The CPAP-test for an exact indication of CPAP-therapy

Abstract To summarize, it can be stated that the CPAP-test is, so to speak, a therapy ‘ex juvantibus’ and enables an exact indication for the application of the CPAP-therapy. In our experience the CPAP-test is positive in several respiratory disorders of the newborn, not only in the RDS. Probably, the basis of all these disorders is a functional R-L shunt, and in all these disorders the CPAP-therapy is indicated.
