4 Description 
 
4.1 Operating Principle 
 The Oxymag - Electronic Transport and Emergency Ventilator is a ventilatory support for patients with 
respiratory failure, covering the range of patients from neonatal to adult. The available ventilation modes are 
volume controlled, pressure-controlled and time cycled, and intended for use in patients with tidal volume from 
3 mL. 
 The Oxymag has an oxygen concentration control to be delivered to the patient in the range of 35% to 
100% (depending on the parameter adjustment). The mixture of gases is accomplished through a venturi 
chamber, where ambient air is drawn and mixed with oxygen gas. Its principle of operation can be explained by 
Oxymag block diagram, shown in Figure 1, where the equipment can be divided into two main blocks, 
Electronic Block, composed of PCI and Oxymag Touch Screen Display, and the Pneumatic Block consisting of 
pneumatics and Expiratory Valve. 
 
Electronic Block is responsible for all Human Machine Interface (HMI), where the user can adjust the type of 
patient, ventilation modes, settings and alarms through the Touch-Screen Display buttons. It is also 
responsible for controlling the pneumatic block to effectively establish the parameters previously set. All the 
control of Man-Machine Interface (HMI) and the block is performed by Pneumatic Electronic Control Board 
(PCB Oxymag). Its structure and operation will be detailed in section 4.1.1. 
 
 
Figure 1 – Oxymag block diagram 
 The block is formed by the pneumatic assembly and the expiratory valve. It is composed of valves and 
sensors, together with the electronic control boards that controls the entire gas flow and pressure. The 
 8 
MAGNAMED OxyMag – Emergency and Transport Ventilator P/N: 1600185 
pressure and flow sensors are responsible for sending the information present in the flow and pressure 
transducers to set Pneumatic Electronic Control Board. With this information, the Electronic Control Board 
performs the necessary controls of the current to the valves to control the flow and concentration of oxygen. Its 
structure and operation will be detailed in section 4.1.2. 
 
 
4.1.1 Electronic Description 
 
The electronic board operates according to the diagram below. 
 
 
Figure 2 – Electronic board block diagramDiagrama de blocos da placa eletrônica 
 The electrical power is provided by na external AC/DC converter, it converts 100 – 240 VAC ot 
+12VDC . This tension is enhanced to 13.5V to charge the Li-Ion battery. The led indicates the connection 
to an electrical AC power and it is powered by a 12 VDC, before the ON-OFF switch allowing connection 
indication even if the device is turned off. 
 The battery charger circuit has a dedicated IC with an optimized current control and to switch 
from internal battery to external power supply and vice-versa. The battery charger circuit has an overload 
protection system when the battery discharges to a level below its safety limit, the equipment shuts off 
automatically preserving its integrity. In this case, minutes before, an high priority alarm will be shown.

MAGNAMED OxyMag – Emergency and Transport Ventilator P/N: 1600185 
The battery temperature is monitored by a sensor that interrupts the charging process if the battery 
overheats (above 70C). 
 Even if the device is turned off, the above circuits will be power supplied by the battery an they 
are high efficient and are low power consumption allowing long period lasting for the battery. 
 After the ON-OFF switch, there are DC/DC converter to generate the following voltages: 
 DC Power : Voltage that varies from 9V to 13V depending on the connection to an AC 
power inlet. Power supplies all valves and solenoids. 
 5V Analog: Used to supply voltage to all the analog circuit and to the transducers. 
 3v3: Used to suppy voltage to the IC’s, including the microcontroller. 
 5V Digital: Used to supply voltage to all other IC´s. 
 3v3 VREF: Used as a reference voltage to the A/D and D/A converters. 
 
