Closed-chest cardiac massage results in a marked increase in intrathoracic pressure and unusual patterns of blood flow. Among the physiological consequences of these changes appears to be a marked increase in intracranial pressure associated with chest compression as documented by the following patient case studies. While temporary, the marked nature of this rise in intracranial pressure suggests that the technique of closed-chest massage may, in itself, be responsible for clinically significant alterations in cerebral hemodynamics.
