Heat related disorders abstract
Heat related pathologies are a group of disorders, associated with impairments of thermoregulation, which occur while individuals are exposed to high temperatures. The spectrum of these clinical entities ranges from syndromes with mild/moderate clinical manifestations, like heat edema/cramps/rash to the life-threatening heat stroke.
Heatstroke updates
Heatstroke is a life-threatening condition caused by an inability to regulate body temperature, leading to hyperthermia. There are two types: classic, caused by environmental heat exposure without adequate cooling; and exertional, caused by strenuous physical activity overwhelming the body's ability to dissipate heat. Heatstroke causes central nervous system dysfunction, multi-organ failure, and temperatures over 40.5°C. Treatment involves rapid cooling and supportive care, while prevention focuses on avoiding overexertion in hot conditions, staying cool, and protecting vulnerable groups.

Clinical management of heat related illness, moh
Heat-related illnesses range from mild to life-threatening. Heat stroke is the most severe form and occurs when the core body temperature rises above 40.5°C. It can cause damage to the central nervous system and other organs. Immediate cooling through methods like ice packs and cold water is critical for survival, as mortality from heat stroke can be as high as 70% without prompt treatment. Factors like extreme heat, strenuous physical activity, age, and medical conditions increase the risk of developing heat stroke.
Hyperthermia
Hyperthermia is an elevated body temperature due to failed thermoregulation where the body produces or absorbs more heat than it can dissipate. When body temperatures become too high, it is a medical emergency requiring immediate treatment. The most common causes are heat stroke from prolonged heat exposure and adverse drug reactions. Treatment involves cooling measures like rest in shade, drinking water, and even immersion in cool water or medical cooling for severe cases. Prevention focuses on limiting heat exposure, staying hydrated, and using personal cooling systems for those at high risk.
Hypothermia
Hypothermia is a condition where the body's core temperature drops below 35.0°C, impairing normal metabolism and functions. Symptoms depend on temperature, ranging from shivering and confusion in mild cases to paradoxical undressing and increased risk of heart stopping in severe cases. Treatment involves warm drinks and clothing for mild hypothermia, minimizing movement and using heating blankets and warmed fluids for moderate cases, and potentially ECMO or cardiopulmonary bypass for severe hypothermia. Complications can include arrhythmias, hypotension, thrombosis, pneumonia, organ damage, and eventually cardiac or respiratory failure and death if not treated.
Heat illnesses in children
This document discusses heat-related illnesses including heat stroke. It begins by defining heat stroke as a failure of the body's thermoregulatory mechanism during periods of high heat that results in a dangerously high core body temperature above 41°C. Heat stroke demands urgent attention due to its high mortality rate and risk of permanent neurological damage. The document then discusses the body's normal temperature regulation mechanisms and how factors like increased heat production, decreased heat dissipation, and reduced behavioral responses can lead to heat stroke. It describes the signs and symptoms of different heat-related illnesses on a continuum from minor to most severe, heat stroke. Risk factors, types, causes, diagnosis and features of heat stroke are also summarized.
Heat Related Illness and Injuries
Heat-related illnesses and injuries are the most frequent cause of environmentally related death in the United States, resulting in over 400 deaths annually. Risk factors include dehydration from a lack of water consumption, obesity, and certain medications. Minor heat injuries include heat rash and heat cramps. Moderate heat injury is heat exhaustion, while major heat injury is the life-threatening heat stroke with a core temperature over 104°F. Prevention focuses on proper hydration, limiting outdoor activity during peak heat hours, and recognizing symptoms to promptly treat potential illnesses or injuries.

