Pulse-Taking and Palpation
Changes of pulse condition may reveal pathological changes of the body. With palpation the site and condition of disease are known.

Traditional Chinese medicine has evolved a well-defined method for taking the pulse and interpreting the results.  There are three positions for pulse-taking, namely, cun, guan and chi. The guan is the region opposite the styloid process of the radius.  Between the guan and the wrist joints is the cun.  On the other side is the chi.  On pulse-taking three fingers are used.  First the middle finger locates the guan, then the index finger finds the cun while the ring finger finds the chi with gentle, moderate and heavy pressure.
On the left hand, the cun, guan and chi correspond to the heart, liver and kidney respectively. On the right hand, the cun, guan and chi reflect the condition of the lung, spleen/stomach and kidney ( gate of life) respectively.
Method of pulse-taking: The patient’s hand should be placed palm up.  The tip of the index, middle and ring fingers put on the place where radial artery throbs.
A normal pulse is rhythmic, stable, even and forceful.  It is neither superficial nor deep, neither wide nor narrow.  It has a frequency of about 4~5 beats per breath in adults.  In children the pulse is usually about 7~8 beats.
Changes of pulse condition is usually caused by cardiac contractility, speed and rhythm of blood flow, blood volume, angiorhigosis and vascular resistance.
