Explain to me the procedure of a tracheostomy?

Hole in trachea: This is a surgical procedure where an opening is made in the front of the neck into the trachea to make it easier and safer to help a patient breathe using a ventilator (breathing machine). Often, this comes after the patient has used a tube going in the mouth and into the trachea. A tracheostomy tube avoids the vocal cords and the easy-to-damage area below them, and so is safer long-term.
