1. On the Formation and Physical Behaviour of Exhaled Particles
Abstract : Aerosol particles are generated in human airways and leave the body with exhaled air. The particles originate from the respiratory tract and contain non-volatile compoundsthat potentially may be used as biomarkers for various medical conditions. To utilise any information provided by the particles, they must be characterised. READ MORE

2. Lung volumes and lung mechanics in anesthetized children
Abstract : The thesis was intended to fill gaps in the knowledge regarding the normal development of lung volumes and lung mechanics in children, from young infancy to the mid-teens. In particular, data were previously lacking regarding pre-school children. The studies were done during anesthesia and muscle relaxation. READ MORE

3. Analysis of Endogenous Particles in Exhaled Air
Abstract : Exhaled air contains non-volatile particulate material from the respiratory tract. The precise location in which exhaled particles are formed is unknown, and details on their chemical content are scarce. The aim of this work was to chemically characterize and to study the mechanisms of formation of endogenous particles in exhaled air. READ MORE

4. Ventilation and Lung Volume During Sleep and in Obstructive Sleep Apnea
Abstract : 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. READ MORE

5. FRC in acute lung injury. Experimental and clinical studies
Abstract : 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. READ MORE
