Scuba divers have always wanted a health device that they can take with them when they go scuba diving in order to monitor their oxygen levels. The reason it is important to do this is actually because they are operating at such depths that oxygen is at a scarcity. As such, it is critically important t ensure that they are getting enough O2 that their body is not at risk of hypoxia. Hypoxia refers to a medical condition that occurs when the body does not get enough O2 in the system and as such the tissue may begin to die. A pulse oximeter is actually a great device that can help monitor this health condition for scuba divers. A pulse oximeter has been around for decades but its use as a portable medical device has only come about as of the past decade.

Now the question is whether a pulse oximeter can actually be used underwater with the diver. The answer to this question is that the person would need to put the device within a contraption that would shield it from water as that would damage the computer. If they are able to shield it from the water then they can actually use it underwater. Divers actually like the device because it is very small and portable and they can take it with them wherever they want without having to worry about the fact that it may become a hassle to transport with them. These pulse oximeter devices were never portable and actually were only found in the hospital settings. But with the advent of new chip technology they were transformed to something completely mobile and that can be taken anywhere that the person desired to go while still monitoring their health to ensure that they are functioning at optimal levels.
