    Study Notes

    Oxygen and Administration

    • Oxygen is a colorless, odorless gas making up 21% of the atmosphere.
    • It's crucial for cellular oxygenation.
    • Used to treat acute and chronic respiratory issues.
    • Aim for an oxygen saturation (SaO2) of 95-100% using the lowest possible oxygen flow to reduce complications.
    • Mechanical ventilation is needed for clients unable to breathe independently. This includes those with severe respiratory illnesses, under general anesthesia, experiencing trauma, or other conditions requiring respiratory support.

    Oxygen Delivery Devices

    • Supplemental oxygen is delivered via various methods based on individual client needs.
    • Oxygen concentration is expressed as the fraction of inspired oxygen (FiO2).
    • Monitoring vital signs, especially SaO2, is essential during oxygen therapy, intervening as necessary.

    Low-Flow Oxygen Delivery Systems

    • Provide variable oxygen levels based on the method and the patient's breathing.

    Nasal Cannula

    • Description: A tube with two prongs inserted into the nostrils.
    • FiO2: 24% to 44% at flow rates of 1 to 6 L/min.
    • Advantages: Safe, easy to apply, comfortable, and well-tolerated. Allows for eating, talking, and walking.
    • Disadvantages: FiO2 varies with flow and the client's breathing, extended use can cause skin breakdown and dry mucous membranes, and the tubing can be easily dislodged.
    • Nursing Actions:
      • Assess nostril patency and proper prong fit.
      • Use water-soluble gel to prevent dryness.
      • Provide humidification for flow rates of 4 L/min or greater.
