Helium use from Internal Reservoir
The internal helium reservoir contains sufficient helium to provide
approximately 36 fill cycles at full capacity. With every Autofill,
helium will be depleted in the following approximate amounts:
Effects of altitude changes during air
transportation
For proper operation during air transport, IABP
balloon pressure must adapt to local atmospheric
pressure. The system will automatically purge
and fill the IAB when local atmospheric pressure
decreases by 25mmHg or increases by 50mmHg.
These pressure changes occur approximately
every 1,000 feet (305 meters) of increase in altitude
or 2000 feet (610 meters) of decrease in altitude.
Autofill Condition
Helium Used
Pump is powered off, powered on, and IAB fill performed
to restart therapy
6 Autofill cycles
IAB disconnected and reconnected and IAB fill performed
to restart therapy
6 Autofill cycles
Autofill performed due to a Gas Gain in IAB Circuit alarm,
IAB Disconnected alarm, or an Autofill Failure alarm
6 Autofill cycles
Autofill every 2 hours
1 Autofill cycle
Autofill every 1000 feet (305 meters) of altitude increase
during ascent
1 Autofill cycle
Autofill every 2000 feet (610 meters) of altitude decrease
during descent
1 Autofill cycle
Note: The supply of helium in the internal helium reservoir will deplete more rapidly when an
autofill is performed when the system is powered on, when the catheter is disconnected and
reconnected or when an autofill is performed due to a gas loss, catheter disconnect, or autofill
failure alarm.
