Abstract: Examples described herein include systems and ventilators for performing automated ventilation procedures. The automated ventilation procedure may automatically adjust ventilator parameters (e.g., PEEP) to perform a procedure such as a recruitment maneuver, PEEP titration, a recruitability assessment, or combinations thereof.

Abstract: A flow sensor comprising a tubular body having a bore, a ventilator end, a patient end, and a central region; a restrictor assembly located adjacent the central region, and fluidly connected to the bore, the restrictor assembly having a first pressure port having a first diameter, proximate the patient end, and fluidly connected to a second portion of a first lumen; a second pressure port having a second diameter, proximate the ventilator end, and fluidly connected to a second portion of a second lumen; and a restrictor post having a length connected to a shaft having a width; wherein a first portion of the first lumen is perpendicular to a second portion of the first lumen, and a first portion of the second lumen is perpendicular to a second portion of the second lumen.
