Which of the followingwould causean increase patient peak airway pressure

high(passive) is caused byThe increase in the peak airway pressure

any drugcausingAIRWAY PEAK PRESSURE INCREASED

the diminished dead spaceresultsfrom the drop in peak airway pressure

High tidal volume ( V T ) andmay leadincreased airway pressure

High tidal volume ( VT ) andmay leadincreased airway pressure

Pneumothoraxcan causeincreased airway pressure

the resistance is increasedleadingto high airway pressure

a closed glottiscausesan increase in airway pressure

The square / rectangular waveform in VC , which maintains a fixed flow throughout the inspiration with higher flows at end - inspiration compared to PC and PSleadsto a higher peak airway pressure

All 3 settingsleadto increase in peak airway pressures
