Measureme nt of Blood Pressure In ManPreLab Dr Sherwan Shal 2008

Switch off your Mobile phones PLZ!!I want to hear NOTHING !!!

Main Methods Direct : More accurate, but complicated. Indirect: Less accurate, easy to perform, sufficient.

Instruments (Sphygmomanometer) 1. Mercurial: Best, reliable, easy to mend, but large and heavy in weight. 3. Aneroid: less reliable, easy to handle and small and light in weight. 4. Electronic: easy to use, less reliable.

Mercurial Sphygmomanometer

Aneroid Sphygmomanometer

Electronic sphygmomanometer

Remember ; Pain and fear raise your BP !!

Methods For BP Estimation Palpatory: Using only sphygmomanometer. Auscultatory Method: Using Sphyg. + Stethoscope.

BP Measurement "Blood pressure" Systolic over diastolic About 120/80 mmHg

Sphygmomanometer "Estimate of pressure" Korotkoff sounds

Notes If a vessel is completely blocked: No flow, no pulse and no sound. If completely opened: There is flow, there is pulse but no sound. If the artery is partially closed (obstructed) then: There is flow, pulse and sound. Sound ONLY when there is partial

Normal Blood Pressure Depend on age and other factors: Young adult: Systolic 100-130 mmHg / Diastolic 60-90 mmHg Children: Systolic up to 100 and Diastolic upto 60 is normal. Elderly: up to 130/90 mmHg ( Increased because of atherosclerosis) Age + 100 is accepted for systolic , so , if some one is 50 years then systolic of 150 mmHg is normal. ( Diastolic upto 90 mmHg)

Pulse pressure = SystolicDiastolic Mean arterial pressure (MAP) = Diastolic + 1/3 pulse p
