Performance of an Ambulatory Cardiorespiratory Monitoring System During Rest and Exercise

Abstract

The aim of this study was to evaluate the performance of a unique ambulatory system when used with physically active individuals. Seven physically active male volunteers were monitored during three different periods under varying exercise conditions. The monitoring sessions were approximately 18 hours in duration and consisted of no activity, sedentary activity, and vigorous exercise. After the monitoring sessions the system was downloaded and signal performance was analyzed for electrocardiogram (ECG), respiration rate (RESP), and blood oxygen saturation (SpO2). The results showed that signal performance across all activity levels and sensor types was able to provide an acceptable signal 84% of the time (ECG=96.9 +/- 3.0%, RESP=71.2 +/- 13.1%, and SpO2=83.7 +/- 13.8%). With the exception of the RESP signal, this instrument demonstrated that it could reliably provide the same accuracy in active persons as it does in sedentary persons.