This document defines various types of heat injury including heat edema, heat rash, sunburn, heat tetany, heat syncope, heat cramps, heat exhaustion, and heat stroke. It identifies factors that influence heat injury such as acclimatization, physical fitness level, fatigue, food and alcohol consumption, and medications. Prevention of heat injuries requires monitoring the wet bulb globe temperature index and ensuring soldiers are properly acclimatized, hydrated, and rested.
Heat related illnesses
Heat-related illnesses range from mild conditions like heat syncope to life-threatening heatstroke. The body normally cools itself through sweating and other mechanisms, but high humidity or dehydration can interfere with cooling. Heatstroke occurs when thermoregulation fails and the core body temperature exceeds 40.5°C. Symptoms include confusion, seizures, and organ damage. Treatment involves rapid cooling through cold fluids, ice packs, and fans before complications develop. Proper hydration and acclimatization can prevent exertional heat illnesses.
Heat Stroke
Heat stroke occurs when the body is unable to regulate its temperature, leading to high core temperatures that can cause direct tissue damage and acute renal failure. There are two main types - classic heat stroke which occurs after prolonged heat exposure in vulnerable individuals like the elderly or chronically ill, and exertional heat stroke which occurs rapidly in unacclimated people exercising in hot environments. Symptoms include a core temperature over 40°C and changes in mental status. Treatment involves rapid cooling through ice application and cold water gastric lavage to reduce the core temperature to 39°C within 30 minutes, followed by monitoring for complications like rhabdomyolysis or organ damage.

Heat related injuries
Extreme heat can cause heat-related illnesses and death if the body is unable to cool itself. Heat exhaustion occurs when the body's cooling mechanisms fail, causing symptoms like clammy skin, dizziness, and nausea. Heat stroke is the most severe form and is a medical emergency, with symptoms like confusion, lack of sweating, and body temperature over 105 degrees. To prevent heat illness, spend time in air conditioning, drink fluids, and monitor for symptoms in yourself and others during periods of high heat.
Hyperthermia and hypothermia
Hyperthermia occurs when body temperature rises above normal levels, with symptoms including shivering, clumsiness, slurred speech, confusion, and fatigue. If not addressed, cells will die and ultimately result in death. To cope, the body cools internal organs and one should drink water. Hypothermia is when body temperature falls below average, with symptoms like shivering, dizziness, hunger, faster breathing, trouble speaking, and slight confusion. To treat, move the person somewhere warm, remove wet clothing, wrap them in blankets protecting head and torso first.
Thermoregulation of Body
Thermoregulation is a process that allows your body to maintain its core internal temperature. All thermoregulation mechanisms are designed to return your body to homeostasis. This is a state of equilibrium. A healthy internal body temperature falls within a narrow window.

The Health Effect of Heat-Illness on Baseball and Softball Umpires
The Health Effect of Heat-Illness on Baseball and Softball UmpiresThe Windsdor Consulting Group, Inc.
Baseball and softball umpires are affected by heat-related illness like other professionals who work in the outdoor environment. Many officials are volunteers while other receives compensation for their efforts. Regardless of the level of officiating from Little League to the Major Leagues, most are affected by heat-related illness in the summertime. Although heat-related illness is discussed in general by some colleges and high schools in their programs, the umpiring associations engaging these officials has failed to recognize the hazard and risks. In order to provide awareness of heat-related illness and how it affects an umpire’s performance on the field, a presentation was created to train officials to understand what happens when they fail to hydrate, rest, and take the necessary precautions that can affect their health. Heat exhaustion is the primary cause for umpires to make poor judgments for calling balls and strikes as well as making critical decisions on rotating into position to make calls on plays. Many lower level officials will take assignments for doubleheaders or multiple game assignments in the summer without regard for their ability to meet expectations. By creating awareness, we hope to improve the lives of baseball and softball officials and improve their performance on the field by understanding the effects of heat-related illness.Hypothermia
Hypothermia, also known as hypotheralmia, is a condition where the body's internal temperature drops below normal, typically defined as 95°F or 35°C. It is caused by prolonged exposure to cold temperatures and can be life-threatening if not properly treated. The document discusses the history, epidemiology, classification, symptoms, pathophysiology, risk factors, treatment, and prevention of hypothermia. Key points include that hypothermia can occur even above freezing temperatures, symptoms range from shivering to loss of consciousness depending on severity, and treatment involves slowly rewarming the body while avoiding rough movements.

