The Acc U Rate® CMS 500D Generation 2 Pulse Oximeter is the Deluxe version of our Acc U Rate® line of pulse oximeters. It shows your measured SpO2 and pulse rate on a high quality OLED screen (with six multidirectional display choices) and features an additional plethysmograph that measures your pulse strength.
What is a plethysmograph?
Each wave corresponds to a heartbeat and the amplitude to the amount of blood detected in your blood vessels. For best results, the of the wave amplitude should be consistent throughout as shown in the figure above. If not, you should retake your measurement and make sure that your finger is positioned right under the LED lights and sensor.
Additional Hardware Improvements Made to the Acc U Rate CMS 500D Generation 2
1) Four out of the six multidirectional displays now includes the plethysmograph.
2) Built using high density ABS plastic to block ambient light from reaching the sensor, increasing the signal to background ratio and the accuracy of the measurement dramatically.
3) Uses soft, hypoallergenic medical grade silicon in the finger chamber to ensure comfort to your finger.
4) Uses a self-adjusting spring system to fit your finger snugly into the chamber without impeding blood flow.
Despite the added features, the pulse oximeter remains light and portable, allowing convenient measurement on the go.

I received the CMS 500D Generation 2 as a review sample and used a Concord Emerald Fingertip Pulse Oximeter as a point of comparison. Both devices provided the same pulse and SpO2 readings (taken about 30 seconds apart), so I am satisfied that this is an accurate device.
The biggest difference between this and the comparison model is this one has six display modes, three of which allow you to change display orientation. These include one portrait mode and two landscape modes to view the numbers. You can access those with the press of the button that also serves as the on/off switch. In addition to the SpO2 and pulse readings, there are three additional display modes that show pulse in bar and two types of wave graphs.
My review sample looks slightly different from the one depicted in the product images at the time of this review. Mine has a removable rubber (or silicone) casing that covers the unit entirely. The product description clearly states that it comes with it, but the product photo does not show it. I removed it because I did not see any benefit or purpose other than a level of protection if you are prone to drop things. I am mentioning this so you will not be surprised if you do purchase it and what you receive does not resemble the photo. There is nothing wrong with the configuration that I was provided – in fact, it’s probably better because of the protective cover.
The documentation from an user perspective is light. You are assumed to know how to interpret readings. However, the technical specs and trouble shooting information are in depth and among the best I have seen for these home medical devices.
Bottom line: I prefer this to the pulse oximeter that I had been using because of the display modes. That is a personal preference, but I must say that being able to have the display conform to my finger positioning is better than trying to position my finger to see the results. The graphs are an added plus. This one is definitely worth considering if you are comparing models.
