Do you feel that the Ti time change has made a specific difference?(07-16-2015, 10:52 AM)richb Wrote: You are still getting a lot of leaks. You might want to try a chin strap to eliminate the leaks. The leaks are probably removing too much CO2 and causing the CAs.
Could you explain that a little more. I am having a senior day and am not following why that would be the case.
They are not my leaks. What I was asking is for your logic behind the statement that , "leaks may be washing out CO2".
According to the OP he was having a problem with the transition from exhalation to inhalation not the other way around.
Ti max and Ti min do not control the inspiration pressure time, they set limits for it. Similar to max and min IPAP with an autoset.
The change that the OP made to the Ti max could not possibly have made a difference to the problem he was having with the transition from exhalation to inhalation because the Ti max only operates at the end of inhalation when it is time to transition to exhalation or for the inhalation to exhalation transition.
