The oximetry test
The oximetry test measures the haemoglobin saturation, i.e. the percentage of the blood
haemoglobin bearing oxygen. The test can be performed at rest or during/after a light
exercise phase (cycling, jogging).
This test is not intended for measuring the oximetry during exercise tests. For this use,
see chapter
Exercise testing .
The test is completely automatic.
The measured parameters are:
SpO
2
Haemoglobin saturation
HR Heart rate

1. Connect the pulse oximeter to auxiliary RS232 port on the back of the Quark PFT.
2. Connect the probe to finger or ear of the Patient (different probes are available).
3. Select
Oximetry from the Test menu and wait for the green led is prompted on the
right side of the screen.
4. In the first part of the test the HR and SpO
2
values, together with a
plethysmographic graph, are displayed. The graph monitors the quality of the
signal.
5. Wait for an acceptable quality of the real-time trace and press F2 or the Start
button to start the data acquisition.
6. Every 5 seconds, the HR and SpO
2
values are stored.
7. After the test, press F3 , so that the software displays the graphs and the measured
parameters.
