Say the words “aneroid sphygmomanometer” to most people in the country, and they will look at you confused. Say them to any person in the medical community, and they will immediately know you are talking about a blood pressure monitoring device. Aneroid sphygmomanometers are comprised of an inflatable cuff that collapses then releases the artery under the cuff in a precisely controlled manner.
Inside of the device, a mercury or mechanical manometer is used to measure the pressure in conjunction with a device to measure the pressure where blood flow is just starting and at what pressure it is unimpeded. Manual aneroid sphygmomanometers are used with a stethoscope to hear these points.
- Needs and Price: The right sphygmomanometer is determined by the needs and requirements of its user.
- Accuracy: As with any medical instrument, the accuracy of measurements is of utmost importance.
- Quality, Design, and Cuff Size: Sphygmomanometers vary according to their quality of material and design, all of which affect the overall performance of the device.
