Ventilatory failure, ventilator support, and ventilator weaning.

摘要: The development of acute ventilatory failure represents an inability the respiratory control system to maintain a level motor output cope with metabolic demands body. is also main determinant degree distress experienced by such patients. As progresses and patient increases, mechanical ventilation instituted help muscles heightened workload. While connected ventilator, physician's ability align rhythm machine patient's centers becomes primary rest accorded muscles. Problems alignment are manifested as trigger, double triggering, inflationary gas-flow that fails match inspiratory demands, inflation phase persists after have switched expiration. With recovery from disorders precipitated initial bout failure, attempts made discontinue ventilator (weaning). About 20% weaning fail, ultimately, because controller unable sustain this signaled rapid shallow breathing. Substantial advances in medical management requires assistance most likely result research yielding novel insights into operation system.
