    Develop a function for the hospital's patient monitoring system that converts medical parameter names from the database format (containing underscores) to standardized camelCase notation for consistent display across medical interfaces. The function should take a vital sign parameter name as input and transform it by removing underscores and capitalizing the first letter of each subsequent word except the first one.
