Dyspnea with lung sounds during sleep can be seen in respiratory diseases, such as asthma, acute attack of chronic bronchitis, and circulatory diseases such as acute left heart failure. 1. Bronchial asthma: due to the high excitability of the vagus nerve at night while sleeping, and the high airway reactivity of asthma patients, dyspnea and full lung rales can occur at night when sleeping and being stimulated by cold air. 2. Acute exacerbation of chronic bronchitis: when cold, smoking, exertion, etc., may lead to acute exacerbation of chronic bronchitis, causing increased airway secretions, bronchospasm, can appear when sleeping dyspnea with lung sound. 3. Acute left heart failure: If the patient has left heart insufficiency, when the heart load increases significantly for some reason, and the pulmonary circulation is stagnant, sudden dyspnea accompanied by lung sounds can also occur during sleep. Dyspnea with lung sounds during sleep may also be seen in other diseases, and it is important to consult a doctor in time to avoid delay and danger.
