Blood Component Calculators

Estimate generic adult and paediatric dosing requirements aligned with standard BSH guidelines.

Patient Weight (kg)

Current Hb (g/L)

Target Hb (g/L)

Component Advice

Adult

Red Cells	1 unit(s) (~10g/L increment per unit)
Platelets	1 ATD (Adult Therapeutic Dose) (~20–40 ×10⁹/L increment)
FFP	1050 mL (15 mL/kg standard dose)
Cryoprecipitate	2 Pools (10 individual units) (Standard adult dose)

Massive Haemorrhage Protocol (MHP):

For major bleeding, administer blood components dynamically based on point-of-care or laboratory coagulation results. Do not wait for calculation; follow local MHP activation procedures (typically empirical ratios initially, e.g., 1:1 RBC:FFP).
