    Given a binary health monitoring profile where each bit represents a specific vital sign monitoring status (0 for inactive, 1 for active), develop a function that activates the leftmost inactive monitoring parameter by setting its corresponding bit to 1. The activation of the leftmost unmonitored parameter ensures the earliest possible detection point in the sequential health monitoring system is enabled for enhanced disease surveillance.
