ESO 2 ICU Ventilator 6 User Manual
3. Description
3.1 ESO 2 System Description
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.

6. Bellows
7. Inspiratory and expiratory hose connectors
8. Inspiratory and Expiratory non-return valves (NRV)
The valves a control the direction of the gas flow through
the system.
Each valve consists of a disc located over a valve seat.
The discs operate by gravity and are retained by guides to
prevent lateral movement.
9. Oxygen monitor sensor
10. Gas delivery On/Off switch
11. Oxygen supply failure indicator
Green indicates OK
Red indicates oxygen supply failure
