Yuwell Finger Pulse Oximeter (SpO₂) (Model YX102)

This is a compact fingertip pulse oximeter designed for non-invasive spot-check measurement of blood oxygen saturation (SpO₂) and pulse rate. The packaging identifies the product as a Yuwell model YX102, manufactured by Jiangsu Yuyue Medical Equipment & Supply Co., Ltd. (Yuwell), China.

What it measures

1. SpO₂ (oxygen saturation)The percentage of oxygen-carrying hemoglobin in the blood.
2. Pulse rateHeart rate in beats per minute (BPM).

Physical design

1. Form factorSmall clamshell-style device that clips onto a fingertip.
2. ColorWhite.
3. DisplayThe front of the box shows a digital display with large SpO₂ and pulse readings (the actual display is not visible in the provided photo of the device itself).
4. OperationInsert a finger, allow the device to close gently, and wait for the reading to stabilize.

Regulatory & environmental markings visible on the box

CE 0123	European conformity marking with notified body number.

Typical use cases

1. Home monitoringSpot-checking oxygen saturation and pulse.
2. Respiratory illness monitoringOften used by patients under medical guidance during respiratory illnesses.
3. Fitness/recovery trackingSome users check pulse and oxygen levels after exercise or at altitude.

How to use

1. Insert a clean, warm fingertip fully into the sensor.
2. Keep the hand still at heart level if possible.
3. Wait a few seconds for the reading to stabilize.
4. Read the SpO₂ and pulse values.

Important limitations

1. Readings can be affected by poor circulation, cold hands, movement, nail polish, artificial nails, or bright ambient light.
2. A fingertip pulse oximeter is not a substitute for professional medical evaluation.
3. If you have symptoms such as shortness of breath, chest pain, or persistent low oxygen readings, seek medical advice promptly.
