Blood pressure help
- 0Apr 11, '12 by lizzie1991What must the systolic blood pressure be valued at for adequate mean arterial pressure if the diastolic pressure is 75? (resting conditions assumed)
at least 90? 95? 100? 105? 110? 115? 120?
Which of those (only one of them) is correct?
I'm confused.Last edit by lizzie1991 on Apr 11, '12
- 1Apr 11, '12 by GrnTea, BSN, MSN, RNdid they give you a formula for calculating mean arterial pressure and tell you what they think is "adequate"? if so, what it's asking you is to plug those numbers into the formula (using the 75 for the diastolic) and see which one is the answer.
at normal resting heart rates, map can be approximated by the following equation (thank you, wikipedia):
this says, "mean arterial pressure is approximately equal to diastolic plus 1/3 (systolic minus diastolic)"
