In this paper, we introduce a development of clinical admittance or impedence plethysmography breathe wave eliminating instrument which based on MCS─51 processor.Using dual processor paralell processing architecture, it dynamically processes admittance or impedence wave which reflect the status of blood circulation , and eliminates the breathe wave and other physiology interfering signals. This instrument has interfaces for input and output, so it can be connected with various kinds of clinical impedence in...
