Performing and Reviewing Calculations

Notes—

•If you plan to use monitored parameter values in Calculations, be sure that when you are configuring parameters, you assign the parameter the same label that is used in Calculations. For example, ABP should be used instead of ART because ABP is the label used by Calculations.

•When you enter the Task Window, the Calculation time will be the last C.O. time or the current time, depending on how the monitor is configured. If C.O. time is used, values stored more than one minute before that time, are automatically entered. Values up to and including 30 minutes before the calculation time will be used. The most recent values occurring before the calculation time will be used for height, weight, and head circumference calculations.

•Displayed values may have been automatically stored or manually

entered using the keypad or Resample Vitals. .

•You must verify that all input values are appropriate for your patient prior to performing calculations.

•If you enter pressure values manually, you must enter all three parts - systolic, diastolic, and mean - in order for calculations to be performed for that pressure reading.

BSA Formula The patient monitors provide both the Boyd and Dubois formulas for the calculation of body surface area (BSA). The default configuration for all patients is the Boyd formula. All calculation results that use BSA are indexed to the selected formula. The Hemodynamics and Oxygenation Calculations Task Windows which display BSA use the label BSA(B) for the Boyd formula and BSA(D) for Dubois. To change the default [for example to use Dubois for adults and keep Boyd for neonates], the appropriate selection must be made in the Patient Data Configuration Task Window. See your Philips Service Engineer or biomedical engineering department for assistance in making a change.
