  2. OUTLINE • Project Overview • Aim & objectives • NI LabView& DAQ System • Design of VIs & user interface • Methodology • Results • Conclusion

  3. Project Overview • Project deals with data acquisition & signal processing of vital signs using NI LabVIEW • Designed algorithms (Virtual Instruments VIs) of heart rate (HR), blood pressure (BP)& pulse oximetry (SpO2) • Firstly, BP is measured using pressure sensor, air cuff & constant air defalting valve • Secondly, our own designed sensor to measure the oxygen saturation, heart rate by using red LED, infrared LED & photodiode • Later, sensor is connected to NI DAQ & measurements are made

  4. Real time Vital Signs monitoring using NI LabVIEW AIM & OBJECTIVES Introduction | Literature Review | Hardware |NI Software & DAQ System| Methodology | Results | Conclusion| • To acquire vital signs (physiological parameters) using biosensors • To interface the obtained data with NI DAQ System which converts it into digital format. • To link the DAQ System with NI LabVIEW and design an algorithm to measure real time data in graphical interface. • Finally, to design & develop a graphical user interface in LabVIEW to display the outputs.

  5. Real time Vital Signs monitoring using NI LabVIEW BLOOD PRESSURE Introduction| Literature Review| Hardware |NI Software & DAQ System| Methodology | Results | Conclusion| • Blood pressure (BP), sometimes it is called arterial blood pressure, is the pressure exerted by circulating blood upon the walls of blood vessels. • During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure. • Measurement Techniques • Invasive (Direct measurement) • Noninvasive (Indirect measurement) • Auscultatory Method • Oscillometric Method

  6. Real time Vital Signs monitoring using NI LabVIEW BLOOD PRESSURE Introduction| Literature Review| Hardware |NI Software & DAQ System| Methodology | Results | Conclusion| • Auscultatory Method • Need Stethoscope • Analog Measurement • Oscillometric Method • Electronic Pressure sensor • Digital Measurement

  7. Real time Vital Signs monitoring using NI LabVIEW BLOOD PRESSURE Introduction| Literature Review| Hardware |NI Software & DAQ System| Methodology | Results | Conclusion| Ranges of Blood Pressure in different Ages

  8. Real time Vital Signs monitoring using NI LabVIEW PULSE OXIMETRY (SpO2) Introduction| Literature Review| Hardware |NI Software & DAQ System| Methodology | Results | Conclusion| • Pulse Oximetry is a device used to measure the oxygen level in our blood. • Our lungs have efficiency to diffuse oxygen into our blood hemoglobin to make it oxygenated hemoglobin (HbO2) and after the exchange of oxygen with Carbon-di-oxide occurs between tissue and blood then the blood becomes deoxygenated hemoglobin (Hb). • Measurement Technique • Oxygenated hemoglobin • Infrared LED • 940nm wavelength • Deoxygenated hemoglobin • Red LED • 660nm wavelength
