16. A Ventilation Strategy Based on Confluent Jets : An Experimental and Numerical Study
Abstract : This study presents air distribution systems that are based on confluent jets; this system can be of interest for the establishment of indoor environments, to fulfill the goals of indoor climate and energy-efficient usage. The main objective of this study is to provide deeper understanding of the flow field development of a supply device that is designed based on wall confluent jets and to investigate the ventilation performance by experimental and numerical methods.

17. Airway pressure release ventilation : A systematic experimental approach
Abstract : Airway pressure release ventilation (APRV) is a ventilatory mode which allows unrestrictedspontaneous breathing (SB) throughout the ventilatory cycle. If SB is insufficient, mechanicalventilatory support is achieved by brief periodic decreases of the airway pressure below the CPAPlevel. READ MORE

18. Open lung concept in high risk anaesthesia : Optimizing mechanical ventilation in morbidly obese patients and during one lung ventilation with capnothorax
Abstract : Formation of atelectasis, defined as reversible collapse of aerated lung, often occurs after induction of anaesthesia with mechanical ventilation. As a consequence, there is a risk for hypoxemia, altered hemodynamics and impaired respiratory system mechanics. READ MORE

19. Experimental and numerical investigations of a ventilation strategy – impinging jet ventilation for an office environment
Abstract : A well-functioning, energy-efficient ventilation system is of vital importance to offices, not only to provide the kind of comfortable, healthy indoor environment necessary for the well-being and productive work performance of occupants, but also to reduce energy use in buildings and the associated impact of CO2 emissions on the environment. To achieve these goals impinging jet ventilation has been developed as an innovative ventilation concept. READ MORE

20. Transpulmonary pressure during mechanical ventilation
Abstract : 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.
