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 ... -
Automated blood glucose control: Development and Testing of an Artificial Endocrine Pancreas Using a Novel Intravascular Glucose Monitor and a New Approach to Insulin Pharmacology
Skjærvold, Nils Kristian (Doktoravhandlinger ved NTNU, 1503-8181; 2012:275, Doctoral thesis, 2012)This thesis describes the stepwise development and testing of the components of a novel artificial endocrine pancreas, consisting of a continuous glucose monitor, an insulin infusion device and a control algorithm. The ... -
Blood glucose management in the critically ill : perception and clinical practice in the ICU
Bø, Hanne (Master thesis, 2017)Background Contradictory findings from multiple studies on blood glucose management in the ICU and the absence of clear international guidelines leads to varying perceptions and clinical practice among clinicians. ... -
Cardiac power output og stroke work postoperativt etter hjertekirurgi : energileveranse fra hjertet det første døgnet postoperativt etter hjertekirurgi
Shvets, Ksenia (Master thesis, 2016)Introduksjon Cardiac power output (CPO) er tidsintegralet av hjerteminutt-‐volumet (CO) og middelarterie-‐ trykk (MAP) og er et uttrykk for den samlede energileveransen fra hjertet. Stroke work (SW) er energileveransen ... -
Circulatory oscillations in post cardiac surgery patients
Axelsson, Fredrik Einar Tobias; Lio, Bjørn Gardsjord (Master thesis, 2016)The aim of this study was to monitor, analyse and compare circulatory oscillations in blood pressure (BP) and heart rate (HR) in ten patients undergoing elective CABG surgery. The subjects were monitored with continuous ... -
Distortion of complexity in oscillations of arterial blood pressure, due to aging
Orten, Erik Norvald (Master thesis, 2017)Age both influences and limits an individual’s capability to withstand adverse circulatory distress such as sepsis or cardiac events, and is by itself considered a major risk factor for hypertension. The aim of this study ... -
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 ... -
Prelimenary preprocessing of ECG-signals for use in multivariate analysis
Wedeld, Mikael Dyb (Master thesis, 2018)In order to lay the framework for a possible multivariate heart model, a set of methods for preprocessing an electrocardiogram signal has been created. A normalized least mean square adaptive filter was created for filtering ... -
Preprocessing of Arterial Pressure Waves for Later Use in Modeling of Individual Heartbeats
Danielsen, Tina (Master thesis, 2018)Arterial pressure waves (APW) contain essential information, where the different shape of the waveform can indicate illness or essential information. Furthermore, there can be differences between subject independent of ... -
Variasjon i bruk av arteriekateter og venekateter i Noreg og Europa
Velle, Martinus (Master thesis, 2017)Bakgrunn: Venekateter og arteriekateter er mykje brukt på intensivpasientar. Særleg bruk av arteriekateter er lite rapportert. Metode: Det er gjennomført ein eindags prevalensstudie på kateterbruk i intensivavdelingar i ...
