title: Pneumotachography in intubated infants.
abstract: A new flat-bodied pneumotachograph head is described which can be readily interposed between a commercially available endotracheal tube connector on one side and a suitable low dead space attachment on the other. The head was designed to enable the respiratory flow of infants and neonates to be measured both easily and accurately, and without adding appreciably to the work of breathing. The method used to heat the head, and to heat and humidify the inspired gases are also detailed. The underlying aim has been to record inspiratory and expiratory flow as accurately as is possible within the bounds of practical clinical measurement.
