Top reasons to get an overnight pulse oximetry study:

  • Find out if you might be at risk for sleep apnea. Sleep apnea tends to display a distinct pattern of oxygen drops while you're asleep. 
  • Find out if your CPAP machine is fully-treating your sleep apnea or if you're still having dangerous oxygen drops while you're sleeping.
  • Find out if you qualify for oxygen therapy. If your oxygen level is <89% for at least 5 minutes, you will qualify for oxygen therapy.

Your rental includes:

  • You may keep the device for up to two nights. Your report will be for one night of data. We give you an extra night in case something comes up and you're unable to do the test the first night. 
  • Full nighttime pulse oximetry report delivered through a secure electronic link. 
  • USPS Priority Mail shipping is included.
  • Should your nighttime oxygen test suggest a high likelihood of sleep apnea, you will receive a $35 credit towards a home sleep apnea test or online sleep doctor consultation to discuss the test's findings. 
  • Are you looking to purchase your own Nonin overnight pulse oximeter device to check your overnight oxygen levels whenever you want? We can help you with that as well! We include all the parts and software that you need to access your data.

Generally speaking, yes. If this will be important to you, always check with your insurer before ordering.

Does this study test me for sleep apnea?

No, this study online tests your nighttime oxygen levels. We do offer an affordable home sleep apnea test

Will my insurance, or anyone else, find out about this study?

No, your results will not be reported to your insurance company or any other party without your express written consent. 

What causes low blood oxygen during sleep?

Common medical disorders that result in low O2 levels while you sleep include: sleep apnea, lung diseases like chronic obstructive pulmonary disease (COPD), emphysema, and chronic bronchitis, heart disease like congestive heart failure (CHF), ALS, myasthenias gravis, pulmonary hypertension, obesity hypoventilation syndrome, sarcoidosis, pulmonary fibrosis, mesothelioma and lung cancer. Living at high altitude is associated with lower oxygen levels while sleeping. 

What symptoms do low oxygen levels while sleeping cause?

Low oxygen levels can cause waking up short of breath, waking up not feeling refreshed, morning headaches, and daytime sleepiness and fatigue. Frequently, people don't have any symptoms but develop medical problems over time due to long-term exposure to low oxygen while sleeping. 

Do I need a prescription or referral to order this oxygen level test?

No, you can order the oxygen level study without a referral or prescription. 

Can this study be used for me to get an oxygen concentrator or oxygen tank?

Yes, if the study is abnormal, a qualified medical provider can use the results to prescribe oxygen therapy for you. 

What do I do if the study is abnormal or if I need help understanding what the results mean?

You have the option of scheduling an online consultation with our doctor or reviewing the results with your personal health care provider. 

What does the test measure?

The test continuously measures your blood oxygen level and heart rate. 

What type of device do you use?

We use the Nonin 3150 which is considered one of the premier devices for this type of testing. 

What what is the normal oxygen level while sleeping?

Oxygen levels ≥ 90% are normal. 

Is it normal for oxygen levels to drop while sleeping?

Slight oxygen level dips are normal during sleep but you should not drop <90%. 

Is this the same as the pulse oximeters that I can buy in the store?

No, those pulse oximeters only "spot check" your blood oxygen levels. They do not measure continuously and record the data. 

What are some common reasons for ordering a nighttime blood oxygen study?

Health care providers commonly order nocturnal pulse oximetry to screen patients for sleep apnea and to assess how well sleep apnea treatment (with CPAP, BiPAP or ASV) is working. The test is also used to diagnose COPD and other chronic lung conditions. It can be used to assess the effectiveness of supplemental oxygen therapy and non-invasive ventilation used for disorders affecting the cardiopulmonary system. 

Is this the same as the devices and apps that measure blood oxygen levels and work with my smartphone (iPhone and Android) such as iHealth and iOximeter?

No, those devices, such as the Oura, Motive, and Wellue, are not FDA-approved to measure continuous pulse oximetry. This means that the measurements they provide may not be entirely accurate. The device that we use is FDA-approved for this use, which is the gold standard for accuracy and reliability in medical testing. 

Can I get treatments from you if my pulse oximetry study is abnormal?

Yes, depending on the pattern of abnormality on your study, a sleep apnea test or supplemental oxygen therapy may be indicated. Singular Sleep provides both of those. 

Are there any additional costs?

We use very expensive medical equipment and are required to place a $75 hold on your credit card to ensure that the equipment is returned to us. The hold will be refunded shortly upon return receipt of the equipment.
