Rapid relief of respiratory distress requires professional technical support and equipment, so the first thing to do after a patient around respiratory distress is to call 120 emergency urgently. The principle of dealing with respiratory distress is firstly to keep the respiratory tract unobstructed, to administer oxygen in time and to control the state of hypoxia; secondly, to deal effectively with the cause of the disease. Specific methods are analyzed as follows: 1, unblock the respiratory channel: firstly, immediately clear the patient’s mouth, pharynx, throat and secretions in the respiratory tract, if the patient’s sputum excretion function is normal, pay attention to airway humidification and sputum dilution, and use expectorants appropriately; if the patient’s sputum excretion function is not good, artificially assisted methods can be used to give sputum excretion; 2, oxygen therapy: patients with respiratory distress should be given short-term high-flow oxygen, so that oxygen saturation is maintained at greater than or equal to 90% without oxygen toxicity; 3, mechanical ventilation: mechanical ventilation is currently the most effective method to treat respiratory distress. When the above methods are ineffective, the patient can be given an artificial airway for assisted ventilation to improve the symptoms of hypoxia and carbon dioxide retention; 4, treatment for the cause: after the patient’s condition is stabilized, different treatment measures will be taken according to different conditions to avoid the occurrence of respiratory distress again. If pneumothorax or fluid chest is present, thoracentesis and fluid extraction are required; if bronchial asthma attack or acute attack of chronic obstructive pulmonary disease is present, inhaled bronchodilators (salbutamol aerosol) or hormone therapy is required; if heart failure is present, cardiac diuretic and vasodilator therapy is required.
