    Develop a function for the patient monitoring system that transforms vital sign parameter names from the database's underscore notation to the standardized camelCase format used by the clinical interface modules. The function must handle any length of medical parameter identifiers, preserving all characters except underscores while ensuring proper capitalization of subsequent words. This standardization is crucial for seamless data exchange between the vital signs monitoring database and real-time patient assessment interfaces.
