Figure 2.

Patients admitted with trauma diagnoses during the study period; among these were patients on mechanical ventilation for more than 96 h (potentially fulfilling the criteria for IVAC of PVAP development), patients developing respiratory infection fulfilling criteria for VACs, and patients developing IVACs/PVAPs. For the last group, percentages are over total admissions (upper line) and over the number of individuals on MV for more than 96 h (lower line, between parenthesis). MV: mechanical ventilation; h: hours; IVAC: infection-related ventilator-associated complications; PVAP: possible ventilator-associated pneumonia; VAC: ventilator-associated conditions.
