In our previous randomised controlled trial ( RCT ) , we have shown in preterm babies ( PBs ) < 30weeks gestation that CeasIng Cpap At standarD criteriA ( CICADA ( method 1 ) ) compared with cycling off continuous positive airway pressure ( CPAP ) gradually ( method 2 ) or cycling off CPAP gradually with low flow air/oxygen during periods off CPAP ( method 3 ) reduces CPAP cessation time in PBs < 30weeks gestation .
