Crushing chest pain, breathlessness or a cold sweat can signal a heart emergency — call emergency services at once; do not try acupressure.
If someone collapses or is not fully conscious, call emergency services at once; do not try acupressure.

4How has it been used traditionally?

Classified as the Jing-well (Wood) point and last point of the Pericardium meridian — a historical classification, not a claim of effect.
The name joins zhong (middle, for the middle finger) and chong (thoroughfare).

From traditional texts — not a claim of effect.

5Classical text

Donguibogam (Heo Jun, 1613), Acupuncture and Moxibustion, "Zhongchong"

在手中指之端去爪甲如韭葉陷中手厥陰脈之所生爲井 …《靈樞》

① At the tip of the middle finger, in the hollow about a leek leaf's width from the nail. Where the Hand Jueyin channel arises, which makes it the Jing-well point (Lingshu).

Source tags as given in the Donguibogam: Lingshu = the Yellow Emperor's Inner Classic: Spiritual Pivot.
The garbled glyph 堛 in the Wikisource text has been corrected to 韭 (leek).
Lingshu ch.
2 only says 'the tip of the middle finger'; the leek-leaf wording is found in the Zhenjiu Jiayi Jing (vol.
3).
所生 (arises) differs from the usual 所出 (emerges) and is kept as written.
This old nail-side description is close to the WHO alternative location.
"…" marks the needling depth and moxa count, left out because they are for licensed practitioners.

6Alternative location

Beside the thumb-side corner of the middle fingernail, where a line along that nail edge meets a line along the nail base (0.1 finger-cun from the corner). WHO 2008 Remarks.

Chinese standard (2021) differs · China's 2021 standard takes the highest point of the fingertip as the main spot and the 0.1-cun spot by the thumb-side nail corner as the alternative — the same pair as WHO.
