WebWhat is set inspiratory pressure on ventilator? During inspiration, the ventilator adjusts the flowrate to keep the airway pressure at the set level. The clinician sets the peak inspiratory pressure (PIP), respiratory rate (f), inspiratory time (T I ), positive end expiratory pressure (PEEP) and fraction of inspired oxygen (F I O 2 ). WebAt the time of the missed effort, a positive deﬂection in the airway ﬂow waveform (black arrow) and a negative deﬂection in the airway pressure (Paw) (red arrow) can be noted. Observe that in every ventilator breath, there is a time gap (delayed triggering) between the start of neural inspiration (ﬁrst dotted line) and the start of
