Core components include medical-grade ABS plastic housing, silicone finger insert for comfort, stainless steel spring clip, and a precision infrared sensor module. Display: OLED. Power: typically 2x AAA batteries (batteries may be included or sold separately depending on region). Designed to meet consumer pulse oximeter safety and performance standards.

1. Insert two AAA batteries into the oximeter following the polarity markings.
2. Turn on by pressing the single button; wait for the display to initialize.
3. Place a clean, warm finger (no nail polish) fully into the fingertip chamber.
4. Keep still and wait 5–10 seconds for the SpO2 and pulse rate values to stabilize.
5. Remove finger when finished; unit will auto power-off to save battery.

For best results, avoid motion, cold fingers, or poor circulation. Remove nail polish or artificial nails that can affect readings.

Suitable for adults and older children who need routine blood oxygen monitoring: people with COPD, asthma, bronchitis, or other chronic respiratory conditions; post-COVID recovery monitoring; high-altitude travelers and climbers; pilots and athletes tracking oxygenation during training; caregivers and seniors managing home health. Not intended as a neonatal monitor.

Caution: This fingertip pulse oximeter is intended for spot-check monitoring and is not a substitute for professional medical evaluation or continuous clinical-grade monitoring. Do not rely solely on this device to diagnose or treat medical conditions. Consult a healthcare professional for interpretation of results. Not recommended for infants or neonates. Accuracy may be reduced by poor circulation, cold extremities, movement, dark nail polish, or external light interference.

Storage: Store in a dry place at room temperature. Recommended storage conditions: 0–40°C (32–104°F), relative humidity 15–80%. Remove batteries if storing for extended periods. Keep out of reach of children.