Heat and cold injuries
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.
Heat stroke
Heat stroke is a severe heat-related illness that occurs when the body becomes unable to regulate its core temperature, causing it to rise rapidly. There are two main types - exertional heat stroke, which affects young active individuals, and classic nonexertional heat stroke, which more commonly affects elderly or ill people. Heat stroke is life-threatening and can cause damage to organs and death if not promptly treated. Factors that contribute to heat stroke include increased heat production from physical exertion or medical conditions, reduced ability to dissipate heat through sweating or blood flow, and an inability to acclimate to hot environments.
Environmental injuries
Drowning occurs when liquid enters the lungs and prevents oxygen absorption, leading to hypoxia, acidosis, and death. Near-drowning refers to survival over 24 hours after submersion. Drowning causes over 8,000 deaths per year in the US, with 20-25% in children. Diagnosis involves assessing for hypoxia, vomiting, and mental status changes. Treatment focuses on rescue breathing, airway management, and oxygen supplementation.
Heat Stroke.pptx
Heat stroke is a life-threatening condition that occurs when the body becomes unable to regulate its core temperature, causing it to rise rapidly. Left untreated, it can cause damage to the brain, organs and other body systems. The main symptoms include a core body temperature above 104°F, altered mental state, and hot, dry skin. First aid involves rapidly cooling the body through methods like cold water immersion or ice packs while seeking immediate medical help, as rapid cooling is key to preventing complications. Risk factors include high heat and humidity, dehydration, strenuous physical activity, and age. Proper prevention focuses on staying hydrated, limiting time outdoors in extreme heat, and wearing loose-fitting, light clothing.
Thermoregulation and ageing
Thermoregulation, or the maintenance of core body temperature, is compromised with age due to several physiological changes. Older adults have less efficient vasoconstriction and decreased cardiac output, muscle mass, and peripheral circulation. They also have delayed and diminished shivering responses. These thermoregulatory changes increase risks for hypothermia in cold environments and hyperthermia in hot conditions. Nurses should be aware of risk factors and implement plans to promote healthy thermoregulation and comfort for older patients.
Fever - disturbance in general systemic state
This document discusses abnormal body temperatures including fever, hyperthermia, and hypothermia. It provides details on the causes, pathogenesis, clinical findings, and treatment of fever. Key points include: Fever is defined as a rise in core body temperature above normal limits independent of ambient conditions, often caused by infection, immune reaction, or tissue damage. Pathogenesis involves exogenous pyrogens stimulating cells to produce endogenous pyrogens like interleukin-1 and -6 that raise the hypothalamic temperature set point. Fever progresses through increment, fastigium, and decrement stages. Treatment involves antimicrobials, antipyretics, and anti-inflammatories.

Vital Signs.pdf
This document provides information on assessing various vital signs, including temperature, pulse, respiration, and blood pressure. It discusses normal ranges for adults, factors that can affect readings, techniques for taking measurements, and purposes of assessment. Key topics covered include how the body regulates temperature, sites for taking pulse and assessing circulation, types of breathing and factors influencing respiration rate and depth, and the meaning of systolic and diastolic blood pressure measurements.
Mechanisms of skin temperature regulation
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.

Hypothermia
The drawbacks of climate change are so overt. The Disturbance of Great Ocean Conveyor currents led to the extreme changes in temperature around the globe in the form of a cooler northern, warmer tropical and cooler snowy winter, warmer summer. Many deaths from hypothermia were reported especially in refugee camps as it is not well equipped. Hypothermia is a medical emergency that occurs when the body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C). Hypothermia occurs as the body temperature falls below 95 F (35 C). When body temperature drops, heart, nervous system and other organs can't work normally. Left untreated, hypothermia can eventually lead to complete failure of heart and respiratory system and eventually to death.
Metabolism and thermoregulation
The document discusses human thermoregulation and metabolism. It describes how the hypothalamus controls thermoregulation through peripheral thermoreceptors to maintain core body temperature within a narrow range. It outlines the mechanisms used to increase or decrease body temperature, such as vasoconstriction/vasodilation, shivering, and sweating. Disorders like hypothermia and hyperthermia are also examined, along with their causes, symptoms, and treatment approaches.
Climatic disorders
This document discusses various health impacts of climate change including direct effects like heat stroke from extreme heat and injuries from floods/storms, and indirect effects through changes in infectious diseases and food availability. It then provides details on heat-related illnesses like heat rash, heat cramps, heat exhaustion, and heat stroke, describing symptoms, risk factors, and treatments. Similar details are given for cold-related issues like hypothermia, frostbite, and how to respond to help victims. Throughout, it emphasizes staying hydrated, seeking cooling environments, and urgent medical care when needed.
termoreglarea.ppt
This document summarizes key concepts related to thermoregulation, fever, hyperthermia, and hypothermia. It describes the body's mechanisms for heat production and heat loss during thermoregulation. Fever is defined as a regulated increase in body temperature due to infectious or non-infectious pyrogens and the immune response. Hyperthermia occurs when the body fails to properly regulate temperature due to external or internal factors. Hypothermia develops when heat production is insufficient to maintain normal body temperature. The stages, physiological effects, treatment approaches, and potential uses of induced hypothermia are discussed for each condition.

