1 呼吸功能的判断呼吸骤停的早期征兆包括:1呼吸频率增加、呼吸困难和/或两侧呼吸音减低;2神志改变或对疼痛反应能力减退;3骨骼肌张力减退;4中央型紫绀。正常呼吸频率随年龄而减少:新生儿40次/分;1岁24次/分;18岁时18次/分。潮气量则基本不变,6～8ml/kg。异常呼吸可分为呼吸急
1 respiratory function to determine the early signs of respiratory arrest include: 1 increased respiratory rate, dyspnea and / or bilateral breath sounds decreased; 2 conscious change or diminished ability to respond to pain; 3 skeletal muscle tension decreased; 4 central cyanosis. Normal respiratory rate decreases with age: 40 newborns / min; 1 year old 24 beats / min; 18 years old 18 beats / min. Tidal volume is basically unchanged, 6 ~ 8ml / kg. Abnormal breathing can be divided into respiratory urgency
