Term
| IN AN OPEN INTERFACE SPILLAGE WILL OCCUR IF THE VOLUME OF A SINGLE EXHALED BREATH EXCEEDS WHAT? |
|
Definition
| THE CAPACITY OF THE RESERVOIR. |
|
|
Term
| WHY DOES FLOW MATTER WITH OPEN INTERFACES? |
|
Definition
| FLOW CHARACTERISITCS OF THE SYSTEM ARE IMPORTNANT BECAUSE GAS LEAKAGE CAN OCCUR LONG BEFORE THE VOLUME OF WASTE GAS EQUALS THE RESERVOIR VOLUME IF SIGNIFICANT TURBULENCE OCCURS WITHIN THE INTERFACE. |
|
|
Term
| WHICH SYSTEM INCREASE THE RISK OF POLLUTION? |
|
Definition
| OPEN/PASSIVE SYSTEM. YOU WOULD RATHER HAVE AN OPEN/ACTIVE SYSTEM. |
|
|
Term
| HOW DOES THE CLOSED INTERFACE COMMUNICATE WITH THE ATMOSPHERE? |
|
Definition
|
|
Term
| CLOSER INTERFACES MUST HAVE WHAT? |
|
Definition
| A POSITIVE PRESSURE RELIEF VALVE TO VENT EXCESS SYSTEM PRESSURE IF OBSTRUCTION OCCURS DOWNSTREAM FROM THE INTERFACE. THEY ALSO NEED TO HAVE A NEGATIVE PRESSURE RELIEF VALVE TO PROTECT THE BREATHING SYSTEM FROM SUBSTMOSPHERIC PRESSURE IF AN ACTIVE DISPOSAL SYSTEM IS USED. |
|
|
Term
| IS A RESERVOIR REQUIRED FOR A CLOSED SYSTEM? WHEN DO YOU NEED A RESERVIOR WITH A CLOSED SYSTEM? |
|
Definition
| NO. IF USING A CLOSED/ACTIVE SYSTEM YOU NEED A RESERVOIR. |
|
|
Term
| WHAT TYPE OF VALVE IS MANDATORY FOR CLOSED INTERFACES? |
|
Definition
|
|
Term
| IS A NEGATIVE PRESSURE EVACUATION SYSTEM USED WITH A CLOSED INTERFACE? |
|
Definition
|
|
Term
| WHEN IS CLOSED INTERFACE USED WITH? ACTIVE OR PASSIVE? |
|
Definition
|
|
Term
| WHEN DOES THE POSITIVE PRESSURE RELIEF VALVE OPEN WITH A CLOSED INTERFACE? |
|
Definition
|
|
Term
| FOR A CLOSED INTERFACE: POSITIVE AND NEGATIVE PRESSURE RELIEF HOW DOES THE OPERATOR MAINTAIN CORRECT INFLATION? |
|
Definition
| BY ADJUSTING THE VACUUM CONTROL VALVE. |
|
|
Term
| IN A CLOSED SYSTEM IF SYSTEM PRESSURE IS MORE NEGATIVE THAN 0.5CMH20 WHAT HAPPENS TO ROOM AIR? |
|
Definition
| IT IS ENTRAINED THROUGH THE NEGATIVE PRESSURE RELIEF VALVE. |
|
|
Term
| EFFECTIVENESS IN PREVENTING SPILLAGE OF OPEN INTERFACE DEPENDS ON WHAT 2 THINGS? |
|
Definition
| VOLUME OF THE RESERVOIR, FLOW CHARACTERISTICS WITHIN THE INTERFACE. |
|
|
Term
| EFFECTIVENESS IN PREVENTING SPILLAGE OF THE CLOSED INTERFACE DEPENDS ON WHAT 5 THINGS. |
|
Definition
| 1) ON THE RATE OF WASTE GAS INFLOW 2) THE EVACUATION FLOW RATE 3) THE SIZE OF THE RESERVIOR 4) LEAKAGE OCCURS WHEN RESERVOIR BAD BECOMES FULLY INFLATED AND THE PRESSURE INCREASES SUFFICIENTLY TO OPEN THE POSITIVE PRESSURE RELIEF VALVE. |
|
|
Term
| WHAT DOES GAS DISPOSAL ASSEMBLY CONDUIT DO? |
|
Definition
| CONDUCTS WASTE HAS FROM THE SCAVENGING INTERFACE TO THE GAS DISPOSAL ASSEMBLY. IT SHOULD BE COLLAPSE PROOF. IT SHOULD RUN OVERHEAD, IF POSSIBLE TO PREVENT ACCIDENTAL OCCLUSIONS. |
|
|
Term
| FOR AN ACTIVE GAS DISPOSAL ASSEMBLY WHAT SERVES AS THE MECHANICAL FLOW INDUCING DEVICE THAT REMOVES THE WASTE GASES? |
|
Definition
|
|
Term
| GOW A GAS DISPOSAL ASSEMBLY AN INTERFACE WITH WHAT TYPE PF PRESSURE RELIEF VALVE IS MANDATORY? |
|
Definition
| NEGATIVE PRESSURE RELIEF VALVE |
|
|
Term
| WITH A GAS DISPOSAL ACTIVE ASSEMBLY A RESERVOIR IS DESIRABLE AND THE LARGER THE RESERVOIR THE ___ THE SUCTION FLOW RATE? |
|
Definition
|
|
Term
| FOW A GAS DISPOSAL PASIVE ASSEMBLY WHAT VALVE IS MANDATORY? |
|
Definition
|
|
Term
| WHAT ARE 3 HAZARDS WITH GAS DISPOSAL PASSIVE ASSEMBLY? |
|
Definition
| POSITIVE PRESSURE ADDED TO BREATHING CIRCUIT. EXCESS NEGATIVE PRESSURE ADDED TO BREATHING CIRCUIT. FIRE D/T OXYGEN ENRICHED GAS BEING PUMP TO MACHINE ROOMS IN HOSPITALS AND THEN VENTED TO ATMOSPHERE. |
