OBJECTIVES:
To study about the different bio potential and its propagation
To understand the different types of electrodes and its placement for various recording
To study the design of bio amplifier for various physiological recording
To learn the different measurement techniques for non-physiological parameters.
To familiarize the different biochemical measurements.
UNIT I BIO POTENTIAL GENERATION AND ELECTRODES TYPES 9
Origin of bio potential and its propagation. Types of electrodes – surface, needle and micro electrodes and their equivalent circuits. Recording problems – measurement with two electrodes
UNIT II BIOSIGNAL CHARACTERISTICS AND ELECTRODECONFIGURATIONS 9
Biosignals characteristics – frequency and amplitude ranges. ECG – Einthoven‟s triangle, standard 12 lead system. EEG – 10-20 electrode system, unipolar, bipolar and average mode. EMG– unipolar and bipolar mode.
UNIT III SIGNAL CONDITIONING CIRCUITS 9
Need for bio-amplifier – differential bio-amplifier, Impedance matching circuit, isolation amplifiers, Power line interference, Right leg driven ECG amplifier, Band pass filtering
UNIT IV MEASUREMENT OF NON-ELECTRICALPARAMETERS 10
Temperature, respiration rate and pulse rate measurements. Blood Pressure: indirect methods – Auscultatory method, direct methods: electronic manometer, Systolic, diastolic pressure, Blood flow and cardiac output measurement: Indicator dilution, and dye dilution method, ultrasound blood flow measurement.
UNIT V BIO-CHEMICAL MEASUREMENT 8
Blood gas analyzers and Non-Invasive monitoring, colorimeter, Sodium Potassium Analyser, spectrophotometer, blood cell counter, auto analyzer (simplified schematic description).
TOTAL: 45 PERIODS
