The beach chair (barbershop) position ?? what are the effects ?? Mean arterial pressure (MAP), central venous pressure (CVP), pulmonary artery occlusion pressure (PAOP), stroke volume, cardiac output, and PaO2 all decrease while e alveolar-arterial oxygen gradient (PAO2-PaO2), pulmonary vascular resistance, and total peripheral resistance increase. Cerebral perfusion pressure (CPP) decreases by approximately 15% in the sitting position in non-anesthetized patients and could further decrease under anesthesia because of vasodilation and impaired venous return.
