Beyond SpO₂: Unlocking Respiratory Intelligence from Fingertip Wearables
Speaker: Hau-Tieng Wu (United States)
Sponsored sessions are not eligible for CE credit.
Session Overview
▼
For years, fingertip photoplethysmography (PPG) has been clinically restricted to monitoring heart rate and oxygen saturation (SpO₂). However, buried within these optical signals and accompanying inertial sensors is a wealth of underutilized physiological data.
This session bridges the gap between signal processing and clinical physiology to reveal how we can reliably extract respiratory information from the fingertip. Through a gentle introduction to mathematical models capturing the physiological dynamics behind respiration-induced PPG variations, attendees will learn to utilize respiratory dynamics from three distinct aspects:
By unlocking these hidden waveforms through advanced digital signal processing (DSP), we can transform a standard wearable into a comprehensive respiratory monitoring tool.
