Hospital Indoor Air Quality A Patient’s Death Threat

The Hospital acquired infection scenario

Studies on hospital acquired infections began more than 150 years ago with Ignaz Semmelweis and Florence Nightingale and contributed to the advance of microbiologic and prophylactic actions in hospital enviroments. Despite the increase of asepsis practices, hospital infections are still considered a public health concern.

Hospital indoor air, a micro-organism contamination mean

Many studies show that bio-aerosols (micro-organism conglomerates in suspension in the air) play an important role on the acquisition of infections being calculated as responsible for 10 to 20% of those cases.

The pathogens can be sprayed in many ways, via natural or forced ventilation system, water spray, skin scales released by patients and medical staff,

coughing and sneezing . Studies also show that surgical staff members can liberate between 1,500 to 50,000 bacteria per minute and those pathogens may stay in suspension in the air for long periods of time. Studies reveal that 80 to 90% of all surgical wound infections are related to bad air quality and that cleaner air translates into in lower infection risk.
