If the Cartridge Alarm is continuous
and air bubbles are rising into the
VSS-1 bubble trap or if a flow or
water is visible in the tube below
the cartridge, then the cartridge
has failed.
If cartridge alarm is intermittent
and there are no bubbles in the
VSS-1 bubble trap or no obvious
water flow below the cartridge there
may be condensation in the system.
First disconnect the patient from the unit,
shut down unit, drain unit, disinfect unit,
replace cartridge, VSS-1 and delivery tube,
and follow set up instructions.
Occasional brief alarms due to
condensation are not a cause for concern.
Try briefly pinching and releasing tube
under cartridge to dislodge the drops and/
or decrease set temperature.
Cartridge
Malfunction of Temperature
Control System.
Shut down system and return for service.
NOTE:
A momentary High Temperature
alarm may occur when the unit has
been switched off and on again. If the
temperature then stabilizes, no action
is needed.
High
Temperature
Alarm
High water or air pressure due to
high resistance in water circulation
or air outlet: or malfunctioning
pressure sensor.
Blocked tube alarm due to high
WATER pressure will cause a
continuous or intermittent tone
and alarm light. The flow of
breathing gas continues, but is
no longer heated.
Blocked tube alarm due to high
GAS pressure will cause a 5 second
alarm tone. If the obstruction
persists the system will continue
to alarm in 5 sec episodes. Water
circulation continues but the heater
shuts off.
Check that delivery tube is correctly
positioned, rotated clockwise, and pulled
into locked position. Check that water is
circulating within delivery tube. If alarm
persists replace delivery tube and/or
cartridge. Disinfect unit prior to replacing
components.
Find and correct the cause of obstruction.
The most common cause is a kink in the
nasal cannual or in the prong. Attempting
to run the Vapotherm 2000i at very high
flow through a patient interface not
approved by Vapotherm may also raise the
internal pressure sufficiently to trigger a
Blocked Tube Alarm.
