Arterial access from lower extremity. The common femoral artery is the only access site used in the lower extremity. Catheters used for performing coronary angiography via the femoral artery were developed by Melvin Judkins, MD; thus, the method often is referred to as the Judkins technique. This widely used method requires separate preformed catheters for the right and left coronary arteries (see the images below).
Urethral sounds/play, sometimes called sounding, is basically inserting objects (often steel sounds and catheters) into the urethra for erotic purposes. Sounds painful and unpleasant to most, but some people get a kick out of this.
The first heart sound (lub) occurs when the atrioventricular (AV) valves close and the second heart sound (dub) is heard when the semilunar valves close. Heart conditions can be identified by variation in these heart sounds, such as a murmur. Click below to hear the bear heart sounds.
