Detailed explanation-1: -Acute meal ingestion, caffeine or nicotine use can all affect BP readings, leading to errors in measurement accuracy. If the patient has a full bladder, that can lead to an error in systolic BP of up to 33 mm Hg, and the white-coat effect can have an error of up to 26 mm Hg.
Detailed explanation-2: -Incorrect patient positioning Perhaps the most common mistake in blood pressure measurement is allowing patients to sit or lie with their arms hanging by their side, since when the upper arm is below the level of the right atrium, the readings will be too high.
Detailed explanation-3: -There are three sources of error in the indirect measurement of blood pressure: (1) observer bias, (2) faulty equipment, and (3) failure to standardize the techniques of measurement.
Detailed explanation-4: -Most blood pressure reading errors are the result of improper sizing of the blood pressure cuff or placing the cuff over clothing. Improper placement of the cuff over clothing can cause your blood pressure measurement to increase by 10 to 50 points.
