1. Introducció
The CONTEC CMS50M Pulse Oximeter is a compact and easy-to-use device designed for measuring blood oxygen saturation (SpO2) and pulse rate (PR). It displays these values along with a bar graph and pulse strength waveform on a digital LED screen. This device is intended for sports and aviation use only and is not a medical device. It is lightweight and portable, making it convenient for on-the-go use.

2. Informació de seguretat
ADVERTIMENT: Pulse oximeters provide an estimated oxygen saturation level. Certain physical traits, including but not limited to darker skin pigmentation and melanin, may cause the oxygen level estimated value to appear higher than it actually is. Users are strongly recommended to establish a baseline value when healthy and at rest. It is recommended that users consult a licensed healthcare provider or professional on how to interpret user readings based on physical traits or characteristics.
