1. 1. Ventilation and Lung Volume During Sleep and in Obstructive Sleep Apnea

   Författare :Jonas Appelberg; Göran Hedenstierna; Christer Janson; Karl Franklin; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Sleep; Ventilation; Sleep apnea syndromes; Snoring; Lung volume; Respiration; Computed tomography; Ventilatory response; Ventilation-perfusion; Airway closure; Fysiologi; Physiology; Fysiologi; klinisk fysiologi; Clinical Physiology;

   Sammanfattning : Obstructive sleep apnea (OSA) appears to affect up to 5% of the population. The extent to what pulmonary function awake and during sleep relates to obstructive breathing and hypoxemia during sleep in these patients is unclear. LÄS MER

3. 2. Heart and lung function - in health and disease : methodological studies in clinical physiology

   Författare :Sofia Erelund; Nina Sundström; Urban Wiklund; Sandra Arvidsson; Bengt Johansson; Carl-Johan Carlhäll; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clinical physiology; reference materials; ECG; dynamic spirometry; HRV; rheumatoid arthritis; cardiovascular disease; ischemic heart disease; Clinical Physiology; klinisk fysiologi;

   Sammanfattning : The human heart and lungs constitute an intricate and dynamic system. Various clinical physiological examinations can be used to evaluate cardio-pulmonary function and identify abnormalities. Thus, it is important to understand how normal physiology presents, to be able to identify pathological findings. LÄS MER

4. 3. Dynamiskt lärande : En ämnesdidaktisk avhandling om fysiologiska fenomen och läkarstudentens lärande

   Författare :Anna Fyrenius; Staffan Wirell; Eva Nylander; Charlotte Silén; Kirsten Hofgaard Lycke; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lärande; Förståelse; Fysiologi; Clinical physiology; Klinisk fysiologi;

   Sammanfattning : It is well known that the outcome of teaching and learning in higher education is often unsatisfactory. Earlier studies have shown that medical students often have a surface approach to their studies and that misconceptions of fundamental physiological phenomena are common. LÄS MER

5. 4. Lung mechanics and airway inflammation in murine models of asthma

   Författare :Sofia Jonasson; Josephine Hjoberg; Hedenstierna Göran; Carl Persson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allergic asthma; airway inflammation; murine models; lung mechanics; forced oscillation technique; airway reactivity; deep inhalations; oxidative stress; nitric oxide; glucocorticoids.; Clinical physiology; Klinisk fysiologi; klinisk fysiologi; Clinical Physiology;

   Sammanfattning : Allergic asthma is an inflammatory disease of the airways and is characterized by eosinophilic inflammation and increased airway reactivity. In the studies presented in this thesis, lung mechanics and measurements of airway reactivity were assessed in anaesthetized tracheostomized mice by using an animal ventilator (flexiVent®). LÄS MER

7. 5. Optimizing and evaluation of a methacholine provocation test : with application in occupational research

   Författare :Britt-Marie Sundblad; Bengt-Eric Skoogh; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Airway responsiveness; methacholine provocation; nitric oxide; eucapnic hyperventilation; organic dust; Fysiologi; Physiology; Fysiologi; Physiology; fysiologi;

   Sammanfattning : We have developed a methacholine provocation method, which detects bronchial responsiveness in more than 80% of healthy subjects. The method enables us to detect differences in bronchial responsiveness within the normal range. With this method FEV1 and Gaw had similar sensitivity in detecting small differences in bronchial responsiveness. LÄS MER
