Optimising the airflow performance of ventilators for natural ventilation in buildings.
… slots fabricated from pine wood to commercial ventilators and mesh-screens as are commonly found in natural ventilation applications. The results of this investigation indicate that the overall airflow properties of a ventilator are influenced by the combination of constituent components, the …

An investigation of the performance of a stationary siphoning type of roof ventilator
… across the open end of the stack. Stacks and ventilators of sizes 10, 12, 14, 16, 18, 20, and 24 inches were tested. All test results are based on zero difference in temperature between the wind tunnel air and the stack air and on no friction loss in the stack. The capacities listed are for …

An investigation into turbine ventilators as a potential environmental control measure to minimise the risk of transmission of tuberculosis - a laboratory and field study
TB is an airborne infectious disease which is spread by droplet nuclei, carrying Mycobacterium tuberculosis, in the air. The droplet nuclei small enough to enter human respiratory pathways are 1-5 μm in size and are able to travel long distances (Hodgson, et al., 2009) (WHO, 1999), and can be …

Natural ventilation in buildings: the development of a component
Wind activated rooftop ventilators have recently been rediscovered as appropriate energy conserving alternatives and/or supplements to power ventilation. Designers of passive solar heating/ cooling systems, for instance, often use ventilators in various ways as important components of their …

A European survey of Non- Invasive Ventilation (NIV)
… among Pulmonologists, and in AHRF. Dedicated NIV ventilators and ICU ventilators with NIV modules are preferably used in AHRF and in de-novo hypoxic respiratory failure, respectively, together with oro-nasal masks.

Oral Mucosal Microcirculation in the Context of Endotracheal Tube-Related Pressure Ulcer Development
… medical devices such as cardiac monitors, ventilators, non-invasive positive pressure ventilators, nasal gastric tubes (NG), orogastric tubes (OG), and urinary tract catheters. Nurses are challenged to prevent hospital acquired pressure ulcers (HAPUs) because many of these devices can cause …

Most Effective Nursing Interventions to Prevent Central Line-Associated Bloodstream Infections: A Critical Review of the Literature
… used in medical procedures, such as catheters or ventilators (Centers for Disease Control and Prevention, 2014). HAIs monitored by the CDC include central line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), ventilator associated pneumonia (VAP), …

… and a replacement and expansion of today’s smoke ventilators to roof lanterns. In order to achieve a flexible floor plan, two volumes are placed along the two long sides of the room. These volumes contain the offices and are divided with flexible, easy to move, inner walls. This allows the office …

The design and evaluation of the P₀.₁ method of assessing ventilatory drive
Hypercapnia and/or hypoxia normally cause hyperventilation, The sensitivity to hypercapnia and hypoxia and the resultant hyperventilation is reduced in a patient suffering from damped respiratory centre activity. The P 0.1 method is a modification of the rebreathing technique where a patient …
