|
Definition
APL AND VENTILATOR SPILL VALVE. |
|

|
|
Term

|
Definition
NITROUS OXIDE 25PPM, HALOGENATED AGENTS 2PPM, 0.5PPM FOR HALOGENATED GASES IF NITROUS OXIDE IS ALSO BEING USED. |
|
|
Term
DESCRIBE A PASSIVE SYSTEM? |
|
Definition
WEIGHT OF GAS WILL FORCE AIR OUT. |
|
|
Term
DESCRIBE A ACTIVE SYSTEM? |
|
Definition
|
|
Term
WHAT 2 BREATHING CIRCUITS CAUSE CONTAMINATION? |
|
Definition
JACKSON-REES (MAPELSON TYPE F) AND MODIFICATION OF MAPLESON E REBREATHING CIRCUIT. BOTH ARE DIFFICULT TO SCAVENGE. |
|
|
Term
WHAT ARE 5 COMPONENTS OF THE SCAVENGING SYSTEM? |
|
Definition
GAS COLLECTING ASSEMBLY, TRANSFER MEANS, SCAVENGING INTERFACE, GAS-DISPOSAL ASSEMBLY TUBING, AND ACTIVE OR PASSIVE GAS-DISPOSAL ASSEMBLY. |
|
|
Term
WHAT IS THE MALE ADAPTER SIZE ON TRANSFER MEANS TUBING AND WHAT IS THE RATIONALE BEHIND THAT? |
|
Definition
30MM. PREVENTS IT FROM BEING MISPLACED WITH BREATHING CIRCUIT. |
|
|
Term
WHAT SHOULD THE SIZE BY OF A GAS DISPOSAL ASSEMBLY TUBING? |
|
Definition
SHORT, STIFF, AND NON COMPLIANT. |
|
|
Term
FOR A SCAVENGING INTERFACE IS NO VALVES ARE PRESENT WITH IT BE OPEN OR CLOSED? |
|
Definition
OPEN TO HAVE + PRESSURE RELEASE. |
|
|
Term
THE ONLY INTERFACE THAT HAS TO HAVE A NEGATIVE RELEASE VALVE IS WHAT TYPE OF SYSTEM? |
|
Definition
A VACCUM SYSTEM WHICH IS ACTIVE |
|
|
Term
THE SCAVENGING SYSTEMN CAN BE EITHER ___ OR ___. |
|
Definition
|
|
Term
WHAT DOES AN OPEN SCAVENGING SYSTEM MEAN? |
|
Definition
|
|
Term
WHAT DOES A CLOSED SCAVENING SYSTEM MEAN? WHAT DOES IT REQUIRE? |
|
Definition
IT IS CLOSED TO THE OUTSIDE ATMOSPHERE AND REQUIRES NEGATIVE AND POSITIVE PRESSURE RELIEF VALVES. |
|
|
Term
WHAT DOES A RESERVOIR DO? |
|
Definition
IT IS EITHER A CHAMBER OR BAG THAT ACCEPTS WASTE GAS OVERFLOW WHEN THE CAPACTIY OF THE VACUUM IS EXCEEDED |
|
|
Term
WHAT DOES THE GAS COLLECTING ASSEMBLY DO? |
|
Definition
CAPTURES EXCESS ANESTHETHIC GAS AND DELIVERS IT TO THE TRANSFER TUBING. IS IS VENTED THROUGH THE APL AND VENTILATOR SPILL VALVE. IN SOME MACHINES THE VENTILATOR DRIVE GAS IS VENTED THROUGH THE SCAVENGE SYSTEM. THIS CAN OVERWHELM THE SCAVENGING SYSTEM. |
|
|
Term
PRESSURE DOWNSTREAM OF THE GAS COLLECTING SYSTEM SHOULD BE KEPT BETWEEN WHAT? |
|
Definition
-0.5 AND + 3.5 CM H20. ADD UP TO + 15CM H20 DURING SCAVENGE OBSTRUCTION. |
|
|
Term
WHAT DOS TRANSFER MEANS DO? |
|
Definition
CARRIES EXCESS GAS FROM THE GAS COLLECTING SYSTEM TO THE SCAVENING INTERFACE. |
|
|
Term
OCCLUSION OF TRANSFER MEANS CAN CAUSE WHAT |
|
Definition
BREATHING CIRCUIT PRESSURE TO INCREASE AND CAN RESULT IN BAROTRAUMA. |
|
|
Term
IS THE TRANSFER SYSTEM UPSTREAM OR DOWNSTREAM FROM PRESSURE BUFFERING FEATURES OF THE SCAVENGING INTERFACE? |
|
Definition
|
|
Term
WHAT DOES THE SCAVENGING INTERFACE PROTECT? |
|
Definition
PROTECTS THE BREATHING CIRCUIT OR VENTILATOR FROM EXCESSIVE POSITIVE OR NEGATIVE PRESSURES THAT MAY BE GENERATED IN THE SCAVENGE SYSTEM. |
|
|
Term
WHAT TYPE OF PRESSURE RELIEF IS MANDATORY IRRESPECTIVE OF THE TYPE OF DISPOSAL SYSTEM? |
|
Definition
POSITIVE PRESSURE RELIEF. |
|
|
Term
IF THE INTERFACE IS ACTIVE WHAT PRESSURE RELEIF IS NECESSARY TO PROTECT FROM EXCESSIVE SUBATMOSPHERIC PRESSURE? |
|
Definition
NEGATIVE PRESSURE RELIEF. REMEMBER ACTIVE REQUIRES A NEGATIVE PRESSURE RELIEF VALVE. |
|
|
Term
DOES THE OPEN INTERFACE CONTAIN VALVES? |
|
Definition
NO. IT IS OPEN TO ATMOSPHERE. IT ALLOWS BOTH POSITIVE AND NEGATIVE PRESSURE RELIEF THROUGH HOLES AT THE TOP OF THE CHAMBER. |
|
|
Term
WHAT SHOULD OPEN INTERFACE BE USED ONLY WITH? |
|
Definition
ACITVE DISPOSAL SYSTEMS THAT USE A CENTRAL EVACUATION SYSTEM. |
|
|
Term
WHAT DOES OPEN INTERFACE SYSTEM REQUIRE? |
|
Definition
A RESERVOIR BECASUE WASTE GASES ARE INTERMITTENTLY DISCHARGED IN SURGES AND FLOW FROM EVACUATION SYSTEM IS CONTINUOUS. THE OPEN INTERFACE IS SIMPLE, BUT MAY POLLUTE THE ATMOSTPHERE IS RESERVOIR DOES NOT HAVE SUFFICIENT VOLUME. |
