Patient-controlled sedation: a novel approach to sedation management for mechanically ventilated patients.
Patient self-administration of medications for analgesia and procedural sedation is common. However, it is not known whether mechanically ventilated ICU patients can self-administer their own sedation to manage symptoms. ⋯ PCS warrants further investigation as a means to promote comfort in mechanically ventilated critically ill patients.

Randomized Controlled Trial Comparative Study
Does a low-density gas mixture or oxygen supplementation improve exercise training in COPD?
Low-density gas mixtures and oxygen (O₂) supplementation are known to improve physical performance and ventilatory adaptation during incremental maximal exercise in COPD. We investigated whether their combined use during intense physical training is also effective in ameliorating exercise tolerance in patients affected by moderate to severe COPD. ⋯ We concluded that the use of a low-density gas mixture or O₂ supplementation does not contribute to improved exercise performance in patients with moderate to severe COPD without a significantly decreased diffusion lung capacity for CO who are able to tolerate intense physical training.
