New machine vs. Old Machine - Same Model - MrIvanDrago - 10-10-2024
Interesting thing I came across the past few nights with my brand new VAUTO. For the past year I had a ResMed VAUTO 10, bought it barely used from a certified reseller and worked well for a year. I was able to come across a deal to get a brand new VAUTO 10 for 500 US dollars and decided to buy it. I have used it the past three nights with the exact same settings and my Tidal volume in OSCAR has gone up by almost 100, from 460ish to 560ish.
Could the motor in the other machine just gotten worn down? No idea why this is as everything else AHI, RR, etc. has remained the same. Thought I would share and see if anyone had an opinion on why this might happen. The 560 TV is more on target where I should be anyway.

I would suspect two possible areas. First, would be a flow sensor with a low sensitivity. The second is the newer firmware may have an improved calculation. This could be something as simple as changing the leak calculation for a given mask setting.
