Changes

Often when pressure is insufficient, you can see in a Resmed trace, the second hump in the flow rate and/or the fuller second half of inspiration. The example above has pressure set to 6cmH2o and with EPR of 2 (a common minimum pressure new users are sent home with). You can see the obvious instability. This is why with a Resmed machine, the moment you switch on EPR, you are setting a new lower EPAP pressure. Not only that, you will spend a majority of time now at pressures around this lower EPAP pressure and during inspiration some time between the two pressures. A user will spend only a very brief time at peak IPAPpressure. You must take this into consideration. If you are looking to keep EPAP where it was, but increase pressure in inhalation then you would increase main pressures by the same amount as epr setof EPR that you use.

This same principle is not generally needed with SoftPap. SoftPap It behaves in the reverse of Resmed EPR. You will spens spend a majority large amount of time around IPAP pressures and only briefly drop to EPAP. This does affect how each unit must be set and what disordered breathing conditions these two methods favour. You must understanding understand how each tool worksto effectively treat differing conditions.
