Mean airway pressures can be increased by which of the following factors?
1) Increasing the inspiratory time
2) Increasing compliance
3) Increasing level of PEEP
4) Changing from a square to a decelerating ramp waveform

Question

Quizplus · Accepted Answer

Increasing inspiratory time and level of PEEP directly contribute to an increase in mean airway pressure (MAP) while increasing compliance indirectly increases MAP. Changing to a decelerating ramp waveform may improve gas distribution but does not have a direct effect on MAP. Therefore, choices 1, 3, and 4 would increase MAP, making option B the correct choice.
