Lung weights are often increased in drowning deaths as well as in other types of deaths. Lung weights may also vary with age, sex, and body weight. A variety of methods have been proposed to utilize lung weight data to assist with the diagnosis of drowning. The present study compared lung weight, lung-heart ratio (LH), and lung-body ratio (LB) between 50 consecutive drowning and 50 nonimmersion deaths in order to assess the accuracy in diagnosing drowning. Analysis revealed both LH and LB to be statistically higher in drowning deaths (P < 0.05), with LB being the most robust measurement. However, the overall diagnostic accuracies of lung weight, LH, and LB were poor to fair, and should therefore be used only in conjunction with the other diagnostic criteria.
在溺水死亡以及其他类型的死亡中，肺重量常常会增加。肺重量也可能因年龄、性别和体重而有所不同。已经提出了多种利用肺重量数据来辅助溺水诊断的方法。本研究比较了50例连续溺水死亡者和50例非浸没死亡者的肺重量、肺心比（LH）和肺体比（LB），以评估溺水诊断的准确性。分析显示，溺水死亡者的LH和LB在统计学上均较高（P < 0.05），其中LB是最可靠的测量指标。然而，肺重量、LH和LB的总体诊断准确性较差至中等，因此仅应与其他诊断标准结合使用。
