The following stages in the test were analyzed: the pre-relaxing stage, the story telling stage, the anticipation of stress and the video exposition stage. Respiration signal is recorded during the whole test using a thoracic band. Power spectral density (PSD) of respiration is computed in running windows using a modification of Welch periodogram in which sufficiently peaked spectra are averaged. Then, respiratory frequency (FR) is estimated from the peaked-conditioned averaged spectra. Results show that respiratory rate is significantly (p < 0.05 according to the Friedman test) higher, while a measure of spectral peakness and the percentage of PSD used to compute (FR) is lower during stress stages than during relax. These results suggest that the respiration-related parameters have potential discrimination power for stress level assessment.2016http://zaguan.unizar.es/record/6310210.1109/CIC.2015.7411083http://zaguan.unizar.es/record/63102oai:zaguan.unizar.es:63102info:eu-repo/grantAgreement/ES/FIS/PI12-00514info:eu-repo/grantAgreement/ES/MINECO/TIN2014-5356-Rinfo:eu-repo/grantAgreement/ES/UZ/PIFUZ2011-TRCA-003info:eu-repo/grantAgreement/ES/UZ/UZ2014-TEC-01Computing in Cardiology 42 (2016), 1005-1008byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
