Blood oxygen saturation is an important clinical parameter, especially in postoperative hospitalized patients, monitored in clinical practice by arterial blood gas (ABG) and/or pulse oximetry that both are not suitable for a long-term continuous monitoring of patients during the entire hospital stay, or beyond. Technological advances developed recently for consumer-grade fitness trackers could-at least in theory-help to fill in this gap, but benchmarks on the applicability and accuracy of these technologies in hospitalized patients are currently lacking. We therefore conducted at the postanaesthesia care unit under controlled settings a prospective clinical trial with 201 patients, comparing in total >1,000 oxygen blood saturation measurements by fitness trackers of three brands with the ABG gold standard and with pulse oximetry. Our results suggest that, despite of an overall still tolerable measuring accuracy, comparatively high dropout rates severely limit the possibilities of employing fitness trackers, particularly during the immediate postoperative period of hospitalized patients.
血氧饱和度是一项重要的临床参数，尤其对于术后住院患者而言。在临床实践中，通常通过动脉血气分析（ABG）和/或脉搏血氧测定法来监测血氧饱和度，但这两种方法都不适用于在患者整个住院期间及出院后进行长期连续监测。最近为消费级健身追踪器开发的技术进步——至少在理论上——可能有助于填补这一空白，但目前缺乏关于这些技术在住院患者中的适用性和准确性的基准。因此，我们在麻醉后护理单元的可控环境下，对201例患者进行了一项前瞻性临床试验，总共比较了三个品牌健身追踪器的1000多次血氧饱和度测量结果与ABG金标准以及脉搏血氧测定法的结果。我们的结果表明，尽管总体测量精度仍可接受，但相对较高的失访率严重限制了使用健身追踪器的可能性，尤其是在住院患者术后即刻。
