1. ESV + normal venous return will increase the end diastolic volume ). 2. Increased venous return stretches the walls of the atria where specialized baroreceptors are located. 3. Jet pilots wear pressurized suits to help maintain their venous return and blood pressure. 4. Mean circulatory pressure has no physical meaning as a driving pressure behind venous return . 5. The water-filled, pulsatile pressure suits were developed to effect venous return . 6. As venous return increases, the pressure in the superior and inferior vena cava increase. 7. Superimposition of the cardiac function curve and venous return curve is used in one hemodynamic model. 8. Administration of amyl nitrite will also accentuate the murmur by decreasing venous return to the heart. 9. Nitric oxide is a potent pulmonary vasodilator, and thus reduces PVR and improves venous return . 10. Similarly, airway patency and venous return may be compromised by circumferential burns involving the neck.
