SoftPap Available '''pressure support is variable ''' in each SoftPap level, 1, 2 & 3, increases as pressure goes up. This can be confusing, and is best explained visually , with another chart. Gotta love charts.Remember that '''PrismaSmart ''' only has access to the first '''levels 1 & 2 levels ''' of softpap. '''Prisma20a ''' and above to '''all 3 level 3 softpap, which is really Lowenstein'''s Tri-level modeof Softpap.

You can see that as cpap pressure is increased, the size of each level of pressure support increases at set intervals. '''8cmH2o''' and '''12cmH2o''' are key pressures when this happens. You can have a situation where your IPAP is increased by double that of your EPAP. You can also maintain constant EPAP, whilst auto apap increases your IPAP pressure like this below.
