Sleep and vent weaning

 Q: Poor sleep quality in ICU leads to prolong weaning from mechanical ventilator? (select)

A) True

B) False

Answer: A

Sleep deprivation has clearly shown to deteriorate the normal respiratory process like hypoxic and hypercapnic chemosensitivity, tongue muscle's (genioglossus) performance, and inspiratory muscles' strength. Sleep studies in ICU have shown poor sleep quality to be associated with prolonged mechanical weaning time, and noninvasive ventilation failure.
