    Abstract : Breath gas analysis is a promising approach for non-invasive medical diagnostics and physiological monitoring. Real-time, breath-cycle resolved biomarker detection facilitates data interpretation and has the potential to improve the diagnostic value of breath tests as exhalation profiles carry spatiotemporal information about biomarker origin and gas exchange in the respiratory tract.

  2. 2. Influence of tidal volume on pulmonary gas exchange during general anaesthesia

    Author : Bruno Enekvist; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesia; sevoflurane; cardiac output; functional residual capacity; pulmonary gas exchange;

    Abstract : Background and objective: General anaesthesia impairs respiratory function. The present studies were performed to compare arterial concentration of sevoflurane, oxygen and carbon dioxide in normal and overweight patients ventilated with increased tidal volume (VT), or normal tidal volume with and without PEEP.

  3. 3. Gas Exchange in the Normal Lung : Experimental studies on the effects of positive end-expiratory pressure and body position

    Author : Mats J. Johansson; Sten Walther; Gunnar Nicolaysen; John-Peder Escobar Kvitting; Stefan Lundin; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : BACKGROUND: The principal function of the lung is gas exchange requiring adequate ventilation and perfusion at the level of the alveoli. The efficiency of gas exchange is depending on the distributions of regional ventilation (V) and pulmonary blood flow (Q) and their correlation. READ MORE

  4. 4. Surgically corrected univentricular hearts. Anatomical, haemodynamic and functional status at a long-term follow-up

    Author : Eva Strömvall-Larsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : cavopulmonary connections; univentricular hearts; long-term follow-up; pulmonary; arteriovenous malformations; lung volumes; cardiac output; pulmonary gas exchange and maximal; exercise studies;

    Abstract : The Fontan operation and its modifications are applied to a large spectrum of congenital heart defectswith univentricular physiology. The Fontan circulation is characterised by a reduced, non-pulsatilepulmonary blood flow and the elevated central venous pressure is the main driving force for thepulmonary blood flow. READ MORE
