My partner has been using the Resmed F10 for just over 3 years, but over the last few months he has developed the habit of sticking his lower lip out from underneath the mask and leaving it there, thus breaking the seal.
When he does this I can physically see him having apnea attacks so I reposition the mask for him.. but it only lasts 30 seconds or so before he does it again.
He can't breathe through his nose due to a deviated septum so mouthguards and chin straps wouldn't help. Any suggestions?
Can't get in to see the sleep clinic due to covid restrictions so I'm at my wits end :(
