5.3.1.2 Precautions for Use of Flow Sensor Pressure Sampling
Pipeline Test Fixture
There are two connectors for pressure sampling lines on the flow sensor pressure sampling pipeline
test fixture, as shown below.
FIGURE 5-14
The connector for pressure sampling line can be connected with Ø6 silicone tubes. When using the
flow sensor pressure sampling pipeline test fixture, remove the expiratory or inspiratory flow sensor
from the breathing system first. Then mount the flow sensor pressure sampling pipeline test fixture
onto the position where the expiratory or inspiratory flow sensor was originally mounted and tighten
the Inspiration/Expiration Connector Coupling, as shown below. Perform test after connecting the Ø6
silicone tube to the connector for pressure sampling line.
