Question

Systolic pressure of a person was recorded to be 118, while the diastolic
pressure was found
to be 70. Name the instrument that recorded this reading

Answer 1

The instrument that recorded this reading is - Sphygmomanometer.

1. Systolic pressure of a person measures the pressure with which blood is forced against the arteries of wall. Here the contraction of heart occurs.
2. Diastole pressure of a person measures the pressure with which heart refills the blood.
3. The normal systolic and diastolic blood pressure should be 120/80.
4. The cardiac cycle is the cycle from one heartbeat to next heartbeat and it begins with atrial systole continues to ventricular systole then to atrial diastole, and subsequently ventricular diastole.

Answer 2

Instrument recording blood pressure is SPHYGMOMANOMETER.

• It is mainly of two types : 1. Mercury based SPHYGMOMANOMETER 2. Aneroid (dial) SPHYGMOMANOMETER.

• It helps us to find out the SYSTOLIC AND DIASTOLIC blood pressure.

Systolic blood pressure: It is the blood pressure when the ventricles of the heart are contracting.

Diastolic blood pressure: It is the blood pressure when the heart is relaxing (not contracted).

Pulse Pressure: It is the difference between systolic blood pressure and diastolic blood pressure.

PP = SBP - DBP

Mean arterial pressure:

It is one third of pulse pressure added with diastolic blood pressure.

MAP = DBP + ⅓(PP)
