Breas Vivo 30, 40 Ventilator Service Manual
Breas Vivo 30 and Vivo 40 are pressure-supported and pressure-controlled ventilators for patients who require intermittent support by mechanical ventilation. These ventilators have three modes of operation: PSV, PCV, and CPAP. PSV and PCV modes have adjustable trigger sensitivity settings which allow the patient to initiate ventilator-assisted breaths. The PCV mode provides assisted or controlled pressure-regulated breathing, while the PSV mode offers expiratory sense adjustment for patient-specific needs. The CPAP mode provides continuous positive airway pressure. The logs of the Vivo 30/40 can be downloaded to a PC for analysis with the Vivo 30/40 PC Software.

1.1
About the Vivo 30/40 Ventilator
1.1.1
Function
The Vivo 30/40 is a pressure-supported and pressure-controlled ventilator for patients who require intermittent support by mechanical ventilation.
It has three modes of operation: PSV, PCV, and CPAP. The PSV and PCV modes have an adjustable trigger sensitivity setting which allows the patient to initiate ventilator-assisted breaths.
In the PCV mode (Pressure Controlled Ventilation), the ventilator provides assisted or controlled pressure-regulated breathing.
In the PSV mode (Pressure Support Ventilation), the ventilator’s expiratory sense can also be adjusted allowing the ventilator to more easily match each patient’s needs.
In the CPAP mode (Continuous Positive Airway Pressure), the ventilator provides a continuous positive airway pressure.
The logs of the Vivo 30/40 can be downloaded to a PC, printed out, and analysed via the
Vivo 30/40 PC Software. For more information about the Vivo 30/40 PC Software, please contact your Breas representative.
1.1.2
Intended Use
For a detailed description on intended use, refer to the Vivo 30/40 Clinician's or User Manuals.
1.1.3
Design
The Vivo 30/40 is constructed around a blower assembly.
An electronically controlled stepmotor rotates a valve to control the pressure. A microprocessor controls the correct speed of the blower motor and its power supply by means of calculations based on the settings for pressure, rate, inspiration time, etc. The pressure and trigger settings are monitored at the same time.

Electrical Safety Precautions
Electrical safety measurements must be made in accordance with IEC 601.
Use an automatic electrical safety tester to make the measurements. All tests must be performed in accordance with class II type BF.
Supply Voltage
Note the power voltage reading.
The voltage must be noted at each service check, as the currents measured are directly in relation to the supply voltage. This allows all measurements made on the same ventilator to be compared with measurements made on different occasions.
Insulation
The insulation resistance is measured using a 500 V DC power supply. The most suitable method is to connect the plus lead to the two ventilator power socket pins, and the minus lead to the casing or the patient air connector. The measurements made during the delivery inspection can be used as reference values for measurements made during future services. If no reference values are available, the value for the insulation resistance should be >20 M
Ω
.
Leakage Currents
The leakage currents are measured at different parts of the ventilator using an RC circuit to earth.
Make the measurements partly at normal case (NC) and at the single fault condition (SFC). Reverse the polarity of the power supply and note the highest value.
Leakage currents to earth must not exceed the stated limit values.
Leakage Currents from the Casing
The leakage current of the casing is measured at an unpainted point, for example, the head of a screw.
Limit values: NC <0.1 mA
SFC <0.5 mA
Break neutral for SFC.
Patient Leakage Currents
The patient leakage current is measured between the patient connector and earth.
Limit values: NC <0.1 mA
SFC <0.5 mA
Break neutral for SFC.
Leakage Currents with Mains Power Supply at the Patient-connected Part
This test must be done using an automatic electrical safety tester with this function. See the safety instructions for the tester.
Limit value: SFC <5 mA

PSU board contains the switch mode power supply (SMPS) built on the double ended flyback topology. The converter is powered with mains 100-240 V AC, +10%, -20% (i.e. 80 V AC-264 V AC).
Power Source Selection
There are three power inputs (two for Vivo 30), Mains, External DC (EXT DC) and internal battery
(INT DC, Vivo 40 only).
The three power sources are controlled by the main processor on the CPU board. The processor senses status for each source to decides if to disable mains and enable any DC source.
48 Electronics
Breas Vivo 30/40 Service Manual
Doc. 003823 En Z-1
Voltage Converter
The converter is a boost converter that steps up EXT DC or INT DC to +30 V DC, the nominal value for net VM (Voltage Motor). When Vivo 30/40 is running on mains, the DC step up converter is disabled because of the already +30 V DC from the SMPS.
Brush less DC (BLDC) Motor Controller
The BLDC amplifier is based on a three-phase inverter controlled by a MC33035 motor control circuit. The main processor regulates the speed with a 0-5 V analogue signal into the MC33035P. The main processor can also brake the BLDC motor via the control circuit. To determine if the fan is running, the main processor senses a hall element from the BLDC motor. The control circuit also has a built-in over current protection.
Internal Battery Pack Connector (Vivo 40 only)
Vivo 40 is equipped with an internal battery pack, accessed from the PSU-board via 2x6 pole
Preci-dip connectors. The battery pack contains its own charging processor and either supply
Vivo 40 with power, or gets charging power from Vivo 40.
The main unit supplies the battery pack with +5 V from the CPU-board through this board.

Main Processor and User Interface (UI) Processor
The processing core of the main unit is two M16C62P Microcontrollers.
The main processor has a supply voltage of +5 V and is not operating when Vivo 30/40 is shut of.
The UI processor is supplied with both +5 V (signal side) and +3,3 V (data side).
The UI processor is battery backed up and will operate in sleep mode when the Vivo 30/40 is switched off.
Compact Flash Memory Interface
The main processor can transfer the data log from the memory to the compact flash memory.
Doc. 003823 En Z-1
Display
The display used is a graphic type and have a visible area of approx. 60x80 mm, with a resolution of
240x320 pixels.
To drive the display a display controller is used.
RJ45 Connector
To communicate with a PC, the Vivo 30/40 uses a RS232 interface.
Pressure Sensors
Vivo 30/40 is equipped with two pressure sensors for redundancy. The main processor gets input from both pressure sensors, but the UI processor only gets input from one of the sensors. This means that both processors supervise the actual pressure and have the availability to stop the blower in case of an error condition.
Mass Flow Sensor
The mass flow sensor is used for air flow measurements.
Alarm Beeper
The alarm beeper is a 25 mm plastic membrane loudspeaker, powered by a 1 W bridge-connected audio amplifier. The alarm is generated by hardware and either of the two CPU:s can start and stop the alarm.
Stepper Motor Amplifier
The Vivo 30/40 uses a valve for controlling the exhalation phase. This valve is controlled by a stepper motor which is controlled by the main processor.
Voltage Regulators
The CPU board contains voltage regulators for 3,3 V, 5 V, 8 V, 10 V and 24 V.

Notes
• At 80 MHz and 800 MHz, the higher frequency range applies.
• These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed
RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Vivo 30/40 is used exceeds the applicable RF compliance level above, the Vivo 30/40 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Vivo 30/40.
