呼吸衰竭(简称呼表)是呼吸功能严重损害,导致缺O~2或CO_2潴留,引起一系列的生理功能紊乱和代谢障碍的临床综合症。我省地处青藏高原大气压低,氧分压低,感染后缺氧加重,早期出现呼衰。由于胎儿型肺小动脉延续存在,有不同程度的肺动脉高压,右心负荷重,易出现心力衰竭,并发脑水肿,酸中毒等。因此保持呼吸道通畅,早期给氧解除支气管平滑肌和肺小动脉痉挛,控制心力衰竭,防治脑水肿。高原急性呼表时不能以平原呼衰的标准来衡量。
Respiratory failure (referred to as call table) is a serious respiratory dysfunction, leading to lack of O ~ 2 or CO2 retention, causing a series of physiological dysfunction and metabolic syndrome clinical syndrome. The province is located in the Qinghai-Tibet Plateau atmospheric pressure is low, partial pressure of oxygen, hypoxia increased after infection, early respiratory failure. Due to the persistence of fetal pulmonary arterioles, there are different degrees of pulmonary hypertension, right heart load, prone to heart failure, complicated by cerebral edema, acidosis and so on. Therefore, to maintain airway patency, early release of oxygen to bronchial smooth muscle and pulmonary arteriole spasm, control heart failure, prevention and treatment of cerebral edema. Altitude table call can not be an index of respiratory failure.
