Oxygen Delivery Devices

Various oxygen delivery devices are available, depending on the client's condition and needs:

  1. Nasal Cannula: Low-flow device delivering 1-6 L/min, providing 24-44% oxygen concentration.
  2. Simple Face Mask: Moderate-flow device delivering 5-10 L/min, providing approximately 40-60% oxygen concentration.
  3. Venturi Mask: High-flow device with specific adapters delivering precise oxygen concentrations (24-60%) based on color-coded valves.
  4. Non-Rebreather Mask: High-flow device with a reservoir bag ensuring the client breathes pure oxygen, delivering 60-100% oxygen concentration.
  5. High-Flow Nasal Cannula (HFNC): Delivers heated and humidified oxygen at flow rates of up to 60 L/min, maintaining constant oxygen concentration and reducing airway resistance.

Correct Answer is C

Explanation

<p>Transtracheal catheter is a more invasive oxygen delivery method and is not commonly used in pneumonia management.</p>

<p>High-flow nasal cannula is effective in delivering precise oxygen concentrations and provides consistent oxygenation for clients with severe hypoxemia.</p>

<p>Oxygen tent is not commonly used in COPD management and is typically reserved for pediatric clients or those with specific respiratory conditions.</p>
