A variety of mechanical devices may be used to provide assistance when ventilation and cough are severely impaired by progressive respiratory weakness caused by neuromuscular disease. Traditionally, positive pressure ventilation via a tracheostomy has been used, but if upper airway function is adequate, a variety of noninvasive devices also may be considered. Although positive pressure ventilation is the preferred noninvasive mode for assisting ventilation, other modes may be selected depending on patient needs, preferences, and physical characteristics.
当神经肌肉疾病导致进行性呼吸肌无力，使通气和咳嗽严重受损时，可使用多种机械装置来提供辅助。传统上，一直采用经气管造口的正压通气，但如果上呼吸道功能良好，也可考虑使用多种无创装置。尽管正压通气是辅助通气的首选无创模式，但也可根据患者的需求、偏好和身体特征选择其他模式。
