Acousta - A Doppler for Fetal Monitoring

Balaji Teegala from BRUN Health Pvt. Ltd. in India will develop a Doppler stethoscope - Acousta - that acts both as a standard annular Y-shaped stethoscope and as a Doppler stethoscope. The problem in auscultating the fetal heart to identify birth asphyxia among other fetal morbidities is the difficulty, skill, and training needed while using a regular stethoscope. This is mitigated by active sensing systems like the fetal Doppler systems or cardiotocographs. However, these systems are burdensome to carry in addition to a stethoscope. Alternatively, electronic stethoscopes give clarity during auscultation but are predominantly targeted at specialties like cardiology, while still being passive systems in their approach to sensing physiology. Acousta is a combinatorial approach using both these systems.
