Changes

===Prisma Smart & Prisma20A SoftPAP Compared to Resmed EPR===There is quite a difference in the so called "comfort" settings of the various CPAP & APAP machines. These comfort Lowenstein '''Prisma Smart''' & '''Prisma20A''' provide these settings, are in fact as a limited versions form of regular '''Bi-level''' modes found on higher bi-level machines. These bi-level modes allow a more sophisticated pressure range for addressing more complicated respiration needs.

'''Bi-level''' is the application of more than 1 pressure level during different breathing stages. The example below shows bi-level therapy in action. This is whilst using Softpap2 infact not on a Prisma20A"Bi-level" machine, at but a set Prisma20A with CPAP pressure of 12cmH2oand Softpap2 activated. The machine is now applying 2 different pressures. The lower pressure of '''EPAP''' (exhalation positive airway pressure) and the higher pressure of '''IPAP''' (inhalation positive airway pressure). The difference between these two pressures is termed pressure support, abreviated normally to '''PS'''. The example below shows a PS of 3cmH2o. This is the maximum PS available on a '''Prisma Smart''' and delivers the same support as Resmeds EPR 3, although as you will see, the differing air delivery of the two devices, affects how this pressure support shapes your breathing.
