急危重症患者抢效,保持呼吸的道通畅是重要原则。大量的临床实践证明,对于心跳呼吸停止及其严重缺氧的呼吸衰竭患者,单纯依靠鼻导管吸氧,面罩吸氧或口对口呼吸不可能纠正缺氧状态,必须及时进行气管内插管,经口或鼻气管建立人工呼吸通道,才是行之有效的方法。 Emergency critically ill patients rush to maintain the patency of the breath is an important principle. A large number of clinical practice has proved that for patients with heart failure and respiratory failure due to severe hypoxia, it is impossible to correct hypoxia simply by nasal catheter oxygen, mask oxygen or mouth-to-mouth respiration. Endotracheal intubation must be performed in time. The establishment of artificial respiration channels in the mouth or nasal trachea is an effective method.
