    Product is fantastic. My son that is about to turn 9 months old has down syndrome and is still on oxygen. We live in Colorado and are set to visit family at lower altitude, looking forward to being able to test him on the go and monitor throughout the night on our own schedule as well as during the long car ride. Only critique I would offer is a more intuitive website to order from, had to search and carefully read for proper accessories. No issues at all though, completely satisfied customer here.

    I am happy with the device, it is working exactly as described and the ability to upload the data to a computer is very useful. I will likely be placing an order for the optional AC adapter in the near future.

    We purchased the unit directly from CMI health and were extremely satisfied with the product and experience. Tina Chen was the CMI Health Team rep who assisted me throughout, and was always professional, timely, and thorough. The product, well…there aren’t too many infant-compatible meters, but this one rates and performs the best. Our daughter had a preemie who was on oxygen because of lung development and altitude. It was scary at first given the unknown, but this device allowed us to routinely monitor oxygen and eventually notify the doctor that the pulmonary study could be administered. There is a feature that allows you to track, download, and document the results. This was critical for the doctor’s determination to move forward and order the study. The form, fit, function, on a preemie was awesome. I highly rate this product.

    Very satisfied with this product. As a home health care nurse it is very useful for patients I visit that do not have a pulse oximeter in their home.

    A year ago I bought the CMI model PC-66H from Amazon web site (for ~190$) with adult finger sensor for use to monitor over night the oxygen level and heart rate of my 93 years old mother in law, it work quite well that we can sleep knowing that if any problem happen to her, the unit will sound the alarm that quite loud that we can hear it from the next room, it actually happened several times which we have to give her oxygen mask. The unit built is quite good quality with long cable for use with 3 different kind of sensors Adult, Pediatric and infant.(the unit come standard with adult sensor).
    Another nice feature is that you can use with 3 AA batteries or an optional power adapter which available at for less than 15$. I am really impress with the quality, features, price point and reliability of the PC-66H which very hard to find unless you want to settle for hospital style unit which cost close to 1000$, BTW, I just bought another one which on sale for 186$ with bonus pediatric sensor from
    One particular thing is the super customer service; I am able to talk directly with Joan and then Tina plus tech support whenever I have any problem and always ending with very good impression.
    In conclusion, I am wholeheartedly recommend the PC-66H from for anyone that have the need to continuous monitor oxygen level and heart rate over night or 24 hours/day.
