Abstract

aparelho e método para acionar um sensor em uma reivindicação de prioridade de ventilador. um ventilador inclui um sensor para monitorar uma característica associada com a entrega de gás ao paciente, tal como pressão. uma fonte de alimentação do sensor (100,130) está alimentando um sensor na forma de uma ponte wheatstone. uma primeira extremidade (104) da ponte está acoplada a uma primeira fonte de voltagem positiva (112, 142) e uma segunda extremidade (116) está acoplada a uma segunda fonte de voltagem positiva (118, 156, 180). um capacitor (120) está acoplado à segunda extremidade da ponte. um controlador (50) controla a primeira e a segunda fonte de voltagem positiva tal como para (a) desabilitar o sensor através de levar a primeira fonte de voltagem positiva a fornecer voltagem substancialmente zero à primeira extremidade da ponte wheatstone e através de levar a segunda fonte de voltagem positiva a fornecer uma voltagem positiva à segunda extremidade do capacitor, e para (b) habilitar o sensor através de levar a primeira fonte de voltagem positiva a fornecer uma voltagem positiva à primeira extremidade da ponte wheatstone e através de levar a segunda fonte de voltagem positiva a fornecer uma voltagem decrescente à segunda extremidade do capacitor.
