Spirometry
Use the Spirometry menu to:
• Set the loop type.
• Adjust the loop scaling.
• Access the Spirometry Setup menu.
• Save a loop to memory.
• View a saved loop.
• Erase a saved loop.
There are three types of spirometry loops: Pressure-Volume (P-V),
Flow-Volume (F-V) and Pressure-Flow (P-F). The spirometry loops
show in the spirometry window and can be set to show alongside the
waveforms as the split screen.
