| swan | 1. <zoology> Any one of numerous species of large aquatic birds belonging to Cygnus, Olor, and allied genera of the subfamily Cygninae. They have a large and strong beak and a long neck, and are noted for their graceful movements when swimming. most of the northern species are white. In literature the swan was fabled to sing a melodious song, especially at the time of its death. The European white, or mute, swan (Cygnus gibbus), which is most commonly domesticated, bends its neck in an S-shaped curve. The whistling, or trumpeting, swans of the genus Olor do not bend the neck in an S-shaped curve, and are noted for their loud and sonorous cry, due to complex convolutions of the windpipe. To this genus belong the European whooper, or whistling swan (Olor cygnus), the American whistling swan (O. Columbianus), and the trumpeter swan (O. Buccinator). The Australian black swan (Chenopis atrata) is dull black with white on the wings, and has the bill carmine, crossed with a white band. It is a very graceful species and is often domesticated. The South American black-necked swan (Sthenelides melancorypha) is a very beautiful and graceful species, entirely white, except the head and neck, which are dark velvety seal-brown. Its bill has a double bright rose-coloured knob. 2. An appellation for a sweet singer, or a poet noted for grace and melody; as Shakespeare is called the swan of Avon. 3. <astronomy> The constellation Cygnus. <ornithology> Swan goose, a bird of India (Cygnopsis cygnoides) resembling both the swan and the goose. Swan shot, a large size of shot used in fowling. Origin: AS. Swan; akin to D. Zwaan, OHG. Swan, G. Schwan, Icel. Svanr, Sw. Svan, Dan. Svane; and perhaps to E. Sound something audible.

| Swan-Ganz catheter | <equipment> A special haemodynamic monitoring device (long thin catheter) that is introduced into a large vein (in the neck, chest or groin) and advanced through the right heart to the pulmonary artery. Measurements of cardiac function and blood pressure can be made with this device that can greatly increase the physician's diagnostic ability and provide a way to monitor the patients response to different medications. May be used to diagnose pulmonary hypertension. (19 Jan 1998) |
| swan-neck deformity | Hyperextension of the proximal interphalangeal joint with flexion of the distal interphalangeal joint of the finger. (05 Mar 2000) |
| swanny | Swanlike; as, a swanny glossiness of the neck. Source: Websters Dictionary (01 Mar 1998) |
| catheterization, swan-ganz | Placement of a flow-directed catheter (developed by cardiologists swan and ganz) for measuring pulmonary arterial pressures. The catheter is introduced into the venous system via the basilic, internal jugular, or subclavian vein, and is guided by blood flow into the superior vena cava, the right atrium and ventricle, and into the pulmonary artery.
