In cases where a person is not breathing, which method is most commonly used for artificial ventilation?

The most commonly used method for artificial ventilation in cases where a person is not breathing is mouth-to-mouth. This technique involves sealing the lips around the victim's mouth and delivering breaths directly into their airway. It is a straightforward method that can be quickly performed in emergencies to provide breaths until more advanced medical help is available or additional equipment can be utilized.

While other methods may also be used in certain contexts, mouth-to-mouth ventilation is often the first recourse in situations where immediate assistance is needed. It requires little equipment and is easily accessible to bystanders who may not have specialized tools on hand.

In contrast, while bag-valve mask ventilation is an effective method, it generally requires training and specific equipment to use properly, making it less accessible for the average person in emergency situations. Chest compressions are critical for maintaining blood circulation in cases of cardiac arrest, but they do not provide ventilation, which is essential in addressing the lack of breathing. Mouth-to-nose can be used if mouth-to-mouth is not an option, but it is not as widely practiced or recognized as the standard method for artificial ventilation.
