Health care spaces are cited as good opportunities for natural ventilation
(Levin 2008), and the practice of naturally ventilating health care spaces has been adopted in contemporary installations outside of the United States.
Humidity results in Table 2 show that both groups had a reduction in moisture levels, but that the decrease was much greater and statistically significant with mechanical ventilation
Table-II: Association between duration of ventilation
and underlying etiology with outcome.
It will allow mine survey and design data to be used in ventilation
and cooling analysis, without replication of data, and ensures accurate, current representations of the mine surface can be applied to ventilation
Volution Group is a supplier of ventilation
products to the residential and commercial construction market in the UK and northern Europe.
An invitation to participate in the online survey on ventilation
management was sent to 776 college members.
The original ventilation
system for the tunnel is a point-extract system comprising axial fans housed in a single fan room located above the tunnel at its approximate mid-point.
Cessation of pulmonary circulation and ventilation
during extracorporeal circulation may lead to structural alterations of the lungs2.
My earliest experience with 'closed-loop' ventilation
started some 25 years ago (in 1988), when I started studying the clinical use of mandatory minute volume ventilation
using an Ohmeda CPU 1 electronic ventilator with my colleagues Peter Potgieter and Stan Davis in the respiratory intensive care unit at Groote Schuur Hospital, Cape Town.
The surgeons were not entirely blinded to the ventilation
mode since the portable ventilator has a distinctive sound.
There are economic and energy-efficiency rationales for reducing total residential mechanical ventilation
and for designing and operating ventilation
systems with variable amounts of ventilation
airflow (Concannon 2002; Russell et al.
is commonly due to building design.
