氧气疗法(简称氧疗)是儿科临床的重要治疗措施,正确的应用可有效地提高血氧分压改善机体的缺氧,而应用不当不仅影响其效果,还可能带来各种危害。现将小儿氧疗的有关问题介绍如下。 一、氧疗的指证 凡有低氧血症或有组织缺氧者均为氧疗的适应证,但由于机体具有一定的代偿能力和适应能力,氧疗在临床上仅用于缺氧较显著及有临床症状者。其临床指征为:(1)紫绀;(2)无其他原因的心率加快伴烦躁不安;(3)呼吸异常;包括呼吸过快或过缓、呼吸费力、频繁呼吸暂停等;(4)各种原因引起的休克、心力衰竭、颅高压综合征;(5)严重高热或有意识障碍;(6)严重贫血。血气指标:(1)
Oxygen therapy (referred to as oxygen therapy) is an important pediatric clinical treatment, the correct application can effectively improve the partial pressure of oxygen to improve the body’s hypoxia, and improper application not only affects its effectiveness, it may also bring a variety of hazards. Now the pediatric oxygen therapy related issues are as follows. First, the indication of oxygen therapy where hypoxemia or hypoxia are indications of oxygen therapy, but due to the body has a compensatory ability and ability to adapt, oxygen therapy is only used in clinical hypoxia than Significant and clinical symptoms. The clinical indications are as follows: (1) cyanosis; (2) heart rate acceleration and restlessness without other causes; (3) abnormal breathing; including excessive or slow breathing, respiratory effort, frequent apnea and the like; Causes of shock, heart failure, intracranial hypertension syndrome; (5) Severe fever or disturbance of consciousness; (6) Severe anemia.
