Scientific Evidence for Hydrostatic Shock

TL;DR

This paper critically reviews scientific evidence for hydrostatic shock, examining physical mechanisms, historical claims, and experimental data to determine if ballistic pressure waves can cause remote injuries.

Contribution

It provides a comprehensive analysis of existing evidence and physics to assess the validity of hydrostatic shock as a real phenomenon in wound ballistics.

Findings

Hydrostatic shock involves ballistic pressure waves causing remote injuries.

Evidence for remote cerebral effects exists but is debated.

Energy transfer levels influence the observability of hydrostatic shock.

Abstract

This paper reviews the scientific support for a ballistic pressure wave radiating outward from a penetrating projectile and causing injury and incapacitation. This phenomenon is known colloquially as "hydrostatic shock." The idea apparently originates with Col. Frank Chamberlin, a World War II trauma surgeon and wound ballistics researcher. The paper reviews claims that hydrostatic shock is a myth and considers supporting evidence through parallels with blast, describing the physics of the pressure wave, evidence for remote cerebral effects, and remote effects in the spine and other internal organs. Finally, the review considers the levels of energy transfer required for the phenomenon to be readily observed.
