Oral care is an important nursing activity that helps protect patients' oral health and allows for quicker recovery. For ventilated patients in the ICU, improving oral hygiene through regular mouth care can reduce infections like ventilator-associated pneumonia and lower mortality. Several solutions are used for mouth care in the ICU, including chlorhexidine and other antiseptics. Proper mouth care procedures for unconscious patients involve cleaning the mouth, teeth, and gums with a toothbrush and suctioning secretions while keeping the patient in a safe position.
