Abstract

A cardiopulmonary bypass or CPB monitoring tool includes: a preoperative information module; a preoperative calculation module able to estimate a body surface area, blood volume, and theoretical weight; a priming module able to determine priming constitution, volume and flow to achieve a hemodilution target; an operation risk module for calculating operation risk; a drug calculation module able to determine medication doses; a timer module with timers that can be activated during operation; a data collection module with an interface and drivers enabling data collection from a wide variety of extracorporeal pumps and oxygenators during operation; an events module with retroactive manipulation of the time of an event; a printing report generation module; a graphic user interface; and a configuration module.

Claims

1. A cardiopulmonary bypass or CPB monitoring tool (100) comprising:

a preoperative information module configured to enable entry and management of patient data, pathology data, medication data, operation team data, material data for use during operation;

a preoperative calculation module configured to enable estimation of a body surface area or BSA, blood volume, and theoretical weight from said patient data;

a priming module configured to enable determination of priming constitution, volume and flow to achieve a hemodilution target;

an operation risk module configured to calculate operation risk according to Euroscore and/or Parsonnet formulae;

a drug calculation module configured to determine medication doses that must be administered during operation;

a timer module comprising one or more timers that can be activated during operation;

a data collection module comprising an interface and drivers configured to enable data collection from a wide variety of extracorporeal pumps and oxygenators during operation;

an events module configured to enable entry and management of events during operation, and to enable retroactive manipulation of the time of an event;

a printing report generation module providing user-configurable parameter selection for at least one report;

a graphic user interface; and

a configuration module said graphic user interface, said configuration module configured to enable selection of fields for entry of preoperative information, labelling of said fields selected and positioning of said fields selected in data entry screens used by said preoperative information module for entry of preoperative information, enabling configuration of standard priming constitutions, enabling initialisation of medical team members, enabling initialisation of materials, enabling configuration of interfaces to extracorporeal pumps, and to enable configuration of chart screens displayed during operation in said graphical user interface.

2. A CPB monitoring tool according to claim 1, wherein said priming module is further configured to determine valve diameters and/or cannula sizes for paediatric CPB.

3. A CPB monitoring tool according to claim 1, wherein said timer module comprises:

a first timer (BYPASS) that registers bypass time;

a second timer (AORTA CLAMP) that registers aorta clamp time;

a third timer (ACT) that registers time lapsed since a last Anti Coagulation Time or ACT measurement; and

a fourth timer (CPG) that registers time lapsed since a last CPG dose.

4. A CPB monitoring tool according to claim 1, wherein said timer module comprises one or more user-configurable timers (USER DEFINED).

5. A CPB monitoring tool according to claim 1, wherein said events module is configured to store a list of standard events that take place before, during and after a PCB.

6. A CPB monitoring tool according to claim 1, further comprising:

a medication module configured to log medication supplied during operation.

7. A CPB monitoring tool according to claim 1, further comprising:

a theoretical and measured haematocrit evolution graph generator configured to enable the evolution of the patients hemodilution throughout an operation procedure.

8. A CPB monitoring tool according to claim 1, further comprising:

a heparin dose response curve generator configured to derive a patients response of a patient to a first heparin dose and to predict additional heparin doses in order to achieve a target ACT value and to predict at the end of an operation procedure how much heparin is leftover to be neutralized in order to restore normal coagulation.

9. A CPB monitoring tool according to claim 1, further comprising:

a draw module configured to enable drawing a coronary bypass and sequential anastomosis.

10. A CPB monitoring tool according to claim 1, wherein said material module is configured to enable evidence based material selection.

11. A CPB monitoring tool according to claim 1, further comprising:

a statistical module configured to perform statistic calculations on a population of patients.

12. A CPB monitoring tool according to claim 1, further comprising:

connectivity to an application that enables remote monitoring during extracorporeal membrane oxygenation or ECMO.

13. A CPB monitoring tool according to claim 9, further comprising:

a module configured to generate an alarm via e-mail or SMS.

14. A CPB monitoring tool according to claim 1, configured to visualize during operation derived calculated parameters to assist a perfusionist.
