He has been a faithful user of CPAP for almost 10 yrs now. Pressures are 14/19 on an auto cpap machine made by RESmart. I bought it brand new from someone selling it locally about 2 yrs ago as his Respironics machine was intermittently cutting off. It came with the provider instructions and I set it up (like I've done in the past) after VERY careful research to be sure I was doing it correctly.
For the last 3-4 months he has been waking up at about 6am totally exhausted, headaches, dizziness (feels like he's falling to the left), brain fog (feels like cobwebs in his head and he just can't clear them) and he sometimes forgets things. He then has to take a 2-3 hour nap about 2-3 hours after he wakes up.
He went to the Dr, had a brain MRI 2 wks ago (came back normal) and found he has an abnormal EKG (3rd time since 2009). His primary dr thought he had a recent heart attack.
So we went to a different cardiologist at Duke this past week. He told us there is absolutely NOTHING wrong with his heart! Two yrs ago in 2014 he had a stress test, holter monitor and cardiac catheterization and everything came out fine! At that time they wanted to do MORE tests and I said NO! Enough is enough. He went thru the same thing back in 2009 (except for the cardiac catheterization) and they found nothing! The Duke Dr. advised my husband to keep the EKG with him especially if we travel out of state and he has to go to a hospital because if he has to get another EKG they will "misdiagnose" him again. The abnormality on my husband's EKG is just "normal" for him.
So my next thought (and so was the Duke Dr's) was to get an updated sleep study.
But I just looked at his sleep machine this morning to be sure the pressures were still correct... and they are. I also found an SD card in the back that I did not remember. So I downloaded the iCodes and input his info on BMC's iCode website and generated the following report below.
Day Count 182 90 60 30 7
Days of Therapy % 98% 97% 95% 90% 86%
Avg Daily Compliance 7:18 7:24 7:30 7:30 7:18
Avg P95 (cmH20) 19 19 19 19 19
Avg AHI 2 2 2 2 3
Do you think things look ok, except for the last week? I thought an average AHI of 2-3 was acceptable. I don't know why his numbers are decreasing if he uses his machine every night. Would the daily naps be throwing the numbers off a little?
So I'm wondering... does he really need another sleep study or not? I think it's probably a good idea because it's probably been about 6 yrs since he had once last. So I guess we need to just do it to double-check and rule out one more thing.
Sorry for the long post... any suggestions would be GREAT appreciated!
