IIIT-H Researchers Develop Mass Monitoring System to Track Multiple Patients’ Vitals

This innovative approach aims to address the challenges associated with mass monitoring scenarios, especially during pandemics.

Researchers from the International Institute of Information Technology, Hyderabad (IIIT-H) have unveiled an advanced algorithm designed to detect the heart rates (HR) and breath rates (BR) of multiple patients simultaneously in a non-invasive manner.

This novel radar-based mass monitoring system has the capability to monitor up to five patients concurrently, presenting a significant advancement in healthcare technology.

Mass Monitoring Contactless Solution

Led by undergraduate researchers Jewel Benny, Pranjal Mahajan, Srayan Chatterjee, and Mohd Wajid, under the guidance of Abhishek Srivastava, the team developed the system based on a frequency-modulated continuous wave (FMCW) mmWave radar.

This innovative approach aims to address the challenges associated with mass monitoring scenarios, especially during pandemics, where conventional methods may fall short.

Explaining the need for non-invasive methods, Benny said, “Normally you have oximeters to check the health of patients with any condition that affects blood oxygen levels such as pneumonia, heart failure, and so on, but they are not really useful in mass monitoring scenarios or during a pandemic-like situation.”

The team aimed to create a single device capable of contactless measurement of vitals for multiple individuals simultaneously, a feat not achieved in previous studies.

Algorithm for Continuous Monitoring

The researchers devised an algorithm to monitor deviations in heart rate and breath rate among patients.

“While the radar is bought from the market, we designed an algorithm to continuously monitor the vitals of patients using chest displacement. Whenever there is any deviation from normal, an alert is sent out,” Benny added.

In addition to simultaneous monitoring, the team emphasized their commitment to improving measurement accuracy through advanced signal processing techniques. By integrating innovative algorithms with radar technology, they aim to enhance the reliability and effectiveness of their monitoring system.

The efforts of the IIIT-H researchers were recognized with the iHub-Anubhuti-IIIT Delhi Foundation’s CHANAKYA Fellowship.

Benny expressed gratitude for the support, emphasizing the importance of further research to refine and enhance the system. The fellowship will provide valuable resources and opportunities to advance their research endeavors.

The development of the radar-based mass monitoring system represents a significant step in healthcare technology. By harnessing the power of radar and innovative algorithms, the IIIT-H researchers seek to pave the way for more efficient and effective monitoring of vital signs in mass settings.

With ongoing research and support from prestigious fellowships, the team is poised to continue refining their system, ultimately contributing to improved patient care and healthcare outcomes.

In another development focusing on patient monitoring, Mylab Discovery-backed healthtech Startup, Sanskritech unveiled Swandook, an ultra-portable anytime health monitoring bag on March 5, 2024. This bag is approved by the Central Drugs Standard Control Organization (CDSCO).

This ultra-portable bag incorporates a telemedicine feature with essential diagnostic tools such as a webcam, dermoscopy, otoscope, and stethoscope. These features enable remote consultations, which are particularly beneficial for follow-up sessions, enhancing convenience for healthcare providers and patients.
