Q. There is a structural difference in the atrioventricular valves in the left and right heart.

Q. The semilunar valves in the left and right heart both contain three cusps.

Calculating mean arterial pressure

The mean arterial pressure (MAP)

is the average pressure throughout the cardiac cycle (one beat of the heart).

Q. From the two options given below, select the equation that will give the most accurate estimation of mean arterial pressure (MAP).

Q. A patient has a BP of 110/80 mmHg. What is this patients MAP?

Class Results

The table below shows an example of results

obtained by students during this class. Examine these results and answer the questions:

Q. The table shows a reasonable level of variation in blood pressure recordings amongst students; this is unusual in a cohort of young healthy adults.

Q. The students with a blood pressure recording of less than 120/80 have low blood pressure (hypotension)

Q.

The class results show an overall difference between the blood pressures obtained by auscultation and those obtained by palpation. The auscultation method always gives a more accurate measure

of systolic pressure.

Q.

The class results show a higher average blood pressure amongst the

male students compared to the female students. This result is expected.

Q. The blood pressures of several students were recorded as being in the high range. If these results were recorded by a doctor, a diagnosis of hypertension would be made.
