METHOD OF MONITORING VENOUS OR ARTERIAL PRESSURE

摘要

A method of monitoring venous or arterial pressure with the aid of an elongated element comprising a blood pressure transmitting vehicle positioned in a body lumen. The elongated element may be a catheter, piezoelectric transducer means carried in the catheter, a coaxial cable, or other sensing means, which may or may not have a lumen therethrough but which may be connected to apparatus for indicating or recording central arterial pulse wave forms and other heart actions. The monitoring of venous or arterial pressure may be carried on during the advancement of the distal end of the element from the point of entry to its desired ultimate position, as well as thereafter.
