Gas Trapping Etiology
Pretest
Very short inspiratory times may lead to gas trapping.
A.True
B.False
Post test
Very short inspiratory times may lead to gas trapping.
A.True
B.False
Answer: B
Very short inspiratory times may lead to incomplete delivery of tidal volume and, therefore, lower peak inspiratory pressure and mean airway pressure, leading to hypercapnia and hypoxemia. Similarly, insufficient expiratory time may lead to increases in functional residual capacity and inadvertent positive end-expiratory pressure, which is evidence of gas trapping.
