lead to the occurrence of gastrointestinal infections are the hygienic and sanitary deficiencies that characterize our markets and other places where raw or cooked food is sold, poor environmental sanitation in communities, deficiencies in water treatment (or in the process of its plumbing), risky hygienic-sanitary habits (not washing hands after major and/or minor needs), among others.
These are generally consequences (signs and symptoms) resulting from gastrointestinal infections: diarrhea, vomiting, fever and malaise, among others.
The treatment consists of replacing lost liquids and electrolytes (drinking drinking water and other recommended liquids, including consumption of juicy fruits such as papayas, apples, pears, among others that contain water in their composition).
To prevent this, it is necessary to promote health education, improve the hygienic-sanitary conditions of markets and communities in general as a way of promoting, preserving and prolonging PUBLIC HEALTH.
Gastritis and Gastric Health
Gastric Health is one of the most relevant concerns in human health, with gastrointestinal infections being among the main illnesses that affect humans.
Among gastric problems, we have GASTRITIS AND GASTRIC ULCERS as the main public health problems. Gastritis and gastric ulcers normally result from inflammation and corrosion of the walls of the stomach (gastric mucosa) and are generally associated (caused) by the bacterium Helicobacter pylor, which, according to the literature, this bacterium settles on these walls (of the stomach) and starts to release urease that ends up altering the normal pH of the stomach (acid), which leads to inflammation and corrosion of the mucous membranes and consequent gastritis or ulcers, respectively.
In addition to bacterial infections, gastritis and gastric ulcers are associated with several factors, with emphasis on prolonged fasting, chemical substances including drugs, alcohol, foods with strong seasonings including chilli, which ends up causing inflammation of the stomach walls and/or corrosion. of the same, resulting in the appearance of wounds and consequent gastritis or ulcers, respectively.
Among patients with gastritis and/or ulcers, one of the dilemmas is associated with the foods to consume in order to minimize the sensation of pain and discomfort.

Controlling Hypothermia
at Sea
2. 1 2
All seafarers face various risks during operations of a seagoing
vessel. For example, you may get caught up in a mooring line
(net) and sustain an injury. You may also fall into the ocean while
performing your duties on deck and suffer from hypothermia as a
result of the ensuing decrease in your body temperature.
Among these risks, hypothermia can be especially perilous.
Even without falling into the ocean, you may begin to develop
symptoms simply during your normal duties, and not even
realize it. By that time, it may be too late. You may consider the
symptoms of hypothermia to be exhaustion or generally just
feeling unwell, and you may overlook them.
This may be your first time hearing the word "hypothermia", but it is
actually a very serious condition with a mortality rate of 20% - 90%.
The SOLAS Convention, the International Convention for the
Safety of Life at Sea, also stipulates that seafarers must be
sufficiently educated regarding hypothermia.
It is, therefore, extremely important to foster a wide
understanding among seafarers and everyone else involved in
maritime matters concerning exactly what hypothermia is and
what can be done in order to prevent it.
That is why these guidelines have been created. We hope that
they will prove useful.

Q
A
What is Hypothermia?
Hypothermia occurs when your body
temperature falls below 35℃ . It is an
extremely dangerous condition with a
mortality rate of 20% - 90%!
Further Details
"Body temperature" as used above refers to what is known as "core
temperature". Core temperature refers to such things as rectal temperature,
bladder temperature, esophageal temperature and pulmonary artery
temperature, but it is generally taken as rectal temperature (to be precise, a
measurement taken at a depth of about 7cm from the anus).
It is not possible to measure body temperature correctly in regard to
hypothermia by using the same methods as when taking your temperature
normally, such as under the armpit or under the tongue. A true measurement
of core body temperature can be taken, be it rectal, bladder or esophageal.
The easiest and so most commonly used method to gain such a reading is a
rectal measurement.
There are two types of hypothermia.
Accidental Hypothermia
Secondary Hypothermia
Caused by accidents or unforeseen
circumstances
Caused as a secondary result of illness,
drugs, poor health or other factors
These guidelines focus on "accidental hypothermia," which all seafarers
must be aware of in the course of performing their duties.

Q
A
What causes hypothermia?
Hypothermia is caused by exposure to a
cold environment!
Further Details
The surface of the human body, in particular the skin, is layered with nerves
that detect temperature, which maintains the normal body temperature
within a fixed range of approximately 36 - 37 ℃. If this range is deviated from,
that information is transmitted to the body temperature center of the
hypothalamus in the center of the brain and measures such as contraction
or expansion of blood vessels are used in order to adjust body temperature
accordingly.
However, exposure to an excessively cold environment means that these
adjustments can no longer be performed.

