Study Notes
Blood Pressure Measurement Procedure and Interpretation
- The blood pressure procedure should be performed on bare skin and the sleeves should not be rolled up, to avoid excessive constriction of the upper arm.
- To measure blood pressure, palpate the brachial artery just below the bend of the elbow, then center the bladder of the cuff over the arm, with the lower edge of the cuff 1 inch above the bend of the elbow.
- If performing palpable systolic pressure, locate and palpate the patient's radial artery at the wrist, inflate the cuff to 30mmHg above the level which the radial pulse disappears, and take note of this reading.
- An auscultatory gap, a period of diminished or absent sounds during the manual BP measurement, may be found, particularly in cases of arteriosclerosis.
- In case palpable systolic pressure is not used, the cuff should be inflated to 160-180mmHg, and if after inflating to 180mmHg a sound is still heard, the cuff should be inflated more until the sound disappears.
- Korotkoff sounds, which are arterial sounds heard through the stethoscope on the brachial artery distal to the sphygmomanometer cuff, are used to determine systolic and diastolic blood pressure.
- Diurnal variations in blood pressure are normal, with the highest readings in the midmorning and lowest during sleep, and a 5-10mmHg discrepancy between the two arms is also normal.
- False high or low blood pressure readings can be caused by various factors such as cuff size, arm position, and diastolic and systolic measurement techniques.
- The cuff should be about 80% of the arm circumference, and arm position can affect the blood pressure measurement.
- Expected blood pressure readings are categorized as low, normal, elevated (prehypertension), hypertension stage 1, hypertension stage 2, or hypertensive crisis, based on systolic and diastolic measurements.
- Guidelines are provided for action based on arterial blood pressure readings, including when to continue with the examination, repeat blood pressure measurement, or refer the patient for immediate evaluation and treatment.
- Pulse rate, which gives information about heart rate, pattern of beats, and pulse strength, can be measured and interpreted to identify potential problems.
