Localized Ventilation Method for Providing Clean Air to Hospitalized Patients

Why Is Clean Air Clean?

Air exhibiting very low concentrations of light-scattering aerosol particles is occasionally observed even in industrialized regions. Evidence is presented that this very clean air results from highly efficient removal of aerosol particles coupled to the removal of water in precipitation.

Ten principles for clean air.

T he European ‘‘Year of the Air’’ 2013 will be upon us soon: over the next several months, the European Union (EU) will revise its main air pollution control policies. Lack of clean air is one of the most important environmental threats to public health in Europe today. The European Respiratory Society Environment and Health Committee (www.ersnet.org) has developed 10 concise principles for cle...

Providing Design Strategies for Ventilation System in Treatment Environments (Proposed Sample: Hybrid Ventilation System in Hospitals)

One of basic principles in designing treatment environments is to design air conditioning/ventilation system proportionate to environment. Essentially, appropriate air conditioner in treatment spaces must bear the following capabilities: providing healthy and clean air, reducing the concentration of pollutants produced in the atmosphere, emission of pollutants and impeding their spread in exter...

Providing clean water, keeping water clean: an integrated approach.

Millions of people, most of whom are children in developing countries, die of basic hygiene-related diseases every year. Interventions in hygiene, sanitation and water supply have been shown to control disease burden. Universal access to improved water sources and basic sanitation remains elusive but is an important long-term goal. Studies have shown that improving the microbiological quality o...
