"Webb7 apr. 2024 · Volume-cycled mode. Inhalation proceeds until a set tidal volume (TV) is delivered and is followed by passive exhalation. A feature of this mode is that gas is delivered with a constant inspiratory flow pattern, resulting in peak pressures applied to the airways higher than that required for lung distension (plateau pressure).

Webb1 feb. 2024 · Flow Rate. The inspiratory flow rate is a rate that controls how fast a tidal volume is delivered by the ventilator. The setting can be adjusted depending on the patient’s inspiratory demands. The normal inspiratory flow … WebbCompliance (demonstrated by the pressure volume curve) is a measure of the distensibility of the lungs or ease with which the lungs inflate (i.e. the reciprocal of elastance). It is measured as the change of volume in the lungs in response to a change in pressure. Normal lung and chest wall compliance is ~1L per kPa (100 mL per cmH 2 O).
