Introduction
The VT Plus HF Gas Flow Analyzer, referred to hereafter as the Analyzer, is a general-
purpose, gas flow analyzer with special modes for testing mechanical patient ventilators.
The Analyzer measures bidirectional flow in both high and low ranges, as well as high-
and low-pressure ranges. Users control the unit using the command system or a special
control mode that uses RT200-style commands. Multiple special-function tests allow
efficient troubleshooting.
The Analyzer can measure either high- or low-flow and pressure, eliminating the need for
gauges and flow meters. It measures 21 ventilator parameters and can display all of them
on one screen. Results can be printed directly from the unit or from Windows-compatible
software on a PC. The Analyzer also has onboard graphing capability and shows the
minimum, maximum, average, and absolute measurement for all parameters.
This manual provides a description of the Analyzer and its applications. It should be used
as a guide when using the instrument to analyze a ventilator and test lung.
Key Features
• Bi-directional flow, low- and high-pressure, volume, and oxygen concentration, and
pressure measurements
• Very high-frequency measurement capability – up to 900 BPM (15 Hz)
• RS232 and printer ports
• Included Windows-compatible graphics software
• Minimum, maximum, average, absolute, and graph for all parameters
• All 21ventilator parameters displayed on one screen simultaneously
• Operation by user-friendly command mode or RT200 command mode
• Operation with a variety of precision test lungs available from Fluke Biomedical to
complete a fully NIST-traceable ventilator test
• Tests the leak rate of a sealed vessel or test lung
• Tests whether a predetermined parameter deviates from limits set by the user
• Useful for pre-purchase evaluations of ventilators, incoming and routine performance
verification, troubleshooting clinical problems, and teaching principles of mechanical
ventilation
Unpacking and Inspection
Use the following checklist when unpacking the Analyzer. There are no special
unpacking instructions, but be careful not to damage the instrument when unpacking it.
• Inspect the shipping carton for damage. If the shipping carton is damaged, carefully
continue unpacking the instrument and note any dents and scratches on the Analyzer.
Save the damaged shipping carton and packing material for the carrier’s inspection.
• If there is no shipping damage, continue removing the Analyzer from the shipping
case. Save the box and packing materials.
Note
This box contains specifically designed inserts to ensure safe shipment of
the Analyzer. Please save these for return of the unit for service or
calibration.
