Oxygen therapy

Oxygen therapy is the administration of oxygen as a medical intervention, which can be for a variety of purposes in both chronic and acute patient care. Oxygen is essential for cell metabolism, and in turn, tissue oxygenation is essential for all normal physiological functions.

High levels of oxygen

High levels of oxygen are given to individuals who have low levels of oxygen in their blood. This can be due to conditions such as chronic obstructive pulmonary disease (COPD), pneumonia, a severe asthma attack, late-stage heart failure, and cystic fibrosis.

Administration

Oxygen can be administered in several ways, including nasal cannula, face mask, and inside a hyperbaric chamber. The method of administration can depend on the patient's condition and preference.

Risks

While oxygen therapy can have many benefits, it can also have risks. These can include dry or bloody nose, tiredness, and in some cases, oxygen toxicity.
