From: Do spontaneous and mechanical breathing have similar effects on average transpulmonary and alveolar pressure? A clinical crossover study

Fig. 4

The transalveolar pressure (i.e. the pressure distending the alveoli), which is caused by the elastic recoil of the lungs (ΔPL,el), was similar and nonsignificantly different between controlled mechanical ventilation (CMV) and any of the support levels of pressure support ventilation (high, medium, and low), either as a mean value (open symbols) or as a maximum value (closed symbols), during inspiration (a), shown as mean and standard deviation. The values measured during pressure support ventilation (PSV) and CMV were very closely correlated and close to the line of identity (dashed line), as shown in (b) (analysis restricted to breaths with similar inspiratory flow)
