Table 7: The correlation between selected inflammation indicators and VAP contraction time. The analysis of the correlation between epidemiological factors and VAP demonstrated that there is a statistically significant difference in contraction time of VAP in patients showing various epidemiological factors. In the case of VAP developing within 4 days, the most frequent epidemiological factors were _Staphylococcus aureus_ and _Streptococcus pneumoniae_, whereas in the case of VAP diagnosed from 5 th day, they were _Acinetobacter baumannii_, _Candida albicans_, and _Klebsiella pneumoniae_ (\(p=0.035\)) (Table 9). In the further analysis, the dependency between the combination of various risk factors (the occurrence of various risk factors in one patient simultaneously) and VAP contraction time was determined. The analysis included 9 risk factors:  
* albumin level in serum above 35 g/L;
* CRP value above 5 mg/L;
* leukocytes level above 10,000/uL;
* procalcitonin level above 0.5 ug/L;
* result \(\geq\) 3 in the NRS-2002 scale;
* age over 61 years;
* gender--male;
* multi-organ injury;
* total protein level in serum below 45 g/L. The statistical analysis included the group of patients in whom five or more risk factors were recognized due to the fact that, in this group, VAP occurred more often up to 4 days of intubation. The statistical analysis did not demonstrate any important influence \begin{table}
