patients respectively.
In volume control ventilation mode, the delivered gas
volume is the sum of the setting TV and the amount
of leakage. The leakage compensation in invasive
ventilation: the upper limit of the leakage compensation
is 80% of the setting TV.
In pressure control ventilation mode, the ventilator
regulates the flow automatically to compensate the
leakage in order to maintain the inspiratory pressure.
But the upper limit of the compensation is restricted
by the TV high limit. The ventilator will not increase the
flow and display the [
Volume Limited
] alarm message
when the flow exceeds the TV high limit (If you want to
reach the maximum leakage compensation, you can set
the TV high limit to off).
Automatic leakage compensation
The ventilator determines the difference between the
delivered flow on the inspiration side and the measured
flow on the expiration side.
This difference provides a measure of the amount
of leakage and is displayed by the ventilator as the
leakage minute volume MVleak.
The ventilator can compensate for this leakage in
volume controlled ventilation.
Example:
Tidal volume setting TV = 600mL, 10% leakage in tube.
Without Leakage compensation
The ventilator delivers 600mL. This is indicated as the
inspiratory tidal volume TVi. 60mL escape as leakage
during inspiration, and 540mL reach the lung.
540mL are expired, and 40mL again escape as leakage.
A tidal volume of 500mL is measured on the expiration
side and indicated as TVe.
With a ventilation rate of 10 strokes per minute,
a minute volume of 6.0 L/min is delivered on the