The OxyMag – MAGNAMED’s Emergency and Transport Ventilator is comprised of: 
 Electronic Control Board – it has two microprocessors to achieve the control of the pneumatic 
system to ventilate lungs and the other to the central command that performs the Human 
Machine Interface (HMI) . 
o Pneumatic control system: 
The penumatic system is comprised of a pressure regulating valve that adequates the 
inlet pressure (O2 cylinder or wall oxygen outlet) to the internal operating pressures. The 
reduced oxygen pressure is applied to the input port of the solenoid valves 
One of the solenoid valves is used to control the overpressure valve. The other two 
solenoid valves are used to zero the flow transducer. To deliver the gas flow in a set 
oxygen concentration there are other two solenoid valves that carry on the mixing of the 
oxygen with the ambient air through a venture system (aspirates ambient air). 
According to the current applied to these valves there is a determined oxygen 
concentration and gas flow. 
These solenoid valves are controlled by high performance digital circuits that reduces 
the electrical power consumption enhancing the efficiency of the battery system. 
There are three diferential pressure transducers to measure the total gas flow, patient 
inspiratory and expiratory flow and the airway pressure. 
Basically the pneumatic control microprocessor receives the commands from the 
adjustment and command central, translates these informations to valves driving timing, 
both flow valves and expiratory valveto control the patient ventilation. 
The signals from the transducers are used in feedback control system of the flow control 
valves and the expiratory valve. The system carries on the measurement of the oxygen 
concentration in the gas flow to the patient. 
Command and adujstment central: 
This central is controlled by a second microprocessor and carries on the data 
acquisition fo the keyboard, touch screen or from the Rotary button to get the 
parameters adjustment desired by the device operator. The results of the adjustments 
and the data received from the pneumatic controller are presented in a liquid crystal 
display as a graph and numerically. 
Once the required adjustments are done they are sent to the pneumatic controller that 
carries on the ventilation determined by the device operator 
During the ventilation process the pneumatic controller sends the main parameters of 
the patient ventilation continuously, such as instant pressure, instant volume, instant 
flow, tidal volume, mean pressure, inspiratory and expiratory time, frequency and other 
parameters. The received data are shown on the display. 
Another function of the command central is to receive the alarm information and put the 
in priority order show them on the display and sound. 
 
 Caution 
 Discharge the battery according to local legislation.

4.1.2 Pneumatic Description 
 
The pneumatic block diagram of the Oxymag is shown in figure 3. 
 The high pressure oxygen (O2) is connected to the pneumatic assembly (maximum pressure 150 PSI 
and the minimum working pressure is 40 PSI). The inlet pressure is reduced through a pressure regulating 
valve ( 1 ) allowing na adequate working pressure, at this point there are a inlet pressure measurement ( 2 ) 
and if the measured pressure is below the minimum required for operating the low pressure alarm is turned on. 
 After the pressure regulator the oxygen is sent to the low flow valve ( 3 ) and to the high flow valve ( 5 ), 
where the gas flow is electronically controlled and its oxygen concentration is measured by a oxygen sensor 
( 9 ). According to the oxygen concentration adjusted by the device operator, the electronic control actuates on 
the low flow valve and through the venturi principle the ambiente air is aspirated through na unidirectional valve 
( 6 ) and is mixed to the oxygen in the venturi chamber ( 7 ). The total flow is monitored by an internal flow 
sensor ( 11 ) and then passes the conical connector ( 12 ). 
 In order to complete the respiratory circuit, the inspiratory limb is connected to the conical connector 
and the expiratory limb to the expiratory valve ( 14 ) the patient proximal side of the respiratory circuit is 
connected to the “Y” piece and then to the proximal flow sensor ( 13 ) that monitor the gas flow to the patient. 
The proximal flow sensor is connected to the pneumatic assembly through the flow sensor lines and internally 
connected to a set of zeroing solenoid valves ( 10 ), that is periodically switched to adjust the offset of the 
measurement. The exhalation cycle of the patient is digitally controlled by the expiratory valve ( 14 ). This valve 
also controls the PEEP (Positive End Expiratory Pressure). 
 In case of a overpressure in the respiratory circuit, the alarm sounds simultaneously to the opening of 
the solenoid valves ( 4 ), the pressure relief valve ( 8 ) and closing of the proportional valves ( 3, 5 ) this 
procedure releases the pressure in the respiratory circuit.

Caution 
 
 Minimum Pressure Limit: 5 hPa 
 The maximum pressure limits the pressure in the respiratory circuit. 
o In VCV this will be the maximum pressure in the respiratory circuit. The exhalation 
valve opens to the ambient to keep this maximum pressure during the inspiratory 
 64 
MAGNAMED OxyMag – Emergency and Transport Ventilator P/N: 1600185 
cycle, if this maximum pressure is exceeded by 5 hPa the ventilator cycles to the 
expiratory phase (pressyre cycle). 
 This ventilator DOES NOT GENERATE NEGATIVE PRESSURE WHEN THE PATIENT IS 
EXHALING.

Recommended Separation Distance 
 
 Any portable equipment and radio-frequency 
cellular communication device should not be 
used nearby any part of the system, including 
cables, except at recommended separation 
distance, calculated from the equations 
appropriate to the transmitter frequency.

