Brief Summary:
The investigators are suggesting that closed suction systems may reduce the risk of the ventilator - associated pneumoniae (VAP) and the contamination of the closest unanimated surfaces. In 2011 David et al. have shown that closed suction systems might reduce the incidence of the late VAP. Research team is thinking that preventive bundle with closed suction systems can prevent to onset of the VAP. All enrolled patients is randomizing into two groups: control group - conventional suctioning and research group - suctioning with closed suction system.

Primary Outcome Measures :
  1. incidence of the ventilator - associated pneumoniae (VAP) [ Time Frame: Change from Baseline CPIS at 96 hours ]
    Assessment of CPIS, if CPIS equal or more 6 points VAP will be observed

  2. Contamination of closet inanimate surfaces [ Time Frame: Change from Baseline Microbiology researching at 96 hours ]
    Microbiology researching samples from circuit of a respirator and a bed

Secondary Outcome Measures :
  1. Organ dysfunction [ Time Frame: Change from Baseline SOFA at 96 hours ]
    Patient examination with Sequential Organ Function Assessment (SOFA)

  2. Mortality [ Time Frame: 28 days ]
    Mortality for 28 days of a hospitalization

  3. C - reactive protein [ Time Frame: Change from Baseline CRP researching at 96 hours ]
    Investigation of a Biomarker of the VAP

  4. Procalcitonin [ Time Frame: Change from Baseline CRP researching at 96 hours ]
    Investigation of a Biomarker of the VAP

  5. sTREM 1 [ Time Frame: Change from Baseline CRP researching at 96 hours ]
    Investigation of a Biomarker of the VAP
