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 a surgical procedure to cut an opening into the trachea (windpipe) so that a tube can be inserted into the opening to assist breathing. A tracheostomy may be temporary or permanent, depending on the reason for its use. For example, if the tracheostomy tube is inserted to bypass a trachea that is blocked by blood or swelling, it will be removed once regular breathing is once again possible.
