I have worked as a Respiratory Therapist for some time now and a good portable pulse oximeter is very important. I would highly recommend any nonin oximeter since they are durable and more accurate. I have another oximeter at home that I've had for over a year and with constant use it is still in great shape, it even has a feature that indicates the strength of the signal. I will check it and post the model once I am back home later tonight.

Just a few tips on getting an accurate reading with your oximeter:

-Make sure that the finger you use the oximeter on does not have nailpolish.
-Make sure the digit you are using is warm. Cold fingers can result in an inaccurate reading.
-With many small home oximeters, the reading is no longer dependable when the subjects blood oxygen is below 85%
-Most individuals should have an oximeter rating of greater than 90%
The device I have used for some time that works well is the Heal Force Prince-100C and it would be a good alternative to a Nonin.
Google your request and a number of companies will appear and you can order online.
