What is one of the primary goals of mechanical ventilation?

One of the primary goals of mechanical ventilation is to support or improve gas exchange in patients. Ventilation is a critical component of respiratory management, especially in individuals who cannot maintain adequate oxygenation or carbon dioxide removal on their own due to illness or injury. By providing assistance through mechanical means, the ventilator can enhance the delivery of oxygen to the lungs and facilitate the expulsion of carbon dioxide. This is essential for restoring and maintaining proper physiological function, preventing complications related to hypoxia (low oxygen levels) and hypercapnia (high carbon dioxide levels).

In contrast, while patient comfort, sedation, and spontaneous breathing are important considerations in the care of a patient on mechanical ventilation, they do not capture the primary objective of ventilatory support, which is fundamentally about ensuring that adequate gas exchange occurs. Restoring effective pulmonary function is paramount in both acute and chronic respiratory failure scenarios, making gas exchange the central focus of mechanical ventilation.
