| Which regulations control waste anaesthetic gas and volatile agents? |
|
Definition
-Control of Substances Hazardous to Health Regulations
-Heath and Safety at Work Act |
|
|
Term
-Control of Substances Hazardous to Health Regulations
-Heath and Safety at Work Act |
|
Definition
| this legislation requires that there is suitable provision for the removal of environmental contaminents in the work place |
|
|
Term
| What is anaesthetic waste? |
|
Definition
volatile agents
nitrous oxide |
|
|
Term
| Occupational Exposure Standards (OES) |
|
Definition
-indicate the levels that are considered acceptable for the working environment
-specified in ppm |
|
|
Term
| OES for halothane, isoflurane, N2O |
|
Definition
halothane 10ppm
isoflurane 50ppm
N2O 100ppm
Good working practice to keep within 50% of these |
|
|
Term
|
Definition
removal of anaesthetic waste products from the environment, to ensure environmental contamination is within OES limits
-may be active or passive |
|
|
Term
|
Definition
| uses a fan to draw exhaled or surplus FGF to outside the building where it is diluted w. air outside |
|
|
Term
| what must be considered when using active scavenging? |
|
Definition
-the fan must not remove FGF to the patient before it can be exhaled
-the vent outside must be suitable distance from windows and doors so the waste is not drawn back into the building |
|
|
Term
| air break / receiver in active scavenging |
|
Definition
used to prevent negative P being applied to the patient and removal of FGF
-exhaled gases are diluted in the receiver w. room air and removed by the fan to outside |
|
|
Term
| what anaes. waste is removed by active scavenging? |
|
Definition
|
|
Term
|
Definition
| does NOT use a fan system but relies on the expiratory efforts of the patient |
|
|
Term
| passive scavenging methods |
|
Definition
-via a long tube to outside
-via an absorbant / AC |
|
|
Term
| passive scavenging via a tube |
|
Definition
-attach a length of tube to the exp. valve of the breathing system and vent to outside the building
-ensure not too long or kinked or the exp. effort of the patient will be increased |
|
|
Term
| what anaes. waste is removed by passive scavenging via a tube? |
|
Definition
|
|
Term
| passive scavenging via an absorbant |
|
Definition
-volatile agents in exhaled breath absorbed by passing the gas through AC
-weigh the canister to gauge the capacity / volume saturate
NB: organic compounds in the atmosphere will be absorbed if left uncovered (and hence decr. the working life) |
