Acupressure

Broad, mild pressure, 30–45 seconds.

When not to press: Skip if pressing makes it hard to breathe.

About 30–90 seconds is the usual window, unless the step above is shorter. Stop if pain, dizziness, or anything unusual shows up.

Licensed practice only

Needle depth, angle, electroacupuncture

Textbook language for students. Not instructions. A cun is a body-inch on that person, not a ruler inch. Do not needle yourself.

Depth

Oblique toward the spine, commonly 0.5–0.8 cun.

Angle

Oblique medial.

Electroacupuncture

Introductory charts rarely assign a standard electroacupuncture setting here. Clinics that use current choose frequency and intensity for that person. No milliamp figure is given, because copying one would be misleading.
