When performing nebulization treatment, it is necessary for the person doing the nebulization to be awake. The main purpose of respiratory nebulization is to promote the expulsion of thick phlegm from one’s respiratory tract, so it is recommended that patients undergo nebulization when they are awake. If nebulization is done while sleeping, the sticky phlegm can easily be aspirated into the airway and digestive tract, which can lead to serious asphyxiation. Nebulization during waking hours can be combined with turning and back patting to better facilitate the expulsion of phlegm. Common nebulized medications include albuterol, budesonide, acetylcysteine, and ambroxol hydrochloride. Nebulization should be carried out under the guidance of healthcare professionals, and the medication used for nebulization should be in accordance with the doctor’s prescription. It is recommended to go to the suction department of the local hospital for consultation and professional advice.
