O2 Saturation (optional)
The O
2
Saturation event is useful to check the quality of SpO
2
signal acquired by the on-
board Oxymeter (if available) during the test.
O2 Saturation during the test
1. Start with normal Exercise test and begin the memorisation of breath values (F2).
2. Select O
2
Saturation from Test/Event...
3. As soon as 5 or 6 complete pulses have been acquired press F3 to stop the
acquisition.
Spirogram
The spirogram event allows to display and store the volume/time plot.
Spirogram during the test
1. Start with normal Exercise test and begin the memorisation of breath values (F2).
2. During a steady state select Spirogram form Test/Event...
3. Acquire volume/time plot until the window is filled and press F3 to stop the
acquisition.
View the events after the test

concentration at the equilibrium and the

It's a particular feature with which the user can check and save some parameters (CO
2
output, O
2
concentration and volumes) in Ascii file format in a archive apart at a
sampling rate of 25 Hz.
