Mild obstructive ventilation dysfunction is usually not serious. If uncontrolled, it is more serious when it affects normal life as the condition worsens. Obstructive dysfunction refers to the obstruction of the airway, resulting in ventilation dysfunction and difficulty in the exchange of gases between the outside world and the alveoli of the lungs, which may be characterized by chest tightness, shortness of breath, and dyspnea. Mild obstructive ventilation dysfunction is often characterized by insignificant shortness of breath after activity, chest tightness, coughing and wheezing, which are mostly tolerable, and lung function is usually satisfactory. It is not considered serious as it does not have a serious impact on daily life. If mild obstructive ventilation dysfunction is not effectively treated, the condition may aggravate, usually with obvious chest tightness, shortness of breath, dyspnea and other manifestations, which may affect daily life and reduce the quality of life, which is more serious at this time. It is recommended that patients suffering from mild obstructive ventilation dysfunction should go to the hospital in time and follow the doctor’s instructions for treatment to prevent the aggravation of the condition.
