Abstract:: In infancy respiratory disorders are very frequent and lung function measurements are essential for their assessment. As infants do not cooperate with pulmonary function testing special techniques have to be developed for this age group. Diagnostic: Rapid thoracic compression methods have been widely adopted for quantification of actual airway caliber in healthy infants as well as in those with different lung diseases. The "squeeze-technique" uses an inflatable jacket tightly surrounding chest and abdomen of the infant. Following a tidal inspiration the jacket is rapidly filled with air effecting a forced expiration by compression of chest and abdomen. Analysis for forced expiratory flow measured by this method has been proven as useful for epidemiological studies as well as for clinical purposes. Major disadvantages are the relatively high intrasubject variability of the measured parameter and the representation of only a small volume range of vital capacity as the compression-manoeuvre starts from end-tidal inspiration. Rapid lung inflation to a predetermined inflation pressure through a modified diaphragm pump prior to thoracic compression allows assessment of infant lung function over an extended volume range. Volume-time parameters obtained from this recently introduced new method, the so called "pump and squeeze-technique: have less intrasubject variability than the standardized flow parameter obtained from the conventional "squeeze-technique". Further studies should evaluate the clinical application of this new method.
