Fig. 4From: Continuous external negative pressure improves oxygenation and respiratory mechanics in Experimental Lung Injury in Pigs – A pilot proof-of-concept trialCentre of aeration (left) and centre of ventilation (right) as a percentage from dorsal. Legend: CENP, continuous external negative pressure; PEEP, positive end-expiratory pressure. Triangles indicate different shell positions (abdomen and thorax), colours represent different PEEP levels, super-posed numbers indicate significance (P < 0.05) of the respective CENP level compared with the CENP level of the number and stars indicate the difference between both positionsBack to article page
