WebIf the exercise is intense, breathing rates may increase from a typical resting rate of 15 breaths per minute up to 40 – 50 breaths per minute. The most commonly used measure of respiratory function with exercise is known as VO 2 (volume of oxygen uptake). VO 2 refers to the amount of oxygen taken up and used by the body. WebJoshua Botdorf, Joseph L. Nates, in Perioperative Care of the Cancer Patient, 2024. Low Tidal Volume. Tidal volume size is associated with postoperative pulmonary complications in a dose-dependent fashion. Utilization of lung protective strategies using lower tidal volumes is widely endorsed with varying goals for PEEP in the reduction of …
WebTo further investigate the tidal volume (VT) response to exercise in severe COPD, nine patients were recruited to undergo a maximal incremental exercise test. Pulmonary function tests, collection of expired gases, and continuous pulse oximetry were performed. As a group, the results were as follows (mean +/- SD): The FEV1 was 31 +/- 7 percent ...
