The Consolidated Ventilator Interface Board (cVIB) Assembly is a specially designed control board intended for use in Avance™ and Aisys™ anesthesia system. The assembly is comprised of the Consolidated Ventilator Interface Board (cVIB), colored couplings (white, black, blue, yellow), sleeves, a tube and label. The cVIB is referred as Central Processing Unit (CPU) of the anesthesia system and it interfaces with the ventilator of the Anesthesia Control Board (ACB). The ventilator interface section of the board is managed by an Atmel® ATMEGA16 microcontroller. The interface board controls the switches and components such as the inspiratory and expiratory flow transducers, patient airway and manifold transducers, airway over-pressure, oxygen sensor, ABS switches, ACGO switches, bag/vent switch, O₂ flush switch, gas inlet valve, inspiratory flow valve, pipeline pressure transducers, cylinder pressure transducers, mixer, vaporizer, task Light and machine on/standby switch.
