With a complete airway obstruction, how quickly can a victim die if the airway is not opened?

In cases of complete airway obstruction, the time frame in which a victim can lose consciousness and potentially die is critical. The human brain is highly dependent on oxygen, and it only takes a few minutes without oxygen for irreversible brain damage to occur, typically around 4 to 6 minutes. If the airway is not opened promptly, the lack of oxygen can lead to death within approximately 5 minutes. This emphasizes the importance of immediate intervention in emergency situations where a person's airway is blocked. The options that indicate longer time frames do not align with the physiological needs of the human body, particularly concerning brain oxygen supply.
