Blood Pressure Monitor Accuracy
- All with hypertension should have home blood pressure monitors.
- Home monitoring can give more accurate readings, avoiding stress of doctor visit.
- Closer monitoring allows doctors to fine tune medicines, as with diabetics.
- Aneroid monitor
- Digital monitor
- Finger or Wrist blood pressure monitor
Digital monitors have either manual or automatic cuffs. The blood pressure reading flashes on a small screen, and is therefore easy to read. Some electronic monitors even give you a printout of blood pressure reading. The digital monitor is easier to use than an aneroid one. It has a gauge and stethoscope as one unit, an error indicator, and deflates automatically.
This device is good for hearing impaired patients, as there is no need to listen to heart sounds through the stethoscope.
However, this equipment has some disadvantages too. The accuracy is changed by body movements or an irregular heart rate. The monitor also requires batteries, and some of its models are designed for use only with the left arm.
Finger or wrist monitors, as tests reveal, do not measure blood pressure accurately. Also, they are extremely sensitive to position and body temperature, and more expensive compared to other monitors.
