Recent evidence suggests that the fifth Korotkoff sound (K5) is a much more reliable point of measurement to determine diastolic blood pressure in pregnant women than the fourth one (K4). The guidelines for obstetricians and midwives should be corrected without delay to reflect this new knowledge. In non-pregnant people K5 already is the point of reference.
最近的证据表明，对于确定孕妇的舒张压而言，第五柯氏音（K5）比第四柯氏音（K4）是更可靠的测量点。应立即纠正产科医生和助产士的指南，以反映这一新知识。在非孕妇中，K5已经是参考点。
