However with the benefits that automated bp devices provide with a repeatable standardized technique and removal of observer bias there has been a shift towards automated devices in clinical practice.
Blood pressure measurement technique.
Blood pressure values are generally reported in millimetres of mercury mmhg though aneroid and electronic devices do not contain mercury.
It is measured in millimeters of mercury mmhg above the surrounding atmospheric pressure.
Inflate the cuff 20 30 mm hg above this level to determine bp.
The arm being used should be relaxed uncovered and supported at the level of the heart.
3 have the patient stand.
Don t talk during the measurement.
If you use the auscultation method prefer a palpated estimate of radial pulse obliteration pressure to estimate sbp.
Ambulatory blood pressure monitoring is a noninvasive automated process that records blood pressure over an extended period.
Evaluation of blood pressure is essential in assessing cardiovascular health.
Proper positioning is vital in obtaining accurate blood pressure readings.
2 measure blood pressure and pulse rate.
Separate repeated measurements by 1 2 minutes.
The inflatable part of the cuff should completely cover at least 80 of your upper arm and the cuff should be placed on bare skin not over a shirt.
In general blood pressure should be measured while you are seated comfortably.
Measuring orthostatic blood pressure a drop in bp of 20 mm hg or in diastolic bp of 10 mm hg or experiencing lightheadedness or dizziness is considered abnormal.
4 repeat blood pressure and pulse rate measurements after standing 1 and 3 minutes.
Blood pressure is usually expressed in terms of the systolic pressure maximum pressure during one heartbeat over diastolic pressure minimum pressure between two heartbeats in the cardiac cycle.
Typically readings are taken every 15 to 30 minutes for 24 hours.
It is used in screening for hypertension and for monitoring the effectiveness of treatment in patients with.
During the measurement sit in a chair with your feet on the floor and your arm supported so your elbow is at about heart level.
