'Devil’s stairs', Poisson’s Statistics, and Patient Sorting via Variabilities for Oxygenation: All from Arterial Blood Gas Data

Autor: Yevhen Darnapuk, G. P. Chuiko, Yaroslav Krainyk, Anastasiia Diadenko, Olga Yaremchuk, Olga Dvornik

This report deals with arterial oxygen saturation (SaO2) for healthy adults. A comparably small data set (20 persons) holds 3-minute records of SaO2. The sample rate was 200 Hz. The charts have the looks of a “devil’s stairs.” A few (from 1 to

Autor: Yaroslav Kraynik, Yevhen Darnapuk, Olga Yaremchuk, G. P. Chuiko, Ruslan Haab, Olga Dvornik

Publikováno v: 2021 IEEE 12th International Conference on Electronics and Information Technologies (ELIT).

This report continues the series of researches on the data set for peripheral blood oxygenation. Here we confirm the separation of the healthy adults into three subgroups by variabilities of oxygenation. Two new measures (descriptors) of variability

Humans postural sways: non-Gauss, variability, and aging aspects of a data set mining

Autor: Olga Dvornik, Olga Yaremchuk, Yevhen Darnapuk, G. P. Chuiko, Yaroslav Krainyk

This report presents the results of data mining of a sample with two focus-groups. They have the same sizes: seven people into each one, random-wise picked up from the same data set. The trials of groups were idem. The postural swings, that is, the m

Computer Processing of Ambulatory Blood Pressure Monitoring as Multivariate Data

Autor: Yaroslav Krainyk, Olga Dvornik, Sergii Puzyrov, Olga Yaremchuk, Yevhen Darnapuk, G. P. Chuiko

Publikováno v: 2019 IEEE XVth International Conference on the Perspective Technologies and Methods in MEMS Design (MEMSTECH).

The blood pressure (systolic and diastolic) and heart rate of a patient were tested hourly during about 24-hours. Such a test is well-known in many clinics as ambulatory blood pressure monitoring. It is a standard for hypertension diagnostics. Usuall
