Can a sphygmomanometer be calibrated?
All sphygmomanometers should be checked and calibrated by an accredited laboratory at least annually. Aneroid sphygmomanometers should be calibrated every 6 months. Only properly validated automatic sphygmomanometers should be used.
How do you service a sphygmomanometer?
Use one or more of the following methods and allow to air dry:
- Wipe with mild detergent and water solution (1:9 solution). Rinse.
- Wipe with Enzol per manufacturer’s instructions. Rinse.
- Wipe with .
- Wipe with 70% isopropyl alcohol.
- Launder with mild detergent in warm water, normal wash cycle.
How long does a sphygmomanometer last?
Most home blood pressure machines last for about two or three years. After that, check it at your doctor’s office annually to make sure it’s still accurate.
Can blood pressure cuffs be calibrated?
Although home blood pressure monitors are calibrated at the factory, Goalen says they also need to be calibrated and adjusted to fit the individual who will be using the device. She doesn’t recommend using wrist or finger units because they cannot be adjusted for the user.
How often should blood pressure machines be calibrated?
Automatic electronic sphygmomanometers produce systematic errors in some patients. All sphygmomanometers should be checked and calibrated by an accredited laboratory at least annually. Aneroid sphygmomanometers should be calibrated every 6 months. Only properly validated automatic sphygmomanometers should be used.
How do I know if my BP machine is accurate?
Before buying a blood pressure monitor, check with your doctor to be sure the monitor has been validated — meaning its readings are accurate and repeatable. Once a year, check the accuracy of your monitor by bringing it to your doctor’s office and comparing your monitor’s readings with those taken by the doctor.
How often should a blood pressure machine be calibrated?
Keep your home blood pressure monitor calibrated Automatic blood pressure monitors need to be re-calibrated at least once every two years – the instructions that come with your monitor will say how often. This is where the monitor is tested and adjusted to make sure it’s giving you accurate results.
Why is my sphygmomanometer not working?
It is likely that the air valve on your cuff is jammed. There are two issues that may contribute to this problem; either the valve has become clogged with dust or debris, or an internal component called the ‘slit stopper’ has become bound from an extended lack of use.

How do you test a sphygmomanometer with a thumb valve?
Twist the thumb valve to the left slowly, and begin deflating the cuff at approximately 2 mmHg per second. Watch the movement of the gauge. Close the valve when the reference manometer reads 100 mmHg. Check the gauge of the sphygmomanometer and record if there is any change. Look at the numbers you have recorded.
Why is it important to calibrate a sphygmomanometer?
High blood pressure, also referred to as hypertension, cause the heart to work harder to overcome increased pressure in the arteries. A sphymomanometer uses a gauge containing mercury to measure pressure. It is important to calibrate your sphygmomanometer at least every 12 months to ensure its readings are accurate.
How do you deflate a sphygmomanometer?
Twist the thumb valve to the left slowly, and begin deflating the cuff at approximately 2 mmHg per second. Watch the movement of the gauge. Close the valve when the reference manometer reads 100 mmHg. Check the gauge of the sphygmomanometer and record if there is any change.
How do you put a bulb in a sphygmomanometer?
Insert the bulb into the other end of the Y-connector. Open the thumb valve by twisting it all the way to the left. Ensure the cuff is completely deflated. Look at the gauges of the sphygmomanometer and the manometer 1.
