"Highly effective recordable pulse oximeter. I have 10 of these LOOKEE Oxygen Monitors and use them for titration purposes for my dental oral appliance used to treat Obstructive Sleep Apnea. It lets me know how my appliance is helping improve airway metrics as the lower jaw is advanced compared to their baseline test. Its very small and easy to use for my patients. They bring it in and i download the data on the LOOKEE app and print it out for their chart. I send the final pulse ox report to their Dr to show my results."

“I love the design and the ease of use of LOOKEE Ring oximeters. As a sleep physician, I am so thrilled to have such a device available to help us to provide diagnostic and follow-up data to ensure patient’s sleep disordered breathing condition has been adequately addressed. I have also tried it myself and it is quite comfortable and really easy to operate. As a patient and as a sleep physician, I would highly recommend LOOKEE Ring oximeters to other sleep medicine providers as well as to patients.”

"I treat patients with sleep apnea with oral appliances. I have sleep apnea myself. One night I tested Lookee Monitor myself with the appliance. I did great. My oxygen levels hardly ever dropped. The next night, I tested it myself without the appliances. The Lookee device told me that my oxygen dropped many times during the night. In addition, the next day I was tired and grumpy. It was great to document how well it works. It just told me how important it is to keep your oxygen levels up. So I highly recommend Lookee Monitor to track your CPAP or Apnea treatment."

Frequently Asked Questions

View All FAQs

The LOOKEE® Device is designed as an essential component of CPAP treatment and not as a replacement for CPAP in managing sleep apnea. CPAP lacks the oximetry functionality that the LOOKEE® Device provides.

LOOKEE Sleep Oxygen Monitors have earned certification as Medical grade devices and are licensed by Health Canada. These monitors boast an accuracy level of +2/-2%, a performance metric well within the established standard of the FDA for FDA-cleared oximeters.

An O2 Score represents a comprehensive evaluation of your oxygen condition. It is derived from the analysis of various factors such as events, frequencies, depth, and duration of your oxygen levels throughout the night. The score falls within a range of 0 to 10, where 10 indicates the most favorable condition. This score is available for each recorded session within the App.

The scoring categories are as follows:

  • 1-4: Critical
  • 5-6: Low
  • 7-8: Good
  • 9-10: Excellent

Importantly, the O2 Score is calculated from the moment the device is worn until it is removed, encompassing the entire duration of usage.

Normal oxygen saturation levels typically range between 95% and 100% in healthy individuals. Values below 90% may indicate hypoxemia, which means there is a lower than normal level of oxygen in the blood. Generally, an oxygen saturation level of 90% and above is considered safe for most people, especially in non-emergency situations. Additionally, individuals living at high altitudes might experience slightly lower baseline oxygen saturation due to decreased oxygen pressure in the air. However, it's not uncommon for certain individuals, particularly those with COPD, to exhibit slightly lower oxygen saturation levels. Their baseline oxygen saturation usually ranges from 88% to 92%, but this range is generally acceptable for most individuals at rest.

It's important to note that the LOOKEE® Device is non-invasive and boasts a high accuracy of +2/-2, which is remarkable for an oximeter. With this high accuracy, a reading of 88% can be considered within the range of 86% to 90%. It can be confidently stated that the threshold for safe oxygen saturation is around 88%. Readings above this level are safe, while readings below indicate hypoxemia. However, when oxygen saturation drops to 80%, the situation becomes critical. At this point, the lungs may no longer effectively support themselves, causing the heart to beat faster in an attempt to meet oxygen demands. Prolonged exposure to such conditions can lead to cardiovascular complications and increased morbidity over time.

Literally a Life Saver
"This device may quite literally be a life saver. As a nurse, I long suspected my husband had obstructive sleep apnea but I couldn’t convince him he needed to get checked out. I purchased this device and when he saw his O2 sats dropping to dangerous levels and his heart rate spiking, I’m proud to say it only took a couple nights of data to get him to agree to see a sleep doctor. Thank you so much for putting this technology into regular people’s hands!"

A Life-Saving Purchase
"Great purchase has saved my life! I bought this while awaiting a CPAP for sleep apnea. I feel like it has saved my life waking me up when my O2 Saturation dropped too low. My doctor recommended this product. I will continue using it even when I receive my CPAP. My O2 Saturation was dropping to 61% when the normal is anywhere between 95-100%.You can set this to vibrate and wake you up at preset perception and also set the vibration rate as well. Money well spent."

Impressive Tracking Capabilities
"Compared readings with respiratory therapist's pulse ox and was identical. Very helpful to monitor your level of O2 saturation. Even the therapist was impressed with the app and tracking capabilities. CPAP machines don't have O2 monitoring capabilities, so this is a very helpful adjunct."
