Abstract

fetched live from OpenAlex

We measured the effect of altered blood gases induced by breathing high and low oxygen-containing gases in man. The corneoretinal potential was recorded in 15 subjects during isocapnic hypoxia, hypocapnia and hyperoxia. Studies were first conducted in conditions of constant ambient luminance and later during repeated dark and light phases. Isocapnic hypoxia of a degree sufficient to induce arterial oxygen desaturation, reduced the dark trough by a mean ± SD of 49.8 ± 47.6 μV (p < 0.025) with a similar, but less consistent reduction in the light peak (mean = 78.5, SD = 80.8 μV; p < 0.05). By contrast, hyperoxia (PO<sub>2</sub> = 600 mm Hg) and hypocapnia (20–25 mm Hg) under conditions of normal oxygenation had no systematic influence on corneoretinal potential. We conclude that isocapnic hypoxia reduces the capacity of the corneoretinal potential to respond normally to dark and light stimuli but that these responses do not offer a clinically feasible means for noninvasive monitoring of cerebral oxygen delivery.

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.
