Question

A patient receiving high frequency oscillation ventilation (HFOV) has demonstrated excess CO₂ retention on a recent arterial blood gas. Which of the following could be adjusted to correct this situation?

A. Mean airway pressure
B. Amplitude (∆P)
C. Inspiratory time
D. Oxygen concentration

Answer 1

To correct excess CO₂ retention in a patient receiving HFOV, adjustments can be made to Mean Airway Pressure, Amplitude, Inspiratory Time, and Oxygen Concentration.

Step-by-step explanation:

To correct excess CO₂ retention in a patient receiving High Frequency Oscillation Ventilation (HFOV), adjustments can be made to several parameters including Mean Airway Pressure, Amplitude (∆P), Inspiratory Time, and Oxygen Concentration.

In this situation, the excess CO₂ retention suggests inadequate ventilation. Increasing the Mean Airway Pressure or Amplitude can help improve ventilation by increasing lung expansion and promoting CO₂ elimination. Adjusting the Inspiratory Time can also enhance ventilation. Lastly, modifying the Oxygen Concentration may help in improving gas exchange.
