Postoperative monitoring of cardiac operated patients requires appropriately functioning monitor alarms as well as intensive nursing activity. The limit alarms can be used for detection of life-threatening situations and monitoring of physiological changes in the patient's state. We studied the significance and the frequency of audible alarms during the postoperative intensive care of ten cardiac patients. Of 1307 occasions when such an alarm was activated during the study period of approximately 26 hours per patient, only 139 (10.6%) were significant. The highest proportion of significant audible limit alarms was found during the immediate postoperative period. Heart rate alarms were more reliable than alarms of the other parameters monitored in the study. Possibilities for improving the physiological monitoring and alarm system are discussed.
心脏手术患者的术后监测需要功能正常的监测警报器以及密集的护理活动。极限警报可用于检测危及生命的情况并监测患者状态的生理变化。我们研究了十名心脏患者术后重症监护期间可听警报的意义和频率。在每位患者约26小时的研究期间，此类警报被触发的1307次情况中，只有139次（10.6%）具有重要意义。在术后即刻期间发现的重要可听极限警报比例最高。心率警报比研究中监测的其他参数的警报更可靠。文中还讨论了改进生理监测和警报系统的可能性。
