Summary Graph: (OF GREAT INTEREST TO ME)
The Central showed two lines at the beginning of my sleep period and no other centrals throughout the night. I've been having trouble falling asleep since last March, I haven't been breathing at sleep onset and have been waking up. Only Ambien has gotten me to fall asleep.
The two lines were under 30 seconds, first line of graph showed a central of around 15 seconds, second line of perhaps 20-25 seconds............I was first told that I had sleep apnea in July 07 (wasn't aware of any trouble before then) by a woman I slept with as she noted that I had been gasping, choking, not breathing at sleep onset. She was medically trained, she said i had the signs of sleep apnea.....
Obstructive showed up right at same time as centrals, there were three lines close to same period as centrals, each under 30 seconds but between 15 and 25 seconds, followed quickly by four more lines, two of which lasted just over 30 seconds and then three more lines, each under 30 seconds...............................There was only one large cluster of obstructive events, these were about two hours later (between 1 to 2 AM) followed by one solitary line between 4 and 5 AM and a three line cluster between 5 and 6 AM.........
Two Hypopneas around 11:30 PM, both of which were inbetween the Obstructive cluster of that time, then a large cluster of Hypopneas between 1 and 2 AM, these began during the latter part of the Obstructive events of that time and these Hypopneas kept going after the Obstructives ended. Then another cluster of Hypopneas between 4 and 5 AM (the single Obstructive event was in between the occurance of the Hypopneas, it started as a cluster of Hypopneas, the Hypopneas ended then I had the one Obstructive event followed by one Hypopnea event and then the chart shows two single Hyponeas between 5 and 6 AM, first Hypopnea taking place just before the single obstructive event.
Pressure originally was at 6, it went up to 8, went over 10 (to around 11) during 1-2 AM events, stayed around 13 till around 3:30 AM (was woken around that time, in fact I did stay awake at one period around then for over an hour, used ambien to get back to sleep). Pressure dipped at 3:30 AM to around 6 went back up to 12 , showed dips between back to 6 and back up to chart to 12 or 14? during period between 4:30 and 5:30 but I had been awake between 4:30 to after 5 AM.........Chart shows I went back to N2 after 5AM and that pressure stayed steady around 12 or 14 during this period (I was being titrated while on my back at that time).
No Mixed events, no Autonomic events.........Sp02% (oxygen?) was mostly just under 100 but with a few dips to under 90% until the 1-2 AM period where there was a large cluster of lines dropping to low 90's or right at 90% and a good sized number of lines falling under the 90% level. After that, lines stayed in the mid 90's but with several dips under 90 during the latter Hypopnea events between 4 and 5 AM.
