Good to know before you buy

Pulse oximeter readings can be less accurate with cold hands, movement, nail polish or false nails, and for some people with darker skin. Keep your hand still and warm for the steadiest readings.

Do not rely on a pulse oximeter reading alone. If you feel unwell or have concerns about your breathing or sleep, talk to a qualified healthcare professional.

Smart KidsO2™ does not replace care from your child's doctor. Follow their advice for any condition your child has.

Questions

Questions people ask before buying

More answers in our Product FAQs.

What ages is Smart KidsO2™ for?

Children aged 3 to 10.

Where does it go?

On a finger or a toe. The thumb usually reads best, and the index finger works if the thumb is too tight.

How will I know if a reading is out of range?

The device vibrates when oxygen drops below your limit. The LOOKEE® App on a paired phone sounds an alarm for low oxygen and for a pulse that is too low or too high. The device does not vibrate for pulse.

Is it a medical diagnosis tool?

No. It helps you keep an eye on readings at home. Talk to your child's doctor about any health concern.

What if it is not for us?

You have 30 days to send it back, a 1-year warranty, and lifetime LOOKEE® tech support. See our return policy.
