Checks a bleed after birth against WHO 2025 postpartum hemorrhage criteria.

Example
- Measured blood loss in mL
- 350
- Hours since birth
- 1
- Pulse per minute
- 108
- Systolic pressure, mmHg
- 102
- Diastolic pressure, mmHg
- 66
- Tranexamic acid already given
- No
Result: Meets WHO's 2025 criteria for postpartum hemorrhage (350 mL measured with pulse above 100, shock index above 1): start the first-response bundle now: uterine massage, an oxytocic, tranexamic acid, IV fluids, examine the genital tract, and escalate.
The tool opens with these values already filled in. Replace them with your own.

- Measured blood loss in mL
