answers 402

Diastolic shock index as heart rate in bpm divided by cuff diastolic pressure in mm Hg (Ospina-Tascón 2020). Returns the ratio rounded to two decimals. Not a shock diagnosis, treatment target, or cutoff. Distinct from Allgöwer–Burri HR/SBP shock index. The 2020 cohort had no normal-subject control group, so a DSI cutoff to identify abnormality could be misleading.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
