What is the calculated fluid resuscitation volume for Don Johnson based on the Parkland formula?

The Parkland formula is commonly used to estimate the fluid resuscitation volume required for burn victims during the first 24 hours post-injury. The formula is expressed as:

Total fluid requirement (in mL) = 4 mL × body weight (in kg) × percentage of total body surface area (TBSA) burned.

For the calculation to yield 7200 mL, it is necessary to know both the patient's weight and the estimated percentage of burns. If, for example, Don Johnson weighs 90 kg and has 80% of his TBSA burnt, you would calculate as follows:

Total fluid requirement = 4 mL × 90 kg × 80 = 28800 mL over 24 hours. Since the first 50% should be administered in the first 8 hours, if he had a less severe burn, such as 30% TBSA burned, the volume would be calculated using:

Total fluid requirement = 4 mL × 90 kg × 30 = 10800 mL over 24 hours; given the rapid administration in the first 8 hours, this means 7200 mL should be given for the first 12 hours.

This calculation reflects the significance of the
