Safety Alert – ASV use in CHF Heart Failure Patients
I did not see a thread about this yet, so thought I would post it.


ResMed has recently issued a notice that warns patients about the use of adaptive servo ventilation (ASV). Preliminary data from the SERVE-HF study suggest that there is an increase in cardiovascular death in patients who have symptomatic heart failure with left ventricular ejection fraction of less than 45-percent and are using ASV.

If you are using ASV or similar adaptive servo technology, talk to your doctor about your therapy plan.

This has been discussed in a couple threads on Apnea Board.

If interested but you don't have time to read much else, especially see DocWils comments in this thread:


Topic is also discussed in this thread:
Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment. The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.

I did not see the notification that you had posted on the other thread before I posted this.
I looked for previous threads but musta missed them, sorry about the duplicate post.

I looked at the other thread, and I understand what DocWils was saying. Sadly I fit in that narrow category.

The timing of this was really something. I was just finishing a short trial period with an ASV machine. I saw that it produced an improvement in my sleep quality.

So, with this advisory the sleep doc won't approve an ASV for me, so back to my Bi-Pap.
I will be seeing the dr. this week to see if she will put me on an ST so that I can at least get the benefit of the timed backup to push a breath to prevent the prolonged pauses.
