Biomedical Engineering || All Answers Are Correct 100%.
Bioinstrumentation correct answers Transduction and measurement of physiological quantities
Diagnostic instrumentation correct answers Convert information about a living system into a
form that humans can perceive
Transducers are very important
Therapeutic instrumentation correct answers Used to arrest or control a physiological process
Assistive Instrumentation correct answers Make up for diminished or lost funtion
Measurand correct answers The physical quantity, property, or condition being measured
Typical: voltage, current, impedance
pressure, flow, displacement
temperature
chemistry
Transducer correct answers Convert energy from one form to another
Measurand Challenge correct answers Finding a transducable property of the event that
distinguishes it from other events or substances
specificity
Transducer Considerations correct answers must not alter event being measured
minimally invasive
external power supply
Signal Conditioner correct answers Operates on the signal produced by the transducer
Operations: amplify
filter
impedance match (minimize loading, reflection)
digitize
compensate for undesirable transducer characteristics (non-linearity)
reduce noise
Output Objective correct answers Output or convey information in a form that may be
understood by human senses
Types: Visual, auditory, tactile
ECG Leads correct answers Differential measurement between two locations on the body
Einthoven's Triangle correct answers The triangle that the standard leads, I, II, and III form on
the body
12-lead correct answers Standard and aVR, aVF, aVL, v1, v2, v3, v4, v5, v6
QRS-complex correct answers Ventricle depolarization
Ventricle contraction
Atrium repolarization is hidden but occurs
T-wave correct answers Ventricle repolarization
Diagnostic Information correct answers Rhythm
Rate
P-wave amplitude, duration, and shape
PR interval
QRS amplitude, duration, and shape
ST elevation/depression
T-wave size and shape
QT duration
Transducer ECG Considerations correct answers Amplitude linearity,
Amplitude range
Adequate frequency response
Non-biologically reactive
Implantable Device Requirements correct answers Power supply
Size, computational capacity
Biological reactivity
Communication with outside world
Constraints for Bioinstrumentation Design correct answers Measured quantities vary with time
(nonstationary)
Patient-to-patient variation
Complex interactions within physiologic system (often hard to control for)
Safety
Corrosive environment
Making Instruments Smart... correct answers Assist clinicians with simple measures
Greater accuracy and repeatability
Automated diagnosis
Implantable devices
Emergency Personnel
Monitoring outside the clinic
Typically computer-based (CAD)
Automated Detection and Diagnosis Challenge correct answers Identify the unique features that
separate one population (or disease from another)
