- Figure 1.
Vectors of microbial contamination in the AW.
- Figure 2.
A typical anesthesia machine with architectural/design complexity, making cleaning and disinfection between surgical procedures very challenging.
- Figure 3.
Location of condom-like protective covers: (A) vaporizer control dials, (B) oxygen flowmeter control, (C) electrical medical record control mouse, and (D) breathing circuit pressure control valve (APL valve).
- Figure 4.
Preliminary study to assess wrap barrier effectiveness. Growth on SBA after 48-hour incubation (A) outside of plastic cover after inoculation with S epidermis, (B) inside of plastic cover after inoculation with S epidermis, and (C) knob covered after inoculation with S epidermis.
