Step-by-step explanation:
Intubation is a procedure used to create an airway by placing a tube through the nose or mouth into the windpipe. It is commonly performed by ambulance crews in cases where the respiratory system is blocked or injured. During intubation, a long plastic tube is inserted into the respiratory system, allowing air to bypass the blocked area and reach the lungs. This tube is connected to a squeezable bag that supplies artificial air. The procedure helps ensure that the patient can breathe properly and receive oxygen. After the patient recovers, the tube is removed.
