Figure 6: Treatment screen 4 (only if ResLink and pulse oximeter are attached)
The treatment screens contain the following information:
Treatment mode: Mode of treatment set by your clinician. Options include:
CPAP, Spontaneous, Spontaneous/Timed and Timed.
Ramping indicator: Appears if the VPAP III ST-A 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:
centimeters of water). In other modes, it is exhalation and inhalation pressures
(units: centimeters of water).
Pressure support: The difference between exhalation and inhalation pressures
(units: centimeters of water).
Trigger indicator: How the VPAP III ST-A changes the pressure when you are
inhaling. "S" (Spontaneous) indicates a patient triggered change and "T" (Timed)
indicates a device triggered change.
Cycle indicator: How the VPAP III ST-A changes the pressure when you are
exhaling. "C" indicates a patient cycled change. "T" (Treatment screen 1), and
"TiMn" and "TiMx" (Treatment screen 3) indicate a device cycled change.
Pressure bar graph: Graphical display of the changing pressure.
Leak: Current mask leak (units: liters per minute).
Respiratory rate: Number of breaths per minute.
Minute ventilation: Volume of air inhaled per minute (units: liters per minute).
It is the product of respiratory rate and tidal volume.
Tidal volume: Volume of air inhaled per breath (units: milliliters per breath).
Measured inspiration time: The average inhalation time measured by the
VPAP III ST-A.
Set IPAP Max: The maximum inhalation time set by your clinician.
Measured I:E ratio: The inhalation to exhalation ratio measured by the
VPAP III ST-A.
Oxygen saturation level: Percentage of oxygen in your blood stream (only
appears if ResLink and oximeter are attached).
Pulse rate (HR): Measured in beats per minute (only appears if ResLink and
oximeter are attached).
SpO2: 98%
HR: 75 exit
(This screen only
appears if ResLink™
and oximeter are
attached.)
