Evaluating the significance of alarms at home in infants monitored for apnea/bradycardia depends on subjective parental observations. Retrospective analysis of 165 event recordings made during alarms in 90 monitored infants indicated that alarms were due to prolonged (greater than 15 s) apnea (6%), bradycardia (14%), shallow breathing (19%), mechanical malfunction (55%), or other causes (6%). Also, 68 infants had pneumograms. Of the 37 infants with an abnormal pneumogram, 14% had an abnormal event recording. Of the 31 infants with a normal pneumogram, 16% had an abnormal event recording. All monitors were discontinued without complication after a negative event recording. It may be concluded that (1) event recordings can document cardiorespiratory patterns during alarms, (2) the majority of alarms occurring at home are not significant, and (3) pneumograms do not appear to indicate which infants are at risk for a future significant alarm.
评估针对呼吸暂停/心动过缓进行监测的婴儿家中警报的重要性，依赖于家长的主观观察。对90名受监测婴儿警报期间的165次事件记录进行回顾性分析表明，警报原因包括长时间（超过15秒）呼吸暂停（6%）、心动过缓（14%）、呼吸浅慢（19%）、机械故障（55%）或其他原因（6%）。此外，68名婴儿有呼吸描记图。在37名呼吸描记图异常的婴儿中，14%事件记录异常。在31名呼吸描记图正常的婴儿中，16%事件记录异常。在事件记录为阴性后，所有监测器均无并发症地停用。可以得出结论：（1）事件记录可记录警报期间的心肺模式；（2）家中发生的大多数警报并不重要；（3）呼吸描记图似乎无法表明哪些婴儿未来有发生重要警报的风险。
