Airway Flow; Airway Pressure; Airway Temperature And Humidity; High Pressure - Fluke VT650 User Manual

Airway Flow

The Analyzer has a full-range flow (±300 lpm),
with bi-directional flow measurement. Flow
measurements are either static flows—no
breath variations, or ventilator waveforms—both
an expiratory phase and an inspiratory phase.
The Analyzer uses a heat transfer sensor to
measure the flow.
Use this measurement for pediatric or adult
ventilators or to determine the performance of
many types of flow meters.

Airway Pressure

The Analyzer measures airway pressure from a
proximal tap of the channel (near the exhaust
port).

Airway Temperature and Humidity

There is a temperature / humidity sensor in the
airway channel on the exhaust side of the flow
sensor. The Analyzer uses the temperature
reading to automatically adjust for the gas
corrections (see Table 6).
Tap More Data on the Airway screen to see
temperature and humidity.

High Pressure

The high-pressure port measures gauge
pressure in the range of -0.8 bar to 10 bar. The
Analyzer can use this pressure measurement for
any gauge pressure in the given range.
