FIGURE 3-27 Spirometry: Pressure-Flow Loop
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 3-25), flow -
volume loop (see FIGURE 3-26) and pressure - flow loop (see FIGURE 3-27). Loops data comes from
pressure and flow data. Only one loop displays at a time.
The Spirometry tab displays four softkeys: Loop Type, Show Reference, Save Loop, and Review
Loops.
3.5.1 Loop Type
Select Loop Type to display pressure - volume loop, flow - volume loop or pressure-flow loop on the
Spirometry screen. Default loop type is pressure - volume loop.
