为什么慢阻肺患者要持续低流量吸氧 薛晓明 山西省中医院
慢性阻塞性肺疾病患者病理生理最主要的是低氧血症，因为气道的痉挛、气道黏液的分泌、通气功能下降，弥散下降，就会出现氧气的不足，含氧量下降，就会出现低氧血症。不去纠正的话对人体是有损害的，累积到心脏引起心跳加速、心慌、心悸，严重者可以引起心律失常，那么呼吸系统就会引起咳嗽、咳痰、气喘，消化系统由于缺氧，导致胃肠道黏膜的瘀血出现胃脘部胀满，所以说低流量的吸氧对慢阻肺的患者至关重要。

Why do COPD patients need continuous low flow oxygen
Hypoxemia is the most important pathophysiology in COPD, Because of the spasm of the airway, the secretion of airway mucus and the decrease of ventilation function, Dispersion decreased, There will be a lack of oxygen, Oxygen content decreased, There will be hypoxemia. If we don't correct it, it will do harm to the human body, It accumulates to the heart to cause heart rate acceleration, palpitation and palpitation, Severe cases can cause arrhythmias, Then the respiratory system will cause coughing, expectoration and asthma, Because of lack of oxygen in the digestive system, It leads to congestion of gastrointestinal mucosa and fullness of epigastrium, Therefore, low flow oxygen inhalation is very important for COPD patients.
