Connection To The Respiratory Apparatus; Standard Trigger Values; Baseflow - Fluke VT305 User Manual

Connection to the Respiratory Apparatus

There are three different methods to connect the Product
to the respiratory apparatus:
•
Downstream of the Y-piece
Fluke VT305
Ventilator
•
In the inspiration duct upstream of the Y-piece
Fluke VT305
Ventilator
•
In the expiration duct upstream of the Y-piece
Test Lung

Standard Trigger Values

Because the Product can measure flow in each direction, it
gyo038.eps
makes sense to use the first connection method. In this
measurement setup, flow is usually chosen as the trigger
value. Flow triggers are stored as standard values in the
device and can be reset when necessary. The standard
Test Lung
trigger values for the flow trigger for adult breathing, for
example, are:
Starttrigger:
Endtrigger:
With the second and third connection methods, pressure is

usually chosen as the trigger signal. In this case the
standard values are as follows:
Starttrigger:
Endtrigger:

Baseflow

The base flow is the constant flow that must be ignored
when you calculate volume. If there is an identified
leakage in the system, like a constant discharge of 3 l/min
