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:

monitoring, 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
