During a minimally invasive procedure, the surgeon will thread a balloon catheter through the femoral artery in the groin and guide it to the carotid artery in the neck. After the catheter is in place, the doctor may inflate the balloon to push open the cross-section of the carotid artery and improve blood flow. The contour of the normal carotid pulse is AABB "CD shown in Fig. 3. There is a rapid initial rise to the first inflection, 0100-12 sec. after the onset.

In Advanced Trauma Life Support (ATLS), we learned that a carotid, femoral, and radial pulse correlates to a certain systolic blood pressure (SBP) in hypotensive trauma patients. Specifically ATLS stated: Carotid pulse only = SBP 60 – 70 mmHg. Carotid & Femoral pulse only = SBP 70 – 80 mmHg.
