Influence of ventilator settings on patient–ventilator synchrony during pressure support ventilation with different interfaces

摘要

Objective To evaluate patient–ventilator interaction during pressure support ventilation (PSV) delivered with three interfaces [endotracheal tube (ET), face mask (FM), and helmet (H)] at different pressurization times (Time_press), cycling-off flow thresholds (Tr_exp), and respiratory rates (RR) in a bench study, and with FM and H in a healthy volunteers study.
