Saturation Step-Ups
Saturation step-ups are the differences in oxyhemoglobin saturation (%Hb0
2
) between adjacent
anatomical sites. These values are used as an aid in diagnosing intracardiac and great vessel
shunts.
Important: In order to calculate saturation step-ups for a patient, the ITC AVOXimeter
1000E
results for that patient must be labeled with the Patient ID (see page 27)
and the anatomical site from which the sample was obtained (see page 23).
The ITC AVOXimeter 1000E uses all measurements stored in the system for a patient when
calculating oxyhemoglobin saturation step-ups. The system searches the database for all results
for each main oximetry site for that patient, averages the results for each site, and calculates the
oxyhemoglobin saturation step-ups from the average result for each main site.
Note: Use of average readings rather than individual values improves the precision of
Saturation Step-Up calculations.
1. If needed, enter the Patient ID for which Saturation Step-Ups are to be calculated
(see page 27).
2. Display page 1 of the “Hemodynamics” menu (a submenu of , see page 8).
3. Press followed by . The Patient ID for which oxyhemoglobin saturation
step-ups will be calculated is displayed:
4. Verify that the Patient ID is correct, then press . The first page of
oxyhemoglobin saturation step-ups for the patient is displayed:
Note: The following abbreviations are used:
RA
Right Atrium PA Pulmonary Artery
RV Right Ventricle PV Pulmonary Vein
LA Left Atrium AO Aorta
LV Left Ventricle SVC Superior Vena Cava
5. Press to display the second page of oxyhemoglobin saturation step-ups for
the patient:
6. Press when done. The “Hemodynamics” menu is again displayed.
7. Press to return to the previous menu, if desired.
