What is the primary focus during Preoxygenation in the intubation process?

Preoxygenation is a critical step in the intubation process that aims to increase the oxygen reserves in the patient's lungs, allowing for a safer period of apnea during the intubation. The primary focus is indeed to provide high-flow oxygen, often at 10-15 liters per minute, for an adequate duration of 3-5 minutes. This process helps to enhance the patient's oxygenation and provides a buffer against desaturation during laryngoscopy and intubation. By preoxygenating the patient, you can significantly improve their ability to maintain oxygen levels in the bloodstream, even in situations where ventilation is temporarily compromised.

This technique is especially important in emergencies or when time is of the essence, as it can mitigate the risks associated with hypoxia during the procedure. By ensuring the patient is adequately preoxygenated, clinicians can enhance the safety and effectiveness of the intubation process.
