Wlx 501 Pulse Oximeter — Uses, Dosage & Benefits

A pulse oximeter uses red and infrared light through the fingertip to estimate oxygen saturation (SpO2) based on light absorption differences between oxygenated and deoxygenated hemoglobin. It also detects pulse rate from pulsatile blood flow signals.

Insert 2 AAA batteries if required (as per device), place the device on a clean, warm finger (nail facing up), keep the hand still at heart level, and press the power button. Wait a few seconds for stable readings; avoid movement, cold fingers, nail polish/false nails, and strong ambient light for best accuracy. For personal tracking, record readings at the same time each day or as advised by a clinician.

Always follow your doctor's prescription. Do not self-medicate.
