later)
Spirometry loops reflect patient lung function and ventilation. They also indicate other related
parameters such as compliance, over-inflation, breathing system leak, and airway blockage.
The system provides three types of spirometry loops: pressure - volume loop (see FIGURE 3-18), flow -
volume loop (see FIGURE 3-19) and pressure - flow loop (see FIGURE 3-20). Loops data comes from
pressure and flow data. Only one loop is displayed at a time.
The Spirometry tab displays four softkeys: Loop Type, Show Reference, Save Loop, and Review
Loops.
3.5.1 Loop Type
The Loop Type selection is used to select pressure - volume loop, flow - volume loop or pressure-
flow loop to display on the Spirometry screen. Default loop type is pressure - volume loop.
