BME 200 Exam 2 Questions &
Answers (Grade A+)
Note the difference between passive and active approaches. -
correct answer ✅Passive treatments require the patient to be a
submissive recipient of treatment. Passive treatment can help with
immediate pain relief, but active treatment keeps the patient
functional in the long term
Passive: Extract signals from tissue (monitoring)
Active: Deliver energy to tissue (action, therapy)
Briefly list/describe variations on passive electrode‐based
techniques (i.e., electro*****graphs) -
Compare the shapes of these signals: ECG, EMG, EEG, EGG, and
EOG. -
correct answer ✅EEG Brain Activity: Emotive state (affect), sleep
studies, seizure detection, cortical mapping, anesthesia depth,
coma, stroke,
Electromyograph Circuitry: similar to ECG circuitry, but acquire
signals over a different frequency range (e.g., 50-150 Hz instead of
0.3 to 40 Hz).

Answers (Grade A+)
Electrogastrogram (EGG)BME 200 - Medical Monitoring
Devices79Goal: Assess stomach function (i.e., digestion issues) by
recording electrical signals that control stomach muscle
contractions
Electrooculogram (EOG) - Eye Movement
Electroretinogram (ERG)BME 200 - Medical Monitoring Goal: assess
retinal status and the possible presence of eye disease
Note benefits and challenges of wearable electrode systems. -
correct answer ✅bennifits:
can be worn at all times
can be opperated without a doctor
gives real time data
challenges:
financial reimbursement, device interoperability and the present
lack of the required connected healthcare infrastructure
, BME 200 Exam 2 Questions &
Answers (Grade A+)
Identify applications for which active electrode systems have
proven useful. -
correct answer ✅respiration rate in the nose clip
Explain the physical property that is measured by an EDA (GSR)
system -
correct answer ✅EDA, also known as skin conductance or galvanic
skin response (GSR), is a method of measuring the electrical
conductance of the skin, which varies with its moisture level.
What components are used in a traditional polygraph? -
correct answer ✅The three components of the polygraph
instrument include the cardio-sphygmograph, the pneumograph,
and the galvanograph. Blood pressure and heart rate are measured
by the cardio-sphygmograph component of the polygraph, which
consists of a blood pressure cuff that is wrapped around the
subject's arm.
State applications where neuro stimulation has proved useful. -
correct answer ✅This technology most commonly has been used
to treat painful conditions of the median, radial, ulnar, sciatic,
posterior tibial, and common peroneal nerves. It also has been
used to treat neuralgias of the intercostal, ilioinguinal, occipital,
superior cluneal, supraorbital, and supratrochlear.
