Why the study?
Is there a constant linear relation between body surface area and cardiac output or stroke volume in infants and children?
Is there a constant linear relation between body surface area and cardiac output or stroke volume in infants and children?
This study aims to provide necessary data to validate the use of cardiac index and stroke index in infants and children by examining the relationship between cardiac output and body size.
No takes yet. Share an insight, caveat, or question.
Cardiac index validity in pediatrics requires direct testing; cross-sectional data leave open whether body surface area normalizes output linearly.
Jegier et al. (1963) studied this question.
