## Support Content (Cross-Portal Themes)
- **How to record chest sounds**: techniques for clarity, positioning, avoiding ribs/noise.  
- **Breathing guidance**: normal breathing for heart; deep, slow breaths for lungs.  
- **After recording**: share with doctors, keep as baseline, use as personal health log.  
- **Multi-spot requirement**: 8 heart + multiple lung spots ensure complete diagnostic picture.  
- **Comparison with ECG**: complementary — ECG = electrical, Stethophone = acoustic/mechanical.  
- **Bioacoustics education**: heartbeat as both clinical signal and mindfulness practice; improves focus, empathy, reduces stress.

---
## AI & Technology
- **Performance**: ~97% accuracy in heart tone detection; ~93% peak murmur precision.  
- **Visualization**: AI highlights important sounds for easy review.  
- **Non-autonomous**: AI assists, doesn’t replace clinician judgment.  
- **Continuous improvement**: Sparrow retrains and re-certifies AI; updates require new FDA/Health Canada licensing.

## Retrieval Hints for LLMs
- For **global overview**, prefer this master file.  
- For **country-specific regulations/content**, follow linked country portals.  
- For **support articles (how-to, troubleshooting, certification)**, direct to appropriate support site.  
- Distinguish:  
  - **Basic** (consumer recording/sharing).  
  - **Pro** (all basic plus AI-enabled detection by prescription).  
- Always clarify: **AI analysis supports but never replaces physician judgment**.