According to the transmitter manufacturer, P 
is the maximum nominal value of the supply in 
watts (W) and D is the recommended 
separation distance in meters (m). 
According to the local electromagnetic 
examination the permanent RF transmitter 
field intensity should be lower than the 
conformity levels in different frequency bands. 
 
ISM bands (Industrial, Scientific and Medical) between 150 kHz and 80 MHz are in the range of 6.765 MHz to 6.795 MHz; 13.553 MHz to 
13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz. 
The goal of the conformities levels in ISM frequency bands between 150 kHz and 80 MHz and in the frequency band between 80 MHz and 
2.5 GHz is to reduce the probability of interference caused by portable communication devices localized non-intentionally near the patients. 
That is the reason to use the 10/3 additional factor to calculate the recommended separation distance of the transmitters in these frequency 
bands. 
It is not possible to precisely preview the permanent transmitter fields intensity such as base stations for radio telephone (wireless cellular 
phones) and terrestrial mobile services, radio-amateur, AM and FM radio-diffusion and TV emission. It is advisable to carry out a local 
electromagnetic examination to evaluate the electromagnetic environment due to radiofrequency transmitters. Check the normal operation 
of the system if the measured field intensity in place exceeds the RF conformity level applicable described above. If an abnormal operation 
occurs, it will be necessary additional measures, such as reorientation or system placement change. The field intensity in frequency bands 
above the range of 150 kHz to 80 MHz should be lower than 1 V/m. 
Note: This directive is not applicable to all situations. The structures, objects and persons absorption or reflection can affect the 
electromagnetic propagation. 
 
 
Recommended Separation Distances 
The system can be used in an electromagnetic environment in which the radiated RF interferences are 
controlled. The customer or the system operator can help in preventing electromagnetic interference, keeping 
minimum distance between the portable equipment and cellular communication by RF (transmitters) and the 
system, according to the following recommendations and accordingly to the maximum power output from 
communication device.72

The recommended separation distance D in meters (m) from the transmitters that does not have the maximum nominal output power 
shown above can be determined by the applicable equation to the transmitter’s frequency where P is the transmitter’s nominal 
maximum output supply value in watts (W), according to the transmitter’s manufacturer. 
Note 1: From 80 MHz to 800 MHz, higher frequency band separation distance is applicable. 
Note 2: The ISM bands (Industrial, Scientific and Medical) in the range of 150 kHz to 80 MHz are of 6.765 MHz to 6.795 MHz; from 
13.553 MHz to 13.567 MHz; from 26.957 MHz to 27.283 MHz; and from 40.66 MHz to 40.70 MHz. 
Note 3: The additional 10/e factor is used to calculate the recommended transmitter separation distance in the frequency ISM bands 
between 150 kHz and 80 MHz and in the frequency band of 80 MHz to 2.5 GHz to reduce the probability of interference caused by 
portable communication devices localized non-intentionally near the patients. 
Nota 4: This directive is not applicable to all situations. The structures, objects and persons absorption or reflection can affect the 
electromagnetic propagation. 
 
 
Electrical Safety 
 
The system has connections to the display module through a serial communication cable. Below are presented 
the precautions that should be observed when these devices (non-medical equipment) with the system. 
 
Warning 
 
 The items that does not comply with the IEC 60601-1 standards cannot be placed less than 
1.5 m from the patient. 
 All the items (medical or non-medical equipment) connected to the system with 
input/output signal should be powered by an alternating current supply that uses separate 
transformer (according to the IEC-60989 standard) or having an additional earth ground 
conductor. 
 Portable multiple plugs with interrupter used in alternating current supply should comply 
with the IEC 60601-1-1 standard and cannot be installed on the ground. Do not use more 
than one portable multiple plug with interrupter. 
 Do not connect any non-medical device to the wall alternating current supply. Use an AC 
power supply with appropriate transformer. Otherwise, the leakage current enhances 
above the limits accepted by IEC 60601-1 standards under normal conditions of one single 
failure. This can cause dangerous electrical shock to the operator or to the patient. 
 After connecting any device in these power plugs, submit the hole system to a complete 
leakage current test (according to the IEC 60601-1 standard). 
 73 
MAGNAMED OxyMag – Emergency and Transport Ventilator P/N: 1600185 
 The electro-medical system operator should not touch any non-medical electrical device 
and the patient simultaneously. This can cause dangerous electrical shock to the operator 
or to the patient.
