After an ATV accident, a 13-year-old's cardiac output is 6.0 L/min. What does this indicate about their cardiac performance?

A cardiac output of 6.0 L/min for a 13-year-old indicates normal functioning for their age. Normal cardiac output varies with age, with typical values ranging from about 4 to 8 L/min in adolescents, depending on size and activity level. In the case of a 13-year-old, a cardiac output of 6.0 L/min falls well within the acceptable range, suggesting that the heart is effectively pumping blood to meet the metabolic demands of the body.

In the context of an ATV accident, maintaining an adequate cardiac output is crucial for ensuring proper perfusion to vital organs. The value indicates that the cardiovascular system is likely compensating well despite any potential injuries sustained in the accident, thus reflecting normal cardiac performance. This is an important aspect of assessment following trauma, as adequate perfusion is key to recovery and stability.
