The document discusses oxygen therapy, including its definition, purpose, delivery methods, nursing considerations, and complications. Oxygen therapy delivers oxygen at concentrations greater than 21% to treat hypoxemia. Delivery methods include nasal cannula, face masks, venturi masks, and tracheostomy collars. Nurses must carefully monitor patients and devices to ensure safe and effective oxygen delivery while avoiding complications like toxicity. Oxygen therapy should be gradually decreased and stopped once a patient's condition has stabilized.

Oxygen therapy is a treatment that delivers oxygen gas for you to breathe. Overview. You can receive oxygen therapy from tubes resting in your nose, a face mask, or a tube placed in your trachea, or windpipe.
Oxygen Cylinders and Flowmeter- Uses and Maintenanceshashi sinha
Oxygen cylinders contain oxygen under pressure, and the pressure gauge gradually falls as the cylinder is depleted. A full-size E cylinder (the size fitted to most anaesthetic machines) contains approximately 680 l of gas. Manufacturers label the cylinders to confirm this. The medical gas flowmeter is a medical device for oxygen or medical air inhalation of first-aid and hypoxic patients in the hospital, including oxygen flowmeter, and medical air flowmeter. Oxygen flowmeter is mainly used to regulate the flow of oxygen, oxygen humidification.
Oxygen therapy is a treatment that provides you with supplemental, or extra, oxygen. It can help you feel better and stay active. Oxygen is a gas that is vital to human life. It is one of the gases that is found in the air we breathe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

5. Oxygen
Definition
• Oxygen is a colorless, odorless, tasteless gas
that is essential for the body to function
properly and survive.
6. Oxygen therapy
• Oxygen therapy is the administration of
oxygen at a concentration of pressure greater
than that found in the environmental
atmosphere (i.e. 21%) to treat or prevent
hypoxia.
• Oxygen therapy is a key treatment in
respiratory care.
7. Purpose
• The main purpose is to increase oxygen
saturation in tissues where the saturation
levels are too low due to illness or injury.
8. Three clinical goals of oxygen
therapy
• Treat hypoxemia.
• Decrease work of breathing (WOB).
• Decrease myocardial work.
9. Indication of O2 therapy
• Documented hypoxemia
• An acute care situation in which hypoxemia is
suspected.
• Severe trauma
• Acute myocardial infraction
• Short term therapy(eg. Post anaesthesia recovery)
• Increased metabolic demands, i.e burns, multiple
injuries and severe infection.
10. Indication contd….
• Severe respiratory distress( acute asthma or
pneumonia)
• Chronic Obstructive pulmonary disease ( COPD
including chronic bronchitis, emphysema and chronic
asthma)
• Pulmonary hypertension
• Anaemia
• After severe haemorrage
• Poisoning with chemical that alter the tissues ability
to utilize O2 e.g carbon monoxide poisoning.
11. Assessment of need
Need is determined by measurement of
inadequate oxygen tensions or saturations, by
invasive or non-invasive methods, or the
presence of clinical indicators.
• Arterial blood gases
• Pulse oximetry
• Clinical presentation
15. Administration of Oxygen therapy
Nasal cannula or prongs
• It is disposable plastic device with two protruding
prongs for insertion into the nostrils, connected to an
oxygen source and used for low-medium
concentrations of oxygen (Fio2 ranges from 24-44%
of O2 at 1-6 liter of O2.
• A flow rate of 0-6 L/minute can be used with nasal
cannula depending upon the requirement of oxygen

• Epistaxis
• At flow rate of more than 6 L/minute does not
help in improving oxygenation and of no use.
• Above a flow rate of 4 L/min (without
humidification) there is increased chance of
nasal irritation.
19. Face mask
Face masks that cover the client’s nose and
mouth which is used for oxygen inhalation. Exhalation
ports on the sides of the mask allow exhaled carbon
dioxide to escape. A variety of oxygen masks are:
1. Simple face mask:
2. Partial rebreather mask
3. Non rebreather mask
4. Venturi mask
5. Face tent
20. Contd….
1. Simple face mask:
• A simple face mask is made of clear , flexible ,
plastic or rubber that can be molded to fit the
face.
• There is no reservoir bag.
• The simple face mask delivers oxygen
concentrations from 40% to 60% at liter flows of
5-8 L/min, respectively.
21. Contd…
• Flow rates and percent oxygenation values are as
follows:
5L/min= 40%

