Pop-off system for the high flow IMV reservoir bag

  • 15 Accesses

  • 1 Citations


A pop-off valve system for use with intermittent mandatory ventilation that employs high flow and a reservoir bag is described. It ensures constancy of the mechanical tidal volume regardless of the flow rate of fresh gases into the reservoir bag of the spontaneous breathing circuit.
