Then, the variables defined for the software, including their age, sex, diagnosis, and chip tube number, are entered into the online minimap software. Software randomly divides patients into one of three groups. Sampling will continue this way until the required number of samples is completed. N/A Condition 1: ventilator associated pneumonia. Condition 2: oropharyngeal complications. Intervention 1: Intervention group: Oral care with swab and chlorhexidine solution 0.2% every 12 hours and equal care between groups (oral cavity moistening and lipsticking every 4 hours and oral suctioning if needed). Intervention 2: Intervention group: Oral care with toothbrush and chlorhexidine solution 0.2% every 12 hours and equal care between groups. Intervention 3: Intervention group: Oral care every 6 hours, twice with toothbrush and 0.2% chlorhexidine solution every 12 hours, twice with toothbrush and normal saline every 12 hours and equal care between groups.
