Submission of RFI (Request for Information) to JAXA Space Exploration Innovation Hub

On May 9, 2025, in response to a Request for Information (RFI) issued by JAXA as part of its regular solicitation for university and corporate technologies useful for space exploration, Professor Keitaro Senoo of the Department of Cardiovascular Medicine, Arrhythmia Advanced Medical Science, Kyoto Prefectural University of Medicine, and others submitted a joint proposal titled “Technology for Predicting Patient Severity and Performing Emergency Triage in Space Using a Machine Learning Model Based on Vital Data Obtainable from Wearable Devices.”

This concept aims to develop a machine learning model that can predict death or severe deterioration based solely on vital signs (blood pressure, heart rate, respiratory rate, oxygen saturation, and body temperature) obtained from wearable devices, and perform emergency triage in medical emergencies involving lunar surface dwellers.

In environments with limited medical resources, such as the moon or outer space, the goal is to enable triage decisions, including the urgent return of critically ill patients. We also believe this technology could be applied to disaster medical sites on Earth, medically underserved areas, and emergency calls for elderly patients with unknown medical histories, to help determine appropriate transportation destinations.

The RFI includes fairly specific technical requirements in the field of ●Habitation Healthcare Science.

As a critical field in human space exploration, we will actively propose the utilization of outstanding technologies from universities and companies.
