Doctors not having to manually probe any signs of heart/lung problems each time they're in the room, would mean that they get either get more time to test each patient for consciousness/lucidity; get time to check on more patients; or (my preferred option) are able to make each check-session shorter and less invasive (no need to sit the patient up to listen to their lungs through their back, for example), and thus less disturbing of a patient's sleep quality (because it's easier to go back to sleep after a short conversation, when you haven't had your blood pressure spike from sitting up.)
