Introducing the VT PLUS HF
The VT PLUS HF is a general-purpose gas flow analyzer with special modes designed
specifically for testing mechanical patient ventilators. The VT PLUS HF measures bi-
directional flow in both high and low ranges as well as high- and low-pressure ranges.
Other features include:
Oxygen Concentration Measurement. An integrated sensor measures the oxygen
percent of the gas in the high flow channel of the VT PLUS HF .
Breath Parameters. The VT PLUS HF measures 17 parameters on each detected breath.
These parameters include tidal volume, minute volume, inspiratory and expiratory
pressures, lung compliance, etc.
Selectable Units . The VT PLUS HF allows the user to select the desired units for each of
the measured signals. For example, pressures can be displayed in mmHg, kPa, bar, mbar,
atm, inH
2
O, inHg, cmH
2
O or mmHg.
Leak Testing. The VT PLUS HF allows the user to test the leak rate of a sealed vessel or
test lung.
Trend Testing. The VT PLUS HF provides an automated test to see if a predetermined
parameter deviates from limits set by the user.
Evaluations/Troubleshooting. The VT PLUS HF can be used for pre-purchase
evaluations of ventilators, incoming and routine performance verification, and
troubleshooting clinical problems, as well as teaching principles of mechanical
ventilation.
