Science

Proven in trauma care. Now built for birth.

Compensatory reserve is established in trauma medicine. We are bringing it to obstetrics, and testing it on our own data.

0.90

AUC predicting collapse in trauma medicine, against 0.56 for the perfusion index.

Janak et al., 20155

51

women at caesarean. Those who bled had lower reserve. Blood pressure could not tell them apart.

Reppucci et al., 20246

0.815

AUC for our own model, from pulse shape alone, across 1,570 patients.

Public ICU data with a proxy label. Not yet a maternal model.

Works alongside the calibrated drape, and learns from it. The WHO-recommended drape measures blood already lost. In our pilots, that measurement trains the maternal model.

Progress

Where we are.

  1. Done

    • Aya Mama app on Google Play, 50+ interviews with mothers and providers
    • Hardware specification locked
    • Waveform pipeline within 0.8 bpm of ECG on PhysioNet data

  2. Now

    • Opening in Kigali, Rwanda
    • Rwanda pilot pathway
    • Hardware build partner in Kenya

  3. Next

    • Working prototype and ward platform
    • Safety testing, ethics and Rwanda FDA approvals
    • First pilot: 100+ mothers across 5 to 10 facilities
