sleep study question

Not sure about this, other than I do not have deep sleep.

Analysis of the sleep architecture revealed that the study extended over 8 hours and 17 minutes, of which the patient spent 6 hours and 15 minutes asleep, producing a low normal sleep efficiency index of 83% of total recording time. latency to Stage N1 sleep was short at 3 minutes and Latency to REM was delayed at 2 hours and 55 minutes. She spent 14% of her sleep in Stage N1, 75% in Stage N2, and 11 % in REM sleep. After sleep onset, there were 50 Stage 1 occurrences, 121 total Stage changes, 31 awakenings, and 2 REM periods scored during the course of the study

I did best with a nasal mask, which I started with per request by the tech. I developed a severe HA and asked to change to my full face. It was during that latter period I did not have good results. It seemed as they raised my pressure, I experienced more events until the pressure was at 15.

Why would I have more events at a higher pressure?
7.5= 4 apneas and 8 hypopneas
10= 5 apneas and 1 hypopnea
12.5= 6 apneas with some upper airway obstruction still noted during REM
Mean duration obstructive apneas was 21 seconds... obstructive hyponeas 28 seconds
Can someone please give me feedback.

They want me to use a nasal mask and I have great difficulty with my sinuses with nasal masks...

Barb, did they have you using cpap the entire time? Or did they start out the night using no cpap (no mask) and come in during the night to put a mask on you?

Barb,
It sounds like you were a "split" night study. 75% of the time the titrations are incomplete. I would talk to your sleep doc and have him consider a full nights titration is that is truly what you need. cpapmasksonlinedotcom

I was on a mask the whole time. The difference was between the first and last sections was the mask. Micro nasal at the start and my Hans Rudolph V2 at the end. Somehow I will get the HR to work.

I think I found a good solution last night and will test it during the next week. This morning I had a 3.0 AHI rating on my EncorePro score!!!! Still had leaks, but not like before. I made a chin strap with a narrow headband to help keep my chin up. Most chinstraps pull on my jaw the wrong way. I did not have a dry mouth this am! I have to sleep on my back, (L1 compression fx), my jaw opens, my cheeks sink in... along with the muscle slackness during REM...=leaks.

Thank you for answering.

Sleep academy guidelines are now suggesting that the Bi-Level titrations now start at 15cm. Might be a good idea to stay with the nasal mask, and ask your dr about a Bipap titration. The change in pressure from inhalation to exhalation may relieve your headache symptoms while still treating the apnea. For example, you would in hale at a pressure of 15, but exhale at a pressure of 8. The change in pressure will make you tolerate the nasal mask better without the continuous pressure at 15cm. Just a thought...
