Cement ash inhalation into the lungs, depending mainly on the amount inhaled, can be cleared by voluntary coughing or alveolar lavage. If the ash is inhaled in a small amount and there are no serious symptoms, it can often be expelled from the lungs by coughing on its own. Moreover, after inhaling the ash, the human body will have a natural rejection reaction, resulting in a persistent cough, which will expel the ash and other particles along with the sputum. However, if the amount of cement ash inhaled is relatively large, it is often necessary to take alveolar lavage, which is a procedure in which a bronchoscope is inserted into the patient’s bronchial tubes, and the alveolar lavage is carried out through endoscopic observation and injection of a cleaning solution, which can also expel the cement ash from the lungs. Cement ash inhalation in the lungs, if it causes serious discomfort, should be timely to the hospital, with the doctor to take treatment, so as not to delay the condition to increase the difficulty of treatment.
