Newly diagnosed - Was this ASV titration typical?
Hey all, great forum and great people here. I wanted to see if my ASV titration experience was normal or if anyone can relate to it.
Info about me:
Male
Age 33, 140 lbs
Diagnosed with idiopathic (primary) central sleep apnea
Intolerant to CPAP/APAP due to treatment emergent centrals
Didn't try Bi-PAP, went straight from APAP to ASV
My initial sleep study showed 13.5 AHI over 4 hours (25 centrals, 2 obstructive)
I went in for an ASV titration and couldn't make it through the night due to how the machine was behaving. I was under the impression an ASV should breath with you but it didn't seem to work that way with me. What happened is:
The first few breaths I took felt natural and the machine mimicked my normal breathing pattern. Shortly after that however, it kept increasing pressure on inhale and would not go back down on each breath. The way the machine was delivering the breaths felt very forced and unnatural. The breathing rate seemed too short, forcing a breath when I wasn't ready and also delivering too much of a breath on each inhale. I wasn't ready to take a breath, but it kept forcing it. The machine was still delivering a breath when I was already trying to exhale. I had to take the mask off to get a deep, satisfying breath. I tried the "blow back" method, which helped temporarily, but the higher pressure came back.
When I asked the tech about this, she said that the machine was set at the lowest inhale pressure it would go, which was 8. She also said nothing else could be done for comfort and that the machine should be auto-adjusting to my breathing, but it clearly wasn't.
I'm almost positive the machine used during the titration was a ResMed VPAP Adapt Auto.
I wanted to ask and see if anyone could relate to this and see if my sleep study tech was correct. I suppose I'm not sure where to go from here. If this is indeed how an ASV is intended to function, I don't see myself ever getting accustomed to it.
Does anyone relate to this? Does a Bi-PAP behave any differently? Any advice or insight is welcomed.
