Hypoxemia refers to low blood oxygen levels, while hypoxia denotes low tissue oxygen levels. Both conditions pose life-threatening risks when precautions are not adequately taken or when risks are not effectively managed. Intubation represents a critical phase that can lead to a decrease in arterial oxyhemoglobin levels. Two frequently employed techniques for preoxygenation and ventilation during intubation are bag-valve mask (BVM) ventilation and noninvasive mechanical ventilation (NIMV). The aim of this study was to evaluate the efficacy and safety of BMV and the NIMV.
