Abstract

fetched live from OpenAlex

Abstract Aim To examine potential correlations between cardiac output (CO) with cerebral‐regional‐oxygen‐saturation (crSO 2 ) and cerebral‐fractional‐tissue‐oxygen‐extraction (cFTOE) during immediate foetal‐to‐neonatal transition in term and preterm neonates with and without respiratory support. Methods Post hoc analyses of secondary outcome parameters of prospective observational studies were performed. We included neonates with cerebral near‐infrared‐spectroscopy (NIRS) monitoring and an oscillometric blood pressure measurement at minute 15 after birth. Heart rate (HR) and arterial oxygen saturation (SpO 2 ) were monitored. CO was calculated with Liljestrand and Zander formula and correlated with crSO 2 and cFTOE. Results Seventy‐nine preterm neonates and 207 term neonates with NIRS measurements and calculated CO were included. In 59 preterm neonates (mean gestational age (GA): 29.4 ± 3.7 weeks) with respiratory support, CO correlated significantly positively with crSO 2 and significantly negatively with cFTOE. In 20 preterm neonates (GA 34.9 ± 1.3 weeks) without respiratory support and in 207 term neonates with and without respiratory support, CO correlated neither with crSO 2 nor with cFTOE. Conclusion In compromised preterm neonates with lower gestational age and in need of respiratory support, CO was associated with crSO 2 and cFTOE, whereas in stable preterm neonates with higher gestational age as well as in term neonates with and without respiratory support, no associations were observed.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
