Warning about the type of application for fingerprint blood pressure measurement is very dangerous

People 's smartphones are not "magic" enough to measure blood pressure with cameras and fingerprints. Yet this app still has over 1 million downloads, rating 4.6 *, it's scary.

Blood pressure story with phishing app

Recently, a Facebook user shared about catching patients and their family members using an application that measures blood pressure and heart rate with cameras and fingerprints . Surprisingly, these people "believe in " the results that the application offers.

It was only when the TD proved that the blood pressure app was given . the watch strap, were the patients convinced that blood pressure measurements with cameras or fingerprints were deceptive. Basically because human phones are not enough "magic".

Not only hospitals, patients . but this app also has over 1 million downloads, rating 4.6 *.

Watch strap has blood pressure, heart rate, blood viscosity index ???What a miracle!

Not only has the application been leaked, but also the review is done.

To know why this type of application is deceptive, learn a little bit about the principle of blood pressure measurement and what it takes to be able to measure blood pressure accurately.

Principle of measuring blood pressure.

The basic sphygmomanometer includes 1 gas pump, 1 pressure gauge, and 1 airbag. Blood pressure unit is mmHg (millimeter of mercury).

For mercury sphygmomanometer and meter blood pressure meter, a stethoscope is required when performing a blood pressure measurement operation. When measuring blood pressure, the cuff is wrapped around the arm and inflated up to a pressure that can prevent blood flow in the main artery (arm artery) through the arm.

After that, the pressure in the air sac and the artery decreases, when the pressure decreases, the person performing the measurement will listen with a stethoscope just above the artery in the elbow, the pressure that the person who first measured the hearing is systolic blood pressure, when the pressure of the cuff is reduced further, the pressure at which the condenser is the diastolic blood pressure and the principle of operation of the sphygmomanometer is indirect measurement of fluctuations in blood pressure.

Currently there are 3 commonly used types of sphygmomanometers: mercury sphygmomanometer, clock blood pressure meter and electronic sphygmomanometer.

A survey by Johns Hopkins University in 2016 showed that for every 5 people with hypertension use phone applications, the results are normal, while measured by specialized medical equipment, 4 people have higher blood pressure than normal.

So, warn your loved ones, when you see a problem, you need to go to a hospital or other reputable facilities for medical examination. Do not wear health for applications on smartphones.
