In which situation should artificial respiration techniques be employed?

Artificial respiration techniques should be employed in cases of drowning or respiratory failure because these situations indicate that the individual is unable to breathe effectively or at all. Drowning leads to water inhalation, which can block the airways and prevent oxygen from entering the lungs, necessitating immediate intervention. When a person is in respiratory failure, it means their body is not getting enough oxygen, which can lead to critical consequences if not addressed promptly.

In these scenarios, artificial respiration can help restore normal breathing by providing oxygen when the individual is unable to do so independently. This is vital in preventing brain damage or death due to hypoxia, the condition that occurs when there is insufficient oxygen supply to the tissues. The goal of using artificial respiration is to maintain oxygen levels in the body until professional medical help can arrive or until the individual can breathe on their own again.
