An increase in peak inspiratory pressure (PIP)without an increase in plateau pressure (P_plateau)is associated with which of the following?

Question

Quizplus · Accepted Answer

The PIP represents the amount of pressure needed to overcome both elastance and airway resistance.The P_plateau is the amount of pressure required to overcome elastance alone.Since the P_plateau has remained constant in this situation,the static compliance is unchanged.The difference between the PIP and the P_plateau is the transairway pressure (P_TA)and represents the pressure required to overcome the airway resistance.If P_TA increases,the airway resistance is also increasing,when the gas flow rate remains the same.
