Does a Blood Pressure Machine Need to 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 do I know if my blood pressure monitor is accurate?

Check for accuracy

“If the systolic blood pressure (the top number) on your cuff is within 10 points of the monitor, then it's generally accurate,” he says. 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.

How often should a blood pressure monitor 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.
