Oxygen therapy

In oxygen therapy, oxygen is delivered by mask, nasal prongs, nasal catheter, or transtracheal catheter to prevent or reverse hypoxemia and reduce the work of breathing. Possible causes of hypoxemia include emphysema, pneumonia, Guillain-Barré syndrome, heart failure, and myocardial infarction (MI).

Oxygen therapy prevents or reverses hypoxemia and reduces the work of breathing. Thank you!
