Logistic regression models reveal arterial pH influences outcomes in out-of-hospital cardiac arrest, suggesting its clinical relevance.

Inclusion of arterial pH in models improved prediction for 30-day mortality or unfavorable neurological status.
92.2% of patients analyzed faced death or unfavorable neurological outcomes, showcasing the study's impact on patient care.
Models with arterial pH achieved AUROC scores of 0.93-0.95, indicating strong predictive performance compared to low-flow time models.
The use of pH in prediction models could enhance clinical outcomes in patients experiencing cardiac arrest.

Jeong et al. (2025) studied this question.
