Buffering of respiratory variations in venous return by right ventricle: a theoretical analysis.

The role of the right ventricle (RV) in buffering systemic venous return, thereby dampening respiratory-induced variations, left ventricular (LV) stroke volume, and systemic arterial pressure variations was examined using a computer model of the cardiovascular system. Respiration was simulated by cyclical variations in intrathoracic and abdominal pressures… CONTINUE READING
