Ramping indicator: Appears if the VPAP is in ramp mode. This disappears once
the ramp time has elapsed.
Set pressure(s): In CPAP mode, this displays the set treatment pressure (units:
centimetres of water). In other modes, it is exhalation and inhalation pressures
(units: centimetres of water).
Trigger indicator: How the VPAP changes the pressure when you are inhaling.
"S" (Spontaneous) indicates a patient triggered change and "T" (Timed) indicates
a device triggered change.
Pressure bar graph: Graphical display of the changing pressure.
Leak: Current mask leak (units: litres per minute).
Respiratory rate: Number of breaths per minute.
Minute ventilation: Volume of air inhaled per minute (units: litres per minute). It
is the product of respiratory rate and tidal volume.
Tidal volume: Volume of air inhaled per breath (units: millilitres per breath).
Cycle indicator: How the VPAP changes the pressure when you are exhaling. "C"
indicates a patient cycled change; "TiMn" and "TiMx" indicates a device cycled
change.
Measured inspiration time: The average inhalation time measured by the
VPAP.
Set IPAP Max: The maximum inhalation time set by your clinician.
Measured I:E ratio: The inhalation to exhalation ratio measured by the VPAP.
