1. Oscillation volumes (Vosc; white box) and transcutaneous carbon dioxide pressure (Ptc,CO2; grey box) levels before, during and after a 5-cmH2O increase in pressure amplitude with high-frequency oscillatory ventilation in pre-term infants.
Oscillation volumes (Vosc; white box) and transcutaneous carbon dioxide pressure (Ptc,CO2; grey box) levels before, during and after a 5-cmH2O increase in pressure amplitude with high-frequency oscillatory ventilation in pre-term infants. The initial Vosc before the pressure amplitude increase was set at 100%. The median, 25th and 75th percentile, and the minimum and maximum values of 10 infants are shown. *: p<0.05 after versus before the increase in pressure amplitude; **: p<0.01 during versus before the increase in pressure amplitude; #: p<0.05 after versus during the increase in pressure amplitude; ##: p<0.01 after versus during the increase in pressure amplitude.
