ESO 2 ICU Ventilator 16 User Manual
Description
3.2.9.2 Volume Mode
WARNING
Important: Delivering high fresh gas flows when using closed
endotracheal suction.
This ventilator is configured to deliver flows of oxygen in excess
of the maximum shown on the flowmeter tube in order to fill the
ventilator bellows during closed endotracheal suction. Up to
approximately 30 L/min can be delivered.
Delivering O2 flows in excess of the maximum calibrated flow
will temporarily negate the possibility of accurate volume
delivery and measurement. Once the ventilator bellows is full
the O2 flow should be reduced to that in range of the calibrated
flow tube, then accurate volume delivery and measurement will
resume.
See section 5.3 for additional information.
Volume mode
The ventilator delivers a mandatory set volume of gas at
preset, fixed breath intervals.
The patient is making no respiratory effort.
3.2.9.3 Fresh Gas Compensation
The delivered volume is adjusted by up to 60%.
This delivered volume will consist of the volume delivered
from the ventilator bellows, plus the fresh gas flow from the
anaesthetic machine fresh gas supply, minus any compliance
loss and minus any leak.
This gives a total actual inspired tidal volume.
An alarm is triggered if the measured volume is 50% above or
below the set volume.
This function is user adjustable.
Compliance Compensation: Refer to section 3.2.8.2
Altitude Compensation: Refer to section 3.2.8.3
