I have a health question and was wondering if you'd know the answer. I went to sleep with a pulse oximeter on because I have been having forceful breathing episodes in my sleep through my nose, sometimes waking me up and I have concerns about sleep apnea as I found out that I have most of the symptoms. I had myself monitored during a short part of the time. The episodes seem to be averaging about 15 or so an hour with occurances of them sometimes 2 or 3 in a row. At the time right before the first episode, the oximeter read 93 (for the oxygen) / 75 (for the pulse) and as the breathing spell began, it went to reading 93 (oxygen) / 79 (pulse) to 92 (oxygen / 81 (pulse) going all the way up to 92 (oxygen / 112 (pulse) and then as the breathing spells stopped changing to 94 (oxygen / 111 (pulse) and going down to 94 (oxygen) / 81 (pulse) within a total of one minute. The lowest it went before another episode began was 93 (oxygen) / 71 (pulse). The second occurance began within 1 1/2 minutes after the first. This same rapid pulse readings occured after alot of the episodes I had with my pulse ranging from 60 to 70's before the event and my pulse going up past the 100 range during or right after the event. My question is what the oxygen level and pulse would drop to during sleep apnea / and if the rate of going from 95 or 94 down to 92 is low enough to be apnea. I do know that the rapid pulse could be indicative of the apnea but I do not know about the oxygen level. I am having surgery this Monday and am very concerned about doing so with this possible problem. I would like to know prior to the surgury, if possible. Thanks. ps.. I am also coughing, clearing my throat, and congested through my nose in my sleep waking up with headaches, not coughing through the day though and just have a mild stuffy nose. The problem seems to me to be within my nasal passage as the forceful breathing is also coming from my nose.
