EpistemisBedside Hemodynamics: Mean Blood Pressure, Pulse Pressure and Shock Index
Four derivatives from taking constants that no monitor shows together. Proportional pulse pressure below 25% indicates low cardiac index in decompensated heart failure; shock index above 0.9 anticipates collapse before systolic falls.
Required inputs
| Variable | Example value |
|---|---|
| Systolic blood pressure (mmHg) | 120 |
| Diastolic blood pressure (mmHg) | 75 |
| Heart rate (bpm) | 80 |

This page explains the score but does not run it. In Epistemis, the calculator validates units, flags values outside physiological ranges, and provides the interpretation that a number alone cannot convey.
Epistemis is educational review material. It is not a medical device, does not diagnose or prescribe treatment, and does not replace formal medical training, current clinical guidelines, or professional clinical judgment.
