CPAP Machine Choices - read this before you accept a new machine
RE: CPAP Machine Choices - read this before you accept a new machine
@Starfishtmk,

Unfortunately you refused the right machine. If your Central Apnea/CA events were high enough that your doctor recommends ASV, which in most cases is very hard to get them to do this, it signifies your need for an ASV is very very obvious.

The ASV has the backup rate required to treat CA. I suggest calling the DME back and telling them you've changed your mind and want the ResMed AirCurve 10 ASV.

Thank you Dave and Gideon. I called the DME provider today and will go back next week to pick up the ASV  machine. I very much appreciate your explanations. It puzzles me why the medical community seems to be so at odds with their information. Thanks for your help. Have a nice holiday. Thanks

She said the blowing air alone would not force me to breathe when I stop. I have been waiting 10 months with NO MACHINE to get correct one for my new diagnosis. So I refused the Resmed ASV, hoping to research to find what I really need. My doc office was really angry that technician told me that. Doc office said I do not need a backup rate.

You might point it out to the tech and your doc that the AirCurve 10 ASV has BOTH a calculated backup rate AND a default backup rate of 15 BPM (pg 4-5 of the clinical guide)

Quote:ASV  mode

In ASV  mode,  the  expiratory  positive  airway  pressure  (EPAP)  is  fixed  and  can be  manually  adjusted to eliminate obstructive  events.  The Pressure  Support  (PS)  varies  between the Min  PS  and  the Max PS  to  answer  to the patient's  need.  Mandatory  breaths  are delivered at  the patient’s  recent spontaneous  breath rate,  ie,  the timed backup rate is automatically  calculated to  match the patient’s needs  and  is  applied appropriately  in  the  case  of  an  event.

Quote:Backup  rate
The AirCurve 10 ASV device  uses  breath  phase  mapping to provide  a  timed backup  rate that  is  synchronized  with the patient’s  own breathing.  When  the patient  deviates  from  the ventilatory  target,  the  ASV device  aims  to  stabilize  the patient  by  adjusting  Pressure Support.  If  necessary,  it  will  adjust  the timed  backup rate  from  one  that  matches  the patient’s  own recent rate  towards  the built-in default  15  BPM  backup  rate.

Wow! Sounds pretty sophisticated. I guess the tech I was dealing with needs a little more schooling in this machine. I can’t imagine where you found this information, Grumpy (I’ll bet you’re not really grumpy) but I am so glad you shared it with me!❤️

It's in the clinical guide for the AirCurve 10 ASV.

It has info you'd want to read.

Request it via the instructions below:

Good luck on this journey,  for some people the ASV takes a while to acclimate.
