20.5 Hemodynamic Calculations
20.5.1 Performing Calculations
1. In the main menu, select [
Calc >>
] → [
Hemodynamic >>
].
2. Enter values for calculation.
‹
For a patient who is being monitored, [
HR
], [
Art mean
], [
PA mean
] and [
CVP
]
are automatically taken from the currently measured values. If you just have
performed C.O. measurements, [
C.O.
] is the average of multiple thermodilution
measurements. [
Height
] and [
Weight
] are the patient’s height and weight you
have entered. If the monitor does not provide these values, their fields appear
blank.
‹ For a patient who is not being monitored, confirm the values you have entered.
3. Select the [
Calculate
] button. The system performs a calculation per the current
settings and displays the calculated values.
‹
The values that exceed the range are displayed in yellow background. You can
select [
Range
] to view its normal range in the unit field. For those who are within
the range, their unit fields appear blank.
‹ Invalid values are displayed as [
---
].
In the [
Hemodynamic Calculation
] window, you can:
„ Trigger a recording by selecting the [
Record
] button. The currently displayed renal
calculations are printed out by the recorder.
„ Review the previously performed calculations by selecting [
Review
