Intubation is a medical procedure in which a tube is inserted into a person's airway to help them breathe or protect their airway. It is commonly used during surgeries, in emergency situations, or in critically ill patients who are unable to breathe on their own. Intubation may be performed orally or nasally, and is typically carried out by a trained healthcare professional, such as a doctor or respiratory therapist. The tube used in intubation is connected to a ventilator or other breathing device to provide oxygen to the patient's lungs. Intubation is a crucial procedure in many medical settings and requires careful monitoring and skill to ensure the patient's safety and comfort.
