AeroSpectra Sentinel: An Auditable LLM Prompt-Chaining Decision-Support Workflow for Acute Asthma Risk Assessment from Respiratory Sounds and Clinical Signals
TL;DR
Acute asthma risk assessment requires quick analysis of various clinical signals, but existing audio classifiers often lack transparency in their decision-making. AeroSpectra Sentinel is a decision-support workflow that utilizes short-time Fourier transform (STFT) to analyze respiratory sounds alongside clinical data.
✦ Why It Matters
Engineers can apply STFT and decision-support workflows to enhance clinical assessments in respiratory health.
Key Takeaways
- Explore STFT for analyzing respiratory sounds in clinical settings.
- Implement decision-support workflows to improve patient care.
- Focus on transparency in AI decision-making for healthcare applications.
- Evaluate the integration of audio analysis with clinical signals.
Full Summary
Acute asthma poses significant risks that necessitate rapid and accurate assessment of multiple clinical signals, including respiratory sounds and oxygenation levels. Traditional audio classifiers primarily focus on detecting wheeze-like patterns but often fail to provide clear reasoning for their decisions, which can compromise patient safety.
AeroSpectra Sentinel was developed as a client-side research prototype that integrates short-time Fourier transform (STFT) analysis of respiratory sounds with other clinical indicators. This decision-support workflow not only improves the interpretability of the assessments but also incorporates safe escalation logic for clinical responses.
Initial evaluations indicate that this system can enhance the accuracy of asthma risk assessments, potentially leading to better patient outcomes. The implications of this work suggest that engineers and researchers can leverage advanced audio analysis techniques to improve clinical decision-making processes.
