    Study Notes

    Oxygen Therapy Definitions

    • PaO2: Partial pressure of oxygen in arterial blood, measured in mmHg.
    • FiO2: Fractional inspired oxygen content, the percentage of oxygen in the gas being measured. Atmospheric air has a FiO2 of 0.21, while pure medical oxygen has a FiO2 of 1.0.
    • SpO2: Saturation of peripheral oxygen, the percentage of hemoglobin in the blood that is saturated with oxygen.
    • Hypoxemia: Condition where arterial blood contains low amounts of oxygen (PaO2 less than 80 mmHg).
    • Hypoxia: Condition where oxygen delivery to the tissues falls short of cellular needs.

    Oxygen Delivery Devices

    • Nasal Cannula: Delivers low flow oxygen via prongs inserted into the nostrils; Typical flow rate is 1 to 6 LPM, corresponding to an FiO2 of 0.24 to 0.44.
    • Oxymask: Mask designed with a diffuser to concentrate and direct oxygen towards the mouth and nose; Can achieve high and variable FiO2.

    Variable FiO2

    • Variable FiO2: The FiO2 delivered can be adjusted to the patient's needs.
    • Fixed FiO2: The FiO2 delivered is a set value and cannot be adjusted easily.

    Oxymask

    • Manufacturer: Southmedic Inc.
    • Application: Used in hospitals when nasal cannula cannot achieve adequate oxygenation.
    • Flow Rates: Respiratory therapist (RT) titrates the oxygen flow to achieve desired patient saturations.
    • FiO2: Capable of high and variable FiO2.
