I need a lesson in how a tracheotomy works. Just because there is an opening in your throat that goes to your lungs, how does that keep you oxegenated? Do you still need some artifical means of pushing air into the lungs? tia
In Jahi's case, yes. As she has no inspiratory or diagphramatic muscle function due to her brainstem damage, she cannot ventilate enough air to oxygenate her lungs. She would need mechanical ventilation through the tracheostomy with tubing and a machine.
Other kinds of patient who do have chest wall and diagphramatic muscle funtion can ventilate enough air to adequately oxygenate themselves. The classic is the patient who has a permanent tracheostomy because they have had a complete removal of the larynx due to cancer. They can (and do) even continue to smoke through them.
