11. Optimizing mechanical ventilation in extremely preterm infants
Sammanfattning : Extremely low gestational age newborns (ELGANs) i.e. infants born before 28 weeks of gestational age (GA), require respiratory support during their hospital stay, and a majority needs mechanical ventilation (MV) at some time point. LÄS MER
12. Ventilation Performance in Operating Rooms : A Numerical Assessment
Sammanfattning : Surgical site infections (SSIs) remain one of the most challenging postoperative complicationsof healthcare and threaten the lives of millions of patients each year. Current evidence hasshown a positive relationship between the airborne concentration of bacteria-carryingparticles (BCPs) in the operating room (OR) and the rate of infections. LÄS MER
13. Advances in Ventilation Heat Recovery : An assessment of peak loads shaving using renewables
Sammanfattning : The building sector accounts for approximately 40% of total global energy usage.In residential buildings located in cold climate countries, 30-60% of this energy isused for space heating, 20–30% is lost by discarded residential wastewater, and therest is devoted to ventilation heat loss.

14. Modelling of Turbulent Flow and Heat Transfer for Building Ventilation
Sammanfattning : This thesis contributes to studies on the assessment of building ventilation performance and the development of turbulence models accounting for Low-Reynolds-number (LRN) effects and buoyant convection with heat transfer. Assessments of building ventilation performance are discussed with respect to indoor air distribution and passive contaminant dispersion. LÄS MER
15. Benefits of Spontaneous Breathing : Compared with Mechanical Ventilation
Sammanfattning : When spontaneous breathing (SB) is allowed during mechanical ventilation (MV), atelectatic lung areas are recruited and oxygenation improves thereby. Whether unsupported SB at its natural pattern (without PEEP and at low pressure/small tidal volume) equally recruits and improves oxygenation, and if so by which mechanism, has not been studied.
