BACKGROUND Asymptomatic postoperative atrial fibrillation (AF) may go undetected. As part of a multicenter observational trial designed to develop a risk prediction score for respiratory depression, the respiratory patterns of patients admitted to standard wards were continuously assessed with capnography and pulse oximetry. The monitor measured end-tidal carbon dioxide, respiratory rate, heart rate (HR), and oxyhemoglobin saturation. CASE REPORT Two men ages 75 and 72 experienced abrupt and variable postoperative changes in HR consistent with AF with rapid ventricular response, coinciding with an abnormal breathing pattern with apneic episodes. In both cases, the changes were not detected by routine clinical monitoring. CONCLUSIONS Continuous capnography identified respiratory distress in 2 patients who experienced symptoms of AF. Continuous monitoring devices can help health care providers minimize the risk of morbidity and mortality for patients at risk of respiratory depression.
无症状性术后心房颤动（AF）可能未被发现。作为一项旨在开发呼吸抑制风险预测评分的多中心观察性试验的一部分，使用呼气末二氧化碳、呼吸频率、心率（HR）和氧合血红蛋白饱和度连续评估入住标准病房的患者的呼吸模式。监护仪测量呼气末二氧化碳、呼吸频率、心率（HR）和氧合血红蛋白饱和度。
两名年龄分别为 75 岁和 72 岁的男性经历了与快速心室反应一致的 AF 的术后 HR 突然和多变的变化，同时伴有伴有呼吸暂停发作的异常呼吸模式。在两种情况下，常规临床监测均未检测到这些变化。
连续二氧化碳描记术在 2 例出现 AF 症状的患者中发现了呼吸窘迫。连续监测设备可以帮助医疗保健提供者降低有呼吸抑制风险的患者的发病率和死亡率风险。
