A member asked:

How does having a fever and dehydration affect a person's cardiovascular system?

Dr. Jason Adler answered

Specializes in Pediatric Critical Care

Fever: Fever and mild dehydration can cause an increase in heart rate to maintain cardiac output. Severe dehydration and fever can eventually overwhelm the ability of the body to maintain adequate cardiac output, resulting in low blood pressure, otherwise known as decompensated shock.
