Clinical Significance
The 6MWT is the global gold standard for predicting mortality and hospitalization in chronic cardiopulmonary conditions. It provides a real-world assessment of functional mobility that treadmill tests cannot replicate.
Official ATS Testing Protocol
- 1. Preparation: Patient should rest for 10 minutes prior to the test. Measure baseline HR and SpO2.
- 2. Setup: A 30-meter (100 ft) flat hallway marked every 3 meters.
- 3. Execution: Use standardized phrases: "You are doing well. You have 3 minutes left."
- 4. Termination: Stop if the patient experiences chest pain, intolerable dyspnea, or leg cramps.
Frequently Asked Questions
What does a score below LLN indicate?
A score below the Lower Limit of Normal (LLN) indicates severe functional impairment and is a strong predictor of poor clinical outcomes in COPD and Heart Failure.
How is the Predicted Distance calculated?
Our tool utilizes the Enright & Sherrill equations, which account for the natural physiological decline associated with age and height-based stride length.
