Mechanism of Action:
Reverses hypoxemia.
Reverses hypoxemia.
Indications:
- Confirmed or expected hypoxemia.
- Ischemic chest pain.
- Respiratory insufficiency.
- Prophylactically during air transport.
- Confirmed or suspected carbon monoxide poisoning.
- All other causes of decreased tissue oxygenation.

- Hyperventilation
Adverse reactions:
Decreased level of consciousness and respiratory depression in patients with chronic CO2 retention. Retrolental fibroplasia if given in high concentrations to premature infants (maintain 30-40% O2).
