orsystems thatgenerate gas flows or gas pressures. That includes ventilators and
anaesthetic machines. The user of the device has received training on how to use
medical equipment and can perform repairs, maintenance and servicing on medical
devices. The device can be used in hospitals, in clinics, at device manufacturers or at
independent service companies that perform repairs or servicing on medical devices.
FlowAnalyser 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 FlowAnalyser is intended for
over-the-counter sale.
FlowAnalyser 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, variousventilation 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
FlowAnalyser 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.

4.1.3 Principle of flow measurement
Flow in the flow channel is determinedbydifferential pressure measurement. To build
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
Theviscosity of a medium is its resistance tothe flow and shear
of the current. Viscosity is extremely dependent on temperature. Theviscosity of a
medium isslightly dependent on the pressure andmoisture content of the medium.
Density
Density is the unit for the mass per unit volume of the medium. Density is very de-
pendent on pressure and temperature.
The impact of ambient conditions is hence the reason why flow is occasionally con-
verted to standard conditions.
(4.2 Gas standards for flow and volume measurement)
4.1.4 Special functions
Automatic battery operation in the event of a power failure
4.1.5 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
4.1.6 Physical data
