It includes a method for estimating respiratory rate based on statistical analysis of photoplethysmographic signals (human pulse wave), a method for selecting priority regions for estimating respiratory rate, and a criterion for determining the required bracelet tension during measurements. The application of the respiratory rate estimation method involves calculating the Correntropy spectral density of the pulse wave signal. A distinctive feature of the method is the use of an algorithm for selecting the priority empirical mode of the Hilbert-Huang decomposition, which is most closely related to the respiratory rate. Experimental verification of the method showed that the mean value of the absolute error for 58.8% of the sample of calculated respiratory rate values did not exceed 1 breath/min, and the 95% confidence interval for the mean absolute error of the entire sample was [0.72–2.2] breaths/min.</p></abstract><trans-abstract xml:lang="ru"><p>Предложен методический аппарат для создания сенсорных измерительных систем мониторинга частоты дыхания человека. Он включает метод оценки частоты дыхания на основе статистического анализа фотоплетизмографических сигналов (пульсовой волны человека), методику выбора приоритетных регионов для оценки частоты дыхания и критерий определения требуемого натяжения браслета при измерениях. Применение методики оценки частоты дыхания предполагает вычисление коррентропной спектральной плотности сигнала пульсовой волны. Отличительной особенностью методики является применение алгоритма выбора приоритетной эмпирической моды разложения Гильберта–Хуанга, в наибольшей степени связанной с частотой дыхания. Экспериментальная проверка методики показала, что среднее значение абсолютной погрешности для 58.8% выборки вычисленных значений частоты дыхания не превысило 1 вдох/мин, а 95% доверительный интервал для средней абсолютной погрешности всей выборки составил [0.72–2.2] вдохов/мин.</p></trans-abstract><kwd-group xml:lang="en"><kwd>photoplethysmogram pulse wave</kwd><kwd>respiratory motion frequency</kwd><kwd>optimal kernel Correntropy function</kwd><kwd>empirical Hilbert-Huang distribution</kwd><kwd>instantaneous Hilbert frequency</kwd><kwd>discrete Fourier transform</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>пульсовая волна фотоплетизмограммы</kwd><kwd>частота дыхательных движений</kwd><kwd>функция коррентропии с оптимальным ядром</kwd><kwd>эмпирическое распределение Гильберта–Хуанга</kwd><kwd>мгновенная частота Гильберта</kwd><kwd>дискретное преобразование Фурье</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Aificher E.
