56 Operating the Device
EPAP
(only point 2 BILEVEL ST20/25 in modes BILEVEL S, T and ST)
Selection of expiration pressure (EPAP) by the physician
1. First set IPAP.
2.
Use the selection keys and to set the desired value. Confirm your setting
by pressing the enter key .
The parameter I-Slope is set next.
I-Slope
(only point 2 BILEVEL ST20/25 in modes BILEVEL S, T and ST)
The I-Slope determines the time of pressure increase from EPAP to IPAP.
• Level 1 = 10 hPa/s
• Level 2 = 20 hPa/s
• Level 3 = 40 hPa/s
Selection of I-Slope by the physician
1. First set IPAP and EPAP
2.
Use the selection keys and to set the desired value. Confirm your setting
by pressing the enter key .
The parameter E-Slope is set next.
Calculation of the I-Slope time:
Settings:
IPAP = 10 hPa I-Slope = 2 Frequency = 12 bpm
EPAP = 6 hPa E-Slope = 2
I-Slope Time =
IPAP – EPAP
I-Slope
I-Slope Time =
10 hPa – 6 hPa
20 hPa/s
= 0.2 s
