Oxygen Concentration; Calculated Breath Parameters; Excel Add-In - Fluke VT650 User Manual

Oxygen Concentration

The Analyzer measures oxygen concentration
through the airflow channel. An integrated
sensor measures the oxygen percent of the gas
in the airflow channel of the Analyzer. The range
for this sensor is 0 % to 100 %. The oxygen cell
is mounted inside the enclosure on the rear
bulkhead for the high-flow circuit. The oxygen
cell must be replaced approximately once a year
(VT650) or every 2 years (VT900).

Calculated Breath Parameters

From the primary flow and pressure
measurements, the Analyzer calculates breath
parameters. A breath detection algorithm
determines the various phases of a ventilator
breath and calculates the parameters listed in
Table 10.
