Sleep study revealed significant snore number - help


#1

My family doctor suggested a home sleep test for me after years of my complaint of being more and more fatigued during the day – needing naps and still not feeling refreshed. I am a female, 37 years old, not overweight. I have very low blood pressure (averaging 95/60) and wonderful cholesterol levels. The home sleep test came back that I have low apnea but SIGNIFICANT snoring levels of 589 snores per hour. Could this be a glitch in the test? Or what could this mean? This seems crazy to me. I am to see a pulmonary specialist next week. My husband does not hear me snore loudly, but occasionally I catch myself softly snoring. What are some possible areas of concern? I asked my family doctor if this number was for real…if maybe the machine had a glitch. Nope. It’s the real deal. It just seems really odd to me. He said its a real condition…?

Good question. A snoring level of 589 snores per hour is not possible, given that our respiration rate (number of inhalation/exhalations) is about 15 or 16 at night while we sleep. Snoring occurs on the inhalation. You might want to ask for a copy of the study results and review them. It might be possible that that number was the total number of snores for the entire sleep study, but with your history, that number would also seem high. That said, it is possible to snore, but not have an apnea or a hypopnea event (diagnosis of sleep apnea is based on counting the number of apneas and hypopneas during the sleep study and dividing by the sleep time during the study - that tells you how many events you have per hour of sleep). Getting clarification on the number of snores is your first step. And you can ask about how many happened while on your back vs not on your back (i.e., prone, left and right). Snoring is likely worse when sleeping on the back. Hope this helps!
