A NACA score (or National Advisory Committee for Aeronautics score) is a scoring system of the severity in cases of medical emergencies such as injuries, diseases or poisonings. It was developed from the National Advisory Committee for Aeronautics for accidents in aviation.^[1]^[2]

The NACA score is divided into the following, specified with Roman numerals or the Arabic zero.^[2]

Categories:

Category	Description	Example
NACA 0	No injury or disease. This category is often deleted or replaced by NACA I.
NACA I	Minor disturbance. No medical intervention is required.	E.g. slight abrasion.
NACA II	Slight to moderate disturbance. Outpatient medical investigation, but usually no emergency medical measures necessary.	for example, fracture of a finger bone, moderate cuts, dehydration.
NACA III	Moderate to severe but not life-threatening disorder. Stationary treatment required, often emergency medical measures on the site	e.g. femur fracture, milder stroke, smoke inhalation.
NACA IV	Serious incident where rapid development into a life-threatening condition can not be excluded. In the majority of cases, emergency medical care is required	for example. vertebral injury with neurological deficit, severe asthma attack; drug poisoning.
NACA V	Acute danger	for example, third grade skull or brain trauma, severe heart attack, significant opioid poisoning.
NACA VI	respiratory and/or cardiac arrest	---
NACA VII	death	---
