Bluetooth pulse oximeter CMS50EW-PED is a deluxe model with many outstanding and useful features and suitable for many applications. Furthermore, the oximeter is reliable and accurate. CMS50EW-PED is for both personal and medical facilities, such as hospitals, medical laboratories, and doctor's offices.

CMS50EW-PED comes with a pediatric probe along with an integrated sensor. Use the pediatric probe for small children and the integrated sensor for adults and bigger kids.

Another key feature of CMS50EW-PED is the built-in alarm for the pulse rate and SpO2. If any reading falls outside the defined range, the alarm would sound so one can take appropriate actions. The ranges are specified in the system configuration menu. One customer uses the CMS50EW-PED to monitor his child's SpO2 level while sleeping.

CMS50EW-PED comes with software for managing your data. The data can be transferred to your computer using either an USB cable or Bluetooth connection. Transfer is simple. Connected the CMS50EW to your computer, only a few clicks are needed to see the report on your computer screen. Data can also be captured real-time1. Use the Bluetooth wireless connection if you do not want to have a wire connected to the computer. This is probably true if you are using CMS50EW during exercise or in a sleep apnea study.

CMS50EW probe usage

To use Bluetooth, your computer would need a Bluetooth dongle. Many newer computers already have this function embedded.

CMS50EW-PED can store up to 24-hours of data and the data can be transferred to a computer for archive and analysis.

The pulse oximeter CMS50EW-PED has a rechargeable lithium ion battery, which is good for up to 24-hours of continuous usage. The battery can be recharged via an USB port or an AC adapter.
