could get a new life-saving feature, and one completely unrelated to the heart disorder headlines you may have seen in the past.
Several factors contribute to this, including the one you’d probably guess — using the Apple Watch’s motion sensors to algorithmically separate swimming and a person trying to attract action or in distress.also shows blood oxygenation and heart rate factoring into the equation. An increase in heart rate and a decrease in blood oxygenation clear can be clear signs of a problem in this context.
The patent describes this as a relatively “cost-effective solution” compared to more conventional methods, such as camera-based safety systems that also may not be suitable for all environments, including “natural pools.”
