8. Segurtasun informazio garrantzitsua
OHARRA: Pulse oximeters provide an estimated oxygen saturation level. Research and safety communications indicate that certain physical traits, such as darker skin pigmentation and melanin, may cause the estimated oxygen level to appear higher than the actual value. Users are strongly recommended to establish a baseline value when healthy and at rest. It is advised to consult a licensed healthcare provider or professional on how to interpret user readings based on individual physical traits or characteristics.
This device is intended for sports and aviation use only and is not a medical device. It is not intended for continuous monitoring.
