在正常室温下,心脏骤停3秒钟之后,人就会因脑缺氧感到头晕;10至20秒钟后,人就会意识丧失;30至45秒钟后,瞳孔就会散大;1分钟后呼吸停止,大小便失禁;4分钟后脑细胞就会出现不可逆转的损害。由于心脏骤停,患者立刻失去知觉,已处于临床死亡阶段。一般人的最佳黄金抢救时间为4—6分钟,如果在4分钟之内得不到抢救,患者随即进入生物学死亡阶段,生还希望就极为渺茫。因此对于心脏骤停的病人,不要“争分夺秒”地去医院,应就地抢救。
Normal room temperature, cardiac arrest for 3 seconds, people will be due to cerebral hypoxia dizziness; 10 to 20 seconds, people will lose consciousness; 30 to 45 seconds, the pupil will be enlarged; After a few minutes of breathing stopped, incontinence; brain cells after 4 minutes there will be irreversible damage. As a result of cardiac arrest, the patient immediately loses consciousness and is at a clinical death. Most people’s best gold rescue time is 4-6 minutes, if not rescued within 4 minutes, the patient then entered the biological death stage, hope of surviving is extremely slim. Therefore, patients with cardiac arrest, do not “race against time” to go to the hospital, should be rescued on the spot.
