Hi Jean,
Did your sleep doctor not speak with you? Any good sleep doctor will follow up with you 1-2 weeks after your study to go over the results with you and prescribe a CPAP if that is indicated. Then, they should follow up with you a month after beginning CPAP therapy to see how it is going and annually thereafter, or if you are having problems.
Here is the part of the sleep study that is important.
This lead to an overall apnea-hypopnea index of 16 events per hour, which is moderately elevated. This is slightly worse in the supine position. Additionally there were 170 respiratory event related arousals with a central respiratory disturbance index that was also moderately elevated at 29 events per hour. When the patient was awake and breathing in the room air, the total oxygen saturation was 98%. During sleep it was 87%.
The apnea-hyponea index (AHI) is one of the values to grade the severity of apnea. Here are the values:
5-15 AHI=Mild apnea
15-30 AHI=Moderate apnea
>30 AHI=Severe apnea
Which is why your study says that your AHI of 16 events per hour is moderately elevated. Supine means on your back. Therefore you had apneas/hypopneas in all sleeping positions but they were "slightly worse" on your back.
Central respiratory disturbances are not due to physical blockages, as in Obstructive Sleep Apnea, but are due to your brain forgetting to tell you to breath.
Normal oxygen saturation is 95-99%, your average value when you were awake was 98%. When you were sleeping, the average O2 sat. was 87%. O2 sat. decreases when you are not breathing, for example, during apneas (total obstructions) and hypopneas (partial obstruction).
You are feeling bad for several reasons. Your sleep is disrupted, your oxygen levels are suboptimal when you are asleep. During each apneic event several physiological changes occur that mess with your body including, your blood pressure goes up, your carbon dixode level goes up, your O2 goes down.
I hope I've answered your questions! You will feel better once you get your CPAP! Keep us posted!
