Microfilming of fetal monitoring records has, at our institution, been found to be a practical method for storage of recording papers from fetal monitoring. This system permits a reduction of the records by a factor of 20:1 and up to 7.64 hours of fetal monitroing records will fit into a 4 x 6 inch film jacket. This microfilm record can easily be placed into a patient's chart and can thus easily be retrieved.
在我们机构，已发现对胎儿监护记录进行缩微拍摄是存储胎儿监护记录纸的一种实用方法。该系统可将记录缩减20倍，一张4×6英寸的胶片夹可容纳长达7.64小时的胎儿监护记录。这种缩微胶片记录可轻松放入患者病历中，因此便于检索。
