title: [Measuring equipment for bedside diagnosis of respiratory function in spontaneously breathing newborn infants].
abstract: Equipment was developed for bedside lung function testing in the newborn using the simultaneous measurement of air flow rate, tidal volume, and esophageal pressure changes as a measure of transpulmonary pressure. The equipment has a number of advantages for the investigation of very low birthweight infants. A flow-through technique was used to eliminate the dead space of the face mask and a very thin micro-tipped catheter permits ready measurement of esophageal pressure. With this equipment, long-term measurements are also possible in oxygen-dependent newborns and the air-tightness of the mask can be monitored continuously. Long-time measurements in neonates are a prerequisite for standardizing the measuring conditions and adapting the duration of the measurement to the variability of the signals, especially in newborn with an irregular pattern of breathing.
