Shortness of breath and chest tightness always want to take a deep breath is a manifestation of dyspnea, if it is a physiological phenomenon, no special treatment. If it is caused by asthma, heart failure and other diseases, we need to take general treatment, medication and surgical treatment for the cause. 1. Physiological phenomenon: when the human body stays in an environment with poor air circulation for a long time, dyspnea is easy to appear. Secondly, it may also be caused by excessive mental stress and emotional stress, which generally requires no special treatment, timely departure from the closed environment, emotional adjustment, self-relief, and self-relief within a short period of time. 2. Asthma: common symptoms include wheezing, shortness of breath, dyspnea, chest tightness and so on. Patients need to take oxygen or mechanical ventilation to keep the airway open, but also can follow the doctor’s instructions to apply albuterol, terbutaline and other β2 agonists, doxophylline, aminophylline and other theophyllines, as well as ipratropium bromide and tiotropium bromide and other anticholinergic drugs. For patients with recurrent disease after drug treatment, surgical treatment such as bronchial thermoplasty should be considered. 3. Heart failure: typical symptoms include dyspnea, palpitation and weakness. Patients need to pay attention to rest, cooperate with the doctor to inhale oxygen, and maintain emotional stability. At the same time, they need to follow the doctor’s instructions to apply angiotensin-converting enzyme inhibitors such as captopril and enalapril, diuretics such as furosemide and hydrochlorothiazide, as well as beta-blockers such as propranolol and metoprolol, and cardiac stimulants such as digoxin and milrinone. Surgical treatments such as cardiac resynchronization therapy, implantable cardioverter-defibrillators, and heart transplants are required for patients with severe conditions. If the shortness of breath and chest tightness always want to take a deep breath to exclude the physiological phenomenon, you need to go to the hospital in time, cooperate with the doctor to treat the original disease.
