The Main System PCB handles all user interface requirements, including updating the active matrix liquid crystal display (LCD), monitoring the membrane keypad, analog resistive touch screen, and optical encoder for activity.
  • Page 17 Chapter 2: Theory of Operation 2.4.2 Power System The Power System conditions and controls electrical energy from the AC line input and the internal batteries. The Power System supplies 24VDC, 8VDC, and 5VDC to the Main System PCB. When energy is available from the AC line, the ventilator operates from this source, and also recharges the internal batteries.
  • Page 18 Chapter 2: Theory of Operation 2.4.5 Exhalation System The electrical portion of the exhalation system is comprised of the Exhalation Valve Driver Circuitry. The driver converts the low voltage signal output by a D-to-A converter into a controlled constant current which energizes the linear solenoid positioner in the exhalation valve. 2.4.6 Flow Delivery System The electrical portion of the flow delivery system is comprised of a 3 Phase Brushless Motor Driver, and an Optical Speed Transducer.

  • Page 73 Why does the O2 Inlet fluctuate so much when my wall pressure is consistent? The VELA ventilator does not have a pressurized accumulator like many ventilators do that add a volume of gas to equal out pressures during higher demands of gas flow. With that in mind when the FiO2 settings are set above 21% and a demand by means of a delivered breath is made on the blender, the solenoids will servo open and closed.
