What is the primary goal of using mechanical ventilation?

The primary goal of using mechanical ventilation is to enhance gas exchange. This is achieved by providing a controlled means of delivering oxygen to the lungs and removing carbon dioxide from the body, which is critical for maintaining adequate oxygenation and preventing respiratory failure.

In patients who cannot breathe effectively on their own due to conditions such as respiratory distress, mechanical ventilation helps support the respiratory system, ensuring that the necessary exchange of gases occurs efficiently. While drug delivery, circulation assistance, and sedation may be considerations in the overall management of a patient, mechanical ventilation's main function is directly related to improving gas exchange, which is essential for sustaining life and optimal organ function.
