Patients with moderate emphysema need to undergo appropriate tests to assess the severity of their condition, such as pulmonary function tests, blood gas analysis and cardiac ultrasound. Patients are advised to quit smoking, adhere to respiratory function exercises, and give appropriate oxygen therapy. Patients can inhale long-acting bronchodilators, such as tiotropium bromide powder inhaler or combined with salmeterol ticapone powder inhaler, to improve airflow restriction and relieve chest tightness and shortness of breath after activities. If the ultrasound examination of the heart indicates the formation of pulmonary heart disease, it is more important to actively treat the chronic obstructive pulmonary disease, and if the right heart failure is combined, appropriate diuretic treatment can be given at this time.
