1. Bubuka
The CONTEC CMS50M Fingertip Pulse Oximeter is a portable, non-invasive device designed for spot-checking of arterial hemoglobin oxygen saturation (SpO2) and pulse rate (PR) through the finger. It is suitable for use in home environments and for sporting and aviation activities. This device is not intended for continuous monitoring or as a medical device for diagnosis or treatment.
It features a small volume, light weight, and is convenient for carrying. The device displays pulse rate value and a bar graph for easy reading.
