Lab 5 Measurement of Human Blood Pressure with Sphygmomanometer (Cont'd...)
Target organ damage:
Left ventricular hypertrophy (lv mass index >125 g/m2 in men, >110 g/m2 in women), carotid intima-media thickness (>0.9 mm), atherosclerotic plaque, serum creatinine (>1.3 mg/dl in men, >1.2 mg/dl in women), microalbuminuria.
Fasting plasma glucose 126 mg/dl, postprandial plasma glucose >200 mg/dl.
Associated clinical conditions:
Cerebrovascular disease (transient ischaemic attack, stroke, haemorrhage), heart disease (angina, myocardial infarction, heart failure), renal disease (diabetic nephropathy, serum creatinine >1.5 mg in men, >1.4 mg in women, protienuria >300 mg/24 hours), peripheral vascular disease, advanced retinopathy (haemorrhage, exudates, papilloedema).
Sphygmomanometer is kept at the level of heart of the subject and cuff is wrapped around the upper arm just above the elbow. The chest piece of the stethoscope is placed upon the brachial artery. The other ends of the stethoscope are connected with two ears. The bag of the cuff is filled by the pump up to 240 mm Hg. pressure. The pressure inside the cuff is released slowly by loosing the air with the air adjustment screw. As the pressure is released sudden appearance and disappearance of a sound is heard and recorded. Sudden onset of trapping sound is systolic blood pressure and the sudden disappearance of sound is diastolic pressure.
Name of Patient:
Systolic blood pressure:
Diastolic blood pressure:
The cuff should be wrapped tightly, the cuff bag should be air free, the apparatus should be kept at the level of heart, pumping and measuring should be done carefully.
