1. 1. Intestinal effects of lung recruitment maneuvers

   Författare :Jonas Claesson; Ola Winsö; Stefan Lehtipalo; Conny Arnerlöv; Björn Biber; Göran Hedenstierna; Petter Aadahl; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute lung injury; oleic acid lung injury; ischemia; reperfusion injury; swine; mechanical ventilation; lung recruitment; splanchnic circulation; laser Doppler flowmetry; tissue oxygen tension; microdialysis; lactate; glycerol; Anaesthetics and intensive care; Anestesiologi och intensivvård; lungmedicin; Lung Medicine;

   Sammanfattning : Background and aims: Lung recruitment maneuvers (brief episodes of high airway pressure) are a modern treatment alternative to achieve open lung conditions under mechanical ventilation of patients with acute lung injury. It is well known that positive pressure ventilation with high airway pressures cause negative circulatory effects, and that the effects on regional vascular beds can be even more pronounced than the systemic effects.

3. 2. FRC in acute lung injury. Experimental and clinical studies

   Författare :Christian Rylander; Göteborgs universitet; []
   Nyckelord :Airway obstruction; Acute lung injury; Acute respiratory distress syndrome; Attenuation; Computed tomography; End-expiratory lung volume; Functional residual capacity; Gas dilution; Hounsfield unit; Lung volume; Oleic acid; Recruitment; Time constant;

   Sammanfattning : Respiratory failure due to acute lung injury (ALI) of diffuse inflammatory origin is a major cause of respiratory failure treated in intensive care units. In ALI, FRC is reduced by various mechanisms associated with hypoxemia and consolidation of the lung. LÄS MER

4. 3. Artificial Neural Networks (ANN) in the Assessment of Respiratory Mechanics

   Författare :Gaetano Perchiazzi; Göran Hedenstierna; Björn Jonson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; artificial neural networks; respiratory system compliance; respiratory system resistance; respiratory system time constant; intrinsic positive end expiratory pressure; PEEPi; animal model; acute lung injury; oleic acid; Otis model; Fysiologi; Physiology; Fysiologi;

   Sammanfattning : The aim of this thesis was to test the capability of Artificial Neural Networks (ANN) to estimate respiratory mechanics during mechanical ventilation (MV). ANNs are universal function approximators and can extract information from complex signals. LÄS MER

5. 4. Inhaled Nitric Oxide Therapy : Non-response and Rebound Response

   Författare :Luni Chen; Eddie Weitzberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; nitric oxide inhalation; rebound response; non-response; endothelin-1; COX inhibitor; prostaglandin; ARDS; endotoxin; oleic acid; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; Clinical Physiology; klinisk fysiologi;

   Sammanfattning : Therapeutic inhaled nitric oxide (INO) has proved beneficial in patients with pulmonary hypertension. However, around 30-40% of the patients are non-responders to this therapy, and a life-threatening rebound response may occur during attempts to withdraw INO. LÄS MER

7. 5. Airway pressure release ventilation : A systematic experimental approach

   Författare :Peter Neumann; Uppsala universitet; []
   Nyckelord :Medical sciences; APRV; CPAP; atelectasis; recruitment; PEEP; inverse ratio ventilation; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

   Sammanfattning : Airway pressure release ventilation (APRV) is a ventilatory mode which allows unrestrictedspontaneous breathing (SB) throughout the ventilatory cycle. If SB is insufficient, mechanicalventilatory support is achieved by brief periodic decreases of the airway pressure below the CPAPlevel. LÄS MER
