Apple wins the battle of blood oxygen for watches

Apple Watch hypertension alerts explained
Hypertension is often called “silent killer” because it can strike without symptoms. Left without control, it increases the risk of heart attack, stroke and kidney disease. By adding passive blood pressure monitoring, Apple Watch aims to help millions of people detect early alert signs.
Using its optical cardiac sensor, the watch examines how your blood vessels react to heartbeat over 30 days. If it detects coherent hypertension patterns, you will get a notification. Apple expects the functionality to alert more than a million people with unheeded hypertension during its first year only.

Clinical validation of the Apple Watch hypertension function
Apple has built the new hypertension notification functionality on a basis of health research years. Since the launch of Apple Watch, cardiac health tools such as ECG, the history of AFIB and irregular rhythm notifications have helped users to take problems early. The hypertension notification now extends this mission by attacking one of the most common and dangerous silent conditions.
The feature works in the background during watch hours, analyzing the photopleyysmography (PPG) signals, changes in blood volume under the skin, to detect patterns that suggest high chronic blood pressure. You do not need to calibrate the functionality or take direct readings of blood pressure with the watch. Instead, the device follows the signals over 30 days and sends a notification if signs of hypertension appear.

The results of the study confirm the accuracy of hypertension alerts
Apple has developed algorithm using data of more than 100,000 study participants through various ages, races, body types and health statutes. The company then validated its precision thanks to a clinical hinge study with more than 2,000 participants, which bore Apple Watch alongside a round at home to compare the results.
The validation study has shown that the characteristic has reached a specific rate above 92%, which means that it has minimized false positives. The sensitivity rates were particularly strong for high stadium hypertension, the most serious form of the condition, where the characteristic has identified more than half of the users at risk. This clarification could help prevent cerebral vascular accidents, heart attacks and kidney diseases in those who do not know otherwise that they suffer from hypertension.
Above all, the study confirmed that the functionality was involved in a coherent manner between age groups, sexes, races and skin tones, which makes it reliable for the global user base of Apple. Apple also carried out use tests to refine the integration and the notification language, so that people understand the alerts and the actions to take afterwards.
By passively monitoring and signaling possible signs of hypertension, Apple Watch helps to fill a dangerous gap in the diagnosis. Hypertension often goes unnoticed for years, but now you can be alerted in just a month after wearing the watch.

The expert cardiologist weighed on Apple Watch hypertension alerts
The cardiologist and scientist, Dr. Harlan Krumholz of the University of Yale and the hospital of Yale New Haven, told Cyberguy,
“I am happy to see Apple turn attention to hypertension – the first avoidable cause of heart attack and stroke. Their approach automatically signals the signals that suggest that you can have high blood pressure and encourage you to check it. This is particularly important because so many people remain unmatched. And identify hypertension earlier.
