Unpacking and Inspection
The CDI OneView System has been packaged to prevent shipping damage. The cartons
contain a Display (with a Display cable), Core (with a power cable) and Calibrator. The
Display Bracket, Core Bracket, Calibrator Bracket, BPM Bracket, Calibration Gas Bottles,
BPM Probes, H/S Probes, Calibrator Cable, External Data Modules, Flow Interface
Module, and Flow Sensor are packaged separately. Be sure to keep all cartons and
llers.
If any items are missing, or if there is visible damage to any of the contents, notify
the Customer Administration Department at Terumo Cardiovascular (800) 521-2818
promptly. They will provide instructions and make arrangements to resolve the problem.
Calculations
The following calculations are used to display each value. The calculated output
depends on the availability and accuracy of the measured inputs.
