0.0 seconds – bullet impact
The bullet enters the side of the neck at ~3000 ft/s.
A temporary cavity forms: the shockwave expands tissue far beyond the actual bullet diameter.
If this cavity intersects the upper spinal cord (C1–C3) or brainstem pathways, higher brain control is instantly disconnected.
0.05 – 0.2 seconds
Neural disruption: Consciousness is cut off immediately. The face goes blank (“nobody home”).
Involuntary motor response: With higher control gone, the body produces decerebrate/decorticate posturing arms may stiffen or pull toward the torso, body goes rigid.
Victim is still technically sitting upright because muscle tone hasn’t relaxed yet and gravity hasn’t acted.
0.2 – 0.5 seconds
The heart is still pumping, but neural control of posture is gone.
Blood vessels may already be ruptured (e.g., carotid artery, jugular vein), but external bleeding hasn’t yet emerged because tissue has to tear open a path for it.
At this point the victim is unconscious, unresponsive, and neurologically “offline.”
0.5 – 1.0 seconds
External blood gushes out: pressure forces blood out of the wound, sometimes explosively.
The victim begins to collapse — either straight down or slumping sideways, depending on chair and body position.
Reflexive stiffening may persist briefly as the body falls.
1 – 5 seconds
Massive hemorrhage continues, with liters of blood lost rapidly if the carotid or jugular are completely severed.
Breathing ceases or is ineffective due to loss of neural control and/or airway destruction.
No return of consciousness is possible — damage is catastrophic.
5 – 30 seconds
Heartbeat may persist for a short period, but without coordinated brainstem control or blood volume, it becomes ineffective.
The body is now limp; any earlier stiffness fades into flaccidity.
30 seconds – 2 minutes
Circulatory collapse is complete.
Without immediate advanced intervention (and realistically even with it), survival is impossible.
