The most subtle differences in CPAP machines can often mean the difference between being successful with therapy, and being the proud owner of a very expensive paperweight. One of the most widely implemented comfort features on modern CPAP machines is a form of expiratory relief. This is where the pressure delivered by the CPAP machine is reduced in order to reduce the effort for expiration. Despite most manufacturers having some form of this on their machines, the delivery is often slightly different. This impacts how the machine feels to breathe with, and the overall comfort of the machine.
Each manufacturer seems to have their own take on this function. Also, they all seems to have their own name for it; be it C-Flex or A-Flex (Philips Respironics), EPR (ResMed), EZEX (Transcend), SmartFlex (DeVilbiss), Reslex (3B Medical), Z-Breathe (Human Design Medical), EUT (Curative Medical), or softPAP (Weinmann). They all effectively mean the same thing, the machine drops the pressure slightly during expiration.
However, the means by which they do this differ slightly. Points of difference for the different versions include: Whether the expiratory pressure relief is triggered by the patients breath, or is predicted Whether the expiratory relief occurs full-time, or only during the ramp period.

Thanks for the information. I really like the way you express complex topics in lucid way. It really helps me understand it much better way. nasal pillows mask CPAP medical machines
