Hospital acuired Pneumonia

Pneumonia is the second most common type of nosocomial infection. Microorganisms are easily introduced into and colonize the throat.  Microorganisms can come from contaminated equipments as mechanical ventilators or hands of health care workers or procedures conducted as respiratory intubation and suction of materials from mouth or throat. Once throat is colonized, it is easy for a patient to aspirate the microorganisms in the lung where infection develops that lead to pneumonia.
