Sure, junior looks fine sleeping on the baby-cam, but do you know her or his oxygen level, heartbeat and breathing rate, you monster? Of course not (don't worry, you're a good parent), because there's no way of monitoring such things short of hooking the poor tyke up to a pulse oxymeter. At least, until now. Philips has revealed a camera that can detect all those things from afar, without touching the patient. The fruit of the companies contactless monitoring project, it can get a pulse rate, breathing rate and blood oxygen level by detecting changes in skin color that are invisible to the naked eye.
