Question

Which mode of mechanical ventilation requires the nurse to monitor closely for auto-PEEP (positive end-expiratory pressure)?

1) Inverse ratio ventilation
2) Pressure support ventilation
3) Intermittent mandatory ventilation
4) High-frequency jet ventilation

Answer 1

Inverse ratio ventilation is the mode of mechanical ventilation that requires close monitoring for auto-PEEP by the nurse. Auto-PEEP occurs due to inadequate exhalation time, which can lead to increased work of breathing and potential lung injury.

Step-by-step explanation:

The mode of mechanical ventilation that requires the nurse to monitor closely for auto-PEEP (positive end-expiratory pressure) is 1) Inverse ratio ventilation. Auto-PEEP can occur during mechanical ventilation when there is inadequate time for the lungs to exhale fully before the next breath is initiated. Inverse ratio ventilation involves extending the inspiratory phase and shortening the expiratory phase, which can increase the risk of air trapping and the development of auto-PEEP. It is important for the nurse to be vigilant in monitoring for this condition, as it can lead to increased work of breathing and potential for lung injury. This situation is especially concerning in patients with chronic obstructive pulmonary disease (COPD) or asthma, where expiratory flow rates can be compromised.
