  1. hello,, in the output file, the above graph is the graph which we have obtained through bandpass filter. It is the oscillation graph from which we can find our mean arterial pressure.....For mean arterial pressure we want to find a single maximum peak which is coming near amplitude equals to 2 when the graph is increasing . we want to store that data in a 2d array so that we can compare the voltage level and its corresponding pressure retrieve below one is the graph from Low pass filter....... can u suggest any way if we can find systolic and diastolic pressure from this graph? need your suggestions thankyou .
  2. hello,Sir, hope u r fine.....we are final year students of biomedical engineering currently working on project (Vital Signs Monitoring using LabVIEW). we are measuring 4 parameters i.e temperature, pulse oximeter, heart rate and blood pressure. we are using DAQ card (PXI-6229) for interfacing hardware with LABVIEW. we have to ask certain questions related to our project.... Currently working on Blood Pressure: We are using MPX5050Dp pressure sensor, DC motor and valve. We are doing the programming of blood pressure...we've done the programming of both motor and valve control...and have also acquire pressure sensor voltage and have convert it into mmHg.(also got bp graph)... Sampling frequency =10kHz Sampling rate =10Khz And apply low pas filter and then band pas filter. = low pass filter = 20hz order 6th order butterworth = bandpass filter= 0.5-20hz order 6 butterworth we are getting right graph but we are still unable to find mean arterial pressure (map) and sytolic diastolic pressures. from band pass filter graph we want to acquire the largest amplitude peak (which is map)... we tried different vi to got the largest amplitude but we are failed .... tried • max min array vi • analog max min waveform vi • amplitude and level vi( peak to peak) • Power spectrum and FFT vi for max peak detection • Peak detector and also apply many program but … from all these vi and program we've got amplitude of all peaks in the graph( which we did not want)...we want only one largest amplitude.. we have generated array in which same value comes in each index. but we want to store all positive peaks .. and then retrieve maximum value from that array to find mean arterial pressure..suggest any way to generate different values at a time we need ur help ..plz give some suggestions
