The LifeShirt is a novel ambulatory monitoring system that records cardiorespiratory measurements outside the laboratory. Validity and reliability of cardiorespiratory measurements recorded by the LifeShirt were assessed and two methods of calibrating the LifeShirt were compared. Participants performed an incremental treadmill test and a constant work rate test (65% peak oxygen uptake) on four occasions (>48 h apart) and wore the LifeShirt, COSMED system and Polar Sport Tester simultaneously. The LifeShirt was calibrated using two methods: comparison to a spirometer; and 800 ml fixed-volume bag. Ventilation, respiratory rate, expiratory time and heart rate recorded by the LifeShirt were compared to measurements recorded by laboratory equipment. Sixteen adults participated (6M:10 F); mean (SD) age 23.1 (2.9) years. Agreement between the LifeShirt and laboratory equipment was acceptable. Agreement for ventilation was improved by calibrating the LifeShirt using a spirometer. Reliability was similar for the LifeShirt and the laboratory equipment. This study suggests that the LifeShirt provides a valid and reliable method of ambulatory monitoring.
LifeShirt是一种新型的动态监测系统，可在实验室外记录心肺测量数据。对LifeShirt记录的心肺测量数据的有效性和可靠性进行了评估，并比较了两种校准LifeShirt的方法。参与者在四个不同时间（间隔>48小时）进行递增式跑步机测试和恒定工作率测试（峰值摄氧量的65%），并同时佩戴LifeShirt、COSMED系统和Polar Sport Tester。使用两种方法校准LifeShirt：与肺活量计比较；以及800毫升固定容积袋。将LifeShirt记录的通气、呼吸频率、呼气时间和心率与实验室设备记录的测量值进行比较。16名成年人参与研究（6名男性：10名女性）；平均（标准差）年龄23.1（2.9）岁。LifeShirt与实验室设备之间的一致性可以接受。使用肺活量计校准LifeShirt可提高通气的一致性。LifeShirt和实验室设备的可靠性相似。这项研究表明，LifeShirt提供了一种有效且可靠的动态监测方法。
