Oxygen therapy is the use of oxygen as medical intervention to maintain enough oxygen
in conditions such as hypoxia, hypoxemia, and other related conditions. Oxygen may
be administered through a nasal cannula, face mask, or through hyperbaric oxygen chamber.
This therapy helps maintain oxygen level in the blood for treatment of acute and chronic
diseases such as chronic obstructive diseases (COPD), pneumonia, and asthma. Long-term
therapy with oxygen is often useful in people suffering from COPD. Certain other acute
or chronic disease conditions where oxygen therapy is effective include cystic fibrosis,
dysplasia, heart failure, sleep apnea, and lung disorders
