DEFINITION

Classification: 600/490

Force applied against skin to close blood vessel:

(under subclass 485) Subject matter wherein pressure is applied against skin overlying a blood vessel to close the

latter.

(1) Note. As is well known, the pressure which must be applied to skin overlying an artery to stop blood flow (and the occurrence of Korotkoff sounds associated therewith) is recorded as the systolic pressure within the artery.
