Made by Down Bros of London for the Air Ministry. A tracheotomy is a surgical procedure where an incision is made into the trachea (windpipe) and a tube is inserted to enable the patient to breathe. It is normally carried out when the airway above the trachea is damaged or blocked, making unasisted breathing imposible.
