Posture-induced hemodynamic shifts in obesity warrant caution; hypothesis-generating and should not yet change practice.
Does changing posture from sitting to supine alter cardiovascular and respiratory parameters in very obese patients?
In very obese patients, assuming a supine position significantly increases cardiac output and pulmonary pressures, likely due to reduced peripheral resistance and increased work of breathing.
Paul et al. (1976) studied this question.
