Following these guidelines will help you get the most accurate readings from the aneroid sphygmomanometer while avoiding some of the most common mistakes.
Do’s for using Aneroid Blood Pressure Monitor
Keep cuff at one place
The secondary examination should begin with the patient sleeves up so that the blood pressure can be measured. This will help to keep the cuff firmly in place. In order to avoid an inaccurate reading, your blood pressure cuff must never be worn over clothing during the examination.
Position your patient properly
The patient’s legs should not be crossed, and they should be seated comfortably. The arm should be supported while the blood pressure is being measured in an artery that is close to the heart.
Choose the right cuff
80 percent of the circumference of the patient’s upper arm should be able to be encircled. The cuff is too narrow for the patient if it takes 80% of the cuff for wrapping around the upper arm, resulting in an inaccurate reading. For an accurate reading of aneroid sphygmomanometer, the cuff should cover at least 80 percent of the upper arm. If it doesn’t, the reading will be too low.
Palpate the artery
Feel for the brachial artery’s pulsation with one’s arm fully extended. This will make it difficult to locate the artery as well as audible Korotkoff sounds if the arm is not fully extended. The medial component of an antecubital fossa, in which the artery is closest to the skin, is where most people’s pulses can be felt.
Position your cuff properly
At the lower edge of the cuff, the lower margin should be placed 1 inch above where the heart rate is located. Getting the cuff too close or too loose isn’t that difficult to do in real life. In order to properly obstruct blood flow when inflating the cuff, pinpoint where bladder is fastened into the cuff and make sure that bladder is situated over the arterial.
Use palpation for estimating systolic blood pressure
Inflate the cuff till the radial pulse is no longer detectable. At this point, the sphygmomanometer should indicate that the pulse has returned. This is your systolic blood pressure as measured by palpation.
Inflate cuff up to 30 mmHg above palpated systolic pressure
Only inflate the cuff by 30 millimetres above the palpable pressure, not more or less. This prevents the cuff from being under- or over-inflated.
Look straight on sphygmomanometer
At an angle, a parallax error can occur, which is an incorrect measurement due to the effects of optics.
Don’ts of aneroid blood pressure monitor
- Never inflate the cuff more than 30 mm or less than this
- Never wear the cuff over your clothes
- Never let your patient sit in a cross-leg position
- Do not wear a loose cuff during the blood pressure measurements, as it can give inaccurate readings
- Do not talking during blood pressure measurements
- Avoid smoking, exercising or drinking before 30 mins of your blood pressure measurement session
- Never measure readings back to back, take 1 minute break
Keep the above-mentioned Do’s and Don’ts in mind while using the aneroid blood pressure monitor for effective results.
