Key result
Among 5,000 clinical perfusions, the mean safety index for 10 oxygenator brands was 1.6 (ranging from 0 to 2.92), indicating that oxygenator safety margins vary between different brands.
Why the study?
Do safety margins and incident rates vary between different oxygenator brands used in cardiopulmonary bypass?

5000 clinical perfusions undergoing cardiopulmonary bypass over a seven-year period
Comparison
10 different oxygenator brands vs Reference safety index (SI) of 0.2
Design
Cohort
Follow-up
7 years (data collection period)

Observed oxygenator safety margin variation across brands is hypothesis-generating; prospective trials needed before guiding selection.

Do safety margins and incident rates vary between different oxygenator brands used in cardiopulmonary bypass?
Absolute Event Rate: 1.6% vs 0.2%
Systematic analysis of adverse events during cardiopulmonary bypass demonstrates that safety margins vary significantly between different oxygenator brands.
Svenmarker et al. (1997) conducted an observational in Cardiopulmonary bypass (n=5,000). 10 different oxygenator brands vs. Reference safety index of 0.2 was evaluated on General safety index (SI) defined as recorded incidents per total number multiplied by 100. Among 5,000 clinical perfusions, the mean safety index for 10 oxygenator brands was 1.6 (ranging from 0 to 2.92), indicating that oxygenator safety margins vary between different brands.
