I am currently on the defibrillator upgrade mission and I am right outside the room that has the item I need for the quest. For some reason though and I can't for the life of me figure out why the door will not open for me. I have watched a couple online tutorial videos and everytime they just walk up to the door and it just opens for them.
I have killed all the enemies in the area (unless maybe one is bugged?), picked up all the items I can see and still no luck.
Here are some screenshots to show where I am.

This is the door that will not open.
And the general area that I am in:

I ran the following rooms leading up to the defib room quickly - not pausing to wander around! Shoot / kill / shoot / kill - do not hesitate, move fast. The door with the security cam that previously would not let me in? NOW IT OPENED. Voila! So it must be a timing issue. FYI - I tried to open the door from the save that I made just after I killed the boss and no luck. For me, It only worked by killing the boss again.
