Crit Care Resusc
-
Despite the growing number of older patients having major surgery, the normal resting values for the cardiac index of older patients remain unclear. We aim to derive a normative value for such patients. ⋯ The normal range of the cardiac index in older patients may be lower than previously reported. Its rate of decline with age is uncertain, but likely between 3.5 and 8 mL/min/m2 per year. Data on the normal cardiac index in people older than 80 years are scant.
