Change of cardiorespiratory parameters before and after treatment. Individual changes of the heart rate, breathing frequency, blood pCO₂ and FiO₂ before and within 2 hours, and the chest X-ray score before and within 24 hours after administration of DNase in 30 children treated for atelectasis. Although changes were statistically significant, a significant overlap was present before and after recombinant human DNase treatment (see also Table 1).
