What is the primary goal of positive pressure ventilation?

The primary goal of positive pressure ventilation is to facilitate oxygenation. This method involves delivering air into the lungs, which helps increase the amount of oxygen available to the blood and assists in removing carbon dioxide. By creating a positive pressure within the airways during inspiration, this technique can effectively overcome any obstructive forces and ensure that adequate volumes of air reach the alveoli where gas exchange occurs.

While increasing lung capacity, enhancing lung compliance, and reducing airway resistance may have their benefits in certain contexts, they are not the primary objectives of positive pressure ventilation. The fundamental aim remains to ensure that oxygen is effectively delivered to the lungs and subsequently into the bloodstream, which is crucial for maintaining cellular metabolism and overall physiological function.
