Yes your right, the Dallas Presbyterian Hospital did exactly what they could, and in a manner consistent with basic precaution. I have no Quarrel with their procedures, However, the CDC and Or USAMARIID should have been dispatched immediately upon confirmation of a Level 4 Contagion Loose in the public! USAMARIID and NIH etc Have Level 4 Biocontainment suits that are portable! I will post pics below. Yes the suits being worn by the people transporting the dallas nurse were those type suits with enclosed ventilation supplies. Either PAPR or full Air bottle, like SCBA. PAPR is Powered Air Purifying Respirator.
Above link is an infectious disease PAPR system available to health care facilities.
There are a number of suits available, mostly PAPR and some actual SCBA with enlosed Air Supplies, but PAPr is sufficient, and will keep the wearer free from infection. There is a contest underway to design a suit with portable cooling unit to keep wearer cool since these suits are cumbersome and Hot, and very tough to live in for long. I would Advise N-100 Masks Minimum, full face shields, Tyvek suits or other non permeable suits, full rubber boots and gloves, taped at joints for non close care workers, IE- techs that check vitals on monitors in room, Nurses and Doctors in room with infected patient ideally should be in full PAPR gear, with 100% enclosure, clear Hoods for vision, but 100% sealed from Air. I realize Ebola is not Airborne right now, but as a precaution for the sudden mutation, and realizing the CBRN redundancy of overprotection you cannot go wrong. Also as a side note, a patient couging or sneezing could cause airborne droplets of saliva possibly tainted with blood and other body fluids to become "Airborne" in a small area, and land in your eyes, mouth, nose etc. This is known as a Border danger, IE - Border between Airborne and Bloodborne, or Bodily fluid. Just because the Nurse that becomes infected was not infected by an Airborne Contagion does not mean that she is any less infected! Little good the definition of Airborne V.S Bloodborne does her.
By the way John, Yes I saw the picture of the man with the clipboard following the PAPR suited caregivers. No he was not safe - 100%, nor will he be later - 100%! Like Kirked said in his post one has to account for human error! I would classify that as a Large human Error, sort of akin to standing next to an exposed rod of Plutonium. Very Stupid, in my opinion.
As for links, I would be glad to provide any assistance to any Doctor in BMJ for Technical Info.
Below are some general links of interest.
I will be available if more links are needed, and for consult as needed.
