Yuwell Fingertip Pulse Oximeter YX302

The Yuwell YX302 is a fingertip pulse oximeter that measures blood oxygen saturation (SpO2) and pulse rate in seconds. It's a non-invasive, painless reading — clip it onto your fingertip and the integrated display shows oxygen saturation, pulse rate, and a pulse waveform. The gravity-sense feature auto-rotates the display so the reading is right-way-up no matter how you're holding it.

Key Features

• SpO2 and pulse rate display in a single integrated reading.
• Pulse strength and pulse waveform — visual confirmation that the reading is reliable.
• Gravity-sense auto-rotating display reads correctly from any angle.
• Low-power consumption for extended battery life from two AAA cells.
• Compact, single-button operation — clip on and read.
• Painless, non-invasive measurement using calibrated infrared light.

Who it's for

Anyone managing a chronic respiratory condition (COPD, asthma, sleep apnoea) at home, recovering from a respiratory illness, monitoring post-COVID lung function, or living at altitude. Also widely used by clinicians and first-aiders for rapid SpO2 assessment. Look for medical-grade certification (this is) — consumer-only oximeters from non-medical brands often don't meet ISO accuracy standards.

Frequently Asked Questions

What's a normal SpO2 reading?
For healthy adults at sea level, 95-100% SpO2 is the typical range. Below 92% is generally considered worth discussing with a clinician; below 88% in someone with a respiratory condition is often the threshold for supplemental oxygen.

Why does the reading sometimes seem inaccurate?
Painted nails, cold fingers, poor circulation, motion, and bright ambient light can all affect readings. Sit still for 30 seconds, warm your hands, remove nail polish from the test finger, and shield the device from direct light.

Does it work for children?
The standard sensor is sized for adult fingers. For children under 5 or smaller fingers, use a paediatric-specific oximeter or place the sensor on a toe.
