  1. 6. Intelligent Driver Mental State Monitoring System Using Physiological Sensor Signals

    Författare :Shaibal Barua; Peter Funk; Shahina Begum; Mobyen Uddin Ahmed; Christer Ahlström; Jose Peña; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Artificial Intelligent; Intelligent systems; Physiological signal; Driver monitoring; Computer Science; datavetenskap;

    Sammanfattning : Driving a vehicle involves a series of events, which are related to and evolve with the mental state (such as sleepiness, mental load, and stress) of the driv- er. These states are also identified as causal factors of critical situations that can lead to road accidents and vehicle crashes. LÄS MER

  3. 7. Arterial pulse wave analysis. With special reference to vasoactive and anaesthetic drugs and to heart lung interactions

    Författare :Staffan Söderström; Göteborgs universitet; []
    Nyckelord :pulse; blood pressure physiology; hypertension; aged; vasodilation; ventricular function; left; nitroglycerin; coronary disease; artificial respiration; fentanyl.;

    Sammanfattning : In the young systolic arterial pressures (SAP) are higher in the radial artery than in the proximal aorta. Due to increased large artery stiffness and early pulse wave reflection aortic SAP increases more with age than peripheral SAP. LÄS MER

  4. 8. Computer simulation - a tool for optimisation of ventilator setting in critical lung disease

    Författare :Leif Uttman; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adult · Swine; Computer Simulation ·Artificial Respiration ·Pulmonary Gas Exchange · Respiratory Dead Space · Respiratory Mechanics · Respiratory Distress Syndrome; Physiology; Fysiologi;

    Sammanfattning : Increasing attention is paid to mechanical ventilation as one cause behind aggravation of lung injury. Lung protective ventilation can be achieved e.g. by minimising tidal lung collapse and re-expansion and by the use of small tidal volume allowing some degree of permissive hypercapnia. LÄS MER

  5. 9. Surfactant metabolism in the newborn : the impact of ventilation strategy and lung disease

    Författare :Kajsa Bohlin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Surface active agents; pulmonary surfactant; respiratory distress syndrome; stable isotope; artificial respiration; continuous positive airway pressure; metabolism; rabbit; compliance; preterm; newborn;

    Sammanfattning : Developmental deficiency in pulmonary surfactant leads to respiratory distress syndrome (RDS) in preterm infants, but all newborns may have impaired surfactant metabolism secondary to lung disease or ventilator induced lung injury. Exogenous surfactant treatment is usually administered in conjunction with mechanical ventilation. LÄS MER

  7. 10. Inverse ration ventilation : experimental studies on pulmonary integrity and gas exchange

    Författare :Ulf Ludwigs; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :respiration; artificial gas exchange lung function acute respiratory distress syndromeacute lung injury inverse ratio ventilation ventilator induced lung injury intrinsic PEEP lungclearance;

    Sammanfattning : In this thesis, pulmonary and circulatory effects of inverse ratio ventilation (IRV) have been studied experimentally. Comparisons have been made between volume and pressure controlled IRV and conventional ventilation under conditions of equal minute ventilation and end-expiratory alveolar pressure levels. LÄS MER
