How is the anaerobic threshold physiologically related to outcomes in cancer patients
Oxygen demand increases 10 to 50% from surgery. Anaerobic metabolism can exacerbate tissue injury and indicates decreased ability to deliver and oxygen impairing tissue perfusion.
How is the VE/VCO2 slope physiologically related to outcomes in cancer patients?
Ventilatory efficiency reduces increasing demand on the heart to make up for it. Anaesthetic can depress ventilatory drive which if already poor can lead to hypoxemia.
