How to Take Blood Pressure Manually

Introduction:
Blood pressure is a crucial indicator of an individual’s overall health. Keeping track of one’s blood pressure regularly can help detect any potential health concerns early. This article will discuss how to take blood pressure manually using a sphygmomanometer and stethoscope.
Step 1: Preparation
1. Make sure the person whose blood pressure you are measuring is relaxed and seated comfortably with their legs uncrossed.
2. Ensure the individual has not consumed caffeine, smoked, or exercised within the last 30 minutes, as these factors can affect blood pressure readings.
3. Remove any tight clothing around the upper arm where the cuff will be placed.
4. Rest their arm on a flat surface, preferably at heart level.
Step 2: Positioning the Sphygmomanometer
1. Place the deflated cuff snugly around the person’s upper arm, ensuring it is situated about an inch above the elbow’s crease.
2. Position the artery marker (usually an arrow or dot) over the brachial artery.
3. Keep an eye on cuff placement and perform any necessary adjustments during inflation.
Step 3: Locating the Pulse
1. Place your fingertips on top of your patient’s elbow crease and gently press down to locate their brachial pulse.
2. Once you locate it, make note of this spot for stethoscope placement.
Step 4: Positioning the Stethoscope
1. Place the diaphragm (larger side) of your stethoscope against their skin in the spot where you felt their brachial pulse.
2. Make sure you have a good seal by pressing down gently on the stethoscope to avoid ambient noise interference.
Step 5: Taking Blood Pressure Reading
1. Close off the airflow to your sphygmomanometer bulb by turning the air-release valve clockwise.
2. Inflate the cuff by pumping the bulb steadily until the pressure gauge reads about 30 mmHg higher than their expected systolic pressure.
3. Slowly release air from the cuff by loosening the valve counterclockwise while listening through the stethoscope for the first heartbeat sound (Korotkoff Sound). This is your patient’s systolic blood pressure, expressed as “pressure over.”
4. Continue to release air slowly and note when you no longer hear these sounds – this is your patient’s diastolic blood pressure.
5. Wait a few moments before deflating the cuff entirely and removing it from their arm.
Step 6: Documentation
1. Document your findings as “systolic/diastolic” (e.g., 120/80). The systolic measurement is always mentioned first, followed by the diastolic.
2. Always note if there are any special circumstances during measurement, such as position changes or activity differences before taking a reading.
Conclusion:
Taking blood pressure manually using a sphygmomanometer and stethoscope is an essential skill for healthcare professionals or anyone looking to keep close tabs on their health. Remember to practice as it improves both skill and accuracy when measuring blood pressure manually.
