OVERVIEWHealthcare Associated Infections (HAIs), or Nosocomial infections, are one of the leading causes of death in the United States of America more than Breast Cancer, AIDS, and Auto Accidents combined.According to the American CDC (Centers for Disease Control and Prevention),one of every 25 patients contracts an infection in the hospital causing more than 75,000 deaths each year in the US.205 Americans die from Hospital-Acquired Infections each day.HAI cost almost $10 billion annually in the US.Airborne transmission is one of the environmental routes of Nosocomial infections in hospitals such as Infl uenza, SARS, Measles, Tuberculosis.Hospital occupants (patients, Hospital staff, visitors)

and their activities are responsible for most of the contaminants in the conditioned space and some microorganisms are transmitted directly from person to person in the form of droplets in the air. When droplets are produced during a cough or sneeze, a cloud of infectious particles is released into the air, resulting in potential exposure of susceptible persons within three feet of the source person.The coarsest particles (larger than 2.5 micrometers) fall fast enough, their residence time in the air is of the order of 1 day, while the fi nest can stay up to 1 week in suspension and travel thousands of kilometers. Once deposited, the particles can then be re suspended by the wind or by indoor air fl ow.

OBJECTIVEMonitor 24/7 Indoor air quality (particles, VOCs, CO2, RH, Temperature) from any computer or smartphone or from central building control system to detect risk of contagious airborne diseases and environment pollution risk (viruses, bacteria, spores, VOCs).

For particles :Principle of detection The P4000 uses laser diffraction technology (Light Scattering)

maeb resal a nehw :gniwollof eht si elpicnirp ehTpasses through pure air, the beam is invisible. When the beam is visible, this is because the beam is diffracted onto particles along its path. If you look at beam from the side, the more the beam is visible, the more the particle density. This particle probe uses a sensor with a near-infrared source (laser diode). The sensor is an avalanche photodiode with amplifi er. Infrared is used to avoid

TECHNOLOGY

OPERATIONThe device must be placed in the area of occupancy of the premise served by outlet vents AMD mounted on a wall at eyes level (breathing human level, between 1.5 and 1.8m).
