Methods and devices to reduce damaging effects of concussive or blast forces on a subject

A method and device for reducing the damaging effects of a blast or concussive event includes applying pressure to at least one jugular vein to reduce the egress of blood from the cranial cavity during the incidence of the concussive event. Reducing blood out flow from the cranial cavity increases intracranial pressure of the cerebrospinal fluid to reduce the risk of traumatic brain injury and injuries to the spinal column. Reducing blood out flow further increases the intracranial pressure, and thereby increases the pressure of the cochlear fluid, the vitreous humor and the cerebrospinal fluid to thereby reduce the risk of injury to the inner ear, internal structure of the eye and of the spinal column. In addition, increasing intracranial pressure reduces the likelihood of brain injury and any associated loss of olfactory function.
