Dasi is a fast, free health calculator. Enter Number of Yes Responses (0-12) and Activity Intensity to get an instant, accurate result — complete with the formula, a step-by-step worked example, and answers to common questions, all on one page and private to your browser.

Formula

DASI = Responses × 1.54; METs = 0.43 × DASI + 9.6
  • DASI = Duke Activity Status Index
  • METs = Metabolic Equivalents
  • Used in cardiac risk assessment

Cardiac Capacity

Inputs
  • Number of Yes Responses (0-12): 9 count
  • Activity Intensity: moderate

9 yes responses = DASI 13.86, METs 15.6, indicating good functional cardiac capacity.

Frequently asked questions

What does DASI measure?
Functional cardiac capacity based on patient's ability to perform daily activities.
What are METs?
Metabolic Equivalents represent exercise intensity; 1 MET = rest, 5+ METs = moderate exercise.
