Response time to Flow limitations
Relative to Resmed Airsense 11 Autoset Elite in Auto mode
Asking for a friend....
How quickly does the pressure increase when a flow limitation is observed?
(I assume that the amount the pressure increases is a function of degree of Flow limitation - but please correct me if that is incorrect)
RE: Response time to Flow limitations
In's not only a matter of "response time", I presume. See
https://patents.google.com/patent/US20110203588A1/en for all details.
RE: Response time to Flow limitations
Here is a statement that may be interpreted and used more easily than that very helpful patent info.
Source of the fragment from a large table:
Treatment of sleep-disordered breathing with positive airway pressure devices: technology update - PMC (nih.gov).
I have no particular qualifications or expertise with respect to the apnea/cpap/sleep related content of my posts beyond my own user experiences and what I've learned from others on this site. Each of us bears the burden of evaluating the validity and applicability of what we read here before acting on it.
Of my 3 once-needed, helpful, and adjunctive devices I have listed, only the accelerometer remains operative (but now idle). My second CMS50I died, too, of old age and the so-so Dreem 2 needs head-positioning band repair--if, indeed, Dreem even supports use of it now.
RE: Response time to Flow limitations
response setting would probably be a factor as well

RE: Response time to Flow limitations
I believe there are multiple factors including severity of flow limitation, quantity/duration of flow limited breaths, algorithm (Autoset or Autoset for Her), response setting (standard or soft), and current pressure (pressure increases are more aggressive up to 12 cm and then less aggressively after that).
As as side note the Elite model is fixed pressure so I have assumed you mean Autoset (without Elite after it).
