ABSTRACT
We have designed a new endotracheal flowmeter to measure tidal volume, phasic and mean airway pressures, inspiratory time, and end-tidal PCO2 and PO2 in intubated infants. The flowmeter is light (11 g) and adds minimal dead space (1.0 ml) and resistance (2 cmH2O X 100 ml- X s) to the infant's airway. The volume signal (less than or equal to 10 ml) is linear to 7 Hz, and end-tidal gases can be measured at respiratory rates of 90 breaths/min. This flowmeter is particularly valuable for evaluation of rapid mechanical ventilation of very low birth weight infants.
