Apple Watch credited with saving lives through medical alerts.

An Ohio man credits his Apple Watch with saving his life after the device alerted him to elevated respiratory rate and falling blood oxygen levels. After visiting outpatient care and receiving bronchitis medicine, he received another alert and went to the emergency room, where doctors discovered blood clots all over his lungs. The man was prescribed blood thinners and is now feeling much better. This marks one of the first times the blood oxygen feature of the Apple Watch has been used for something like this.
