Electronic Ventilator electronics

Sensors and electromechanical components are located inside the unit. The DC/DC power board, 

CPU board and back-up processor, are concealed behind the unit. 
The components and CPU board are connected to each other via a connection board and a cable. The 

sensors have their own amplifier boards and the valves are connected directly to the connectors and 

the board. A single cable connects the units to the CPU board.
All the electronic components are Electromagnetic Interference (EMI) protected inside a shielded 

frame.
Data on driving parameters, patient circuit pressures, Auto/Man. switch position, delivered tidal 

volume, used supply of driving gas and some alarms are sent to the ADU central electronics.
The control unit communicates with the ADU central electronics via a serial communication line.
The ventilator CPU board concealed behind the unit, consists of the power/current limiting circuits. 

Components inside the unit is power limited to below 10 VA because of safety requirements. All 

power limited driving signals are directed via flat cable from the ventilator CPU board to a ventilator 

connection board.

DC/DC power board

The DC/DC power board, generates supply voltages for the CPU board and for the pressure sensor 

boards; +5 V for digital circuits and 

±

15 V for analogue circuits.

DC/DC power board

CPU board

The CPU controls the functions of the electronically controlled Ventilator. It controls the inspiratory, 

expiratory and other valves, reads the pressure and flow signals from the transducers, sends the 

information to the main CPU and receives commands from it through a serial interface.
The processor is a DS80C230, an Intel 51-derivative circuit, accompanied by external RAM for 

runtime data, external EPROM for software storage and a serial EEPROM for calibration data.
The reset circuit includes power-up reset, supply voltage monitoring and watchdog circuit. The reset 

signal always causes the outputs to go into off state.

Valve drivers

There are two kind of valve drivers, proportional and on/off -type.
In a proportional valve driver the current setting is analogous, so the current can be set anywhere 

between zero and max. setting.
The on/off valve drivers are MOS-FET types where the load is connected between the output and the 

ground.
