1. Measurement of static and dynamic compliance during mechanical ventilation. A tidal volume is delivered, causing a peak in airway pressure; dynamic compliance is calculated at the peak inspiratory pressure (PIP). A short pause is applied before expiration to eliminate airway pressure caused by gas flow, and airway pressure decreases to a plateau (PPLAT). Static compliance is calculated during the plateau. A. Normal response. B. Low lung compliance causes a global increase in airway pressure and a decrease in both static and dynamic compliance. C. High airway resistance increases peak airway pressure but does not change the plateau pressure; dynamic compliance is decreased but static compliance is unchanged.
