Figure 1

Respiratory rate (A), inspiratory time (B), expiratory time (C), and I:E ratio (D) during the two baseline periods of CPAP before and after PAV, and during PAV. Data are presented for the periods before and after lung lavage and after instillation of surfactant. Significant differences between PAV and the preceding and succeeding CPAP are marked with *, †, ‡ or § and their respective p values are presented. Means ± standard errors of the mean are shown.
