  2. 11. Computational modelling of blood flow in medical assist devices

    Author : Francesco Fiusco; Lisa Prahl Wittberg; Lars Mikael Broman; Anders Dahlkild; David Ku; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computational fluid dynamics; haemodynamics; platelet activation; thrombogenicity; haemolysis; extracorporeal membrane oxygenation; sensitivity; Teknisk mekanik; Engineering Mechanics;

    Abstract : Extracorporeal membrane oxygenation (ECMO) is a life-saving support treat-ment in case of pulmonary and/or cardiac failure. An artificial extracorporealcircuit is used to offload the function of lungs and/or heart. READ MORE

  4. 12. Synchronized delivery of inspired nitric oxide : Effects on oxygenation and pulmonary tension during artificial ventilation

    Author : Erkki Heinonen; Tim Higenbottam; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; nitric oxide; pulsed administration; pulmonary hypertension; oxygenation; equine; Cellbiologi; Cell biology; Cellbiologi; Physiology; fysiologi;

    Abstract : Nitric oxide (NO) is a mediator of vascular smooth muscle tension that metabolises rapidly in blood. NO delivered by inhalation can therefore be used as a selective pulmonary vasodilator to relieve pulmonary hypertension or to improve oxygenation with no systemic effects. READ MORE

  5. 13. Hemodynamic Effects of Lung Function Optimization in Experimental Acute Respiratory Distress Syndrome

    Author : Arnoldo Santos; Anders Larsson; Fernando Suarez-Sipmann; John Marini; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute respiratory distress syndrome; Lung protective ventilation; Mechanical ventilation; Open lung approach; Pulmonary heart disease; Pulmonary vascular mechanics; Pulmonary vascular dysfunction; Pulse wave analysis; Right ventricular dysfunction; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care; Fysiologi; Physiology;

    Abstract : Acute Respiratory Distress Syndrome (ARDS) is a severe pulmonary inflammation affecting thousands of patients every year in Sweden and has a mortality of 30-50%. Mechanical ventilation (MV) is usually necessary, but could per se augment the inflammation and contribute to mortality. READ MORE

  6. 14. Hypoxic pulmonary vasoconstriction and nitric oxide

    Author : Kristina Hambraeus Jonzon; Karolinska Institutet; Karolinska Institutet; []
    Keywords : hypoxia; pulmonary vasoconstriction; regional pulmonary bloodflow; stimulus-response; nitric oxide; blood-borne distant effects; nitric oxide synthase activity; inhaled; exhaled; non-enzymatic;

    Abstract : Hypoxia causes pulmonary vasoconstriction (HPV), improving oxygenation by redistribution of the pulmonary blood flow to better oxygenated lung regions. HPV is intrinsic to the pulmonary vascular smooth muscle cell, but can be modulated by several vasoactive substances, as for example endothelium derived nitric oxide (NO) and endothelin-1 (ET-1).

  7. 15. In the hands of ohm : hemodynamic aspects in pulmonary hypertension

    Author : Erik Tossavainen; Per Lindqvist; Michael Henein; Stefan Söderberg; Peter Eriksson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kardiologi; Cardiology;

    Abstract : Congestive heart failure (CHF) is one of the most challenging diseases in terms of health care demand and mortality, in the western world. Despite major breakthroughs in the fields of diagnosis and treatment over the three last decades, the management of CHF still remains challenging. READ MORE
