What FGF is used in a bain circuit for spontaneous respiration?
|
100-300 cc/kg/min or 1.5-3x MV
|
|
|
What FGF is used in a bain circuit for controlled respiration?
|
70-100 cc/kg/min
|
|
|
What is a problem with the Bain circuit?
|
Possible disconnect of inner FGF hose may go unnoticed
|
|
|
How is the Bain circuit tested?
|
Pethick test: close APL valve, flush w/ O2 until resevoir is full. Then open patient end -> should lead to collapse of reservoir. Bag remains inflated w/ disconnect
|
|
|
What is the difference b/t a Mapleson D and a Mapleson F (Jackson-Rees)?
|
Mapleson F has an opening/low pressure valve at end instead of APL -> decreased resistance/WOB
|
|
|
When is the Mapleson F used?
|
Peds
|
|
|
What FGF is used w/ a Mapleson F?
|
2-3 MV
|
|
|
What are the components of a semi-closed circle absorber?
|
Inspiratory/expiratory tubing, unidirection inspiratory/expiratory valves, CO2 absorber, resevoir bag, APL
|
|
|
Describe the inspiratory/expiratory tubing in a semi-closed circle absorber
|
Corrugated, 22mm diameter, 400-500cc internal volume
|
|
|
Describe the resistance of the resevoir bag in a semi-closed circle absorber
|
30-50 cm H2O at < 1.5L, 35 cm H2O at 3L (compliance increases as volume expands)
|
