先判断有没有危险信号Check for danger signs first
突然或严重喘不过气、说不出完整句子、胸口紧重、疼痛延伸到手臂／背／颈／下颌、嘴唇发青或异常苍白、突然意识混乱，应立即到急诊；在马来西亚可拨打 999。不要等待线上回复。Sudden or severe difficulty breathing, being unable to speak in full sentences, a tight or heavy chest, pain spreading to the arm, back, neck or jaw, blue or unusually pale lips, or sudden confusion calls for emergency care. In Malaysia, call 999. Do not wait for an online reply.
若比平时更喘、咳血、单侧腿痛或肿胀、心悸，应尽快接受医疗评估。活动或平卧时越来越喘、脚踝肿胀，或咳嗽超过三周，也值得预约医生检查。Seek prompt medical assessment if you are more breathless than usual, cough blood, have pain or swelling in one leg, or notice palpitations. Breathlessness worsening with ordinary activity or when lying down, swollen ankles, or a cough lasting more than three weeks also warrants a medical appointment.
为什么会喘Why it can happen
常见原因包括哮喘、胸部感染、吸烟和体重相关负担；COPD、肺纤维化、心衰等也可能造成气短。焦虑或惊恐发作有时会引起气促，但在排除危险原因之前，不宜自行断定“只是紧张”。治疗取决于病因。Asthma, chest infections, smoking and weight-related strain are common causes. COPD, pulmonary fibrosis and heart failure can also cause breathlessness. Anxiety or panic can contribute, but it is unsafe to assume a new episode is “just stress” before serious causes are considered. Treatment depends on the cause.
“喘证”和“哮病”怎么理解How TCM terms fit in
中医“喘证”着重呼吸急促困难；“哮病”强调反复发作时的哮鸣声。它们是观察和辨证框架，不能与某一种现代肺病直接画等号，也无法代替血氧、影像或心肺检查。In TCM, chuan focuses on difficult, rapid breathing, while xiao highlights recurrent episodes with wheeze. These are ways to describe and assess a presentation, not one-to-one names for modern lung diseases or substitutes for oxygen measurement, imaging or heart and lung assessment.
就诊前记下什么What to note before a consultation
- 从什么时候开始喘：突然发生，还是数周至数月逐渐加重？When did it begin: suddenly, or gradually over weeks or months?
- 走路、上楼、平卧、夜间或接触烟雾时，有没有明显变化？Does it change with walking, stairs, lying flat, at night or after smoke exposure?
- 有没有发热、咳痰、胸痛、腿肿、咳血；目前用了哪些药物或吸入器？Is there fever, sputum, chest pain, leg swelling or blood in the sputum; what medicines or inhalers are you using?
医生会根据病史和检查决定是否需要量血氧、做胸部影像、心电图、血液检查或肺功能。不要自行停用已开立的吸入器或心脏药。A clinician may check oxygen level and decide whether chest imaging, an ECG, blood tests or lung function testing is needed. Do not stop prescribed inhalers or heart medicines on your own.
中医辅助照护的边界The place of supportive TCM care
病情稳定且原因明确后，注册中医师可帮助梳理睡眠、食欲、疲劳和生活节奏，与原有治疗配合。出现新发或加重的呼吸困难时，先由医疗系统排查原因；没有一种通用“补肺”方式适用于所有气喘。Once the condition is stable and its cause is understood, a registered TCM practitioner may help review sleep, appetite, fatigue and daily routines alongside existing treatment. New or worsening breathlessness needs medical assessment first; no single “lung-tonifying” approach fits every cause.
