Oximeter

You know that most of the time when you go to the doctor for your checkups, that they stick this little thing on your finger and tell you they are checking your oxygen level. Well, I just found out it is called an oximeter. I also found out that you can get them for home use. I think that is a great idea but it is important to research the Internet and be sure you are getting a good one. I didn't realize there were so many different types and it was very interesting to learn about them. Along with Blood Pressure machines I think it would be a good idea for us to have one in our home too.
