This doesn’t affect heart rate
|
Detailed explanation-1: -A significant drop in blood pressure and changes in mental status occurs. Heart rate and respiratory rate are significantly elevated (more than 120 BPM).
Detailed explanation-2: -The most immediate change is that the heart rate will increase as the body tries to get more blood to the vital organs. The blood pressure will also decrease, leading to hypoperfusion of the tissues, which means that insufficient oxygen and nutrients are getting delivered to the cells.
Detailed explanation-3: -The initial compensatory responses to reduced circulating blood volume due to hemorrhage is an increased heart rate and systemic vascular resistance in order to maintain perfusion to vital organs (Gutierrez et al. 2004).
Detailed explanation-4: -A wound that is deep, bleeding heavily, or has blood spurting from it (caused by bleeding from an artery), may not clot and may not stop bleeding. Call out for someone to get help, or call 911 yourself. Elevate the wound and apply direct pressure.
