When effective ventilation fails to establish a heart rate of greater than 60 bpm, cardiac compressions should be initiated to improve perfusion. The 2-thumb method is the most effective and least fatiguing technique. A ratio of 3 compressions to 1 breath is recommended to provide adequate ventilation, the most common cause of newborn cardiovascular collapse. Interruptions in compressions should be limited to not diminishing the perfusion generated. Oxygen (100%) is recommended during compressions and can be reduced once adequate heart rate and oxygen saturation are achieved. Limited clinical data are available to form newborn cardiac compression recommendations.
当有效的通气未能建立大于 60 次/分的心率时，应开始心脏按压以改善灌注。2 指法是最有效和最不累人的技术。推荐 3 次按压与 1 次呼吸的比例以提供足够的通气，这是新生儿心血管衰竭的最常见原因。应限制按压中断，以免减少产生的灌注。建议在按压时给予氧气（100%），一旦达到足够的心率和氧饱和度，即可减少氧气。目前可获得的新生儿心脏按压建议的临床数据有限。
