LEAK xx.xx Lpm
Leak flow calculated from the differential pressure transducer,
measured at the patient wye during exhalation. This value will be
approximately 0.0 when the ventilator is autocycling. Eliminate
autocycling by turning the sensitivity off before reviewing this
measurement.
FTw xx.xx Lpm
or
FTn xx.xx Lpm
Flow in Lpm calculated from the differential pressure measured at the
patient wye. When the value is calculated using the wide scale
differential pressure, FTw is displayed. When the value is calculated
using the narrow scale differential pressure, FTn is displayed.
When Leak Compensation is on, FTw xx.xx and FTn xx.xx Lpm values
are offset by the value of LEAK xx.xx Lpm.

0
Differential pressure as measured across the flow valve.
FV xx.xx Lpm
Flow valve flow in Lpm calculated from the differential pressure
measured across the flow valve.
Transducer count display is not available for this item.
STEP xxxx
Commanded flow valve motor step position.
Transducer count display is not available for this item.
TS xxxx rpm
The monitored speed of the turbine in rpms.
O2 xx.xx PSI
Oxygen inlet pressure in PSIG as measured at the inlet pressure
transducer.
BV xx.xx VOLTS
Internal battery voltage.
EV xx.xx VOLTS
External power voltage.
