    Area of Science:

    • Physiology
    • Medical Engineering
    • Critical Care Medicine

    Background:

    • Predicting acute physiological responses to stress is crucial in clinical settings.
    • Cardiopulmonary bypass (CPB) presents unique metabolic and respiratory challenges.
    • Previous methods for predicting stress response were limited to animal models.

    Purpose of the Study:

    • To extend a validated animal model method for predicting acute stress response to human patients.
    • To assess the accuracy of a single nomogram for predicting responses to metabolic and respiratory stress during CPB.
    • To evaluate the nomogram's utility in estimating therapeutic bicarbonate requirements.

    Main Methods:

    • Extension of an established experimental animal method to human subjects.

    Related Experiment Videos

  • Development and application of a single nomogram for stress response prediction.
  • Validation using data from 13 patients undergoing CPB.
  • Comparison with independently reported patient data.

    • Main Results:

    • The nomogram accurately predicts acute responses to metabolic stress (bicarbonate administration) in humans.
    • The nomogram accurately predicts acute responses to respiratory stress (oxygenator gas manipulation) during CPB.
    • The nomogram demonstrated similar agreement with patient data as previously observed in animal studies.
    • The nomogram's predictions showed good correlation with clinical outcomes.

    Conclusions:

    • A single nomogram effectively predicts human responses to metabolic and respiratory stress during CPB.
    • This method provides a reliable tool for clinical decision-making in CPB patients.
    • The nomogram facilitates accurate estimation of bicarbonate dosage, optimizing patient management.
