Unrestricted area
Traffic not limited, if in scrubs you need a lab coat.
Semi restricted area
Traffic limited, so scrubs and cap needed
Restricted area
Traffic only to necessary personnel. Unwrapped sterile supplies
Standard OR temp
68-75 degrees F
Hypothermia associated with : increased wound infection, impaired coagulation, increased blood loss, prolonged hospitalization
Standard humidity levels OR
30-55%
<30- increased fire, alters sterile indicator strip, increased infection risk (flying debris)
> 55%- increased risk of infection, mold/mildew, uncomfortable for staff
Ventilation in OR?
Engineered to decrease turbulent flow and be unidirectional. Not part of waste anesthesia gas system,
Maintains a small amount of positive presure
Fresh air introduced near ceiling with return near floor
25 air exchange/hr, remove 90% particles in air
Fresh air standard for OR
80/20 mixture of recycled/fresh air
Needed air exchanges/hr
25
Necessary percentage for high efficiency particulate filters
90%
Normal OR dB level
75-90
Voice needs to be what dB level to be heard
20 above background
Ionizing radiation
Enough energy to detach e from atoms, nuclear decay, gamma rays and X-ray, UV light
Appropriate radiation exposure
ASARP (as little as reasonably possible)
Law of inverse square
Amount radiation changes inversely with distance
Macroschok
100-300 causes Vfib Current applied through body through skin
