Low blood oxygen in the advanced stage of lung cancer needs timely consultation in hospital, actively searching for the cause of low oxygen, and then correcting the low oxygen according to the cause of the disease, and the treatment modes include oxygen inhalation, bronchial stenting, chest puncture and drainage, anticoagulation and so on.
Common causes of low oxygen in advanced stage of lung cancer include: tumor obstructing airway, combined pleural effusion, combined pulmonary embolism and so on.
1. If hypoxia is caused by tumor obstructing airway, the symptoms are: obvious dyspnea, audible wheezing sound in the inspiratory phase, and purplish lips when the symptoms are serious. It is difficult to correct hypoxia with oxygen therapy alone, and bronchoscopy is needed to clear the airway tumor, and bronchial stenting is necessary to correct hypoxia.
2. If the tumor is combined with pleural effusion, the symptoms are: chest pain, mostly related to breathing, aggravated by deep breathing or coughing, and dyspnea after activity. Thoracentesis is needed to drain the pleural fluid and reopen the lungs to correct the hypoxia.
3. In case of combined pulmonary embolism, typical symptoms are: hemoptysis, breathlessness after activity, chest pain, fainting. At this time, it is necessary to inhale oxygen and give low molecular anticoagulation or thrombolytic therapy in time.
Note: There are many reasons for low oxygen in late stage of lung cancer, so it is necessary to consult the hospital in time to find the cause of low oxygen and follow the doctor’s instruction for treatment.
