Effect of different ventilator respiratory settings on the mean inspiratory airway pressure time product (PTPinsp) during HF-BiPAP, BiVent, and PSV ventilation. Data were measured during normal (compliance 90 ml/cmH2O, resistance 3 cmH2O/l/s), restrictive (compliance 30 ml/cmH2O, resistance 3 cmH2O/l/s), and obstructive lung conditions (compliance 90 ml/cmH2O, resistance 15 cmH2O/l/s) at low (2.5 cmH2O) and high inspiratory efforts (10 cmH2O) at a respiratory rate of 15 and 30 breaths per minute. BiVent = time-cycled pressure controlled switching between two continuous positive airway pressure levels; HF-BiPAP = high flow biphasic positive airway pressure; PSV = pressure support ventilation.
