But for some reason you are insisting that ashphyxia was the 'only' cause of death? You must have a reason for insisting on that. You probably want to fit something into you theory. What exactly?
You should ask this questoon to Dr. Meyer, for it was he who listed craniocerebral trauma as one of the causes of death.
Aside from that, a look at the X-ray which shows the horrific wound to JonBenet's skull should answer this question even for medical laypeople like you and me.
Her skull was split in two halves, a piece of skull bone was punched out.
There was extensive hemorrhage in the brain (scalp hemorrhage, subdural hemorrhage, and subarachnoid hemorrhage). From what I have read on medical websites, subarachnoid hemorrhage is a very serious conditon.
rashomon,
I reckon we both saying the same thing, except I am using precise technical terms.
I'll state it again, since it is clear in the autopsy report, JonBenet died from hypoxia, which is a deficiency of oxygen!
Any interruption of oxygen at any step in its path through the body can lead to
asphyxia via various mechanisms e.g.
Suffocation
Strangulation
Drowning
Inhalation of toxic chemicals
These are the most common and well understood, another mechanism is via a serious head injury.
So if JonBenet's subdural hemorrhage was significant enough in volume, it would increase the intracranial pressure, squeezing the brain. Mounting pressure would shut down the brain function, push brain material down into the
foramen magnum, the opening at the base of the skull where the spinal cord exits, causing JonBenet to lose conciousness. Now the important part is this, the part of the brainstem that controls breathing also shuts down,
respiration stops, and death follows. That is a head injury of the type inficted upon JonBenet has the ability to cause
asphyxia!
Since her skull was fractured I do not think the above asphyxiation process occurred.
But her depressed skull fracture did lead to a subdural hemorrhage, which reduces the flow or passage of oxygen, thus contributing to her death via asphyxia, which caused hypoxia.
So a strangulation and head injury both contributed towards asphyxiation.
But Coroner Meyer reckons the strangulation is the major causal factor in her death with her head injury patently being corelated in some manner, which he cannot quantify, e.g. strangulation equals no oxygen!
