Dräger Primus Instructions For Use Manual page 40

Getting started
System compliance
Primus determines the current
compliance of the patient system with
fitters, hoses and a Y-piece. Depending
on the breathing hoses used, the
inspiratory system compliance is approx.
1.2 mL/mbar.
Leakage
Leakages are tested in the mechanical
subsystem and in the complete system
(see gas diagrams),
Leakage Leak test in the
(system): mechanical ventilation
branch
Indication of the leakage
value in mL/min and
red/yellow/green test
result indicator
Leakage Leak test in the
(Man. Spont.): complete system
Indication of leakages
>150 mL/min in mL/min
and red/yellow/green
test result indicator
Primus determines the current leakage
of the breathing system and breathing
hoses. The system tolerates leakage of
up to 150 mL/min.
For leaks of more than 150 mL/min:
@ Check the components of the
breathing system,
repair any leaks and
repeat the leak test.
Possible causes of leaks include:
— Damaged breathing hoses
— 02 sensor not connected or
incorrectly connected
— Sample line for gas measurement not
connected
— Water trap not inserted
— Breathing bag/diaphragm defective
— Vaporiser not connected correctly/
filling device open
— Absorber nat firmly screwed into
place
— Flow sensor not firmly screwed into
place
— Breathing system not assembied and
fitted correctly
— Microbial filters not connected
securely
