Product Information
Q: What is a pulse oximeter?
A: A pulse oximeter is a non-invasive device that measures blood oxygen saturation (SpO₂) and pulse rate. It clips onto your fingertip and provides instant readings.
Q: How accurate is the Reloive pulse oximeter?
A: Our devices feature clinical-grade accuracy:
* SpO₂ Measurement: 70%-100% (±2%)
* Pulse Rate: 30-250 BPM (±2 BPM)
* Perfusion Index: 0%-20%
Q: Is the Reloive pulse oximeter FDA registered?
A: Yes, all Reloive devices are FDA-registered for wellness and sports/aviation use. They are designed to meet medical-grade standards.
Q: What’s the difference between consumer and medical-grade oximeters?
A: Medical-grade devices (like ours) undergo stricter quality control, offer higher accuracy (±2% vs ±4%), and are FDA-registered.
How to Use
Q: How do I use the pulse oximeter?
A: 1. Insert 2 AAA batteries (included)
2. Press the power button
3. Clip the device onto your index or middle finger
4. Keep your hand still and at heart level
5. Wait 10-15 seconds for stable reading
6. Read SpO₂ and pulse rate on the OLED display
Q: Can I use it during exercise?
A: For accurate readings, we recommend measuring at rest. Movement can cause inaccurate readings. If measuring post-exercise, wait 2-3 minutes for your heart rate to stabilize.
Q: Which finger should I use?
A: Index or middle finger works best. Ensure the finger is clean, warm, and free of nail polish.
Q: Why is my reading fluctuating?
A: Common causes:
* Cold hands (warm them first)
* Nail polish or artificial nails (remove before use)
* Hand movement (keep still)
* Poor circulation
* Low battery
Normal Readings
Q: What is a normal SpO₂ reading?
A: For healthy individuals at sea level:
* 95%-100%: Normal
* 91%-94%: Mild hypoxemia (consult doctor)
* Below 90%: Severe hypoxemia (seek immediate medical attention)
Q: What is a normal pulse rate?
A: For adults at rest:
* 60-100 BPM: Normal
* Below 60 BPM: Bradycardia (common in athletes)
* Above 100 BPM: Tachycardia
Q: When should I seek medical help?
A: Contact a healthcare provider if:
* SpO₂ consistently below 95%
* You experience shortness of breath
* Chest pain or dizziness
* Bluish lips or face
For emergencies, call 911 immediately.
