Abstract:
A ventilator system for assisting a patient in breathing comprising:a supply of inhalation respiratory gases; a respiratory conduit providing a flow pathway for an inhalation and exhalation respiratory gas flowing therethrough between said supply of inhalation respiratory gases and the patient; a valve disposed within said respiratory conduit for controlling the flow of inhalation and exhalation respiratory gases; a flow module holder located within the conduit between said valve and the patient; and a respiratory gas analyzer located between said valve and the patient, the analyzer comprising: a flow module, adapted to be placed within the flow module holder in the conduit, so that the inhalation and exhalation respiratory gases pass through a flow path of the flow module, the flow module containing a flow rate sensor disposed in the flow path of the flow module for determining a flow rate of the inhalation and exhalation respiratory gases, and an electronics module, adapted to be integrally connected to the flow module, and adapted to calculate a respiratory parameter using the determined flow rate of the inhalation and exhalation respiratory gases flowing through the flow path.
