Restart your mobile device. Then restart the iHealth Wireless Pulse Oximeter by holding down the button for ~ 8 seconds.

Make sure your finger is inserted correctly. Open the clamp of the pulse oximeter, and then place your middle, ring or index finger of your left hand into the rubber opening with your nail side down. With your finger in the correct position, keep perfectly still and test it again.

The battery may be low. Charge the device using the included USB cable.

The iHealth Wireless Pulse Oximeter is not waterproof. Do not immerse the device in water. If it gets wet, wipe it with a dry towel.

We recommend you to clean the oximeter once per week, carefully swabbing inside the device with a soft cloth or cotton swab with rubbing alcohol. Do not pour the alcohol directly on or into the device.

Yes. The pulse oximeter can be used and it will store the data until the next time you sync with your mobile device.

The app can store up to 9,999 measurements.

Yes, simply install the iHealth MyVitals app on every mobile device you are using.

The pulse oximeter uses the iHealth MyVitals app on the Apple App Store or the Google Play Store.

The iHealth Wireless Pulse Oximeter can store up to 100 measurements.

• SpO2 measuring range: 70-99%.
• Average Root Mean Square (ARMS) of SpO2 accuracy: 80%∼99%: ±2%, 70%∼79%:±3%, <70%: no definition.
• Pulse rate measuring range: 30-250bpm.
• Pulse rate accuracy: 30∼99bpm: ±2bpm, 100∼250bpm: ±2%.

* When does the battery light indicator appear in the display? The battery light indicator appears when the battery is low.

Up to 100. New readings will replace old readings if the memory is full.

Cold hands, weak pulse, hand movements, fingernail polish and acrylic nails are some of the most common factors that may affect a reading and cause inaccurate results.

Perfusion Index, or PI, is a relative assessment of the pulse strength at the monitoring site. PI ranges from .01%(very weak pulse strength) to 20%(very strong pulse strength). PI is a relative number and varies between monitoring sites and from patient to patient, as physiologic conditions vary.

The iHealth Pulse Oximeter is designed for spot checks. Currently it does not support continuous measurements.

Cold hands, weak pulse, hand movements, fingernail polish and acrylic nails are some of the most common factors that may affect a reading and cause inaccurate results.

The normal resting pulse rate is between 60 and 100 beats per minute.nnMany factors can influence pulse rate, including but not limited to physical activities, fitness level, emotional state, body weight, medications and body position.

Oxygen saturation (SpO2) is a measurement of how much oxygen your blood is carrying as a percentage of the maximum it could carry. For a healthy individual, the normal SpO2 should be between 96% to 99%. High altitudes and other factors may affect what is considered normal for a given individual.

The iHealth Pulse Oximeter (PO3) measures the amount of oxygen in your blood and your pulse rate. The oximeter works by shining two light beams into the small blood vessels or capillaries of your finger, reflecting the amount of oxygen in the blood and displaying the measurement on the oximeter’s screen. The oxygen saturation (SpO2) is measured as a percentage of full capacity.
