Instructions for TSB # 20a - (for units fitted with Neoflow TM only)

For units with Neoflow, SW 4.10 allows for optional pulse threshold settings varying between 1 lpm and 5 lpm. 5 lpm is the standard default. It is recommended that the pulse threshold be kept at 5 lpm unless the sound compensation at 5 lpm is inadequate. Other problems such as high PEEP alarms and FiO2 deviations might be more sensitive at lower pulse threshold
