Wlx 501 Pulse Oximeter

Uses of Wlx 501 Pulse Oximeter

Used to non-invasively measure blood oxygen saturation (SpO2) and pulse rate; helpful for home monitoring in respiratory illness (e.g., asthma/COPD), COVID/flu recovery, high altitude exposure, and general fitness/health checks.

• •Measures SpO2
• •Measures pulse rate
• •Helps monitor hypoxia risk at home
• •Quick and non-invasive reading
• •Useful for respiratory illness monitoring

How it works

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.

Directions for use

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.

Side effects

Common side effects of Wlx 501 Pulse Oximeter may include:

• •No known side effects; may cause brief fingertip pressure/discomfort in sensitive users

Warnings & precautions

This is a screening/monitoring device and does not replace medical evaluation. Readings may be inaccurate with poor circulation, cold extremities, low blood pressure, movement/shivering, dark nail polish/artificial nails, bright light, anemia, carbon monoxide poisoning, methemoglobinemia, and in some arrhythmias. Seek urgent care if SpO2 is persistently low or symptoms (breathlessness, chest pain, bluish lips) occur even with normal readings. Keep out of reach of children; choking hazard if small parts/batteries are accessible.
