Abstract:
A pulse and respiration synchronous detection system is designed to explore the changes of physiological signals in different situations.The system obtains the corresponding signal through STM32 control pulse and respiratory acquisition circuit,calculates and displays real-time parameters such as heart rate and respiratory rate,and transmits the data to the upper computer for storage in the database.The experimental test results show that the system can monitor pulse and respiratory waveform in different situations,and the waveform is in good condition.Compared with medical pulse oximeter,the error of measured heart rate and blood oxygen concentration is less than 3%,and the error of respiratory rate is less than 5%compared with the actual value,which verifies the accuracy of system signal acquisition.The system is small in size,low in cost,and comfortable to wear,and can be applied in experimental research related to pulse and respiratory signals.
