Note on the 2-year warranty and software technical support: the warranty does not cover any problems you may encounter with the included software, including installation problems or usage problems. Because computer configurations differ greatly, sofware compatibility problems may exist on some computer systems. These types of issues are unrelated to the oximeter device and are therefore not covered by the warranty. Please contact the manufacturer directly if you encounter any software-related problems or if you need technical support related to using the software.

The CMS 50F pulse oximeter includes everything you need to connect to your computer to see detailed oximetry reports. You can wear the pulse oximeter all night long with or without your CPAP machine to get detailed oximetry readings. The built-in flash memory will record up to 24 hours of data. Just plug your oximeter into your computer with the included USB cable and you'll be able to create a report with the included software.

The CMS 50F wrist pulse oximeter is a full featured wrist-mounted fingertip pulse oximeter that is perfect for CPAP users who want to monitor their pulse and oxygen saturation periodically during the night. This type of oximeter can help you as a CPAP user determine the effectiveness of your current CPAP pressure. With 24 hours of data storage, rechargable lithium battery, DC power adapter plug, software, USB cable, carrying case, and 24 month warranty, the 50F is a great way to take control of your CPAP therapy and your health.

The CMS 50F wrist pulse oximeter features a color, multi-direction OLED (organic light emitting diode) screen with four levels of brightness. The easy-to-read 256k color OLED display can be adjusted to be readable either horizontally or vertically. The display shows pulse rate, blood oxygen saturation, pulse waveform, pulse bar graph, and battery level indicator. The 50F can sound an alarm in the following scenarios:

  • when the pulse rate or oxygen saturation drops below a pre-set level
  • when the oximeter unit isn't correctly positioned on the finger
  • when the battery level is low

What's the key difference between the CMS-50F and the next model up?
The CMS-50F is the most advanced wrist pulse oximeter available for under $170. There is no next model up in terms of functionality. It's similar to the 50E and 50H models, but the display is worn on the wrist. The fingertip probe connects to the wrist display via a short cord that easily plugs into the wrist display.

What's the key difference between the CMS50F and the next model down?
The CMS50F features a rechargeable, long-life, lithium battery just like the CMS50H. The CMS50F, though, features a comfortable wrist-mounted display that's worn like a wrist watch. The next model down in terms of price is the 50H which is functionally equivalent to the 50F wrist pulse oximeter.

What else is the CMS 50F pulse oximeter good for?
Besides being an exceptional instrument for CPAP users, the CMS 50F wrist pulse oximeter is useful in sleep studies, personal health spot-checking, diabetes management, athletics, primary care treatment, and in situations where the alarm can alert you to hypoxia (e.g. in small, non-pressurized aircraft aviation above 10,000 feet).

I've seen fingertip pulse oximeters that cost a lot more, but that don't have the features of the CMS 50F. 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 functionality of our least expensive, most basic pulse oximeters that retail for around $40. 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.

5 of 5 Much improved March 10, 2014
Reviewer: Anonymous Person  
I purchased one of these about a year ago and another last week.  What a different experience.  The new version is significantly improved - mostly the software.  I loaded it and plugged in the unit and it worked immediately.  Since I had experience previously, I found it very easy to use.  There was NOTHING in the manual about how to use the software which is a huge mistake since the unit is useless without the software.  That being said, it works perfectly.

3 of 5 CMS50F Fingertip Pulse Oximeter with Wrist Display September 28, 2013
Reviewer: Anonymous Person from Elk Grove Village, IL United States  
It arrived fast, but the fingertip appliance didn't match the connection to the Wrist Display.  I called customer service and they were quick and helpful to attend to my concerns.  I sent the package back and am awaiting it's replacement.  Unfortunately, I have to wait for their next shipment from China.  My rating is three stars.  It is an average of the one star I gave because the product parts were incompatible and five stars I gave for the quality of customer service received when I called about the issue.

4 of 5 Wrist Pulse Oximeter June 18, 2013
Reviewer: Anonymous Person  
I bought this wrist instrument one year ago to spot check my CPAP by making overnight recordings.  The computer reports are excellent, and give the statistics on the two most important data in a sleep study (O2 & Pulse).  The report is a mini-sleep study.

There were two problems with this wrist instrument were: 1) The wrist band was too large on the smallest setting.  I had to re-sew the band to make it smaller.  2) The electrical connector between the finger cup and the read-out was too weak, and the signal could be lost if the connector was touched.  To solve these problems, I have ordered a new CMS50E that has no wrist band, and no connector.
