The condition that is associated with an increase in airway resistance is which of the following?
A) Pulmonary edema
B) Bronchospasm
C) Fibrosis
D) Ascites

Question

Quizplus · Accepted Answer

Airway resistance is determined by the gas viscosity,gas density,tubing length,airway diameter,and the flow rate of the gas through the tubing.The two factors that are most often subject to change are the airway diameter and the flow rate of the gas.The flow rate of the gas during mechanical ventilation is controlled.Pulmonary edema is fluid accumulating in the alveoli and will cause a drop in the patient's lung compliance.Bronchospasm causes a narrowing of the airways and will,therefore,increase the airway resistance.Fibrosis causes an inability of the lungs to stretch,decreasing the patient's lung compliance.Ascites causes fluid buildup in the peritoneal cavity and increases tissue resistance,not airway resistance.
