•This manual should be completely read, to safely and correct use of the equipment and to
get maximum performance.
•Disconnect the equipment from electrical power source before cleaning.
•Do not expose this equipment to liquids to avoid electrical shock hazards. Do not use the
equipment if the internal components were being exposed to liquids.
Caution
•The Ventilator Analyzer don’t emit electromagnetically waves that interfere in the functioning
of the equipment’s in its proximity.
•The Ventilator Analyzer should be CALIBRATED yearly. All the maintenance service
procedure should be done by trained personnel only.
•Use only parts, pieces, cables and sensors specified and acquired from MAGNAMED. Part
Number in chapter 12.
•Turn on the equipment and proceed to the verification and basic adjustments –follow the
instructions;
•Wait at least 30 minutes to get temperature stabilization in order to have stable pressure and
flow readings.
•Observe the correct connection of the flow sensor and verify that no obstruction is present
inside the sensor.
•Do not expose the equipment to extreme temperatures. To get correct measurements be sure
that the ambient temperature is between 18 and 40 ºC during its use.
•Do not use the equipment if any problem cannot be solved.

•The Ventilator Analyzer has an independent power supply unit. Keep it connected to the
electrical power source to charge the internal batteries.
oPlug the power cord into a three pin, NBR 14136 standard (Chapter 5.2);
oKeep the equipment connected to a power source even when it is turned off so that
the internal batteries are permanently charged.
oRecharge the batteries completely after use or after a long period of storage;
Notes
•Dispose of removed parts in accordance with the institution's parts and parts disposal protocol and
follow local governmental recommendations for environmental protection, especially in the case of
electronic waste or electronic parts (e.g. batteries).
•The technical specifications of MAGNAMED‘s products are subject to change without previous
notice.
•Pressure units:
1 mbar (millibar) = 1 hPa (hectoPascal) = 1,016 cmH2O (centimeters of water)
Practically these units can be used as:
1 mbar = 1 hPa ≈1 cmH2O

3 Description
3.1 Intended Use
The Ventilator Analyzer –VentMeter is an instrument to be used in evaluation and test of lung ventilators.
The measurements are done by flow sensors and pressure sensors.
The flow measurement is bidirectional and is carried out by three kind of flow sensors calibrated to neonatal
to adult range of flows.
The Ventilator Analyzer measures 17 mechanical ventilation parameters, besides measuring the oxygen
concentration of the gas output from the ventilator.
The Ventilator Analyzer can be used to pre-evaluate lung ventilators before its acquisition, as well as for
periodical performance evaluation of the equipment in service and is extremely useful during training courses
to interpret ventilation curves.
Basic Characteristics:
•AC Input 100 ~ 240 VAC –50 ~ 60 Hz;
•Internal battery with intelligent charger;
•LCD Display to show pressure curve, flow curve, volume curve and monitored values;
•FiO2monitoring, maximum pressure, mean pressure, PEEP/CPAP, respiration rate and I: E
Ratio;
•Keys to navigate between many available screens;
•Keys to select monitored parameters to be visualized;
•Allows serial communication to a PC to register all the results
•PulmoTrend software to register all data and to better visualization (basic version available to
download and is free)
3.2 Operating Principles
The ventilation parameters measurements are done by a flow sensor connected proximally to the lung
simulator.
Through this flow sensor the equipment gets the basic readings of:
•Flow
•Pressure
These data are continuously monitored
The other parameters are calculated from these two data:
•Maximum Flow
•Minimum Flow
•Exhaled Volume (Tidal Volume)
•Inspired Volume
•Minute Volume

MAGNAMED Ventilator Analyzer - VentMeter P/N: 1901509 –Rev 05
•Inspiratory Time
•Expiratory Time
•I: E Ratio
•Respiration Frequency (Respiration Rate)
•Maximum Inspiratory Pressure (Peak Inspiratory Pressure)
•PEEP (Positive End Expiratory Pressure)
•Mean Pressure
•Plateau Pressure
•Minimum Pressure
•Static Compliance
•Dynamic Compliance
•Airway Resistance
Beside these monitored data by the flow sensor, it is possible to measure the oxygen concentration of the gas
mixture from the lung ventilator under test (FiO2–Oxygen Inspired Fraction).
The available flow sensors are:
•NEONATAL Sensor –NEO - Flow from 0 to 20 L.min-1
•INFANT Sensor –INF - Flow from 0 to 50 L.min-1
•ADULT Sensor –ADU - Flow from 0 to 150 L.min-1
