ACCESSING THE SETTINGS OF THE DEVICE

The GoodKnight 425 device detects the respiratory cycles of the patient and, in response to its
inspiratory and expiratory efforts, delivers two positive pressure levels, a high level of inspiratory
pressure IPAP and a low level of expiratory pressure EPAP.
If the inspiratory pressure level IPAP is equal to the expiratory pressure level EPAP, then the
device generates a continuous positive pressure during all the respiratory cycle.
The GoodKnight 425 device operates without Back-Up rate, whereas the GoodKnight 425 ST
device can operate with or without Back-Up rate.
The settings parameters are accessible, either directly on the device, or via the computer by using
the SilverLining software.
WARNING
Before setting the device, check that it delivers an airflow when it is in operation mode (see
chapter titled "Use" in the patient manual). In the opposite, stop it immediately and contact
the relevant technical department, listed at the beginning of the manual.

Definitions

Positive Inspiratory Pressure level (IPAP=Inspiratory Positive Airway Pressure) :
High pressure level for the inspiration.
Positive Expiratory Pressure level (EPAP=Expiratory Positive Airway Pressure) :
Low pressure level for the expiration.
Ramp time:
Period of time over which the pressure gradually increases from the starting ramp pressure
to the reference pressure levels with ramp activation.
Starting ramp pressure:
Pressure level at the start of ramp.
Session:
Period during which the data are recorded in the device memory between start-up and
standby. During a session, all the data are collected and displayed in a storage block (the
data cannot be displayed for a session part). A session is recorded if the device is on for 15
minutes without breaking off or after ramp time.
I/E ratio:
Ratio between the inspiratory time and the expiratory time.
Back-Up rate (on the GoodKnight 425 ST device only):
The Back-Up rate corresponds to the respiratory cycle which will be provided when the
device does not detect the patient respiratory cycle or when the patient spontaneous
breathing is lower than the prescribed Back-Up rate.
