Formula Used

Estimate HFNC oxygen duration from oxygen source, FiO2, and flow. Selecting LOX switches the supply input to liters of liquid oxygen.

Formula Used

Estimate ventilator oxygen duration from patient size, exhaled minute ventilation, oxygen source, and FiO2. Selecting LOX switches the supply input to liters of liquid oxygen.

Formula Used

Estimate 24-hour lactated Ringer's requirement for an adult burn patient. Count only partial-thickness (2nd degree) and full-thickness (3rd degree) burns toward %TBSA.

Burn Map (adult)

Paint the burned areas with your finger or mouse. %TBSA is calculated from the painted surface, weighted by Rule of Nines body regions.

Painted: 0% TBSA

Formula Used

Painted TBSA is an estimate weighted by Rule of Nines regions. Fluid totals are a starting point — titrate to urine output and hemodynamics per protocol and medical direction.

Estimate 24-hour lactated Ringer's requirement for a pediatric burn patient, plus dextrose-containing maintenance fluids. Count only partial-thickness (2nd degree) and full-thickness (3rd degree) burns toward %TBSA.

Burn Map (pediatric)

Paint the burned areas with your finger or mouse. %TBSA is calculated from the painted surface, weighted by Rule of Nines body regions.

Painted: 0% TBSA

Formula Used

Painted TBSA is an estimate weighted by Rule of Nines regions. Resuscitation fluid is in addition to maintenance. Titrate to urine output (1 mL/kg/hr in children) and hemodynamics per protocol and medical direction.
