    In an ICU monitoring system, develop a function that calculates the total number of possible composite risk scores from even-indexed combinations of n vital signs. Given n vital parameters being monitored for a patient, compute the sum of all possible combinations taken at even indices (0, 2, 4, etc.) to determine the aggregate risk assessment value.
