  2. 1. Ventilation distribution in the lung periphery measured by inert gas washout : influence of increased gravity, anti-G suit pressure, body posture, and breathing pattern

    Author : Mikael Grönkvist; Göran Hedenstierna; Linköpings universitet; []
    Keywords : acceleration; anti-G suit; body posture; cdi; dcdi; human centrifuge; He; hypergravuty; lung; multiple-breath washout; single-breath washout; SF 6; standing; supune; trapped gas; ventilation distribution; MEDICINE; MEDICIN;

    Abstract : The lung is highly sensitive to forces of gravity and acceleration, and to surrounding pressures. This thesis aimed to assess the effects on ventilation distribution in peripheral lung units when changing the direction or magnitude of the gravitational vector and when compressing the lower body half with an anti-G suit (AGS).

  4. 2. Peripheral airway function in asthma and cystic fibrosis. Measurements using inert gas washout methods

    Author : Henrik Ljungberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acinar; adults; airway hyperresponsiveness; asthma; children; conductive; functional residual capacity; gas trapping; inert gas washout; infants; peripheral airways; plethysmography; respiratory function tests; ventilation inhomogeneity;

    Abstract : It is increasingly recognised that asthma and cystic fibrosis (CF) frequently involves the peripheral airways. Characteristic features of abnormal peripheral airway function are uneven ventilation distribution and increased gas trapping. READ MORE

  5. 3. Exahaled NO and small airway function in asthma and cystic fibrosis

    Author : Christina Keen; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; exhaled NO; children; cystic fibrosis; flow independent exhaled nitric oxide; multiple breath inert gas washout; polyunsaturated fatty acids;

    Abstract : Background: Asthma and cystic fibrosis (CF) are chronic inflammatory airway disorders known to involve the peripheral airways. Non-invasive tests sensitive to peripheral airway function and inflammation are therefore of high priority. READ MORE

  6. 4. Respiratory and esophageal morbidity in adults with repaired esophageal atresia

    Author : Vladimir Gatzinsky; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Esophageal atresia; Long-term outcome; Pulmonary function; Esophageal morbidity; Gastro-esophageal reflux; Dysphagia;

    Abstract : Background: Esophageal atresia (EA) often leads to persistent esophageal and respiratory symptoms, as well as impaired esophageal and lung function in adulthood. The reasons for this, and the connections between symptoms and documented abnormalities, are not fully understood. READ MORE
