Cough with dyspnea can be caused by asthma, airway foreign body, pulmonary embolism, pleural effusion, pneumothorax and so on. 1. Asthma: Wheezing occurs during an acute asthma attack, and when the symptoms are severe, it may lead to airway spasm, resulting in dyspnea; bronchodilating drugs such as terbutaline and salbutamol are given to relieve the acute attack. 2. Airway foreign body: For example, if there is a tumor in the airway, choking and coughing when eating and blocking the airway, coughing with dyspnea may also occur, then it is necessary to consult the emergency room, and if necessary, tracheal intubation, tracheotomy and other methods to relieve the obstruction of the airway. 3. Pulmonary embolism: pulmonary embolism can also lead to airway obstruction, irritating dry cough, and even hemoptysis. At this time, it is necessary to promptly dissolve the thrombus. 4. Large amount of pleural effusion, pneumothorax can also lead to the above situation. If the above situations occur, it is necessary to consult a doctor in time to avoid delaying the treatment.
