Screen 2: Monitoring
1 Pressure bargraph with the set pressure limits.
2 The following therapy parameters are displayed:
Leak, Vt, RR, Ti (refer to Therapy status bar in Treatment screen).
•
Alveolar Ventilation (Va): minute volume without deadspace (Unit: L),
•
displayed in iVAPS mode.
Inspiration to expiration ratio per breath (I:E).
•
2
Pulse oximeter measurements from Nonin: Heart rate and SpO
•
both averaged over four beats of the pulse. Data is only displayed when
an oximeter is connected to the device.
FiO : Average fraction of oxygen level in the air outlet. Displayed when
•
2
an oxygen sensor is connected.
Note: The SpO
diagnostic purposes.
Screen 3: Pressure/Flow
Pressure: Therapy pressure refreshed at 10 Hz (0.1 sec)
Flow: Estimated respiratory flow refreshed at 10 Hz (0.1 sec) (Unit: L/min, L/
sec).
Each graph displays the last 20 seconds of data.
You can scroll back to view past data from the start of the session. Press
then turn it anti-clockwise.
Screen 4: Minute Ventilation/Respiratory Rate
The last five minutes of data averaged over five breaths are displayed.
Screen 4: (iVAPS only) Minute Ventilation/Alveolar Ventilation
The last five minutes of data averaged over five breaths are displayed.
Alveolar Ventilation has a guideline of Target Va.
Screen 5: Leak
Average instantaneous leak: Sampled variably depending on leak change
(Unit: L/min, L/sec).
Pressure/Flow graph: Therapy pressure and estimated respiratory flow
sampled at 10 Hz (0.5 sec).
Each graph displays the last 20 seconds of data.
Screen 6: Tidal Volume
The last 14 breaths of data averaged over five breaths are displayed.
