BP Monitor

Finger blood pressure monitor

There are a number of different types of blood pressure monitors, ranging from the traditional and reliable sphygmomanometer, to the more advanced digital BP monitors that measure your blood pressure. There are different types of digital BP monitors. Examples are wrist monitors, arm monitors and even finger monitors.

What is a finger blood pressure monitor? It is a device applied to the patient's finger and used to measure the blood pressure. It is a digital device that does not require any cuffs, and can measure blood pressure from an individual’s finger.

 How is a finger blood pressure monitor different from a normal digital BP monitor? A normal digital BP monitor uses an inflatable cuff that inflates and deflates automatically. A finger BP monitor, on the other hand measures the BP from the finger. All the user has to do is to insert a finger into the device.

Although there are obvious advantages of using a finger blood pressure monitor, there are some margins of error in a BP reading that you get from such a device.

The following are the disadvantages of using a finger BP monitor.

These monitors may not be as accurate as other digital monitors or the traditional sphygmomanometer. The device is may give different results depending on whether you have correctly inserted your finger into it. If your finger is not in the right place, the device may not provide correct results.
These devices are very expensive when compared to other types of BP monitors.

Another problem faced by users of this type of monitor is that it is extremely sensitive to the patient's body temperature.

Finger BP monitors are digital in nature. These devices, as is the case with all digital BP monitors may need to be calibrated every now and then to eliminate any margin of error.

In order to check a finger BP monitor for accuracy, ad if you get the chance, take the monitor that you are planning to buy to your doctor’s clinic and check its accuracy.
