摘要：
In various embodiments, an electronic flow selector of a fluid flow control system may be used to select a flow rate of a fluid. When the system is in an electronic mode, an encoder may electronically encode the fluid flow selection. A controller may receive the electronically encoded flow selection and transmit a corresponding control signal to an electronic valve to allow the fluid to flow at the selected flow rate. When the system is in a manual mode, backup manual flow selectors may be used to directly control the flow rate of a fluid. When the system is in a manual mode, the mechanical backup flow selectors may be in a deployed position. When the system is in an electronic mode, the mechanical backup flow selectors may be in a retracted position. Particular applications to gases and anesthesia delivery are disclosed herein.
