Appendix D Fault Management
The general philosophy when handling a software detectable fault condition is to still allow a
basic level of treatment to be applied to the patient - with over pressure protection, oxygen
alarms and apnea monitoring (where possible), but inhibiting the higher level features of the
unit (such as BiPhasic modes).
Fault classification
Each fault condition is classified according to the severity ratings (where

means not
available under software control,

means available under software control, and (

) means
may or may not be available depending on other severity rating 3 and 4 conditions, which
may occur individually or simultaneously):
