When reviewing the CMS 50 E, there was a slight learning curve due to all of the available features and the directions written in marginal but understandable English. The main Color display for the CMS 50E was clear and easy to read with contrasting colors; however, the menu display was a little difficult to see due to smaller text. Changing the display angle and brightness was easy. Flash drive memory for the CMS 50 E can store up to 24 hrs. of information. When reviewing the device, it was able to store all information for an 8 hour night. Software included was easy to install and use on a Windows 7 system. Data transfer was simple by both USB cable and wireless. One feature on the computer program allowed the SpO2 and HR to be displayed in real time on the computer display. Reports produced by the CMS 50E displayed all pertinent information such as SpO2 events, averages, and parameters utilized. The alarms were loud enough to wake up by; however, they could not be utilized if data was being recorded which was a drawback. Overall the unit performed well. When compared to other pulse oximeter units that record data, the CMS 50 E was adequate; however, after considering other pulse oximeters with recording capability have a higher average price, the CMS 50E is a good buy for an individual looking for a low cost oximeter with recording capability.

The Nonin Onyx pulse oximeters 9500 v.s 9550
Overall, the Nonin Onyx pulse oximeter product line was found to have the most scientific studies supporting the quality and accuracy of their devices. Although Nonin did not invent pulse oximetery, they were the first company to market self-contained finger pulse oximeters to medical professionals and the general public, in 1995. The first unit produced and still available today, was the Nonin Onyx 9500. Offering a few improvements in the overall design, the Nonin Onyx 9550 was later produced. Both units to date are the only finger pulse oximeters that have passed the U.S Military Airworthiness Certification for use by the military. Upon reviewing the units, both the Onyx 9500 and the Onyx 9550 have similar technology except for the power switch, the onyx 9550 has an automatic shut off which helps conserve battery power giving the 9550 an estimated 21 hours of operation compared to an estimated 18 hours of operation. The enclosed spring on the 9550 vs. the external spring on the 9500 makes it easier to replace batteries. Both displays are simple LED displaying heart rate and SpO2 levels; however, the onyx 9550 has a slightly larger display. Instead of a pleth waveform to help the user determine signal strength, the Onyx series has a simple Red, Yellow, Green light configuration to indicate pulse quality. Overall, the Onyx line is good for individuals expecting heavy clinical use or requiring an extra sturdy finger pulse oximeter.
