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.
As a doctor, you have to be able to describe a ânormalâ heartbeat before you can appreciate anything abnormal. Medicine uses the phrase âlub-dubâ or âlub-dupâ to describe the noise the heart makes: this is what you can hear through your stethoscope. The term aims to capture the slight distinction in quality between the first and the second heart sounds. The first heart sound, or âlubâ, is generated by the atrioventricular valves closing.
