Pulse Oximeter

Most of the time when you spend time in a hospital you will have the experience of having a pulse oximeter used on yourself. They have nice quality oximeters and now you can purchase that style for personal use. My youngest son has been having a higher pulse and he's been exercising and losing weight to try and lower his pulse so that he can donate plasma. I think this would be a great product for him to have to keep track on how he is doing.
