What DASI Calculator (Duke Activity Status Index) does
The DASI Calculator estimates a patient’s functional capacity using the Duke Activity Status Index questionnaire. It converts activity-level responses into an estimate of peak oxygen uptake (VO₂ peak), a key metric for evaluating cardiovascular health. Users complete a 12-item self-administered survey covering daily activities such as walking, climbing stairs, and recreational sports; the tool then outputs a DASI score, MET values, and an estimated VO₂ peak. The site includes a brief explanation of the index’s clinical purpose and a disclaimer that results cannot replace professional medical advice.

DASI Calculator (Duke Activity Status Index) FAQ
- What does the DASI score measure and how is it used?
- The DASI score estimates peak oxygen uptake (VO₂ peak) from a 12-item self-administered questionnaire. Clinicians mainly use it to evaluate patients with cardiovascular diseases, measure functional capacity, assess quality of life, and monitor the effect of medical treatments or cardiac rehabilitation.
- Can the DASI Calculator replace a medical exam or stress test?
- No, the tool provides an estimate based on self-reported activity levels and includes a disclaimer that it cannot replace professional medical advice or diagnostic testing.
- What activities are included in the DASI questionnaire?
- The 12-item questionnaire covers daily activities such as walking indoors, walking 1–2 blocks, climbing hills or stairs, running, performing light to heavy housework, yardwork, sexual relations, and recreational or strenuous sports.
- Who developed the Duke Activity Status Index and when?
- Hlatky and colleagues developed the Duke Activity Status Index in 1989.
