Air entering the stomach
During mechanical ventilation, air is usually directed into the victim's lungs. But in some cases, air may enter the stomach instead of the lungs. Do not overfill the victim's lungs with air. Stop inflating as soon as his chest rises. In addition, if the victim's head is not sufficiently thrown back, the airway will be partially open and the rise of the chest may be insignificant. This may cause the rescuer to inhale more forcefully and force air into the stomach. Finally, if the insufflations are done too quickly, the increased pressure in the airways also causes air to enter the stomach. When performing long, slow insufflations, the pressure in the airways decreases.
Getting air into the stomach is dangerous because it can cause vomiting. If an unconscious victim vomits, the vomit may enter the lungs. This is called aspiration. Aspiration makes artificial ventilation difficult and can lead to fatal consequences.
Vomit
During artificial ventilation of the lungs, the victim may begin to vomit even without air entering the stomach. In this case, turn the victim to the side, keeping the head and spine on the same axis. This helps prevent vomit from entering the le-
Gen. Quickly clean the victim's mouth and, placing him back on his back, continue artificial ventilation.