Q
A
How is hypothermia classified?
Hypothermia can be divided into three
types: mild, moderate, and severe.
Further Details
Q
A
What kind of symptoms appear with
hypothermia?
The representative symptom of mild
hypothermia is "shivering". As hypothermia
progresses the symptoms change and
become severer.
Further Details
The following is an explanation of the changes that occur within the
body depending on the type of hypothermia.
Hypothermia is generally classified as follows in accordance with body
temperature.
35 - 32℃
32 - 28℃
Lower than 28℃
Mild hypothermia
Moderate hypothermia
Severe hypothermia
The mortality rate increases as the body temperature falls.
• When body temperature starts to fall, first the body
temperature center and peripheral mechanisms
come into operation, attempting to return body
temperature to above 36℃ through the action
of sympathetic nerves, causing vasoconstriction,
tachycardia, shivering, cold extremities,
hyperventilation and excessive urination.

Chapter 1 Hypothermia Chapter 1 Hypothermia
As seen above, hypothermia mainly appears with symptoms relating to the
nervous system, respiratory system and skeletal muscle, all of which should
be relatively easy to observe. Symptoms relating to the blood and metabolic
systems are harder to notice.
Taking all of these points into account, observe those around you from the
perspective of their potentially suffering from hypothermia.
You should also use your own body as a basis for making judgements.
• Mainly suppresses function of the central
nervous system, reducing cogitative capabilities
and impairing judgment.
• Also makes feelings slow and sluggish.
• Shivering becomes apparent.
• Extreme suppression of the central nervous
system impairs consciousness and can lead to
coma.
• Heartbeat goes into arrhythmia and cardiac
output slows.
• Suppression of breathing means that oxygen
and carbon dioxide cannot be exchanged, and
oxygen levels in the blood fall.
• Functions of organs other than the nervous
system, heart and lungs are also affected.
• Functioning of the digestive system is also
reduced, causing intestinal obstruction, and
muscles become rigid and unable to move.
• Impediments to the blood and metabolic
systems suppress the action of organs such as
the liver, kidneys and pancreas.
• Coma, respiratory failure, heart failure and low
blood pressure can all occur in a short period of
time.
• Although each case is different, there is still
a chance of recovery. Resuscitation should be
performed immediately.
• Breathing stops.
• Immediate heart failure.

Q
A
Can the individual physical conditions of
each seafarers also make a difference?
Yes, the individual physical conditions
of each seafarers can make a difference.
Please take all due care.
Further Details
When fatigue from work and lifestyle accumulates, seafarers may feel
exhausted, suffer from pneumonia, influenza or other illness, or go for
long periods with insufficient sleep, they are more prone to developing
hypothermia; hence, extra caution is required.
Failure to eat after drinking alcohol also reduces the body's capacity to
generate heat and makes a person more likely to develop hypothermia.
Sufferers of diabetes, chronic cardiopulmonary disease or endocrine disease
are also more likely to develop hypothermia, so caution should be paid
accordingly.
Q
A
Under what kind of circumstances can
seafarers suffer from hypothermia?
Potential causes of hypothermia for the
crew of a seagoing vessel include falling
into the ocean, being adrift in the ocean,
working in a cold environment on deck,
and working inside onboard cold storage.
Further Details
The primary cause of hypothermia symptoms is a decrease in external
temperature. In an environment with an external temperature below 10 -
15℃ , it can become difficult for the human body to maintain the regular body
temperature of 36 - 37℃ .
However, even within the permissible range of external temperature, the risk
of hypothermia can still increase as a result of extended exposure, clothing
conditions, nutritional conditions, the presence of chronic disease and other
factors .

Q
A
What is the first thing to do if a seafarers
falls into the ocean?
The most important thing is to get them out
of the water as quickly as possible!
If they have stopped breathing, perform
artificial respiration.
Further Details
The longer a person is left exposed in the sea, the lower their chances of
survival. The mortality rate climbs very high if they are not pulled quickly out
of the cold seawater.
If the victim has drowned, securing respiratory function must be the first
step. Start by administering cardiopulmonary resuscitation while blowing five
times into the mouth of the victim, (while two times is the generally accepted
practice, in the case of respiratory failure due to drowning, five times is more
suitable in order to clear the airway obstruction).
If the drowning victim's heart has stopped, perform heart massage at a rate
of 100 - 120 times per minute. If you have an AED, then you may use that.
(However, if body temperature is low, in the 32 - 35℃ degree range, you may

