Abstract

User interfaces for medical perfusion systems that provide oxygenation, filleting, and recirculation of blood in connection with various medical procedures are provided. In particular, methods of displaying and communicating a desired target flow rate and cardiac index during cardiopulmonary bypass surgeries are provided.

Claims

1. A user interface for graphically providing a target blood flow rate during cardiopulmonary bypass surgery, the user interface comprising:

a display screen;

a first graphical indicator of actual real time blood flow rate displayed on the display screen;

a second graphical indicator of target blood flow rate displayed on the display screen, wherein the target blood flow rate is based on a desired cardiac index; and

a numerical value of actual real time cardiac index displayed on the display screen.

2. The user interface of claim 1, further comprising a numerical value of actual real time blood flow displayed on the display screen.

3. The user interface of claim 1, wherein the first graphical indicator of actual real time blood flow rate comprises a horizontal bar, the length of which indicates blood flow rate.

4. The user interface of claim 3, wherein the second graphical indicator of target blood flow rate comprises a vertical bar overlayed on the first graphical indicator.

5. The user interface of claim 4, wherein the second graphical indicator comprise green.

6. The user interface of claim 1, further comprising a settings screen having at least one adjustable patient data parameter.

7. The user interface of claim 1, in combination with a cardiopulmonary bypass perfusion system.
