A pig model of acute right ventricular afterload increase by hypoxic pulmonary vasoconstriction
Knai, Kathrine (Master thesis, 2017)Background: The aim of this study was to construct a non-invasive model for acute right ventricular afterload increase by hypoxic pulmonary vasoconstriction. Intact animal models are vital to improving our understanding ... -

Cardiac surgery does not lead to loss of oscillatory components in circulatory signals
Knai, Kathrine; Aadahl, Petter; Skjærvold, Nils Kristian (Peer reviewed; Journal article, 2020)The circulatory system is oscillatory in its nature. Oscillatory components linked to physiological processes and underlying regulatory mechanisms are identifiable in circulatory signals. Autonomic regulation is essential ... -
Oscillations in biological signal
Knai, Kathrine (Doctoral theses at NTNU;2020:302, Doctoral thesis, 2020)This thesis is a study of electrocardiography, blood pressure and glucose signals in the search for oscillatory physiological processes that are of importance for resilience and the development of disease. An oscillation ... -
Some oscillatory phenomena of blood glucose regulation: An exploratory pilot study in pigs
Skjaervold, Nils Kristian; Knai, Kathrine; Elvemo, Nicolas-Andreas L. (Journal article; Peer reviewed, 2018)It is well-known that blood glucose oscillates with a period of approximately 15 min (900 s) and exhibits an overall complex behaviour in intact organisms. This complexity is not thoroughly studied, and thus, we aimed to ...
