What is the combined TBSA percentage for an adult chest and abdomen?

The combined Total Body Surface Area (TBSA) percentage for an adult chest and abdomen is 18%. This is derived from the "Rule of Nines," a method used in emergency medicine to quickly estimate the percentage of body surface area affected by burns.

In adults, the torso (which includes the chest and abdomen) accounts for 18% of the total body surface area. Specifically, the anterior and posterior aspects of the torso are each assigned 9%, summing up to 18% for the combined total.

Understanding the TBSA is crucial in the management of burn patients, as it helps in assessing the severity of the burns and guiding treatment decisions effectively. This knowledge is important for Primary Care Paramedics in order to provide appropriate and timely care to those affected by burn injuries.
