The article offers news briefs related to medical research. Canadian research suggests that patients with chronic obstructive pulmonary disease (COPD) may benefit from breathing a mixture of helium and oxygen than natural air during pulmonary rehabilitation. According to the U.S. research, vitamin K is no better than placebo in treating the effects of warfarin overdose. It also notes that playing computer games can delay the onset of dementia.

    Objective. Airway pressure release ventilation (APRV) is a ventilatory mode with a time cycled change between an upper (Phigh) and lower (Plow) airway pressure level. APRV is unique because it allows unrestricted spontaneous breathing throughout the ventilatory cycle. We studied the influence of...
