    • Rapidly diffuses across alveolar walls
    • Binds to hemoglobin in RBC
    • Reverses effects of hypoxemia in brain, heart, other body tissues
    • Increases arterial oxygen tension
    • Necessary for breakdown of glucose into ATP
  2. Indications and field use of Oxygen:
    Systemic or local hypoxemia is present

    Dyspnea, respiratory arrest, chest pain, shock, cardiopulmonary arrest, unconsciousness, submersion, toxic inhallations, stroke, head injury, seizures, critical patient
  3. Contraindications of Oxygen:
    None in prehospital
  4. Adverse reactions of Oxygen:
    None in prehospital

    High pressure is reduced with a regulator
  12. Special Notes on Oxygen:
    COPD - may experience respiratory depression with high flow because their systems are regulated with hypoxic drive.  If already on a low flow upon arrive, mirror that amount, or provide 2LPM.
