Web5 de jan. de 2024 · In instances of higher airway resistance from some obstructive process, the flow scalar will show a decreased peak expiratory flow and a prolonged time for the expiratory curve to return to a baseline of zero flow (Fig. 2 b) [ 5 •]. All of this represents that the resistance to airflow is limiting how fast and how much volume the lung empties. WebThe volume delivered by the ventilator varies with changes in airway resistance, lung compliance, and integrity of the ventilatory circuit. Volume-cycled ventilators: Gas flows to the patient until a preset volume is delivered to the ventilator circuit, even if this entails a very high airway pressure.
