Corrected End-Tidal PCO2 Accurately Estimates PaCO2 at Rest and During Exercise in Morbidly Obese Adults

PJCO2 provides a better estimate of PaCO2 than PETCO2 during submaximal exercise and at peak exercise, whereas at rest both yield reasonable estimates in morbidly obese individuals. Clinicians and physiologists can obtain accurate estimations of PaCO2 in morbidly obese individuals by using P jco 2 .
