Article Synopsis
- Systemic vascular resistance decreases during exercise due to vasodilation in active muscles, leading to lower muscle oxygen levels and reduced response to constrictor signals (functional sympatholysis).
- Blood pressure is usually maintained or elevated during exercise through increased cardiac output and sympathetic activity, but recovery of normal oxygen levels and vascular tone in muscles post-exercise can be hindered in cases of shock or cardiopulmonary resuscitation.
- The main hypothesis suggests that exercise-induced vasodilation can worsen low blood pressure in shock situations, with sub-hypotheses indicating that recent exercise affects the onset of shock, the effectiveness of chest compressions during CPR, and the response to vasopressor medication.
