Ventilatory support strategies likely to result in auto-positive end expiratory pressure (PEEP) include which of the following?
1) Continuous mandatory ventilation (CMV) assist-control
2) Inverse ratio ventilation (IRV)
3) Low-rate intermittent mandatory ventilation
4) Low inspiratory flows

Question

Quizplus · Accepted Answer

Continuous mandatory ventilation (CMV) assist-control and low-rate intermittent mandatory ventilation both utilize controlled breaths that maintain a set tidal volume. Low inspiratory flows can also result in auto-PEEP. Inverse ratio ventilation (IRV) increases inspiratory time compared to expiratory time, which can be beneficial in some cases but can also lead to auto-PEEP. Therefore, choices 1, 3, and 4 are likely to result in auto-PEEP.
