Term
Community acquired pneumonia (CAP
Definition
Acute infection of the pulmonary parenchym
presence of an acute infiltrate consistent with pneumonia on chest radiography or ausculatory findings
must NOT have been hospitalized 2 days or more within the last 90 days, be a resident in a long-term care facility, have received IV antibiotic therapy, chemotherapy, or wound care in the past 30 days, or attendance at a hospital or hemodialysis clinic.
Term
Health care-associated pneumonia (HCAP
Definition
pneumonia developing in a patient who was hospitalized in an
acute care hospital for 2 or more days within 90 days of the infection
who resided in a nursing home or long-term care facility
who received recent antibiotic therapy, chemotherapy, or wound care within the past 30 days of the current infection;
who attended a hospital or hemodialysis clinic
Term
Hospital-acquired pneumonia (HAP
Definition
pneumonia that occurs 48 hours or more after admission and is not incubating at the time of admission
Term
Ventilator-associated pneumonia (VAP):
Definition
pneumonia that arises more than 48 to 72 hours after endotracheal intubation
Term
Pathogenesis
Definition
Invasion of organisms that colonize the lower respiratory tract by:

Inhalation of pathogens into lower respiratory tract
Aspiration of pathogenic organisms from the oropharynx
VAP most likely caused by microbes that have been dragged into the airways during the intubation procedure.
