What Is Mitral Regurgitation? Mitral regurgitation (MR) occurs when the heart's mitral valve does not close completely, allowing blood to regurgitate (or leak) through the valve when it should be closed. Here is a brief review of the heart's chambers and valves.
A tracheostomy usually takes 20 to 45 minutes to perform. The surgeon or other health care professional will make a cut through the lower front part of your neck and then cut into your windpipe. Cuffed trach tubes may be used. These tubes use air to widen or narrow the tube to fit the hole.
Tracheotomies were used in the early 1800's for airway inflammation in children due to Diphtheria. The first documented successful tracheotomy performed on a child was reported in 1808. The Tracheotomy Tube, short story of a child with a trach in 1892. Photo's of Antique Tracheostomy Tubes.
