5.4 Display Electronic Flowmeter
Gas flow can be displayed either in a standard-resolution mode or high-resolution mode.
These two resolution modes vary in scale and accuracy.
Switchover between the standard-resolution mode and the high-resolution mode can be
performed manually based on gas flow. The default is high-resolution mode.
The scale range of the standard-resolution mode is 0 to 10 L/min and that of the
high-resolution mode 0 to 6 L/min.
To select the electronic flowmeter with desired resolution, select the electronic flowmeter
area to access the [
Display Selection
] menu.
When spirometry loop and gas modules are configured, you can select to display either
spirometry loop or electronic flowmeter. In this case, select the electronic flowmeters area to
open the [
Display Selection
] menu and then select the desired spirometry loop or electronic
flowmeter.
5.5 Spirometry Loop
Spirometry loops reflect patient lung function and ventilation as well, such as compliance,
over-inflation, breathing system leak and airway blockage.
The system provides two spirometry loops: P-V (Paw-volume) loop and F-V (flow-volume)
loop. Only one loop is displayed at a time: P-V loop or F-V loop. To switch over between the
two loops, select spirometry loop area and select the desired loop. The scales of volume flow
and Paw are adjusted automatically. The following figures show an F-V loop and a P-V loop.
