VenTest is intended for use in a laboratory environment. It may only be used outside the
nursing sector. It must not be used directly on patients or devices that are connected to
patients. The measuring instrument VenTest is intendedfor over-the-counter sale.
VenTest is the solution for measurements in the following areas:
•Flow Low (-20 20 L/min)
•Flow High (-300 300 L/min)
•Volume
•Differential pressure
•High pressure
•Ambient pressure
•Oxygen
•Temperature
•Air humidity
•Dew point temperature
In addition, various ventilation parameters can be measured:
•Inspiratory volume, expiratory volume
•Ventilation rate
•I:E
•Inspiratory time, expiratory time
•Ppeak
•Pmean
•Pplateau
•PEEP
•PF Insp (inspiratory peak flow)
•PF Exp (expiratory peak flow)
•Ti/TCycle
•Cstat
•Delta P
VenTest is a measuring instrument for checking and calibrating ventilators and
anaesthetic machines. It must not be used for patient monitoring. During patient
treatment by the ventilator it is not allowed to connect to FlowAnalyser.
This product is intended to be used at elevations of up to 2000 MASL in buildings.

3.1.3. Principle of flow measurement
Flowintheflowchannelisdeterminedbydifferentialpressuremeasurement.Tobuild up
differential pressure a plastic screen is used to provide flow resistance.
ƞ: dynamic viscosity of the gas [Pa s]
ρ: gas density [kg/m3]
c1, c2: device-specific constants
(channel geometry)
Dynamic viscosity
The viscosity of a medium is its resistance to the flow and shear of the current. Viscosity is
extremely dependent on temperature. The viscosity of a medium is slightly dependent on
the pressure and moisture content of the medium.
Density
Density is the unit for the mass per unit volume of the medium. Density is very dependent
on pressure and temperature.
The impact of ambient conditions is hence the reason why flow is occasionally converted to
standard conditions. (3.2 Gas standards for flow and volume measurement)
3.1.4. Special functions
Automatic battery operation in theeventofa power failure.
3.1.5. Communication interfaces
USB, RS-232 port for firmware download, remote control functions and connection to
MultiGasAnalyser OR-703 (optional), trigger input (digital) for external trigger
3.1.6. Physical data

3.1.7. Calibration by user
Offset calibration of the pressure sensors, calibration of the oxygen sensor.
