Re: Active PEEP
Our system currently displays peak pressure, but because of the way we display the arrival at peep, you can actually see that as well. By sending values out to the serial port, we can make it easy for

Re: Active PEEP
YES! I'm working my way through Erich's fantastic documentation and so far haven't seen anything about pressure graphing. I was going to wait until I finished reading the document to say anything in

Re: Active PEEP
This is the expiratory valve. We are just using it to control Peep. I don¡¯t know about the usage, we are certainly using it many more cycles this way!! But we have well over 1.5 million cycles on

Re: Active PEEP
