Monitoring And Analysis Of Home Pulse Oxygen Saturation Summary

Physiological signals of pulse and oxygen saturation play an important role in measuring our health indicators.Monitoring pulse and oxygen saturation not only can reduce the incidence of cardiovascular and cerebrovascular diseases,but also keeps abreast of people’s current physical conditions.Based on this purpose,this paper designs a home pulse oximetry monitoring system with excellent practicability which mainly realizes the data communication between the lower computer and the upper computer,and accurately collect the pulse oximetry signals.The total design is mainly composed of the upper computer and the lower computer.The lower computer mainly collects the waveform,selects the Arduino nano as the main control chip,and collects the data through the MAX30100 sensor.Then the lower computer amplifies,filters,and converts the obtained analog signals to the main control chip through AD converter,transmits the digital signal to the upper computer through the Bluetooth 4.0 communication method,and,draws the PBC board finally.The upper computer includes PC and Android.The PC adopts Labview software,which mainly has user login,waveform display storage,historical waveform data playback,waveform printing and other functions.All of the functionsmake playback and printing of stored data,and handing over to the doctor for inspection easily.Besides,developing Mobile App,which implements functions such as user login,data reception,alarm warning,and log reminder,can monitor users in real time with portability and immediacy.Finally,through comprehensive debugging,the real-time communication between the lower computer and the upper computer is realized,which meets the prospective expectation.At the same time,the data is compared with the standard instrument and the absolute error of the system is calculated.The final result is that the system meets the requirements.
