Fig 4. Dynamic compliance (Cdyn) of surfactant-depleted rabbits managed with non-invasive ventilation.
To the left of the dashed line, the baseline and post-surfactant depletion Cdyn values of all the animals featured in the study are given. To the right of the dashed line, the Cdyn values of the different groups after 180 minutes of management with NIV are shown. Surfactant-treated groups are represented by the box-plots with a grey filling, whereas the groups merely treated with NIV are represented by the white box-plots. The small squares within each box-plot indicate the mean of the group. The whiskers indicate the maximum and minimum values observed for each group. # P < 0.01 vs. SNIPPV+SF group. NCPAP: nasal continuous positive airway pressure, SF: surfactant, NIPPV: nasal (non-synchronized) intermittent positive pressure ventilation, and SNIPPV: synchronized NIPPV.
