With a new method for safe and complete evacuation of pericardial effusions it was possible to check the quantification of pericardial fluid is was possible to check the quantification of pericardial fluid by echocardiography. Using a formula based on the assumption that in systole the pericardial fluid is distributed equally around the contracting heart (like a coat enveloping a sphere), it was demonstrated that pericardial effusions ranging from 250 to 600 ml could be fairly accurately measured. Smaller effusions were not so readily determined. Effusions over 600 ml could be only roughly measured, usually being underestimated.
有了一种安全、完全排空心包积液的新方法，就可以通过超声心动图检查心包积液的定量情况。基于收缩期心包积液围绕收缩的心脏均匀分布（就像一件外套包裹着一个球体）这一假设的公式表明，250至600毫升的心包积液能够得到相当准确的测量。较小的积液不太容易确定。超过600毫升的积液只能大致测量，通常会被低估。
