Hello Again,
The AHI in my last post was 64.88 and after all I had tried I began to feel that it was time to just go back to basics and try to change some stuff up, so I have been tinkering with my settings a little and I made a little breakthrough.
I do not know why but one night I decided to lower my Humidifier from level 5 to 3, my AHI dropped going from 57.80 to 48.09. As my AHI has a tendency to go high and drop from one night to another, I was not overly hopeful it was due to my changing the level, but the next night I dropped it again to level 2 and my AHI dropped to 27.46. I decided to leave it as level 2 another night, and my AHI went up to 33.24.
The next night I dropped again to level one and my AHI was 38.12, I kept it at level 1 for one more night and had an AHI of 23.51, the lowest reading I have had whilst adjusting the humidification. In hindsight, I wish I had tried one more night at level 1, but I was so happy at the reading I decided to turn off the humification the next night and had a nasty reminder to move slower because my AHI jumped up to 49.92; although some 30 points off my highest readings, it was disappointing to see such a jump.
I decided to leave off the humidification to see what would happen the second night without humidification, I also turned my heated hose down from 27ºC to 25ºC, and I had an AHI of 33.53 but experienced rainout in my Nasal Pillow mask.
Last night was my third night with no humidification and with the heated hose at 25ºC, I have posted the result below. I had rainout again and think I will have to raise the hose temperature back to 27ºC tonight as it's not very pleasant.
I have a telephone consultation tomorrow with my Sleep Technician, and as my results show I am having far more Central than Obstructive events, I feel I am not going to get adequate results with the CPAP I have.
Does anyone have any ideas, advice, questions to ask or things to discuss with them from the results I have posted that I may have missed? I have a list of questions and things to discuss, but it would be good to have other perspectives.
