21. Cardiovascular and respiratory effects of apnea in humans
Sammanfattning : 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”. LÄS MER
22. Novel computational methods for image analysis and quantification using position sensitive radiation detectors
Sammanfattning : The major advantage of position sensitive radiation detector systems lies in their ability to non invasively map the regional distribution of the emitted radiation in real-time. Three of such detector systems were studied in this thesis, gamma-cameras, positron cameras and CMOS image sensors. LÄS MER
23. Radiological imaging of pulmonary emphysema : preoperative evaluation of candidates for lung volume reduction surgery
Sammanfattning : Lung volume reduction surgery (LVRS) for pulmonary emphysema, first described by Brantigan in 1957, was re-introduced by Cooper et al in 1995. From a surgical point of view, information on the extent and distribution of emphysema is mandatory and also partly determines the outcome. LÄS MER
24. Breathing and phonation : effects of lung volume and breathing behaviour on voice function
Sammanfattning : Respiration is believed to play a central role in voice function and is thus of relevance to the clinical care of the disordered voice. The overall aim of the present study was to experimentally investigate relationships between the respiratory and phonatory systems. LÄS MER
25. Lung function in micro- and in hypergravity
Sammanfattning : The lung is extremely susceptible to gravity, even during short-term changes of the gravity vector, because it is a mixture of air and elastic tissue components. Yet, there is limited knowledge of the effects of gravity on the respiratory system. LÄS MER
