What is the primary goal of preoxygenation prior to intubation?

The primary goal of preoxygenation prior to intubation is to increase oxygen saturation levels. This process is essential because it ensures that the patient has an adequate supply of oxygen in their system before the airway is secured. When a patient is intubated, there can be a period during which their ventilation is compromised, either due to difficulty in placing the tube or because effective ventilation cannot be achieved immediately.

By increasing oxygen saturation levels before intubation, you are effectively creating a reserve of oxygen that the body can use during this critical period. This helps to minimize the risk of hypoxia and ensures that vital organs receive oxygen even as the airway is being managed.

While reducing the workload of breathing, preparing the lungs for ventilation, and assisting with drug administration are important considerations in airway management, they are not the primary objective of preoxygenation. The focus here is specifically on bolstering the patient's oxygen reserves to maintain adequate perfusion and organ function during the intubation process.
