A paid applications in Smartphone declared dangerous by scientists. The application failed to measure blood pressure accurately and provide more risk in hypertensive patients.
The study, conducted by Dr. Timothy Plante of Johns Hopkins University, Baltimore, measure the accuracy of blood pressure measurements through the application of artificial AuraLife Instant Blood Pressure. As a result, four out of five hypertensive patients received normal measurement results, which can make them be in danger.
"Hypertension is known as the silent killer and is often asymptomatic. If hypertensive patients got their measurements wrong at risk of serious complications such as heart disease, kidney or stroke," said Plante, quoted by Reuters.
The study was conducted to 85 people with most of them with hypertension. Their blood pressure was measured two times a day using apps and compared with the results of blood pressure using traditional means.
12.4 mmHd found differences in systolic blood pressure (top) and 10.1 mmHg for diastolic blood pressure (bottom). Applications also tend to excessive low blood measurements, and measurement of the lower high blood pressure.
Dr. Beverly Green from Group Health Researcg Institute, Seattle, said the blood pressure is difficult to measure with the help of an application without gripping the upper arm cuff. The cuff is useful to put pressure on the arteries and produce accurate measurements.
"The function of the cuff is pressing the arteries so that the blood pressure used the heart to pump blood and pressure during the heart is at rest can be measured properly," he explained.
Ryan Archdeacon, CEO and co-founder AuraLife selling Instant Blood Pressure, said applications sold by the company is not a medical device. So that the result can not be a reference to diagnose the disease, including hypertension.
"Instant blood pressure can not measure blood pressure greater than 158 mmHg for systolic pressure and 99 mmHf for diastolic pressure. This application is designed to determine the blood pressure at rest and not as a diagnostic tool," he said.
