Comparison of the fresh gas flow requirements and resistance of the Preferential Flow System with those of the Magill system.
The fresh gas flow requirements of the Preferential Flow System have been compared with those of the Magill system in spontaneously breathing volunteers and found to be similar. A lower resistance to expiration was found with the Preferential Flow System and the effectiveness of the valveless method of flow direction was demonstrated.
