老年卧床患者长期卧床,咳嗽、咳痰无力,不能有效排出潴留在下呼吸道的痰液及分泌物时,会导致气道堵塞,血氧饱和度下降。虽然使用翻身扣背等物理方法及静脉,口服,雾化吸入化痰药物促进痰液排出,但由于患者体位与抗拒吸痰等原因,常导致吸痰管难进入下呼吸道,无法进入深部吸痰。由于吸痰本身是一种刺激,清醒的老年患者通常不愿意配合。不配合的患者牙关紧闭,同时口鼻吸痰的患者易引起黏膜损伤,出血等问题,改用口咽通气道吸痰可有效清除痰液及分泌 Bedridden elderly patients, cough, sputum weakness, can not effectively discharge retention in the lower respiratory tract sputum and secretions, can lead to airway obstruction, decreased oxygen saturation. Although the use of turning over buckles and other physical methods and intravenous, oral, aerosol inhalation of phlegm drugs to promote sputum discharge, but due to patient position and resistance to suction and other reasons, often lead to suction tube difficult access to the lower respiratory tract, unable to enter the deep suction . Because suctioning itself is an irritant, sober elderly patients are often unwilling to cooperate. Patients who do not cooperate with the teeth closed, while patients with oral and nasal suction sputum easily lead to mucosal injury, bleeding and other issues, switch to the oropharyngeal airway suction can be effective in removing sputum and secretion
