Blood Pressure Measurement

Blood Pressure

Measurement of the pressure that the blood exerts on the walls of the arteries as the heart contracts or relaxes.

Necessary To Measure Blood Pressure Following Tools

Sphygmomanometers

 

Types of Sphygmomanometers

Digital

   

Pulse Pressure

•Difference between the systolic and diastolic pressure

•Important indicator of the health and tone of arterial walls

•Normal range for pulse pressure in adults is 30 to 50 mm Hg

•Ex: If the systolic pressure is 120 mm Hg and the diastolic pressure is 80 mm Hg, the pulse pressure is 40 mm Hg

PROCEDURE

•Preparation:

–Prepare the patient

–Prepare the room and equipment

•Greet the pt and give information (ask permission)

•Close the curtain

•Roll up the sleeve

•Place the arm at heart level

•Find and feel the brachial pulse (artery)

•Wrap the upper arm with rubber cuff

•Secure the position of the cuff

•Open the valve of stethoscope. Place the diaphragm (bell) on brachial pulse

•Lock the valve of sphygmomanometer and pump (squeeze) the bulb to inflate the cuff

•Unlock the valve slowly and listen to the pulse.

•Check (look at) the manometer (scale) to identify the systolic (first “lupp” sound) and diastolic (last “dubb” sound) pressure.

•Unlock the valve totally to release the air in the cuff.

•Remove the cuff.

•Inform the result to the patient

•Document (record) the result on medical record

•Tidy the equipment and patient.

•Inform about the result to the patient and doctor
