  1. 1. REAL TIME VITAL SIGN MONITORING USING NI LABVIEW Engr. Narinder Parshad Chowdhry M.Sc. (e-Health & Telemedicine Systems) London, UK Assistant Professor Dept. of Biomedical Engineering Mehran UET, Jamshoro, Sindh 4th International Conference on Transforming Healthcare with IT 6-7th September Hyderabad India
  2. 2. OUTLINE  Project Overview  Aim & objectives  NI LabView & DAQ System  Design of VIs & user interface  Methodology  Results  Conclusion
  3. 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. 4. AIM & OBJECTIVES  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. 5. BLOOD PRESSURE • 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 Real time Vital Signs monitoring using NI LabVIEW Introduction | Literature Review | Hardware |NI Software & DAQ System| Methodology | Results | Conclusion|

  8. 8. PULSE OXIMETRY (SpO2) Real time Vital Signs monitoring using NI LabVIEW • 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 Introduction | Literature Review | Hardware |NI Software & DAQ System| Methodology | Results | Conclusion|
