But that same day, the man received another alert on his Apple Watch: his blood oxygen levels were dropping. With these results, he went to the emergency room. Computed tomography revealed the root cause of the man’s symptoms: It turned out he had a blood clot in his lungs.
The patient was prescribed blood thinners and “feels much better”. The man believes the Apple Watch saved his life.
