  2. 6. 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.

    Abstract : The history of surgery is nearly as old as the human race. Control of wound infection has always been an essential part of any surgical procedure, and is still an important challenge in hospital operating rooms today. For patients undergoing surgery there is always a risk that they will develop some kind of postoperative complication. READ MORE

  5. 8. Minimal volume ventilation in lung injury : With special reference to apnea and buffer treatment

    Author : Staffan Höstman; Anders Larsson; Hans Hjelmqvist; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VILI; THAM; buffers; apneic oxygenation; respiratory acidosis; hypercapnia; low volume ventilation; mechanical ventilation; ultra-protective ventilation; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : A fairly large portion of patients receiving surgical or intensive care will need mechanical ventilation at some point. The potential ventilator-induced lung injury (VILI) is thus of interest. One of the main causal factors in VILI is the cyclic energy shifts, i.e. READ MORE

  6. 9. Investigations of Flow Patterns in Ventilated Rooms Using Particle Image Velocimetry : Applications in a Scaled Room with Rapidly Varying Inflow and over a Wall-Mounted Radiator

    Abstract : This thesis introduces and describes a new experimental setup for examining the effects of pulsating inflow to a ventilated enclosure. The study aimed to test the hypothesis that a pulsating inflow has potential to improve ventilation quality by reducing the stagnation zones through enhanced mixing. READ MORE

  7. 10. New methods for optimization of mechanical ventilation

    Author : Peter Kostic; Peter Frykholm; Anders Larsson; Johan Petersson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mechanical ventilation; optoelectronic plethysmography; forced oscillation technique; laser interferometry; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : Mechanical ventilation saves lives, but it is an intervention fraught with the potential for serious complications. Prevention of these complications has become the focus of research and critical care in the last twenty years. READ MORE
