  2. 1. The dynostatic algorithm in adult and paediatric respiratory monitoring

    Author : Sören Söndergaard; Göteborgs universitet; []
    Keywords : monitoring; respiratory mechanics; lung model; fibre optic pressure measurement; alveolar pressure; dynostatic algorithm;

    Abstract : Introduction: Positive pressure ventilation carries a risk of aggravating systemic and lung disease. Monitoring of ventilatory pressure and volume is important to minimize this risk. Conventionally, the pressure of the respiratory system is measured outside the patient. READ MORE

  4. 2. Spirodynamics. New methods for continuous monitoring of respiratory mechanics in ventilator-treated patients

    Author : Sigurbergur Kárason; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monitoring; Respiratory mechanics; Mechanical ventilation; Compliance; Alveolar pressure; Dynostatic algorithm; ALI; ARDS; Model; Human.;

    Abstract : Introduction: Ventilator treatment is often life-saving but has the inherent risk of causing damage to lung tissues. Overdistension and repetitive collapsing/opening of alveoli should be avoided. Monitoring of respiratory mechanics has a central role in accomplishing this. READ MORE

  5. 3. Cardiovascular and respiratory effects of apnea in humans

    Author : Johan Andersson; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lung volume; breath-hold diving; Apnea; breath-holding; face immersion; cold stimulation; diving response; diving reflex; circulation; bradycardia; vasoconstriction; arterial blood pressure; cardiac output; spleen; respiration; splenic contraction; alveol; Physiology; Fysiologi; Respiratory system; Andningsorganen; Animal physiology; Djurfysiologi;

    Abstract : This thesis deals with cardiovascular and respiratory effects of apneas in humans. During apnea (breath-holding), a number of interacting cardiovascular reflexes are initiated, and together these reflexes are called the “diving response”. READ MORE

  6. 4. 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

  7. 5. Experimental studies on effects of orthodontic forces in generation of immune responses : possible roles for immunoregulating molecules in the control of alveolar bone remodeling

    Author : Najat AL-Sayed AL-Hashimi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Orthodontic forces; inflammation; immune responses; cytokines; chemokines.;

    Abstract : The transformation of orthodontic forces to periodontal tissues involves several biological mechanisms, which ultimately result in bone remodelling. It has been suggested that the immune system plays a role in the regulation of bone remodelling through production of immune mediators by inflammatory cells that have migrated from dilated periodontal ligament capillaries after the application of orthodontic force.
