1
Oxygen must be prescribed by a physician, given at the minimum dose to achieve the desired effect, and should never be completely removed from a patient for the purpose of taking a radiograph.
2
Oxygen makes up 21% of the air we breathe, the fraction of inspired oxygen (FiO₂) represents the percentage of oxygen in the measured space, and it is also known as the Carrico index.
3
An adequate oxygen supply is essential to life, brain function ceases after 4 to 5 minutes without oxygen, and it is your responsibility to ensure the room has a full supply of oxygen and delivery methods.
4
To maintain adequate tissue oxygenation while minimizing cardiopulmonary work, with the lungs supplying oxygen and removing carbon dioxide from the body.
5
Hypoxemia refers to inadequate oxygen levels in arterial blood to meet physiological needs, with oxygen and carbon dioxide carried to and from body systems in the blood, and small amounts of oxygen chemically bound to hemoglobin.
6
21% of oxygen is required to maintain homeostasis, the amount of oxygen in blood or air is expressed as a percentage of the volume or as oxygen tension/partial pressure written as PO₂, and carbon dioxide is written as PCO₂.
7
Carbon dioxide enters red blood cells, diffuses into the plasma of systemic capillary blood, and is removed from the body with the help of hemoglobin.
8
Excessive CO₂ increases blood acidity or alkalinity by changing the pH, and bicarbonate (HCO₃) helps prevent acidity.
9
Pulmonary function refers to the lung’s ability to exchange oxygen and carbon dioxide efficiently, and it is measured by arterial blood gases, including concentrations of O₂, CO₂, HCO₃, acidity, and SaO₂.
10
Hypoxemia is defined as an inadequate level of oxygen in the arterial blood to meet physiological needs; Hypercapnea occurs when carbon dioxide remains in the arterial blood; Inadequate oxygenation of the blood is when PaO₂ is below 60 mmHg, and hemoglobin saturation is less than 90%.
11
⚫️Pulse oximetry monitors oxygen saturation in hemoglobin, is a fast, noninvasive method, with normal SaO₂ values ranging from 95-100%, ⚫️while values less than 85% indicate tissues are not receiving adequate oxygen.
12
The pulse oximeter measures oxygen and pulse rate by converting light intensity data, and the probe can be placed on the finger, toe, earlobe, temple, nose, or forehead.
13
Oxygen is delivered under pressure and is humidified by passing through distilled water to prevent drying of the respiratory membrane.
14
-Oxygen delivery is measured in liters per minute. -Complex systems provide a controlled amount of premixed room air and oxygen, -simpler systems deliver a prescribed amount mixed with room air, with concentration varying based on the rate of respiration.
15
Oxygen is piped into rooms, recovery areas, and radiology through a wall unit, supplied from a central source at 60-80 pounds per square inch, and regulated by a flow meter attached to each wall outlet.
16
Portable oxygen tanks are compressed to 2000 lbs/in² and have two regulatory valves: one controls pressure and indicates the oxygen level and the other measures the rate of oxygen flow.
