My commuting partner got taken out.

[7rider]

so what are his injuries at this point? is it the concussion that is the problem?
is he still on a ventilator?

He was taken off the ventilator, but has supplemental oxygen via a mask at this point.
Injuries are:
Head injuries (bleeding and bruising on the brain). This remains the biggest problem.
Broken rib
Broken collar bone.
Broken sinus (?) bone.
Various and assorted bruises and bumps
Pneumonia - not an injury, but developed in the ICU.
