The Nonin Experience: 13 Years of Pulse Oximetry by Nonin

December 12, 2023

David Teslow has been using Nonin pulse oximetry products for over 13 years. In 2009, David had a health scare that revealed blood clots in his lungs. After this incident, it became a necessity for him to understand and monitor his oxygen levels. David turned to Nonin, purchasing his first Nonin oximeter, a Nonin 9500 Fingertip Pulse Oximeter.

“I have three Nonin oximeters now, and I depend on these things,” David said. “I carry one around my neck all day, I have another by my bed to use at night, and a third one in my family room. I use my oximeters many times a day.”

David is now on supplemental oxygen that he takes with him everywhere. He uses his oximeters to help him make informed decisions regarding his oxygen intake.

“I can usually sense when I’m getting low,” he said. “So, I double check with my oximeter and make a decision based on that. These pulse oximeters are miracle things for me, I’m sure I wouldn’t be alive today without them, they are that crucial.”

When deciding what oximeter to purchase in 2009, David did some research about the available options. He chose Nonin because they were the original inventor of the fingertip pulse oximeter.

“I knew my oximeter would be incredibly important, so I wanted one that was quality,” David said. “I still have my original Nonin 9500, and it still works. If you need an oximeter, you need to look at Nonin.”

David’s original oximeter is indeed still working. Since he’s a local Minneapolis resident, he stops by the corporate office every few years to inquire about replacement springs to keep the clamp working well.

“The people at Nonin have been so kind to me,” David said. “Not only is Nonin the top of the line in producing oximeters, but they are real, kind people, working to help people live better lives.”
