What is a common indication for intubation in ICU patients?

Severe respiratory failure is a common indication for intubation in ICU patients because it poses an immediate risk to the patient's airway and ability to breathe effectively. In cases of respiratory failure, the patient's oxygenation and ventilation are compromised, leading to life-threatening hypoxemia or hypercapnia. Intubation allows for the secure placement of an endotracheal tube, ensuring that the airway is protected and facilitating mechanical ventilation if necessary. This intervention helps restore adequate gas exchange and supports the patient's respiratory needs until the underlying cause can be addressed.

In contrast, uncontrolled hypertension is typically managed with medications and does not usually require intubation, as it does not affect airway patency. Similarly, acute liver failure may require intensive monitoring and management but is not an indication for intubation unless there are accompanying respiratory issues. Chronic pain management generally does not relate to the need for intubation and is managed with appropriate pharmacologic therapies instead.
