Overview of Cardiac Measurements

The Cypress system provides a range of cardiac measurements and derived
calculations for diagnostic ultrasound. There are two types of calculations:
General: Simple general measurements, such as a distance or area, that are
not associated with a particular calculation and are not saved to the Patient
Report. Table 26 lists the general measurements by each mode type.
Specific: Measurements that are a part of a formulaic calculation. These typ-
ically involve multiple measurements and the calculation of a clinical index
such as Ejection Fraction. These calculations are saved in the Patient
Report. Table 27 on page 6-3 lists the specific calculations by each mode
type.
NOTE General measurements are designed to be a quick way to perform
calculations that you do not assign to a report.
