    • Colorless, odorless, tasteless gas essential to respiration
    • At sea level, oxygen makes up approximately 10% - 16% of venous blood and 17% - 21% of arterial blood
    • Transported from the lungs to the body’s tissues attached to hemoglobin in the red blood cells
    • Inhalation/administration will increase arterial oxygen tension (PaO2) and hemoglobin saturation
  3. Medical Oxygen
    Contraindications:
    None for emergency use.
  4. Medical Oxygen
    Indications:
    • Hypoxia from any cause
    • Chest pain due to cardiac ischemia

    None
  6. Medical Oxygen
    Dosing
    (Onset,Duration,Adult Dosage,Pediatric Dosage,Route)
    • Onset: immediate
    • Duration: until administration ceases
    • Dosage: Nasal Cannula: @ 1-6 L/min (24% - 40% O2 concentration)
    • Simple & Pocket Mask: @ 6 – 10 L/min (40% - 60% O2 concentration)
    • Partial/ Non-Rebreather (NRB): @ 10 – 15 L/min (up to 98% O2 concentration)
    • Bag-Valve Mask (BVM): @ 10 – 15 L/min (up to 100% O2 concentration)
    • Venturi Masks: @ 4 L/min (24% - 28% O2 concentration) @ 8 L/min (35% - 40% O2 concentration) Note: liter flow is dependent on the Venturi mask used.
    • Route: Inhalation
  7. Interactions/Precautions:
    • In some cases of COPD, oxygen administration may reduce the patient’s respiratory drive This is not a reason to withhold oxygen, but be prepared to assist ventilations.
    • Oxygen that is not humidified may dry out or irritate mucous membranes
    • Monitor long-term high flow in neonates as retrolental fibroplasia may develop
    • Open flames
    • 1 L/minute increase from 25% = 4% increase in dose
    • Example:
    • 1 L/minute = 25%
    • 2 L/minute = 29%
