Data Sheet 1_Monitoring military pilots with textile sensors: physiological responses and signal quality under extreme conditions.pdf

Therefore, continuous monitoring potentially provides critical insights about the impact of extreme condition exposure on the fitness to fly of military pilots.</p>Methods<p>We applied a textile-based monitoring system during training sessions with pilot aspirants to investigate the impact of hypobaric hypoxia and high G-force exposures on the signal quality obtained for a 1-lead electrocardiogram (ECG) and chest excursions.

The physiological variables considered were heart rate, heart rate variability, as well as respiratory frequency and respiratory amplitude.</p>Results<p>In general, 93.4% and 90.4% of the recorded ECG time segments during hypoxia and G-force exposure, respectively, were classified as plausible for further analysis. For respiratory data, 70.7% and 81.3% were classified as accurate for further data analysis and interpretation.</p>Discussion<p>Detailed information about signal quality was found to be critical for assessing physiological variables recorded in extreme conditions, including distinguishing between intra- and interpersonal variability.
