Methods of arterial pressure monitoring

Abstract

Methods of monitoring arterial blood using an arterial line tube positions adjacent to a groin sheath, as part of a surgical intervention. Described herein are methods and apparatuses (e.g., systems) for introduction of an arterial line tube for contemporaneous and sensitive blood pressure monitoring along with other instrumentation in the course of a therapeutic intervention through a femoral artery, affording improved monitoring results.

AI Technical Summary

Benefits of technology

The patent describes a method for measuring blood pressure in a continuous way, which reduces interruptions caused by the insertion of a device. This is possible because the arterial line tube remains in place after the first procedure, preventing the disruption of arterial monitoring. The use of two sequential groin sheaths allows for easy placement of the arterial line tube and provides better stability during the procedure. The arterial line tube is small enough to be easily removed with minimal pressure, and it is important for maintaining adequate blood flow during the procedure.

Problems solved by technology

Performing these functions within the small dimensions of an artery can cause other instrumentation to jar or erratically displace an arterial line used for the hemodynamic monitoring, and may affect the ability to retain the arterial line after the other instrumentation is withdrawn.