2)Partial Rebreather Mask
• The mask have a reservoir bag must remaine inflated during
both inspiration and expiration.
• It has one two-way valve connecting the mask and the
reservoir bag
• The two-way valve allows about one-third of exhaled air to
get into the bag.
• O2 concemtration: 70-80%
• Flow rate: 6-15 L/min
25. Contd…..
• The oxygen flow rate must be maintained at a
minimum of 6 L/min to ensure that the patient
does not rebreathe large amounts of exhaled
air.
• The remaining exhaled air exits through vents.
28. Contd….
3)Non Rebreather Mask:
• This mask provides the highest concentration
of oxygen (60%-100%)at a flow rate 6-
15L/min
• It is similar to the partial rebreather mask
except two one –way valve prevent
conservation of exhaled air.
• The bag is an oxygen reservoir so only
oxygen flows from the bag to the mask.

5)A face tent:
• A face tent is used as an alternative to aerosol
mask especially to patient who report
claustrophopic on wearing an aerosol mask.
• A face tent delivers oxygen concentration of
28-100% with flow rate from 8-12L/min.
39. Contd…
Tracheostomy collar:
• It is a small mask that fits over the patient’s
tracheostomy site.
• The mask has an exhalation port which
remains patent at all times and a port that
connects to the oxygen source with a large
bore tubing.
• The flow rate is usually set at 10L/min.
40. Contd…
T-piece
• A T-piece is a T-shaped device which connects
oxygen source to artificial airway (endo-
tracheal tube or tracheostomy). Flow rate 8-10
L/min (deliver 60-100 %).
• Used to deliver oxygen therapy to an
intubated patient who does not require
mechanical ventilation.
43. Key nursing consideration
• Oxygen must be administered with care.
• Since oxygen acts as a drug, it must be prescribed
and administered in specific dose in order to avoid
oxygen toxicity. The dosage of oxygen is started in
terms of concentration and rate of flow.
• Oxygen therapy should be given continuously and
should not be stopped abruptly until the patient has
recovered.
44. Contd….
• Sudden discontinuation can wash-out body stores of
oxygen resulting in fall of alveolar oxygen tension.
• Change the nasal catheters at least 8 hours or more
often.
• When oxygen therapy is discontinued, it should be
done gradually.
45. Contd…
• Watch the patient receiving oxygen therapy
continuously to detect the early signs of oxygen
toxicity.
• Promote safety measures; inform that smoking is not
permitted in the area of oxygen use.
• Place “NO SMOKING” signs in patient’s room or
door.
46. Contd…
• Oxygen cylinder should be stored at a low
temperature because high temperature can cause
expansion of the gas with consequent loss of gas
through safety valve.
• Never increase or decrease the flow of oxygen
when the nasal cannula is in the patient’s nostrils.
• Do not use electrical appliances close to oxygen.
47. Contd…
• Oil or grease should not be used on the regulator
and cylinder because in the presence of high
concentration oil is likely to catch fire and the
cylinder may explode.
• Have fire extinguisher available.
• Ensure the humidifier bottle is always at least 1/3 full
with sterile water.
48. When to stop Oxygen therapy
• Weaning should be considered when the patient
becomes comfortable, underlying diseases is
stabilized, BP, pulse rate , skin color, respiratory
rate are within normal range.
• Weaning can be gradually attempted by lowering
its concentration or discontinuing oxygen for a
fixed time .eg : 30 min and re-evaluating the
clinical parameters and Spo2 periodically.
49. Contd…
• Patients with chronic respiratory diseases
may required oxygen at lower concentration
for prolong period.
