Question

A clinician used a stethoscope and a sphygmomanometer to determine a participant's blood pressure. With these two instruments, the clinician found the participant's diastolic pressure to be 85 mmHg and the systolic pressure to be 125 mmHg.

Based on Passage, find the participant's:
a. blood pressure.
b. pulse pressure.
c. mean arterial pressure (MAP).

Answer 1

The participant's blood pressure is 125/85 mmHg, with a pulse pressure of 40 mmHg, and a mean arterial pressure (MAP) of approximately 98.33 mmHg.

Step-by-step explanation:

When measuring the participant's blood pressure, which consists of two components: systolic pressure and diastolic pressure, the clinician used both a stethoscope and a sphygmomanometer. The systolic pressure is the pressure in the arteries when the heart beats and the diastolic pressure is the pressure in the arteries when the heart rests between beats. Accordingly, the participant's blood pressure is expressed as the systolic pressure over the diastolic pressure, which is 125 mmHg over 85 mmHg or 125/85 mmHg.

The participant's pulse pressure, which is the difference between the systolic and diastolic pressures, can be calculated by subtracting the diastolic pressure from the systolic pressure: 125 mmHg - 85 mmHg = 40 mmHg.

To calculate the participant's mean arterial pressure (MAP), we use the formula MAP = Diastolic Pressure + (1/3) x Pulse Pressure. By plugging in the values, we get MAP = 85 mmHg + (1/3) x 40 mmHg, which amounts to approximately 98.33 mmHg.
