Sappiate comunque che quello di buono (e di
meno buono) che vedrete ed ascolterete è
basato su evidenze scientifiche ed esperienze
cliniche di ottima qualita’.

Inefficient. Once the bag is full during expiration,
fresh gas is vented.
Not suited for spontaneous breathing -
rebreathing is inevitable (with CO2 entering the tubing or bag) unless FGF
exceeds peak inspiratory flow rates (3xMV).
The C circuit is compact and was used for short transports before
self-inflating bags became available. Acceptable CO2 levels could be
achieved with a FGF of 2 x MV and mild hyperventilation. If the cylinder
became empty ventilation was impossible.

Mapelson Circuits
MAPLESON B AND C
They are similar in construction, with the fresh gas flow entry and the expiratory valves
located at the patient end of the circuit and reservoir bag is at the machine end of the
circuit, except that corrugated tubing is omitted in Mapleson C. They are not commonly
used in anaesthetic practice although C system may be used for emergency resuscitation.
High flow of gases is needed to prevent rebreathing of CO2 and theatre pollution is
maximum. Fresh gas flow required is equal to peak inspiratory flow rate (20-25 lit/min) to
prevent rebreathing. So there is lot of wastage of fresh gases.
