Comprehensive Guide to Arterial Pulse Examination: Techniques, Physiology, and Clinical Significance Arterial Pulse Examination: Comprehensive Clinical Summary

Overview

Arterial pulse examination is a fundamental clinical skill that provides critical insights into cardiovascular function and hemodynamic status. Despite advances in imaging, it remains essential for diagnosis and clinical assessments. The pulse is a pressure wave generated by left ventricular ejection during systole, traveling faster (approximately ten meters per second) than blood flow (approximately zero point three to zero point five meters per second), and serves as a direct index of cardiac performance.

Technique and Peripheral Pulses

Examination should be systematic and bilateral to detect asymmetry (e.g., coarctation, aortic dissection). Key arteries include:

Radial: Most common site for rate and rhythm.

Carotid: Best for assessing character and volume; located in the carotid triangle.

Femoral: Midpoint between ASIS and pubic symphysis.

Dorsalis pedis: Proximal first web space; absent in approximately ten percent of healthy individuals.

Posterior tibial, popliteal, brachial, axillary, subclavian, superficial temporal: Each with specific landmarks.
