What is the formula for mean arterial blood pressure (MAP) according to the text?
What is the formula for mean arterial blood pressure (MAP) according to the text?
- $MAP = SBP - DBP$
- $MAP = 2/3 SBP + 1/3 DBP$
- $MAP = (2/3 SBP) - (1/3 DBP)$
- $MAP = (1/3 SBP) + (2/3 DBP)$ (correct)
What is the definition of systolic pressure?
What is the definition of systolic pressure?
- The peak pressure exerted in the arteries when blood is pumped into them during ventricular systole. (correct)
- The average pressure responsible for the driving blood forward through the arteries into the tissues throughout the cardiac cycle.
- The lowest pressure exerted in the arteries when blood is draining off into the vessels downstream during ventricular diastole.
- The difference between the systolic and diastolic pressure.
What is the historical emphasis regarding diastolic and systolic blood pressure?
What is the historical emphasis regarding diastolic and systolic blood pressure?
- More emphasis was historically placed on systolic than on diastolic blood pressure.
- More emphasis was historically placed on diastolic than on systolic blood pressure. (correct)
- Historically, blood pressure emphasis was not significant.
- Equal emphasis was historically placed on both systolic and diastolic blood pressure.
