Term
| Techniques to reduce OR pollution |
|
Definition
Good mask fit
Dump anesthetic gases only to scavenger
Early discontinuation of anesthetic
Careful filling of vaporizer |
|
|
Term
|
Definition
| Single most important factor in reducing anesthetic air pollution |
|
|
Term
|
Definition
| Through the ceiling and outflow is through ports placed 6 inches above the floor |
|
|
Term
| Non- Recirculating Ventilation Systems |
|
Definition
In Most ORs
Pumps are used to pump fresh air into the OR at a rate of > than 10 exchanges per hour |
|
|
Term
|
Definition
Popular in areas of extreme climate
Air is filtered but no anesthetic gases are removed |
