Answer Key

1. Intubation is a medical process where an endotracheal tube is inserted through a person’s mouth and into their windpipe (trachea). This procedure is done to assist patients who are unable to breathe on their own due to anesthesia, sedation, or severe illness. A patient who has undergone this procedure is referred to as “intubated.”
2. The main purpose of intubation is to ensure a clear airway, allowing air to pass smoothly to and from the lungs. It helps patients who cannot breathe on their own, ensuring that clean, oxygenated blood circulates throughout the body to keep vital organs functioning.
3. Intubation is required when a patient cannot protect their airway or breathe unassisted. This includes patients under general anesthesia for surgery (as anesthetic drugs can paralyze breathing muscles), patients with severe respiratory failure due to conditions like pneumonia or COPD, and patients who are unconscious.
4. Medical specialists who perform intubation include anesthesiologists, intensive care unit (ICU) doctors, and emergency room doctors. These physicians are trained in managing acute, life-threatening conditions and providing care for critically ill or injured patients.
5. The process of removing the breathing tube is called extubation. This procedure is performed when the patient’s condition has improved to the point where they can breathe effectively on their own and their blood is sufficiently oxygenated without mechanical support.
6. The patient is positioned on their back, and their mouth is gently opened. A device with a light is used to guide the endotracheal tube past the tongue, through the throat, and into the windpipe. Once in place, a small balloon on the tube is inflated to secure it, and placement is confirmed with a stethoscope and a chest X-ray.
7. Nasal intubation is a less common procedure where the breathing tube (a nasotracheal tube) is passed through the nose instead of the mouth. It is typically used when there is a need for surgery in the mouth or throat, or if there is an injury to that area, as it keeps the mouth clear for the surgical team.
8. The intubation procedure for children is fundamentally the same as for adults, but it requires smaller equipment. The process must be performed with greater sensitivity because a child’s airway is smaller. Nasal intubation is more commonly preferred for infants and newborns.
9. Potential risks include trauma to the teeth, mouth, tongue, larynx, or trachea. Other complications can include aspiration of saliva or other fluids, pneumonia, sore throat, and hoarseness.
10. In COVID-19 treatment, intubation is used as a supportive measure for patients with severe respiratory distress. It does not cure the virus but helps the patient breathe and maintains oxygenation, allowing the body’s resources to be focused on fighting the infection.
