Validation of the Equivital (TM) EQO2+ LifeMonitor for Continuous Heart Rate Monitoring During Intermittent Military Relevant Tests of Physiological Limits
Abstract
We evaluated the efficacy of the EQ02+ for measuring heart rate (HR) in military personnel during intermittent tests of physiological limits. Twenty-seven US Army personnel (age, 24 + or - 6 years; height, 174 + or - 7 cm; body mass, 77 + or - 14 kg) were continuously monitored during two laboratory visits that included five activities: supine rest, incremental walk, incremental run, verification run, and load carriage. Heart rates recorded by the EQ02+ were compared against measurements from the chest-strap Polar H10 heart rate sensor. We examined the agreement between systems in the capability to measure continuous minute-by-minute, resting, and maximal HR. Heart rates continuously monitored by the EQ02+ and H10 systems over the laboratory visits were in close agreement (95% limits of agreement (LoA), [-7.5, 7.0 bpm]). The EQ02 and H10 systems provided similar measurements of resting HR (95% LoA, [-2.7, 3.7 bpm]) and maximal HR (95% LoA, [-7.9, 5.3 bpm]). The EQ02+ is an accurate body sensor for continuous HR monitoring of work/rest cycles across the physiological limits of cardiovascular function.
