From scene to ED — fast, accurate, defensible

Firefighters in the U.S. respond to far more medical calls than fires — most departments report 70–80% of total runs are EMS. These tools support the medical side of the job: a burn calculator that produces an EMS-to-ED handoff card in seconds, and a locator for nearest hospital or transport agency when local knowledge runs out.

Burn TBSA + Parkland

Tap each affected body region on the diagram, choose depth (1°, 2°, 3°), and the calculator computes Total Body Surface Area using the Rule of Nines for adults or the Lund-Browder pediatric chart. Patient weight (kg or lb) feeds the Parkland formula: 4 mL × kg × %TBSA for total Lactated Ringer's in 24 hours, with first 8 hours / next 16 hours drip rates. Burn-center referral threshold is auto-flagged.

FAQ

Total Body Surface Area — the percentage of a patient's body affected by partial-thickness (2°) and full-thickness (3°) burns. Superficial 1° burns (sunburn) are not counted toward TBSA. The number drives fluid resuscitation, transfer to a burn center, and prognosis.

Use Rule of Nines for any patient 15 years or older. Use Lund-Browder for pediatric patients (under 15). Children's heads are proportionally larger and legs proportionally smaller than adults — Lund-Browder adjusts the regional percentages by age bracket (under 1, 1–4, 5–9, 10–14).

4 mL × patient weight (kg) × %TBSA = total Lactated Ringer's volume for the first 24 hours from time of injury. Half is given over the first 8 hours, the remaining half over the next 16 hours. Intended for partial- and full-thickness burns covering ≥20% TBSA in adults or ≥10% in children.
