T88.4: Failed or difficult intubation

There can be a variety of reasons why someone is unable to breathe without assistance. For example, some operations involve giving medication that prevents the patient from being able to breathe without assistance. Then the patient has to be ventilated. To do this, a tube is inserted into the trachea. The trachea or windpipe begins below the larynx. It consists of many cartilage rings that strengthen the trachea. The trachea splits into 2 large airways in the middle of the chest. The airways then go into the lungs and branch out further.

It can be difficult to put the tube into the trachea. This can cause injuries to your throat or mouth, for example. It may also prove impossible to insert the tube into your airways.
