The bias flow nitrogen washout technique for measuring the functional residual capacity in infants. M.G. Morris, P. Gustafsson, R. Tepper, M. Gappa, J. Stocks, on behalf of the ERS/ATS Task Force on Standards for Infant Respiratory Function Testing. #ERS Journals Ltd 2001. ABSTRACT: The functional residual capacity (FRC) is the most commonly measured static lung volume in infants. It is importa...

Respiratory changes resulting from stepwise intrathoracic injections of 4 ml of either room air or warm (37 degrees C) Haemaccel, simulating pneumothorax and pleural effusion, respectively, were evaluated in anaesthetized, paralysed, and mechanically-ventilated rats. Respiratory system, lung, and chest wall resistances and elastances (static and dynamic) were determined in 14 animals. For this ...

BACKGROUND Initial ventilation strategy may play an important role in the development of bronchopulmonary dysplasia in very preterm infants. Early nasal continuous positive airway pressure is an accepted approach, but randomized clinical trials are lacking. Our aim was to determine whether early nasal continuous positive airway pressure, preceded by a sustained inflation, is more effective and ...

Measurement of lung volumes at end expiratory level and assessment of ventilation inhomogeneity is important for respiratory management in infants with lung disease. This study compared multiple breath nitrogen washout was compared with body plethysmography to measure functional residual capacity in infants and assessed ventilation inhomogeneity using mean dilution numbers and alveolar based ga...
