This service manual was prepared for exclusive use by Datex-Ohmeda service personnel in light of their training and experience as well as the availability to them of parts, proper tools and test equipment. The Aestiva Anesthesia Machine has its own service manual (Stock Number 1006-0452-000). Read and follow all warnings and cautions. Other symbols replace words on the equipment or in Datex-Ohmeda manuals. No one device or manual uses all of the symbols. These symbols include:. Variability in steps Vacuum inlet This way up Suction bottle outlet Lamp, lighting, illumination Cylinder Lock Isolation transformer Unlock Linkage system Close drain Risk of Explosion.The primary regulator is set to The ventilator is designed to be used as a medical device assisting in the delivery of anesthesia and is part of the Aestiva Anesthesia Machine. The Aestiva 7900 Ventilator is not a portable unit. Batteries for the battery ventilator are used as back up power in case of a power failure. Thus the battery is in a float charge state most of the time. In the original Aestiva 7900 machines, these functions are on a separate CPU board. For current machines, they are part of the digital circuits section of the integrated CPU board. This memory contains the real time operating system (RTOS) and software code.

The Flash memory devices are socketed. System RAM This memory consists of two 128 K x 16 CMOS static RAMs with on-board expansion capability to 512K x 16 SRAMs. Multiple level 7 interrupts will occur prior to a reset. The output of this watchdog is connected to IRQ7 on the 68340 processor. The manifold pressure, patient pressure, inspiratory flow and expiratory flow System signal inputs to the multiplexer are filtered with an antialiasing filter. Other inputs are filtered by low pass filters. All of these signals are routed through a single connector from the microcontroller board to the front panel assembly. It also passes different switch functions through to the ventilator control module. These switches are used to show the position of covers, breathing circuit modules and pneumatic controls in the breathing circuit. The supply is filtered at the SIB. There are two regulators on the SIB that are supplied by the 12V to 15V supply. This normally closed switch signal is sent to the Aestiva 7900 Ventilator CPU board.This valve provides a shutoff of the supply gas to the (GIV) ventilator when the ventilator is not in use. This valve also shuts off supply gas to the ventilator under failure conditions detected by the CPU or over-pressure switch. The ventilator is programmed to supply a specified number of breaths per valve minute to the patient. If, in between one of these programmed cycles, the patient needs a breath (spontaneous), the free breathing valve permits the patient to inhale. Perform calibration on flow sensors, pressure sensitivity, flow valve and bleed resistor.You must perform Section 3.1 Post-service checkout after performing any maintenance, service or repair. Failure to do so may result in patient injury. CAUTION Section 4a should only be used with version 4.X software. Select “Service Mode” and push the adjustment knob.

The Service Mode main menu allows navigation to the individual menus for alarm or error logs, calibrations, system configurations, diagnostic tests and tools, and user selected defaults. An alarm message that results from these special types of alarms is considered an error alarm. To ensure the specified accuracy, the altitude setting should be set to the specific altitude where each machine is located. These machines should have the Heliox Mode “On”.However, the majority of service confirmation and calibration modes are shown in English. The other language choices are shown in specific language text with the exception of Japanese which is shown in English. The values range from 1 to 10, with 10 having the most screen contrast.Defaults Settings related to optional ventilation modes will only appear in the User Select Defaults if the optional modes are active.When Start Test is selected the series of tests begins to run. When each Memory test is running, the word “Testing...” appears after the test name.It writes a certain pattern to a block of memory and then reads back that block of memory. If the bit pattern that was written is not the same bit pattern that it reads back, the test fails. It then opens the flow valve in increments until the flow valve is completely open.The software opens the flow valve to a value Pressure Limit Switch where pressure continues to increase. Alarm The 5-Volt supply (VDD) is derived in the power section of the control board. It is used to power the digital circuits throughout the ventilator. This checks the battery charge current.

Switches Press each button and turn the encoder one full turn in both directions. When a button is pressed and held, the icon on the screen next to the button will contain an “x”. It allows you to manually control the flow valve setting from 0 (closed) to Tool 120 LPM, in 1 LPM increments, and observe key pressure and flow measurements on the same screen. Note: a circle module is required for all calibrations. This calibration is not an automated calibration. It Sensitivity prompts the user to follow a set of procedural steps to perform the calibration. Other than the setup procedure, this calibration is completely automated.After the setting or calibration is properly completed, the text for that setting or calibration is removed from the list. You must perform Section 3.1 Post-service checkout after performing any maintenance, service or repair. Failure to do so may result in patient injury. CAUTION Section 4b should only be used with versions 1.X and 3.X software. The proprietary channel is used connection for software development testing and manufacturing test. Select “Service Mode” and push the adjustment knob. The service mode Main Menu displays all selectable service tests. Software revision 3.X adds several menu items to the service mode. If this test fails, the CPU did not perform an integer instruction correctly, or the CPU register(s) have failed. It writes a certain bit pattern to a block of memory and then reads that block of memory. It writes a certain pattern to a block of memory and then reads that block of memory. If the bit pattern that was written is not the same as the bit pattern read back, the test fails. The software sets up the serial ports so data sent out the serial ports is echoed directly back to that serial port. The test fails if the data sent out is not equal to the data received. It then opens the flow valve in increments until the flow valve is completely open.

The software opens the flow valve to a value (Drive Pressure Limit) where pressure continues to increase. Refer to the following table for additional details for each of the displayed channels. This checks to see if the battery charge is greater than or equal to 12.5 volts. If it is less than 12.5 Status volts, the battery charge status displays that the battery is not charged. If it is greater than or equal to 12.5 volts, the battery charge status displays that the battery is charged. The Error code, the Address, and the software revision are important pieces of information if technical support is required. Note that the system time is listed in ticks. It allows you to manually control the flow valve setting from 0 (closed) to 120 LPM, in 1 LPM increments, and observe key pressure and flow measurements on the same screen. By using the patient circuit to establish a closed loop, you can measure the leak rate. The leak rate is equal to the fresh gas flow needed to maintain 30 cm H O. The Adjust Drive Gas Regulator procedure establishes the required flow rate through the drive gas regulator for proper calibration. Remarks The drive gas regulator should provide a constant gas input pressure of 172 kPa (25 psi). Set the appropriate altitude for the machine location.This calibration is not an automated calibration. It Sensitivity Calibration prompts the user to follow a set of procedural steps to perform the calibration. Other than the setup procedure, this calibration is completely automated. Bleed Resistor Note: Step 5 in software revision 1.0 indicates that you should set the fresh gas flow to “10 Lpm”. After the setting or calibration is properly completed, the text for that setting or calibration is removed from the list. If the “Sensor(s) Cal Due”.
