INTRODUCTION

English translation pending.

CORE DEFINITION

A classical pulse quality in Chinese medicine: the pulse is easily felt at the light level, thin and soft, and becomes weak under heavy pressure, like a wad of soaked cotton floating on water. It indicates deficiency, especially floating yang from yang deficiency or depletion of essence and blood, and it is associated with dampness encumbering the spleen. The body is waterlogged while qi and blood are not full, so the person feels heavy and listless, a presentation common in the damp season or in those with weak spleen and heavy dampness. It must be distinguished from the hollow and scattered pulses.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Read the Saturation: treat softness plus heaviness as a system loaded with something it cannot move - Separate Float from Force: a finding at the surface does not by itself make a surface pattern - Check the Reserves: ask whether an underlying deficit, not the load, is the real driver

Anchor fast decisions

Dampness adds load without adding substance, so tissue retains fluid and loses tone; the vessel walls soften and the pulse gives way under pressure even though it is easily felt at the surface. Because the same softness can come from qi or blood deficiency, the quality only becomes interpretable when read alongside signs such as fatigue, cold intolerance or spontaneous sweating. Treating the surface while ignoring the depletion makes matters worse, since the body has no reserve to spend on the treatment.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Feel the pulse lightly, then press firmly and note how quickly it gives way. 2. Check for accompanying fatigue, cold intolerance or spontaneous sweating. 3. Compare against flooding and excess pulses to rule out the opposite pattern. 4. Ask whether the surface finding is driven by an underlying deficit. 5. Reassess after supportive treatment rather than pushing the surface harder.
