This study analyzed four nursing interventions: oral care, repositioning, endotracheal suction, and hygienic measures.
Endotracheal suction is only performed if necessary, on occasions with decreasing saturation, increasing peak pressure in the ventilator, coughing, or sounds from the endotracheal tube.
The total number of nursing interventions analyzed was 1,717: oral care (n = 171), repositioning (n = 571), endotracheal suction (n = 393), hygienic measures (n = 93), and simultaneous interventions (n = 489; Table 2).
