1. Describe how to perform an endotracheal intubation. What dangers are associated with this procedure?

An endotracheal intubation is characterized by the insertion of a tube into the trachea to maximize air-flow to and from the lungs. Thus it is most commonly performed on unconscious/critical-care patients who are unable to maintain proper respiration of their own or on patients under sedation (e.g. patients undergoing surgery). Medical practitioners start off the procedure by positioning the head of the patient at an angle that allows for maximal exposure of the airway, next a laryngoscope is employed to move the tongue out the way, once the trachea is adequately exposed a flexible plastic tube is inserted into the trachea through the mouth or nose.

The most common risk associated with this procedure is the possibility of erroneously placing the tubing in the esophagus (or the food pipe) of the patient instead of in their trachea (or the wind pipe). Wrongly placed or too deeply placed tubing will not be effective in ensuing proper respiration and may lead to several health complications, including brain damage and heart attack. If the conducting physician is not careful then the throat tissues and vocal cords of the patient can also incur severe damage....
