Read our article on pulse oximeters to learn more about oximeters and oximeter software.

The CMS 50DL is FDA approved (FDA K Number is K082641) and has received CE marking.

The CMS 50DL pulse oximeter is an accurate instrument for checking pulse rate and the saturation of peripheral oxygen (SpO2) in the blood. In healthy adults the resting heart rate is usually in the 50s, and the SpO2 is around 96%. The CMS 50DL features a bright, easy-to-read display to show the pulse rate, oxygen saturation percentage.

The CMS 50DL pulse oximeter is a basic fingertip pulse oximeter that is perfect for CPAP users who want to monitor their pulse and oxygen saturation periodically during the night or day. While not as useful for sleep studies as higher-end models with recording capability, the CMS 50DL is still an excellent and affordable tool for spot-checking two vital health indicators. The CMS 50DL pulseox can be used for up to 30 hours continuously, which is equivalent to about 2500 spot checks before needing battery replacement.

What's the key difference between the CMS-50DL and the next model up?
The CMS-50DL is a high quality, FDA-approved pulse oximeter, and is the best deal in the under-$50 category. The primary difference between the CMS-50DL featured here and the 50D model is that the 50D pulseox has a color, multi-direction OLED screen which shows pulse waveform.

What's the key difference between the CMS50DL and the next model down?
There is not a "next model down". The 50DL is the most basic oximeter we sell. With that said, the 50DL shares the same great performance and 2-year warranty with the rest of the CMS50 pulseox models.

What else is the CMS 50DL pulse oximeter good for?
The CMS 50DL pulse oximeter is great for CPAP users, climbers, skiers, pilots, and for general home health care. It's a low-cost, high-value medical device designed to help you manage your health.

I've seen fingertip pulse oximeters that cost a lot more, but that don't have the features of the CMS 50DL. What's the deal?
We've seen those same expensive oximeters! In fact we've seen fingertip oximeters from certain manufacturers that retail for nearly $400 that offer the exact same functionality as the 50DL. Those manufacturers can't differentiate based on performance, so they tend to focus on durability and drop-testing instead. If you plan on dropping your pulse oximeter repeatedly - over and over again without any restraint at all - then you might want to consider the $400 units. Otherwise, you'll get the exact same performance with the less expensive units like the 50DL. The bottom line is that our pulse oximeters are packed with features and are among the most reliable pulse oximeters in the industry. They're backed by a 2-year warranty.

I've heard the term PulseOx or Pulse Ox before. Is a PulseOx or Pulse Ox the same as a pulse oximeter?
Yes, the terms PulseOx and Pulse Ox are abbreviations for pulse oximeter.
