Obtain blood cultures as early as possible, although they are infrequently positive, except in cases of hematogenous nosocomial pneumonia. The recovery of MSSA/MRSA in blood cultures in patients with nosocomial pneumonia/VAP without the clinical findings of MSSA/MRSA pneumonia (eg, rapid cavitation, high fevers, cyanosis) is likely due to skin contamination of blood cultures.
