Beat-by-beat cardiac power: Minimally invasive assessment of overall cardiovascular performance
Rimehaug, Audun Eskeland (Doctoral theses at NTNU;2016:316, Doctoral thesis, 2016) -
Cardiac power integral: a new method for monitoring cardiovascular performance
Rimehaug, Audun Eskeland; Lyng, Oddveig; Nordhaug, Dag Ole; Løvstakken, Lasse; Aadahl, Petter; Kirkeby-Garstad, Idar (Journal article; Peer reviewed, 2013)Cardiac power (PWR) is the continuous product of flow and pressure in the proximal aorta. Our aim was to validate the PWR integral as a marker of left ventricular energy transfer to the aorta, by comparing it to stroke ... -
Cardiac power parameters during hypovolemia, induced by the lower body negative pressure technique, in healthy volunteers
Rimehaug, Audun Eskeland; Hoff, Ingrid E Taraldsrud; Høiseth, Lars Øivind; Hisdal, Jonny; Aadahl, Petter; Kirkeby-Garstad, Idar (Journal article; Peer reviewed, 2016)Background: Changes in cardiac power parameters incorporate changes in both aortic flow and blood pressure. We hypothesized that dynamic and non-dynamic cardiac power parameters would track hypovolemia better than equivalent ... -
Minimally invasive beat-by-beat monitoring of cardiac power in normal hearts and during acute ventricular dysfunction
Rimehaug, Audun Eskeland; Skogvoll, Eirik; Aadahl, Petter; Lyng, Oddveig; Nordhaug, Dag Ole; Løvstakken, Lasse; Kirkeby-Garstad, Idar (Journal article; Peer reviewed, 2016)Cardiac power, the product of aortic flow and blood pressure, appears to be a fundamental cardiovascular parameter. The simplified version named cardiac power output (CPO), calculated as the product of cardiac output (CO) ... -
Post Cardiac Surgery Stunning Reduces Stroke Work, but Leaves Cardiac Power Output Unchanged in Patients with Normal Ejection Fraction
Tannvik, Tomas Dybos; Rimehaug, Audun Eskeland; Skjaervold, Nils Kristian; Kirkeby-Garstad, Idar (Journal article; Peer reviewed, 2018)This study assesses positional changes in cardiac power output and stroke work compared to classic haemodynamic variables, measured before and after elective coronary artery bypass graft surgery. The hypothesis was that ...
