3、肤被烈日晒红并出现红肿、疼痛时，可用冷毛巾敷于患处，并适当涂一些滋润霜。若皮肤上已有水疱，千万不要挑破，应请医生处理，以免继发感染。溺水者获救后，应立即检查其呼吸、心跳。如呼吸停止，应马上做人工呼吸，先口对口连续吹入4口气，在5秒钟内观察其有无恢复自主呼吸，如无反应，应接着做人工呼吸，直至其恢复自主呼吸。如溺水者呼吸、心跳全无，应立即实施心肺复苏。(人工呼吸)首先，让伤病员仰卧，将其头后仰，确保呼吸道畅通。若其口内有血块、呕吐物、假牙等异物时，应尽快取出。随后作人工呼吸：每隔5秒吹一次气，反复进行。(胸外按压)先让患者躺在平整的地上，解开其上衣，将一只手的掌根置于其胸骨下三分之一的位置，另一只

4、手重叠压在手背上。两臂垂直，以上身的重量连续向下按压，频率每分钟至少100次。按压时用力适中，每次按压使胸骨下陷至少5厘米为度。手掌始终不要脱离按压部位。癫痫发作在救护车到来之前，可让患者的头侧向一边，以防止呕吐物窒息。随后，找一把金属调羹或牙刷等不易咬碎的东西塞进他的上下牙之间，防止舌咬伤。对于成年人，最好在硬东西上裹一层毛巾或手帕，以免咬掉牙齿立即关闭煤气，开窗透气。抢救者在进入溢满煤气的房间前，应先吸足一口气，然后用湿毛巾或手帕捂住口鼻，以防自己中毒。在煤气没有散尽前，不要开灯、按电铃、打电话或使用打火机、火柴等，以免引发爆炸。将中毒者移到通风的地方，松开中毒者的衣领、裤带。观察其意识、

5、心跳和呼吸情况。如已没有心跳和呼吸，立刻进行人工呼吸和胸外按压；如还有心跳、呼吸，应立即拨打急救电话，送医院进行高压氧治疗，以免留下后遗症。尽快找到电闸切断电源。如果暂时找不到电源，可就近找一样绝缘的东西，如木棍或塑料管子，挑开触电者与电源的接触，然后检查触电者的反应。如果发现其已经没有了心跳和呼吸，应立即就地对其进行人工呼吸和胸外按压，同时让别人拨打急救电话。确定有骨折后，一定要对伤肢(指)作固定再送医院，否则骨折断端异常活动，会加重损伤。可因地制宜用木板、木棍、树枝、竹竿、杂志等作为固定用的临时夹板。_ swell_ practical_ fist_ grab_ tight _ justi
