The history of respiratory assistance has been marked by tremendous time lags between laboratory developments and clinical application. The events of more recent history and the introduction of radically new techniques using microprocessor technology may prove that an exponential reduction of this time lag is now in progress. In the past 50 years a number(More)
PURPOSE Synchronised intermittent mandatory ventilation (SIMV) and high-frequency jet ventilation (HFJV) are accepted ventilatory strategies for treatment of respiratory distress syndrome (RDS) in preterm babies. We hypothesised that SIMV and HFJV both facilitate adequate oxygenation and ventilation but that HFJV is associated with less lung injury. (More)
Increasing positive end-expiratory pressure (PEEP) is advocated to recruit alveoli during high-frequency jet ventilation (HFJV), but its effect on cardiopulmonary physiology and lung injury is poorly documented. We hypothesized that high PEEP would recruit alveoli and reduce lung injury but compromise pulmonary blood flow (PBF). Preterm lambs of(More)
