parameters
Scaling the waveform
axes
Scale the vertical and horizontal waveform axes with the scale buttons.
The vertical scale button autoscales the Y axes to best fit the current
data.
The horizontal (time adjust) button rescales the X axis to show 3, 6,
12, or 24 seconds.

Parameter Definition
Patient data window
Breath phase/trigger indicator Spont (spontaneous): Inspiratory phase, patient-triggered breath (color: turquoise)
Timed: Inspiratory phase, ventilator-triggered breath (color: orange)
Exhale: Expiratory phase (color: blue)
PIP Peak inspiratory pressure. The highest patient pressure during the previous breath cycle.
Pt. Leak Estimated patient leak or unintentional leak. Average during the previous breath cycle. Dis-
played only after a suitable exhalation port and mask/patient interface are selected.
Pt. Trig Patient-triggered breaths, as a percentage of total breaths over the last 15 minutes.
Rate Respiratory rate or total breathing frequency. Moving average over the last 6 breaths (or
15 seconds).
T
I
/T
TOT
Inspiratory duty cycle or inspiration time divided by total cycle time. Moving average over the
last 8 breaths.
Tot.Leak Estimated total leak. Average during the previous breath cycle. Displayed before a suitable
exhalation port and mask/patient interface are selected.
V
E
Estimated minute ventilation. The product of tidal volume (spontaneous and timed) and rate
(spontaneous and timed). Moving average over the last 6 breaths.
V
T
Estimated exhaled tidal volume. Moving average over the last 6 breaths. It is body tempera-
ture pressure saturated (BTPS) compensated.
Waveform window
P waveform Airway pressure. Where applicable, dotted lines represent target IPAP and EPAP.
V waveform
Estimated patient flow. The total delivered flow minus the leak flow (Tot.Leak), where Tot.Leak
includes known (intentional) leakage through the exhalation port plus any unintentional leak-
age in the circuit or at the mask/patient interface.
V waveform Estimated patient volume. In AVAPS mode, the dotted line represents target volume.