Chapter 3 Saving and Treating Hypothermia Victims
Chapter 3 Saving and Treating Hypothermia Victims
Q
A
What can be done in order to quickly
identify seafarers who have developed
hypothermia for reasons other than falling
into the ocean?
The early identification of hypothermia
requires noticing for yourself and
"identification through observation by a
third party".
Further Details
Apart from actually falling into the ocean, seafarers are at risk of hypothermia
due to such factors as "being adrift in the ocean," "working in a cold
environment on deck" and "working inside onboard cold storage." As
hypothermia proceeds gradually under these circumstances, it is more than
possible for individuals themselves and those around them to not notice it's
advance.
For example, even if you experience feelings such as "I'm kind of cold and my
body feels sluggish," "I can't concentrate" and "I just don't have any energy"
you still may not suspect hypothermia, allowing it to proceed into more
serious symptoms.
If the people around you also notice that "something about you is different,"
they need to ask if you have been in a situation placing you at risk of
hypothermia, observe you closely, and make a suitable judgment. This can
lead to rescue before it is too late.
Key points for noticing in yourself and by others are such things as an
"exhausted expression," "sluggish movements," "dulled emotions," "impaired
judgement," "slow response to questions" and "cold body".
In particular, you should maintain a firm understanding of the changes in
symptoms due to body temperature as outlined earlier in these guidelines.
* Is speech slower than normal?
* Is a response slow or delayed?

3-3 Emergency Treatment for Hypothermia After Cardiopulmonary Resuscitation (Heat Retention / Warming)
Chapter 3 Saving and Treating Hypothermia Victims
Chapter 3 Saving and Treating Hypothermia Victims
Q
A
What kind of emergency treatment
should be provided after cardiopulmonary
resuscitation?
The basics of emergency treatment are
"change out of wet clothing," "carry to a
warm place" and "raise body temperature."
Further Details
Whether hypothermia is caused by falling into the ocean or other factors, the
best method for recovery is to "warm the body." In order to achieve this, first
the victim needs to be placed in a warm environment (heat retention).
After achieving that, you will need to immediately begin increasing the body
temperature of the victim (warming).
During this step you should increase the temperature at a rate of 0.5 - 2℃
per hour, rather than all at once. This is because a rapid increase in body
temperature can also induce shock.
Furthermore, while the order presented here is "heat retention first, followed
by warming," these steps should actually be performed almost simultaneously.
If the victim is in a condition that allows eating or drinking, food and drink
are also effective to raise temperature.
• Immediately change wet clothes into dry clothing.
• Move the victim to a heated room at 21 - 25℃ and warm using blankets and
warm clothing.
• If you don't have items like blankets at hand, use anything and everything
that can shut out the cold, including newspapers, cardboard, vinyl and
sleeping bags.
• It is advisable to offer warm and easy to eat food and drink such as warm
sugar broth or soup. Chocolate and other sweet foods are also effective
(glucose and carbohydrates are good because they are absorbed quickly,
while protein and fats are bad because they are absorbed slowly).
• Alcohol, coffee and tea promote the production of urine. This can lead to
dehydration, so they should not be provided in excess.
• Do not allow the victim to smoke.
• Do not offer food and drink if the victim is unconscious.
• Use heating materials such as hot water bottles and thermal patches to heat
just the trunk of the victim's body (stomach, chest, back, around the neck).
• Avoid heating the victim's extremities. Heating the extremities will cause
cold blood from the hands and feet to circulate into the heart, suddenly
lowering core temperature and causing cardiac shock (rewarming shock).
• For the same reason, there is no need to massage the victim's hands and feet.
• When applying heat, be careful of low temperature burns.
• The victim can also be placed in a bath of warm water (40 - 45℃ ), but
unless you have access to facilities for monitoring body temperature, this
approach is not recommended.

