Location
On the chest, in the third intercostal space, 2 cun lateral to the anterior midline.
How to locate: With the patient supine, find the sternal angle, where the second rib joins the sternum, and count the intercostal spaces down beside the sternum to the third. The point is in the third intercostal space, 2 cun lateral to the midline, level with CV18.
Distances are in cun, a proportional unit — how to measure.
