Air Embolism Related to Sex in Pregnancy and the Postpartum
Bibliographic record
Abstract
Air embolism is acute embolism resulting from vaginal insufflation. It was first reported in 1936. There is no definite report of its incidence, but has been described in 18 mortalities out of 20 million pregnancies. When air is introduced under pressure, it travels through the dilated cervical canal and beneath the amniotic membranes, to enter the subplacental sinuses. Once air enters the venous drainage of the uterus, it reaches the inferior vena cava, and from there to the right side of the heart. Patients with venous air embolism (VAE) may present with a wide variety of symptoms. The most serious manifestation of VAE is out-of-hospital cardiac arrest. Laboratory abnormalities vary according to the severity of the embolism but lack specificity. The first line of treatment is advising pregnant females against orogenital sex with air insufflation. Accurate diagnosis is the key for managing VAE. Management starts with administration of 100% oxygen, then turning the patient onto her left side in a head-down position. In case of cardiovascular collapse, closed-chest compression is used to remove air trapped in the right side of the heart. Hyperbaric oxygen therapy has been proved to be an effective therapy as well.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
