Conference paper


For more than 30 years acute respiratory failure (ARF) has been one of the most frequent causes of admission to the intensive care unit (ICU) [1]. The treatment of ARF is described as conservative if the patient is managed without intubation or tracheostomy and mechanical ventilation (MV). Many cases of ARF can be treated in a conservative way. MV via endotracheal (ET) tube or tracheostomy has been indicated if conservative treatment fails. Classic indications for MV are: deterioration of consciousness, cardiac or respiratory arrest, exhaustion and extreme fatigue [2] . The aims of MV are: 1) to save time in order to let ARF subside, and 2) to unload the respiratory muscles (RM) in order to let them rest and recover [3]. However, it is still difficult to predict which patients will require MV and when it should be instituted. Furthermore there is no general agreement about which kind of ventilatory support is preferable.
