  1. What two signals does a cardiotocograph (CTG) record?
    • Maternal blood pressure and oxygen levels
    • Fetal heart rate and uterine contractions
    • Fetal brain activity and movement
    • Placental blood flow and glucose
  2. What did the UK INFANT trial of CTG decision-support software find?
    • It halved emergency caesarean sections
    • It replaced midwives on labor wards
    • No improvement in poor neonatal outcomes compared with usual care
    • It was stopped because it was too accurate
  3. What are the Dawes-Redman criteria?
    • Rule-based computerized criteria for analyzing antenatal CTGs
    • A deep learning model for ultrasound
    • A blood test for preeclampsia
    • A labor positioning guideline
  4. What can blind-sweep AI do for clinics without trained sonographers?
    • Perform caesarean sections remotely
    • Diagnose preeclampsia from video
    • Replace CTG monitoring in labor
    • Estimate gestational age and fetal position from simple probe sweeps by untrained staff
  5. Which inputs does the Fetal Medicine Foundation preeclampsia model combine?
    • Only maternal age and weight
    • Maternal factors, mean arterial pressure, uterine artery pulsatility index and placental growth factor
    • CTG traces from labor
    • Genetic sequencing of the fetus
  6. What did the ASPRE trial show?
    • Screening with the model and giving aspirin to high-risk women substantially reduced preterm preeclampsia
    • AI CTG reduced stillbirth
    • Ultrasound AI had no errors
    • Aspirin was harmful in pregnancy
  7. Why do CTG models learn partly from clinician behavior rather than pure physiology?
    • Clinicians label every trace by hand for each model
    • Models read clinicians' notes instead of traces
    • Clinicians often intervened when traces looked worrying, changing what outcome would have occurred
    • CTG machines are controlled by clinicians
  8. Which signal problem must a CTG model handle before extracting features?
    • Too many ultrasound frames
    • Nadmierna rozdzielczość obrazu
    • Missing contraction timestamps only
    • Signal loss and mistaking the maternal heart rate for the fetal one
