Sergei #Skripal & his daughter remain in CRITICAL condition, but the police officer now is "stable & conscious."

My read: the Russians likely had respiratory compromise due to the NERVE AGENT and suffered anoxic brain injury.😳 1/…
BBC reports the nerve agent was not VX and likely is "rarer" than Sarin. Making & delivering nerve agents requires CONSIDERABLE infrastructure, so the more rare the agent, the easier to confirm which country (#Russia), even which laboratory, made it.🤔

If the NERVE AGENT blocks signals to muscles, the victim stops breathing (respiratory arrest), which won’t allow enough oxygen to get to vital organs (“anoxic” brain injury).

Unless resuscitated quickly, the victim can suffer CATASTROPHIC brain injury.😳

Thankfully, the police officer now is “stable and conscious,” likely b/c he was exposed to a lower dose of the nerve agent and was resuscitated (ventilated / given oxygen) quickly.

Based on public info, I suspect that the prognosis for the Russians is grim, unfortunately.
Full disclosure, I’ve spent years working on a treatment for viral biological weapons, including #Ebola. Hence, I have some expertise in the development of chemical and biological weapons, as well as in countermeasures against them. 👩‍⚕️ 💉💊🔬
