The respiratory care practitioner wants to check the airway resistance with an asthmatic patient on a ventilator.She can check airway resistance by which of the following?
A) Checking the inspiratory pressure time display for peak pressure.
B) Evaluating the volume time tracing for evidence of unevenness of filling
C) Dividing frequency by tidal volume in liters
D) Observing the slope of the expiratory flow tracing

Question

Quizplus · Accepted Answer

Airway resistance may be assessed by observing the slope of the expiratory flow tracing.A lower slope (smaller angle)is indicative of higher resistance to expiratory flow,while a steeper slope (greater angle)is indicative of lower resistance to expiratory flow.
