简要总结
Sedation is widely used in mechanically ventilated patients. Propofol, benzodiazepines and opioids are the most used drugs. The study hypothesis is that sedation with remifentanil (an opioid drug) could improved respiratory pattern and effort in mechanically ventilated patients with rapid shallow breathing or high respiratory rate.

研究组 & 干预措施
treatment
Any patient alternatively receive both remifentanil and isotonic saline (placebo)infusion. The order of infusion is randomized. An interval of 30 minutes is planned between the two infusions.
干预措施: remifentanil (Drug)
