VT650/VT900Users ManualAnalyzer ConnectionsYou can connect the Analyzer to a ventilator andtest lung in either a bi-directional orunidirectional flow configuration.Airway Flow (Inlet and Exhaust)The outer diameter of the airway port is astandard 22 mm fitting for use with patienthoses. The inner diameter of the airway portaccepts a 15 mm male respiratory fitting for usewith endotracheal tubes, gas sampling adapters,and similar equipment.WCautionTo avoid damage to the Analyzer andavoid adverse affects on the Analyzerperformance: Do not put metal objects intoconnectors.12 Always use the external flow filter onthe main airflow channel inlet. Thishelps reduce turbulence and keepsout small particles that coulddamage the flow sensor. To avoid damage to the sensor,make sure the pressure inside theairway port does not exceed 5 psi. Measure only dry gases with theairway port. Do not use this port tomeasure humidified gases.

Gas Flow AnalyzerTest SetupTest SetupBi-directional Flow ModeUse the airway port for ventilator testing. Use atest lung to set up a test that measures ventilatorparameters in bi-directional or uni-directionalmodes. Fluke Biomedical recommends the bidirectional mode.For bi-directional flow connections, see Figure 5.1. Use a Y-piece adapter to connect theventilator to the flow inlet on the Analyzer.2. Use a standard breathing hose to connect tothe exhaust port on the Analyzer.The Analyzer shows the flow of gasdelivered by the ventilator.ExhaustInletTest LungGAS FLOW ANALYZERVentilatorVT900Inspiratory HoseFLOWINLETFLOWEXHAUST 300 lpm750 ml /min0 TO 10 mbar0.8 TO 10 barULTRALOW FLOWULTRALOW PRESSUREHIGHPRESSURE160 mbarLOWPRESSUREExpiratory HoseFigure 5.

Gas Flow AnalyzerOperationsAirway FlowAirway Temperature and HumidityThe Analyzer has a full-range flow ( 300 lpm),with bi-directional flow measurement. Flowmeasurements are either static flows—nobreath variations, or ventilator waveforms—bothan expiratory phase and an inspiratory phase.The Analyzer uses a heat transfer sensor tomeasure the flow.There is a temperature / humidity sensor in theairway channel on the exhaust side of the flowsensor. The Analyzer uses the temperaturereading to automatically adjust for the gascorrections (see Table 6).Use this measurement for pediatric or adultventilators or to determine the performance ofmany types of flow meters.High PressureAirway PressureThe Analyzer measures airway pressure from aproximal tap of the channel (near the exhaustport).Tap More Data on the Airway screen to seetemperature and humidity.The high-pressure port measures gaugepressure in the range of -0.8 bar to 10 bar. TheAnalyzer can use this pressure measurement forany gauge pressure in the given range.19
VT650/VT900Users ManualLow PressureUltra-Low Flow (VT900)The low-pressure port is a dual-port connectionconsisting of a ( ) positive and a (-) negativepressure port.The Analyzer (VT900 only) has ultra-low flow( 750 ml/min) bi-directional flow measurementcapability. The flow measurement is foraccurate, high resolution, static low flowmeasurements, not for ventilator waveforms.The flow sensor uses the heat transfer methodto measure air flow. Use the ultra-low flow tomeasure many types of low flow meters.The differential pressure range is 160 mbar.Use this pressure measurement for anypressure differential or gauge pressure in thegiven range.Ultra-Low Pressure (VT900)The ultra-low pressure sensor measures gaugepressure in the range of 0 mbar to 10 mbar. Usethis pressure range for accurate, very lowpressure measurements.20Barometric PressureThe Analyzer makes barometric pressuremeasurements. The barometer reads absolutepressures from 8 psia to 18 psia. The Analyzeralso uses the barometer in the automatic gascorrections for airway flow measurements.
Gas Flow AnalyzerOperationsOxygen ConcentrationCalculated Breath ParametersThe Analyzer measures oxygen concentrationthrough the airflow channel. An integratedsensor measures the oxygen percent of the gasin the airflow channel of the Analyzer. The rangefor this sensor is 0 % to 100 %. The oxygen cellis mounted inside the enclosure on the rearbulkhead for the high-flow circuit. The oxygencell must be replaced approximately once a year(VT650) or every 2 years (VT900).From the primary flow and pressuremeasurements, the Analyzer calculates breathparameters. A breath detection algorithmdetermines the various phases of a ventilatorbreath and calculates the parameters listed inTable 10.Excel Add-inInstall custom Excel add-in, available fordownload at www.flukebiomedical.com.
