Area of Science:

  • Biomedical Engineering
  • Cardiovascular Surgery
  • Respiratory Physiology

Background:

  • Continuous advancements in oxygenator technology are crucial for enhancing patient safety and support during cardiopulmonary bypass (CPB).
  • Evaluating new oxygenator models is essential to ensure optimal gas exchange and patient outcomes.

Purpose of the Study:

  • To compare the performance of the Maxima 1380 oxygenator with its upgraded counterpart, the Maxima Plus oxygenator.
  • To assess the efficiency of gas transport (oxygen and carbon dioxide) between the two oxygenator models.

Main Methods:

  • A randomized study involving 32 adult patients undergoing CPB.
  • Data collection included patient demographics, physiological parameters (temperature, saturation, blood gases), blood flow, and oxygenator settings (gas sweep, FiO2).

  • Statistical analysis was performed to compare the two groups and identify correlations between variables.

    • Main Results:

    • No significant differences were observed between the Maxima 1380 and Maxima Plus groups in terms of patient weight, body surface area, arterial blood gases, temperature, venous oxygen saturation, or blood flow.
    • The Maxima Plus group exhibited significantly lower mean gas sweep rates and fraction of inspired oxygen (FiO2) settings.
    • The Maxima 1380's FiO2 and gas sweep rate were dependent on multiple patient and procedural variables, whereas the Maxima Plus showed simpler dependencies.

    Conclusions:

    • The Maxima Plus oxygenator demonstrates superior efficiency in oxygen and carbon dioxide transport compared to the Maxima 1380.
    • The improved efficiency of the Maxima Plus may lead to optimized gas exchange during cardiopulmonary bypass.
    • These findings suggest the Maxima Plus represents a significant advancement in oxygenator technology for CPB.
