DETERMINATION OF BLOOD PRESSURE

Updated on April 3, 2016

Requirements

a) Clinical Mercury Sphygmomanometer

b) Stethoscope

Source

Precaution

a) Don’t apply pressure above 140mmHg because it may obstruct blood vessel blood flow resulting in paralysis.

b) The subject should be seated at a comfortable position.

c) The cuff should be inflated until the artery is completely occluded.

Procedure

a) Wrap the sphygmomanometer’s cuff smoothly and snuggly around the upper arm at roughly the same height as the heart. In the manner that the rubber part is on the inside and rubber tubes emerge from the lower side of the arm.

b) Inflate the cuff to about 140mmHg, i.e. until arterial blood is completely occluded.

c) Listen with the stethoscope at the brachial artery at the elbow.

d) Slowly relieve the pressure at the cuff.

e) Note and record the first sound as the systolic blood pressure.

f) Systolic blood pressure is read by releasing the pressure until a radial pulse is felt.

CONCLUSION

The peak pressure during the cardiac cycle is the systolic pressure, and the lowest pressure is the diastolic pressure. Measurement of blood pressure is carried out in the diagnosis of hypertension.
