B Page 15 VELA Ventilator Systems Service Manual 3 Chapter 2: Theory of Operation General Device Description The VELA Ventilator uses a revolutionary turbine gas delivery system with sophisticated microprocessor control. Its Graphical User Interface provides support for pediatric to adult patients. The VELA can deliver clinically advanced modes of ventilation like Pressure Support, APRV, NPPV and PRVC, and can be powered with an internal battery or AC power for a more extensive patient range. Pneumatic System Overview The VELA ventilator pneumatic system is electromechanical and comprises four major subsystems, each containing several components. These systems are the flow delivery system, the exhalation system, the safety system and the inspiratory hold valve. Individual subsystems are discussed in detail below. Flow Delivery System This electromechanical system controls all inspiratory flow to the patient. The system delivers flow to satisfy criteria for many breath types, including volume controlled, pressure controlled, pressure supported, APRV, NPPV and PRVC. The system comprises a turbine, differential pressure transducer, 2 auto-zero valves, and an optical encoder speed transducer. When a breath is initiated, the microprocessor controls the speed of the turbine to achieve the required flow rate. The speed and differential pressure transducer signals function as control inputs to ensure that the proper flow rate is delivered even when backpressure varies. Periodically, the auto zero valves activate to reference both sides of the differential pressure transducer to ambient pressure. The offset is recorded by the microprocessor, and is used as a correction for future pressure measurements. This compensates for long term and temperature drift. Materials exposed to patient gases include compatible plastics, aluminum, and plated steel. Exhalation System The exhalation system controls the flow of gas from the patient’s lungs during the exhalation phase of a breath. This electromechanical subsystem is made up of an exhalation valve, a flow transducer, a differential pressure transducer, an airway pressure transducer, and three auto zero solenoid valves. During exhalation, the outflow of gases is regulated by the exhalation valve to achieve the set PEEP. The gas flow travels through the flow transducer. The flow transducer is a variable orifice type and creates a differential pressure proportional to flow. This differential pressure is transmitted to the differential pressure transducer, which converts the pressure signal to an electrical signal. The microprocessor uses this signal for flow triggering and to monitor exhaled tidal volume. The airway pressure transducer reads pressure in the exhalation leg of the patient circuit. This signal is used as a feedback signal for controlling PEEP, pressure control, pressure support, and various pressure monitors. Periodically, the auto zero valves activate to reference the differential and airway pressure transducers to ambient pressure. The offset is recorded by the microprocessor, and is used as an offset for future pressure measurements. Materials exposed to patient gases include compatible plastics, aluminum, and stainless steel. L2859-101 Rev. B Page 16 4 Service Manual VELA Ventilator Systems Safety System The mechanical safety system ensures that the patient can breath spontaneously from room air and that the patient pressure is limited to a maximum preset value in the event of a ventilator malfunction. This mechanical system consists of a pressure relief valve and a sub ambient relief valve. In the event of a ventilator malfunction that results in high pressure, the pressure is limited by a relief valve. The relief valve consists of a user-adjustable, spring-loaded poppet acting against a seat. In the event the ventilator fails to deliver a breath, the patient may inspire spontaneously by drawing room air through the sub ambient relief valve. Materials exposed to patient gas are aluminum, compatible rubber, and compatible plastics. Inspiratory Hold Valve The inspiratory hold valve is an electromechanical solenoid valve. If activated, the inspiratory hold valve blocks flow between the flow delivery system and the patient. This valve is activate during inspiratory hold and maximum inspiratory pressure maneuvers. Materials exposed to patient gases are aluminum and compatible rubber and plastic. Oxygen Blending System The oxygen blending system is made up of an O2 inlet transducer, an O2 inlet pressure regulator, seven solenoid valves, five flow orifices, one nebulizer orifice, an inlet filter, and an accumulator. When a breath is initiated, the turbine draws mixed gas from the accumulator. Filtered air is drawn into the accumulator through the filter. Oxygen is supplied to the accumulator through the solenoids and orifices. The microprocessor opens and closes the valves as required to supply the correct amount of oxygen to satisfy the O2 setting and the flow demand. The signal from the O2 inlet pressure transducer is used to compensate delivered O2 for O2 inlet pressure variations. The blender can be used to supply nebulized flow at 100 oxygen. A safety solenoid is used to shut off the flow of oxygen when the ventilator is turned off or has gone inoperative. The O2 inlet pressure regulator helps minimize variations in the oxygen supply. Surfaces exposed to patient gas are constructed from compatible plastics, plated steel, and aluminum. There is also an oxygen inlet port, which allows for low-flow titration of oxygen into the gas output of this device. Electronic Overview The VELA ventilator electronic system is comprised of several subsystems, each containing numerous components. These subsystems are the GUI System, the Power System, the Main Microprocessor System, and the Exhalation and Flow Delivery systems. Individual subsystems are discussed in detail. User interface module (UIM) The UIM consists of a 10.4-inch, 800x600 active matrix LCD with an analog resistive touch screen overlay, a back light inverter, a set of membrane key panels, an optical encoder, and the Main System PCB. Software and the touch screen provide a set of context sensitive soft keys. The membrane panel provides a set of hard (permanent) keys for dedicated functions. Selecting the function with a soft key and adjusting the setting using the optical encoder changes a parameter. A parameter is accepted or canceled by pressing the appropriate membrane key. The UIM performs all ventilator control functions, gas calculations, monitoring and user interface functions. The UIM uses a Graphical User Interface (GUI) via the active matrix SVGA LCD and resistive touch screen to provide system and patient information to the user and to allow the user to modify ventilator settings. 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. L2859-101 Rev. B Page 17 VELA Ventilator Systems Service Manual 5 Liquid Crystal Display The liquid crystal display (LCD) provides graphical and digital feedback to the clinician. The panel is a 10.4” SVGA, 800x600 pixel, active matrix LCD. The LCD is used to implement the graphical user interface (GUI). It provides all of the adjustable controls and alarms, as well as displays waveforms, loops, digital monitors and alarm status in real time. Touch Screen The touch screen is a 10.
