How does hyperbaric oxygen work?
Hyperbaric oxygen therapy is unlike the other methods of oxygen therapy. People will breathe in pure oxygen in a pressurized room or chamber. In the hyperbaric chambers, the air pressure is increased to three or four times the normal air pressure levels. This increases the amount of oxygen delivered to the body’s tissue . This type of oxygen delivery is often used to treat wounds, serious infections, or bubbles of air in your blood vessels. Hyperbaric therapy should be carried out carefully so that blood oxygen levels don’t become too high.

Oxygen is also given to help with the removal of loculated air in the chest, ...
What are the initial needs assessment for oxygen therapy?
The initial needs assessment for oxygen therapy is made clinically, considering what we see when we evaluate the patient, lab findings, and what we know about the underlying disease process. Pay particular attention to three systems when addressing the potential need for oxygen therapy. Typically, we jump to the respiratory system and look for respiratory signs and symptoms, which may include alteration in rate (tachypnea, bradypnea, or apnea) or depth of respiration (hypopnea), difficulty breathing (dyspnea), and changes in color (pallor or cyanosis). However, neurologic signs and symptoms, as well as cardiac response, can provide important clues that will help direct your search for hypoxemia.
