I see listings for vpap ST machines (e.g. Aircurve 10 ST), but "no longer available". It seems like spontaneous/timed vpap would be the best of both worlds(?) Is there some issue with that technology, or am I not looking in the right places ???

Re: Are "ST" machines obsolete?
Why do you say that?
Where are you looking?am I not looking in the right places ???
Freeze this moment a little bit longer.
Make each sensation a little bit stronger.
Experience slips away.

Re: Are "ST" machines obsolete?
These are the changes between the versions - you can still get all of them if you can find a vendor with stock.
Operating pressure range
S, ST, T: 3 to 25 cm H2O (3 to 25 hPa)
VAuto: 4 to 25 cm H2O (4 to 25 hPa)
CPAP: 4 to 20 cm H2O (4 to 20 hPa)
Supplemental oxygen
Maximum flow: For VAuto device: 4 L/min (CPAP, S, VAuto)
For S device: 4L/min (CPAP, S)
For ST device: 15 L/min (CPAP, S, ST, T)
The ST and T are actually ventilators and aren't availible for general use and were always in short supply.

Rubicon, I was looking at the CPAP dot com website, and a few of their competitors. There was no price listed, and a note "unavailable". But apparently demand exceeds supply (?)
For someone whose breathing rate slows down occasionally (central?) that seems useful. Sleep doc here considers "excursions" into slow breathing and sub-90% O2 sat is "acceptable". I disagree.
Robbob2112, thank you !! That is useful information, clarifies it a lot.

Re: Are "ST" machines obsolete?
The ASV machine works by tracting minute vent (breaths per minute multiplied by volume of exhale for a 90 second average. The upshot is it will track breathing and volume and if you are behind it will force a breath to fill in. This is why it works for central apnea as well as obstructive. Pretty much the only thing to treat central and complex apnea.
It costs a pretty penny more than the base model for the exact same hardware with different firmware.
