The oxyhemoglobin dissociation curve shifts to the right, allowing increased tissue oxygen availability. □ Cessation for 4 to 6 weeks before surgery has been shown to decrease the incidence of postoperative pulmonary complications. □ Cessation for 2 to 3 months before surgery results in all of ...
shift to the right (redirected fromdeviation to the right) shift [shift] a change or deviation. antigenic shifta sudden, major change in the antigenicity of a virus, seen especially ininfluenzaviruses, resulting from the recombination of thegenomesof two different strains; it is associated with ...
If the diffusive component of O2 transport in muscle is important in determining exercise capacity, an increased capillary-to-tissue PO2 difference should enhance gas exchange from blood to skeletal muscle during exercise. Thus a rightward shift in the O2 dissociation curve should theoretically increas...
(c) oxygen saturation test: a truly wedged catheter will yield a mixed venous oxyhemoglobin saturation reflective of the postcapillary pulmonary bed, typically greater than 90% to 95%, while lower values should prompt repeat attempts to wedge, including alternate vascular areas or consideration of ...
