Is it OK to increase validation checks and decrease min gradient while training neural network?

Total peripheral resistance question please help in checking my answers?

• INSTRUCTIONS for questions 5 - 10: In answering these questions, assume that the pressure gradient across the systemic circuit is held constant even if the perturbation alters total systemic resistance. Also, since you have not yet studied compensatory cardiovascular reflexes, assume they do not exist when choosing your answer. * Answer A, if the perturbation increases total peripheral resistance. * Answer B, if the perturbation decreases total peripheral resistance. * Answer C, if the perturbation has no effect on total peripheral resistance. PERTURBATIONS: 5. As a result of pregnancy, blood flow through a woman's uterus greatly increases. decrease in TPR 6. A large release of catecholamines produces marked vasoconstriction of the splanchnic circulation. increase in TPR 7. A male experimental subject lies on his back and raises one leg. This maneuver causes most of the venous blood in that leg to drain into his abdominal veins. While the leg is still raised, a tourniquet is tightened on the upper thigh of the raised leg thus preventing blood from entering or leaving that leg. The leg (with blood flow still impeded) is then lowered. ok, so this dude's central venous pressure is lowered as a result of impeding venous blood flow. TPR=(MAP-MVP)/CO i would think this would be an increase in TPR. 8. Surgical production of an arterio-venous fistula in the wrist. no change in TPR? 9. Pronounced anemia reducing the hematocrit to half the normal value. (Assum blood flow remains streamlined). decreased TPR 10. Streptococcal infection causes the aortic valve to become stenotic ( its opening is narrowed). increased tpr any help is appreciated

• Answer:

  Those look correct except I would check on number 8 and 9. I am not sure that the tpr in anemia will change. It could even possibly go up. Also, on the av fistula, I would expect a slight drop in tpr.
