  1. 1. Resistance breathing with PEP and CPAP : effects on respiratory parameters

    Författare :Maria Sehlin; Ola Winsö; Karin Wadell; Fredrik Öhberg; Monika Fagevik Olsèn; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chest physiotherapy; breathing exercises; PEP; CPAP; airway pressure; airflow; threshold resistor; flow resistor; inspiratory capacity; Borg CR10;

    Sammanfattning : Background: Positive expiratory pressure (PEP) and continuous positive airway pressure (CPAP) are two forms of resistance breathing used in spontaneously breathing patients. With a threshold resistor or a flow resistor, both PEP and CPAP provide a positive (elevated) pressure level during the expiratory phase. LÄS MER

  3. 2. Functional residual capacity – development of new monitoring techniques for critically ill patients

    Författare :Cecilia Olegård; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FRC functional residual capacity EELV end-expiratory lung volume volume dependent compliance VDC acute respiratory failure recruitment manouvre PEEP;

    Sammanfattning : Functional residual capacity (FRC) and end-expiratory lung volume (EELV) are important parameters for respiratory monitoring in critically ill adult and paediatric patients. Until now we have lacked clinically useful methods to measure these lung volumes. LÄS MER

  4. 3. Lung function after cardiac surgery : With special reference to atelectasis and ventilation-perfusion relationships

    Författare :Arne Tenling; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Cardiac surgery; thoracic epidural analgesia; vital capacity manoeuvre; computed tomography; ventilation-perfusion relationships; gas exchange; atelectasis; respiratory inductive plethysmography; Kirurgi; Surgery; Kirurgi; anestesiologi; Anaesthesiology;

    Sammanfattning : Patients undergoing cardiac surgery were investigated before and after the operation.Ventilation-perfusion (VA/Q) relationships were examined by the multiple inert gas elimination method, and atelectasis and aeration of the lungs were examined by computedtomography (CT).

  5. 4. 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

  7. 5. Ventilatory aspects of sleep and activity in patients with neuromuscular disorders

    Författare :Brita Klefbeck Stridsman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :assisted ventilation; cervical cord injury; inspiratory muscle training; neuromuscular diseases; sleep; oximetry; trunk stability;

    Sammanfattning : Patients with cervical cord injuries (M) and slowly progressive neuromuscular diseases, such as prior polio and muscular dystrophy, often have decreased ventilatory capacity. This could affect both their daytime level of activity and sleep quality. LÄS MER
