1. Ventilation and Lung Volume During Sleep and in Obstructive Sleep Apnea
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
2. Towards tailoring the product introduction process for low-volume manufacturing industries
Sammanfattning : As the closing phase of product development projects, the product introduction process significantly influences the time to market and product quality. The rapid launching of new products to market aids manufacturing companies in avoiding crucial consequences, such as a loss of market share and revenue and the early obsolescence of products in a globalized market.

3. Transpulmonary pressure during mechanical ventilation
Sammanfattning : Background: Mechanical ventilation can aggravate lung injury by repetitive opening and closing of lung units, overdistention and undue pressure on pulmonary structures. Guidelines exist for lung protective ventilation, but individualized ventilator settings, based on partitioning of respiratory mechanics in pulmonary and chest wall complex components, would be beneficial.

4. 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
5. Effects of gravity and posture on the human lung
Sammanfattning : The presence of the gravitational force at the surface of Earth affects all of the organ systems in landliving creatures. The function of the lung is particularly susceptible to changes in the direction and magnitude of gravity because of the elastic structure of this organ. LÄS MER
