    摘要: The invention automatically adjusts the parameters that map pressures at a monitoring site, such as blood pressures in the chamber of a heart, to digital values. Adjusting the mapping parameters keeps the data in range while preserving sensitivity. A histogram of the digital pressure data is generated and the contents of the lowest and highest bins of the histogram are checked. Depending on whether the boundary bins of the histogram are full or empty, the mapping parameters are adjusted. A new histogram is generated using digital values generated with the adjusted mapping parameters.
