title: The Penlon Bromsgrove high frequency jet ventilator for adult and paediatric use. A solution to the problem of humidification.
abstract: The Penlon Bromsgrove is a new high frequency jet ventilator, suitable for use in both adults and children. The jet stream is humidified by means of an integral in-line Bernoulli nebuliser. The self-recharging nebuliser can also convey drugs directly to the airways in the form of an aerosol. Alarms and fail-safe systems are incorporated. A pressure gauge continuously displays the jet drive pressure. There are two digital LED displays; one shows jet frequency in breaths per minute; the other, the jet drive pressure, minimum, maximum and mean patient airway pressures. Two fail-safe systems ensure that these pressures do not become excessive. Both audible and visual alarms are provided. The prototype has proved to be quiet and completely reliable over more than 4000 hours use, with no bronchoscopic or histological evidence of ineffective humidification.
