Sleep Studies: Findings other than apnea

My nurse practitioner has suggested I have an in-facility sleep study done. Prior to this, I had done some data logging with an inexpensive pulse oximeter for 7 days and never saw oxygen below 95%. My question is: can a sleep study find problems other than sleep apnea?

Thank you for any help.

  1. Hi Lori. My name is Christina. During my Sleep Test in 2015; My test picked up Bradycardia and Paroxysmal Afib ( 2 Heart Conditions). I was sent to an EP Physician @OSUMC; the physician stated it was the Moderate to Severe Sleep Apnea that caused the Arrhythmias. Even though the CPAP Machine was adjusted and treated the Apnea. Im now 52 yrs old. What should I do ?

    1. Hi . It's been a long time since that diagnosis. Have you had a follow-up with a cardiologist since? Sleep apnea can cause both of those issues, but it is important to follow up and make sure they are resolved, especially since you were already using a CPAP at the time. Any doctor should understand your desire for a follow-up and schedule it. If your doctor refuses, it might be time to see someone new. I hope this helps. Keep us updated of you don't mind sharing. I'd like to know how you are doing. Best wishes. - Lori (Team Member)

    2. Christina, thank you. That is helpful.

  2. Hi . Welcome to the community! I am glad you found us. The sleep study they will likely conduct is called polysomnography. It measures brain waves, the oxygen level in your blood, your heart rate and breathing during sleep along with eye and leg movements. Polysomnography can pick up on or at least hint at a variety of sleep issues, so it's a good place to start. Here is an article about the process of diagnosising sleep apnea that might interest you: I hope this helps. Keep us posted if you don't mind. I will be thiking of you. - Lori (Team Member)
