Autoset T will not auto adjust above 10cm

Posted by JEB on June 10, 2001 at 10:01:42:

In an attempt at overcoming problems associated with CPAP (titrated at 20cm), I have been using the Autoset T with a min of 12 and max at 20. I am not using a humidifier and I am using an ultra mirage mask and all settings are correct, however the pressure does not seem to vary significatly from the minimum setting. Any minor pressure increases seem to have just as much to do with leaks as it does with Apneas or Hypopneas. Then I found the following note buried in the appendix of the manual and in the software help file.

"AutoSet T does not differentiate between a closed airway apnea (obstructive apnea) and an open airway apnea (central apnea). For this reason, AutoSet T will not increase pressure in response to apneas once pressure has reached 10 cmH2O."

With this statement in mind it seems that the Autoset T will not auto adjust with settings over the 10cm limit. I would apprieciate any feedback from anyone who has more information on this question. I also have the data file on the last 30 days which I could email to anyone who also has the software and is interested.
