During those years, the United States evolved from a new nation fighting Great Britain for independence (1775â83), through the monumental American Civil War (1861â65) and, after collaborating in triumph during World War II (1941â45), to the world's sole remaining superpower from the late 20th century to present.
Tracheotomy (US /ËtreÉªkiËÉtÉmi/ tray-kee-AW-tÉ-mee) is a surgical procedure which consists of making an incision on the anterior aspect of the neck and opening a direct airway through an incision in the trachea (windpipe).
A tracheostomy is often needed when health problems require long-term use of a machine (ventilator) to help you breathe. In rare cases, an emergency tracheotomy is performed when your airway is suddenly blocked, such as after a traumatic injury to your face or neck. When a tracheostomy is no longer needed, it's allowed to heal shut or is surgically closed. For some people, a tracheostomy is permanent. Mayo Clinic's approach.
