monitoring a perfusion control system during cardiopulmonary bypass surgery by way of a user interface of the perfusion control system comprising a display screen, the display screen showing a color coded system status bar that includes distinct bar portions, with one bar portion for displaying a first color, a second bar portion for displaying a second color, and a third bar portion for displaying a third color;

displaying the first color within the first portion of the color coded system status bar during normal operation of the perfusion system;

receiving information indicative an occurrence of a first system operational problem and a second system operational problem;

prioritizing the first and second system operational problems such that one of the first and second operational problems is designated as a highest priority system operational problem and the other of the first and second operational problems is designated as a next highest priority system operational problem;

displaying one of the second or third color within the respective second or third bar portion based upon the highest priority system operational problem, the color being displayed indicating any one out of a plurality of system conditions as have been prioritized according to a level of the system operation problem as such system operational problems have been programmed into the perfusion control system;

displaying a first message indicative of the highest priority system operational problem within a distinct system message box that is positioned separately from the status bar on the display screen, thereby indicating a specific system operation problem out of the plurality of system conditions that have been prioritized according to the level represented by the displayed color; and

subsequently displaying a second message indicative of the next highest priority system operational problem within the distinct system message box upon correction of the highest priority system operational problem.

2. The method of claim 1, wherein the first, second, and third colors comprise green, yellow, and red, respectively.

3. The method of claim 2, wherein red indicates an alarm condition requiring immediate corrective action.

4. The method of claim 2, wherein yellow indicates an alert condition requiring non-immediate corrective action.

5. The method of claim 2, wherein green indicates absence of a requirement for corrective action.

6. The method of claim 1, further comprising a step of displaying a color coded system management icon on the display screen for managing the displayed system operational problem.

7. The method of claim 1, further comprising the step of displaying real time operating data indicators on the display screen.

8. A perfusion control system and a user interface for managing a condition change of a perfusion system during cardiopulmonary bypass surgery, the user interface comprising:

a display screen including a color coded system status bar that includes distinct bar portions, with one bar portion for displaying a first color, a second bar portion for displaying a second color, and a third bar portion for displaying a third color;

the display screen further including a coded textual message portion that is positioned separately from the status bar on the display screen for providing information related to a system operational problem, wherein each of the first, second, and third colors of the status bar indicate a distinct system condition; and

the perfusion control system being programmed with system operational problems according to plural levels of severity with plural system operational problems prioritized as of an alert level and associated with the second color of the second bar portion and with plural operation problems prioritized as of an alarm level and associated with the third color of the third bar portion, the perfusion control system operatively connected with the display screen of the user interface so that under normal operation conditions the first color is displayed in the first bar portion, under the alert level of system operational problems the second color is displayed in the second bar portion and the coded textual message portion includes information of a specific operational problem of the alert level, and under the alarm level of system operational problems the third color is displayed in the third bar portion and the coded textual message portion includes information of a specific operational problem of the alarm level, wherein the perfusion control system is further programmed such that upon occurrence of a plurality of system operational problems, the display screen is prompted message in the coded textual message portion relating to a highest priority operational problem, followed by the display screen being prompted to display a second message in the coded textual message portion relating to a next highest priority operational problem upon correction of the highest priority operational problem.

9. The user interface of claim 8, wherein the display further comprises one or more color coded system management icons that are displayed positioned separately from the status bar and separately from the coded textual message portion on the display screen for managing a specific operational problem based on the color coded system status bar under an alert or alarm condition.

10. The user interface of claim 8, further comprising real time operating data indicators displayed on the display screen.

11. A pump console for use during cardiopulmonary bypass surgery, the pump console comprising a base unit and the perfusion control system with the user interface of claim 8, the base unit comprising one or more interfaces for controlling pump speed, monitoring flow, and communicating with the user interface.

12. The pump console of claim 11, further comprising one or more of an automated arterial line occlusion system, level detectors operatively connected to a blood reservoir, and a bubble detector system.

13. A method of managing a condition change of a perfusion system during cardiopulmonary bypass surgery, the method comprising the steps of:

monitoring a perfusion control system during cardiopulmonary bypass surgery by way of a user interface of the perfusion control system comprising a display screen, the display screen showing a color coded system status bar that includes distinct bar portions, with one bar portion for displaying a first color, a second bar portion for displaying a second color, and a third bar portion for displaying a third color;

displaying the first color within the first portion of the color coded system status bar during normal operation of the perfusion system, and subsequently displaying one of the second or third color within the respective second or third bar portion upon an occurrence of a system operational problem, the color being displayed indicating any one out of a plurality of system conditions as have been prioritized according to a level of the system operation problem as such system operational problems have been programmed into the perfusion control system;

displaying a message within a distinct system message box that is positioned separately from the status bar on the display screen and thereby indicating a specific system operation problem out of the plurality of system conditions that have been prioritized according to the level represented by the displayed color; and

displaying a color coded system management icon that is positioned separately from the status bar and separately from the system message box on the display screen for managing the displayed system operational problem based on the color coded system status bar under an alert or alarm condition.

14. The method of claim 13, wherein the first, second, and third colors comprise green, yellow, and red, respectively.

15. The method of claim 14, wherein red indicates an alarm condition requiring immediate corrective action.

16. The method of claim 14, wherein yellow indicates an alarm condition requiring non-immediate corrective action.