Q
Q
A
A
Once a person has recovered consciousness
from hypothermia, should he/she be
allowed to move around?
What is the next step after emergency
treatment?
In the period immediately
after the victim has regained
consciousness, suddenly moving
the person's muscles will cause
cold blood to flow into the heart
and lead to arrhythmia or shock,
so massaging them or having
them move around is prohibited.
In principle, you should consult a specialist
(doctor).
Further Details
If emergency treatment does not seem to have had a full effect, continue
to perform as many measures as possible while seeking radio medical
consultation or requesting maritime rescue from the closest land-based
medical facility.
• Even if the symptoms appear to have improved, be mindful of the following points.
• The symptoms of hypothermia can recede, and the victim can appear to
be healthy again, but internal changes still happening inside organs can
cause sudden change in condition.
• Blood irregularities, arrhythmia, changes in blood pressure and changes in
the respiratory functions of the lungs can all lead to death, meaning that
observation (overall expression and responses when talked to) is required
until the victim can be taken to a doctor.
• The victim's vital signs (consciousness level, state of breathing and
breathing frequency, pulse and rectal temperature) should be observed,
and state of urination, etc. be recorded for reference.
It is very difficult to tell the difference between apparent death and actual
death in hypothermia victims. Even if the victim has been in cardiorespiratory
failure for a comparatively long period of time there are still cases in which
brain death is yet to occur and resuscitation is possible. It is therefore vital
to keep conducting emergency lifesaving procedures without giving up until
a specialist is consulted. Do not stop cardiopulmonary resuscitation or
observation until the victim's body temperature
is back to 32 - 35℃ .
Keep conducting emergency lifesaving
procedures without giving up until a
doctor confirms death.
Also continue observation.
* However, once body temperature has
returned to 32 - 35℃ and stabilizes, it is fine for
the person to move around.
Do not let the person walk
around or do exercise!

● Thorough preparation of clothing to prevent the cold
When working in low temperatures, a full range of clothing should be
prepared, including thermal underwear, gloves, hats and cold resistant
clothing.
The use of disposable thermal patches is also effective.
● Not working for many hours in low temperatures
Change assigned duties frequently, keeping work times in low
temperatures as short periods as possible.
● Maintenance of temperature inside the vessel
Maintain a suitable temperature inside the vessel, in working areas,
cabins, etc.
● Provision of sufficient nutritional intake from meals
While maintaining health by eating sufficient meals, avoid damaging health
and lowering stamina due to excessive drinking or eating.
● Relieve exhaustion through sufficient rest
Avoid the accumulation of exhaustion due to long working hours or
insufficient sleep.
● Full understanding of hypothermia
Having a full understanding of hypothermia allows you to realize and avoid
the potential risks, or to notice and halt symptoms before they become
too far advanced. This knowledge can also lead to prevention and early
discovery of hypothermia in the people around you.
Q
A
What can we do in order to prevent
hypothermia?
The basics of hypothermia prevention are to
have a thorough knowledge of the causes
and symptoms of hypothermia and to
thoroughly protect against the cold.
Paying due attention to the working
environment of seafarers and their physical
health can also aid in prevention.
Further Details
The following points can help to prevent hypothermia.

Clothing is ultimately the best way to prevent hypothermia.
In principle, you can take reference from the kind of protective clothing used
in mountain climbing in cold seasons.
These kinds of clothing include the following.
Protective Clothing
• Cold resistant clothing (top)
• Heat-retaining shirt, sweater, etc. (more effective if worn in multiple layers)
• Cold resistant, waterproof trousers
• Heat-retaining underwear for both upper and lower body (more effective if
worn in multiple layers)
• Heat-retaining socks (more effective if worn in multiple layers)
• Cold resistant hat (including one that can be worn as a hood covering the
entire head, mask type, etc.)
• Cold resistant gloves
• Use of heat-retaining scarves is also effective
In addition to the above articles of clothing, cold resistant shoes are also
effective.
Items Other Than Clothing
• It is also effective to put items that will help to keep you warm, such as
disposable thermal patches, inside your clothing.
• If adrift in a lifeboat, etc. after an accident at sea, wearing an immersion
suit or heat insulation device (insulation sheet) equipped to the lifeboat is
also effective.
• Carrying around a thermos flask containing a hot drink and drinking from it
while at work as required is also effective.

• Body temperature can fall 25 times faster in water than in air.
• Factors such as water temperature, body size, volume of fat and movement
in the water all influence survival.
• Moving your body in the water greatly accelerates decline of body
temperature. Unless there is someone nearby trying to save you, do not
move around.
• Heat is lost rapidly from the head, so try to keep it out of the water as
much as possible.
• The more of your body you can keep out of the water, the less volume of
heat will be lost and the higher your chances of survival.
• Using the HELP position (as shown above) to keep your arms and legs close
to you and, if there are other people nearby, wrapping your arms around
each other's shoulders, will increase your chances of survival.

We have tried to describe hypothermia in the simplest possible
terms.
Occurrence of hypothermia is not only limited to seafarers
on vessels sailing through arctic waters. It can easily occur in
environments, both natural and artificial, that are simply a bit
cold.
It is, therefore, important for all seafarers and those affiliated
with shipping companies to remain aware of how hypothermia
can affect them.
We hope these guidelines will prove useful as a point of
reference.
We wish you all safe voyages and good health in you work.
