Breathing systems & circuits: choose the circuit and set the flow

The canonical circuits SAQ — the Mapleson arrangement-to-efficiency logic (Magill at minute ventilation, Bain at 1.5 to 2 times, T-piece at 2.5 to 3 times spontaneous), the Bain unsuitability under 20 kg, the circle placement rules with 250 to 500 mL flows, the AAGBI leak test at 20 to 60 cmH2O, and the inspired-CO2 absorbent-change rule.
