B) pulmonary capillary wedge pressure
C) spirometry
D) thoracentesis

Question

Quizplus · Accepted Answer

Capnography is a noninvasive study that assesses the amount of carbon dioxide in the arterial system of a patient on mechanical ventilation. Pulmonary capillary wedge pressure measures the pressure in the left atrium and is not directly related to carbon dioxide levels. Spirometry measures lung function through the evaluation of breathing patterns and volumes. Thoracentesis is a procedure used to remove fluid from the space between the lungs and the chest wall, and is also not directly related to carbon dioxide levels.
