CHAPTER 10: PRINCIPLES OF OPERATION
EXTENDED RANGE CONFIGURATION OPERATION SUMMARY AND PNEUMATIC DIAGRAM
Ambient air enters through an inlet filter on the compressor. The compressor pressurizes the air and then delivers
it to the ventilator through a source gas supply hose.
In the ventilator, the gas flows through the safety valve and then to the flow valve, which controls all inspiratory air
flow to the patient. A flow sensor is also provided to measure delivered flow to the patient, and the closed-loop
control system ensures the delivery of the required flow to the patient. A pressure sensor is also used to measure
the pressure at the patient connection to ensure patient safety. The electromechanical pneumatic system also
controls PEEP during exhalation.
See diagram on the following page.
GENERAL OVERVIEW
The Life2000® Ventilation System utilizes an electromechanical pneumatic system under the control of a
microprocessor to deliver patient ventilation. The following descriptions and diagrams illustrate the major
components of the ventilation system in each configuration.
