Test Setup
Use the airway port for ventilator testing. Use a
test lung to set up a test that measures ventilator
parameters in bi-directional or uni-directional
modes. Fluke Biomedical recommends the bi-
directional mode.
Bi-directional Flow Mode
For bi-directional flow connections, see Figure 5.
1. Use a Y-piece adapter to connect the
ventilator to the flow inlet on the Analyzer.
2. Use a standard breathing hose to connect to
the exhaust port on the Analyzer.
The Analyzer shows the flow of gas
delivered by the ventilator.