CAPNOGRAPHY and CAPNOMETRY/ ETCO2 .pptx
End-tidal carbon dioxide (ETCO2) is the level of carbon dioxide that is released at the end of an exhaled breath. ETCO2 levels reflect the adequacy with which carbon dioxide (CO2) is carried in the blood back to the lungs and exhaled.
Non-invasive methods for ETCO2 measurement include capnometry and capnography. Capnometry provides a numerical value for ETCO2. In contrast, capnography delivers a more comprehensive measurement that is displayed in both graphical (waveform) and numerical form.
Sidestream devices can monitor both intubated and non-intubated patients, while mainstream devices are most often limited to intubated patients.

Pneumothorax and role of Physiotherapy in it.
This particular slides consist of- what is Pneumothorax,what are it's causes and it's effect on body, risk factors, symptoms,complications, diagnosis and role of physiotherapy in it.
This slide is very helpful for physiotherapy students and also for other medical and healthcare students.
Here is a summary of Pneumothorax:
Pneumothorax, also known as a collapsed lung, is a condition that occurs when air leaks into the space between the lung and chest wall. This air buildup puts pressure on the lung, preventing it from expanding fully when you breathe. A pneumothorax can cause a complete or partial collapse of the lung.

Hypotension and role of physiotherapy in it
This particular slides consist of- what is hypotension,what are it's causes and it's effect on body, risk factors, symptoms,complications, diagnosis and role of physiotherapy in it.
This slide is very helpful for physiotherapy students and also for other medical and healthcare students.
Here is the summary of hypotension:
Hypotension, or low blood pressure, is when the pressure of blood circulating in the body is lower than normal or expected. It's only a problem if it negatively impacts the body and causes symptoms. Normal blood pressure is usually between 90/60 mmHg and 120/80 mmHg, but pressures below 90/60 are generally considered hypotensive.

- 4. Epidemiology Predominantly in children and elderly Male >Female EHS- 4.5/100,000 person’s affected per FB season ~600 deaths/year in the USA
- 5. Exercise Associated Muscle Cramps (Heat Cramps) • painful involuntary muscle contractions/spasms occurring in the setting of strenuous exercise and hot temperatures
- 6. Heat Exhaustion • Athlete has obvious difficulty continuing with exercise • Core body temperature is usually 101 to 104ºF at the time of collapse • No significant dysfunction of the central nervous system (seizure, altered consciousness, persistent delirium) is present
- 7. Heat Exhaustion Symptoms • Tachycardia and hypotension • Extreme weakness • Dehydration and electrolyte losses • Ataxia and coordination problems, syncope, light- headedness • Profuse sweating, pallor, "prickly heat" sensations • Headache • Abdominal cramps, nausea, vomiting, diarrhea • Persistent muscle cramps
- 8. Heat Injury • Exertional heat illness with evidence of both hyperthermia and end organ damage, but without any significant neurologic manifestations. • Collapse during strenuous activity, a core temperature above 104 to 105°F, and the absence of neurologic findings.
- 9. Exertional Heat Stroke • Multisystem illness characterized by central nervous system (CNS) dysfunction (encephalopathy) and additional organ and tissue damage (eg, acute kidney injury, liver injury, rhabdomyolysis). • Core temp > 104F
- 10. EHS- Symptoms • Disorientation • Headache • Irrational behavior • Irritability • Emotional instability • Confusion • Altered consciousness • Coma • Seizure
- 11. Severe Non-Exertional Hyperthermia (Classic Heat Stoke) • Most often patients over 70, with underlying chronic medical conditions that impair thermoregulation, prevent removal from a hot environment, or interfere with access to hydration or attempts at cooling
- 12. Thermoregulation Evaporation-occurs when water vaporizes from the skin and respiratory tract. Most effective mechanism. Conduction-direct heat transfer to an adjacent, cooler object. Convection-transfer of heat to a gas or liquid moving over the body. Heat transfer occurs when the gas or liquid is colder than the body. Radiation-is the emission of electromagnetic heat waves
