CMS-50E Pulse Oximeter

The CMS50E Fingertip Pulse Oximeter is an FDA-approved device for spot-checking blood oxygen saturation levels and pulse rate. The CMS50E’s padded finger chamber comfortably fits any finger size and delivers a swift reading. This portable device uses a rechargeable battery that provides up to 20 hours of power when fully charged. A single button located on the front of the oximeter controls all operations. This pulse oximeter was made for ease of use by physicians, nurses, patients, athletes, and pilots.

The CMS50E pulse oximeter uses a small but powerful measurement system. The device accurately measures oxygen saturation (Sp02) and pulse rate directly from any finger. This blood oxygen sensor detects low oxygen levels in the blood, even when the wearer is not actively interacting with the device. The oximeter does not require any external wires or probes when taking measurements.

This oximeter’s compact and lightweight design makes it ideal for travel or storage in a small space. Detailed SpO2 and pulse rate measurement information displays on the bright, multicolored screen with sharp text and images. Measurements update on the device’s screen as a numeric value, bar graph, and waveform animation. These data visualizations present a model of the wearer’s blood oxygen levels and pulse rate for helping the user understand the results. Screen brightness is adjustable to allow for use in a wide variety of lighting conditions.



Auditory and visual alarms in the device alert the user when oxygen levels in the blood go outside the user’s upper/lower range. Additional alarm types include low voltage level and improper device placement alerts. The optional pulse sound setting indicates the wearer’s current pulse rate.

Unlike most finger oxygen sensors, the CMS50E features a rechargeable lithium-ion battery that users can charge via USB or the included power adapter. A battery icon indicator provides a charge status level for the device’s rechargeable battery. For power-saving, an auto shut-down feature turns the device off within five seconds of finger removal.

The CMS50E can store up to 24 hours worth of information data history on the built-in storage. With the included software, users can transfer the data to a computer for exporting, saving, or sharing results with a medical professional or physician. The included data transfer cable connects the pulse oximeter to a PC for software integration.
