  2. 1. Titrating Open Lung PEEP in Acute Lung Injury : A clinical method based on changes in dynamic compliance

    Author : Fernando Suarez Sipmann; Göran Hedenstierna; Hans Hedenström; Stefan Lundin; Uppsala universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; PEEP; open lung; recruitment; dead space; electrical impedance tomography; ARDS.; Medicine; Medicin;

    Abstract : The recognition that supportive mechanical ventilation can also damage the lung, the so called ventilation induced lung injury (VILI), has revived the more than 40 year long debate on the optimal level of PEEP to be used. It is established that the prevention of VILI improves patient outcome and that PEEP exerts protective effects by preventing unstable diseased alveoli from collapsing. READ MORE

  4. 2. Minimally invasive cardiorespiratory monitoring and lung recruitment manoeuvres. Studies in animals and humans

    Author : Helena Odenstedt; Göteborgs universitet; []
    Keywords : Monitoring; cardiac output; lung volume; lung recruitment manoeuvre; regional ventilation; acute lung injury; bronchoalveolar lavage; endotoxin; cardiac tamponade;

    Abstract : Background: The maintenance of adequate oxygen delivery is essential to preserve organ function. The circulatory and respiratory systems interact closely to accomplish this. Optimising the function of these systems is of fundamental importance in critically ill patients. This requires adequate monitoring techniques. READ MORE

  5. 3. Transpulmonary pressure during mechanical ventilation

    Author : Christina Grivans; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical ventilation; Acute lung injury; Acute respiratory distress syndrome; Lung volume measurements; Electric Impedance diagnostic use; Lung elastance; Transpulmonary pressure; Esophageal pressure;

    Abstract : Background: Mechanical ventilation can aggravate lung injury by repetitive opening and closing of lung units, overdistention and undue pressure on pulmonary structures. Guidelines exist for lung protective ventilation, but individualized ventilator settings, based on partitioning of respiratory mechanics in pulmonary and chest wall complex components, would be beneficial.

  6. 4. Open lung concept in high risk anaesthesia : Optimizing mechanical ventilation in morbidly obese patients and during one lung ventilation with capnothorax

    Author : Henrik Reinius; Filip Fredén; Johan Petersson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesia; mechanical ventilation; atelectasis; morbidly obese; one-lung ventilation; PEEP; recruitment maneuver; spirometry; EIT; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : Formation of atelectasis, defined as reversible collapse of aerated lung, often occurs after induction of anaesthesia with mechanical ventilation. As a consequence, there is a risk for hypoxemia, altered hemodynamics and impaired respiratory system mechanics. READ MORE

  7. 5. Monitoring alveolar recruitment in the critically ill - Patient studies using electric impedance tomography and volume-dependent compliance

    Author : Karin Lowhagen; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALI; ARDS; compliance; end-expiratory lung volume; EELV; EIT; electric impedance tomography; lung recruitment; morbid obesity; PEEP; recruitment manoeuvre; regional ventilation; volume-dependent compliance;

    Abstract : Background: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are associated with a high mortality rate and poor long term outcome in terms of quality of life, for those who survive. Similarly, patients with morbid obesity are at risk for respiratory complications when subjected to anaesthesia and surgery. READ MORE
