Hybrid Ventilation Flows
Hybrid ventilation is likely to become an increasingly important element of low-energy building design, as it is often perceived to embody both the energy efficiency of natural ventilation, and the control and reliability of mechanical ventilation. However, at the outset of this work there was …

Determinants of ventilation during exercise
… support a role of potassium in the regulation of ventilation. Further, numerous authors have suggested that submaximal threshold indices can accurately predict performance. The following conclusions were drawn from the results of this thesis:(1) changes in ventilation during exercise are regulated …

Natural ventilation generates building form
Natural ventilation is an efficient design strategy for thermal comfort in hot and humid climates. The building forms can generate different pressures and temperatures to induce natural ventilation. This thesis develops a methodology that uses a computational fluid dynamics (CFD) program. The …

Floor-supply displacement ventilation system
… Therefore, it is necessary to provide a good ventilation system that can provide good indoor environment. To improve indoor air quality, displacement ventilation systems can work well. The system provides fresh air directly to the occupied zone. However, the existing floor-supply displacement …

Scale model studies of displacement ventilation
Displacement ventilation is an air conditioning method that provides conditioned air to indoor environments with the goal to improve air quality while reducing energy consumption. This study investigates the performance of displacement ventilation systems in open plan office environments, focusing …

Intelligent Decision Support Systems in Ventilation Management
… medical personnel, in an ongoing process termed ventilation management, utilize patient physiology and pathology data to define ventilator apparatus settings. Aims: The aim of the research is to develop and evaluate in comparison hybrid ventilation advisor systems, that could support ventilation …

Modeling buoyancy-driven airflow in ventilation shafts
… buildings. Such systems rely on atria or ventilation shafts to provide a pathway for air to rise through the building. Although numerous modeling techniques are used to simulate naturally ventilated buildings, airflow network tools (AFNs) are most commonly used for annual simulations. …

The pediatric mechanical ventilation in Canada (PeMViC) study: A Delphi survey of pediatric mechanical ventilation practices by Canadian respiratory therapists
The gap in knowledge for pediatric mechanical ventilation (MV) management makes practice standardization difficult. The European Society for Pediatric and Neonatal Intensive Care (ESPNIC) was the first to establish consensus recommendations on pediatric MV management. In Canada, respiratory …
