Know more about our Medical Review Policy (Dr. Rishav Das)

Scope of Medical Review Authority

Dr. Das translates clinical validation research on consumer wellness devices into consumer-friendly analysis. His role encompasses:

Testing methodology review: Develops evidence-based testing protocols for each device category
Dataset integrity verification: Evaluates sensor accuracy, measurement reliability, and clinical relevance
Claim alignment: Reviews device claims against clinical guidelines and peer-reviewed research
Safety assessment: Identifies potential risks, contraindications, and appropriate use cases
Content medical review: Ensures all health claims and metrics explanations are medically sound

Explicit Scope Boundaries

Transparency is the foundation of trust. Every device we review follows a rigorous, evidence-based evaluation process that combines technical testing with medical expertise. Here’s exactly how we work:

Dr. Das is qualified to:

• Translate clinical research into plain language
• Understand physiological systems and measurement science
• Test consumer device accuracy methodically
• Read and interpret peer-reviewed validation studies

Dr. Das does NOT provide:

• Medical diagnosis or disease interpretation
• Clinical treatment recommendations
• Medical device regulation or FDA classification determinations
• Clinical decision-making in any medical specialty
• Substitution for healthcare provider evaluation

Final editorial and medical authority: All published content undergoes medical review by Dr. Das before publication. This review focuses on device measurement accuracy, clinical validity translation, and safety disclosures—not medical diagnosis or treatment.

Editorial Governance

This page serves as the single canonical authority for all E-E-A-T claims across the Wearable Wellness Guide.

Medical Governance & Safety Policy

Scope of Medical Content

FDA General Wellness Classification

Content on this site analyzes consumer wellness devices that fall under FDA’s general wellness exemption. These devices:

• Do not claim to diagnose, treat, cure, or prevent disease
• Are not subject to FDA premarket approval
• Are intended for general fitness, wellness, or health maintenance

When devices have FDA clearance (510(k) or De Novo), this is explicitly noted with regulatory documentation linked.

Safety Disclosures & Emergency Guidance

Every page includes safety callouts with:

• Specific numeric thresholds requiring emergency care
• Symptom checklists for urgent medical attention
• Clear distinction between device data and clinical diagnosis
• Explicit instructions to seek physician evaluation when needed

Standard safety callout template:

⚠️ QUICK SAFETY REFERENCE

EMERGENCY (Call 911):

• Heart rate >180 bpm or <40 bpm (awake)
• Blood pressure >180/120 mmHg
• SpO₂ ≤85% at rest
• Chest pain, severe shortness of breath, fainting

NON-EMERGENCY (See physician):

• Irregular rhythms, BP >140/90 consistently
• SpO₂ <90% during sleep
• Unexplained resting HR change >20 bpm

Consumer devices detect patterns—NOT diagnose. Physician review required.
