The ventilatory performance of four portable emergency ventilators (Logic 07, Motivus Oxylog and Pneupac II) was tested on a lung model. The model consisted of one common (tracheal) tube, two separate (bronchial) tubes in which different obstructions could be applied, and two glass jars filled with water to suitable compliances. Dialled volume was compared to measured volume. The gas distribution produced by the different ventilators was also studied. It was found that alt lour ventilators could distribute gas to the lungs. The ventilators Logic 07 and Oxylog had acceptable relationships between dialled and measured volume/frequency and they also produced a good final distribution.
