Fig. 1From: Can ventilator settings reduce the negative effects of endotracheal suctioning? Investigations in a mechanical lung modelMechanical lung model test system: Design setup and connections. The term “model airways” (MA) describes the air space distal to the ETT and is comprised of an air chamber, two test model bellows and connecting tubes. Pressures distal to the obstruction were measured by a transducer. Pressures proximal to the obstruction were measured in the ventilator circuitBack to article page
