    Design a function that determines the minimum buffer size (as a power of 2) required to store patient vital sign measurements, where the buffer size must be large enough to accommodate at least n data points for efficient real-time monitoring. The optimized buffer size ensures seamless processing of critical patient information while maintaining system performance.
