Abstract:
A valve () for controlling pressure in a ventilation system is disclosed. The valve comprises an electromagnet (), a shaft () connected to the electromagnet, and a diaphragm () connected to the shaft, wherein the electromagnet applies force to the diaphragm based on an input. The ventilation system comprises a ventilator () connected to a patient circuit (), the valve () controlling pressure in the ventilation system, and a controller () connected to the valve and configured to provide the input to the valve.
A ventilator includes a first pathway configured to supply a first gas; a second pathway configured to supply a second gas; a bypass element configured to provide a portion of the first gas and a portion of the second gas, the bypass element comprising a rib adjacent to a bypass conduit, wherein fluid flow is substantially laminar adjacent to the conduit. A bypass element is described.

Abstract:
A method for controlling a ventilator includes the steps of providing an inhalation pressure limit, determining when a pressure in a connection to a patient circuit is greater than the inhalation pressure limit, and opening the valve when the pressure is greater than the inhalation pressure limit. An associated computer readable medium for controlling the method is also described.
