A new computerized system minimizes errors in cardiopulmonary bypass by automatically recording vital data. It also corrects hematocrit values using an innovative formula, improving data accuracy during surgery.

Area of Science:

  • Cardiovascular Surgery
  • Biomedical Engineering
  • Medical Instrumentation

Context:

  • Cardiopulmonary bypass procedures are susceptible to human error.
  • Accurate monitoring of physiological parameters is critical during bypass.
  • Existing systems may not capture all necessary data or account for interferences.

Purpose:

  • To develop a computerized recording system to reduce perfusionist errors.
  • To integrate data from the GEM 6 PLUS analyzer for comprehensive monitoring.
  • To improve the accuracy of hematocrit measurements during cardiopulmonary bypass.

Summary:

  • A novel computerized system was created to log perfusion flow, pressure, urine output, and temperature.
  • The system automatically records data from the GEM 6 PLUS analyzer (pH, PCO2, PO2, BE, Ca2+, K+, hematocrit).

  • A new formula (HCT = GEMHCT + 0.28 x ([Na+]+[K+]) -44) corrects hematocrit based on electrolyte concentrations, addressing potential errors.

    • Impact:

    • Reduced artificial errors in cardiopulmonary bypass procedures.
    • Enhanced accuracy of critical physiological measurements, particularly hematocrit.
    • Potential for improved patient outcomes through more reliable data monitoring.
