The pressure during expiration can be adjusted by rotating the sleeve to close or open the side resistance. With side resistance fully open, it generates 1 to 3 cmH2O of pressure. With side resistance 50% closed, it generates 3 to 7 cmH2O of pressure. With side resistance 75% closed, it generates 8 to 14 cmH2O of pressure.
