Hi all..I have Af, Hf and sleep apnea I wear an sp02 monitor at night and use a Cpap machine..I had an ablation just over 3 weeks ago and finding my sats are in the low 90s when awake and in the middle of the night they dropped down to 63%..thus my alarm kicks in when below 85% and wakes me up, I am then in Af, Ive spoken to the sleep clinic and they have checked the data on my cpap machine and doesnt believe it is my sleep apnea causing the desaturation, I havent got an appointment until later this week with my heart nurse and was wondering if any one else has these episodes of low sp02?

Sorry Bushy few of us would have the back up to tell to be honest. Not too many here with SA.

Hi, I get about 3 episodes a night of low (< 80) SATs & sometimes there seems to be a correlation with heart rate variations (either just before, or simultaneous, or after). Generally low SATs wake me up, so I note the time - & check the next day on data (ECG & SATs data) that I download to my computer. It would be very handy if there is anyone out there who knows more about low SATs: cause & effect, etc. or someone who can point to a useful website/information.Doesn't seem to be much information of any use (that I have come across so far) on the internet.
