|
Community Acquired Pneumonia (CAP)
|
Usually follows an initial viral infection
Occurs in the community Or Within 48 hours of admission to the hospital Most common bacteria: Streptococcus pneumoniae (organism) Mycoplasma pneumoniae (organism) Haemophilus influenza (organism) Viruses |
|
Hospital Acquired Pneumonia(HAP)
|
Onset: > 48 hours after admission
No evidence of infection at time of admission 3 conditions exist: Host defenses are impaired Portions of a pathogen capable of causing infection overtake host’s defenses Highly virulent organism is present |
|
VAP
|
ventilator associated pneumonia
Patients with acute respiratory failure requiring mechanical ventilation > 48 hours |
|
Common Organisms for HAP
|
Klebsiella
Serratia Pseudomonas aeruginosa Methicillin-resistant staph aureus (MRSA) HIGH MORTALITY RATES |
