➪ Practice Point:
- The client should be seated comfortably for five minutes with the back supported and the upper arm bared without constrictive clothing. The legs should not be crossed.
- The arm should be supported at heart level, and the bladder of the cuff should encircle at least 80% of the arm circumference (Pickering et al., 2005).
- The mercury column should be lowered at a rate of 2 to 3 mmHg/sec, and the first and last audible sounds should be taken as systolic and diastolic pressure. The column should be read to the nearest 2 mmHg.
- Neither the client nor the observer should talk during the measurement.
- No smoking or nicotine in preceding 15-30 min.
- No caffeine in the preceding hour.
