目前认为,吸气时出现的所谓“湿性啰音”,不如叫吸气性爆裂音(Inspiratory Crackles)更为确切。过去认为它是由于吸气或呼气时气流冲击支气管内的分泌物而发出的气泡音或水泡音。1967年Forgacs氏指出,这种附加音不是吸入气体作用于分泌物而发出的气泡音。因为气道内的分泌物(特别在较大的气道内),由于其粘稠度和表面张力,气流通过时不可能发出气泡音。目前大多数人倾向于认为,这种 It is currently believed that the so-called “wet rales” that appear during inspiration are not as specific as Inspiratory Crackles. In the past, it was thought to be a bubble sound or blisters sound caused by the air current impacting bronchial secretions on inhalation or expiration. Forgacs, 1967, pointed out that this additional note is not a bubble tone emitted by inhalation of gas acting on secretions. Because of the secretions in the airways (especially in larger airways), it is unlikely that the air bubbles will be emitted due to their consistency and surface tension. At present, most people tend to think that this
