Why is suctioning performed on mechanically ventilated patients?

Suctioning is performed on mechanically ventilated patients primarily to clear secretions from the airway. When patients are on mechanical ventilation, there is a risk of accumulating secretions in the airways due to various factors, such as the patient’s inability to effectively cough or because they may have increased mucus production due to underlying conditions. These secretions can obstruct airflow, impede ventilation, and complicate respiratory function.

By suctioning, healthcare providers can remove these obstructions, which helps to maintain a patent airway and ensures adequate ventilation and oxygenation. Clearing secretions also reduces the risk of infections and contributes to better overall pulmonary hygiene.

While the other options relate to various aspects of patient care, they do not accurately describe the main purpose of suctioning in this context. Adjusting ventilator settings, monitoring lung compliance, and increasing oxygen saturation do not directly involve the process of suctioning and are managed through different interventions and assessments.
