Term
| T/F. with Mapleson systems there should be NO rebreathing of exhaled gases |
|
Definition
| True. As long as FGF are high enough (2-3 times minute ventilation) |
|
|
Term
| How can we turn a semi-closed (circle) system into a completely closed system? |
|
Definition
| turn FGF down to < 0.5 L/min |
|
|
Term
| Do semi-open systems (Mapleson) neutralize CO2 with an absorbant? |
|
Definition
|
|
Term
| Do Mapleson systems have a reservoir bag (AMBU)? |
|
Definition
| Yes, except for Mapleson E |
|
|
Term
| semi-closed systems contain ___ unidirectional valves. What are they? |
|
Definition
| 3. inspiratory, expiratory, and APL |
|
|
Term
| T/F. Mapleson systems are ALL semi-open systems. |
|
Definition
|
|
Term
| T/F. Mapleson systems are all NON-REBREATHING systems. |
|
Definition
|
|
Term
| Do Mapleson systems have unidirectional valves? Why does this matter? |
|
Definition
| No (except for APL). This renders work of breathing LOW |
|
|
Term

|
Definition
| D; coaxial (tube within tube) |
