BME EXAM 2 Questions & Answers
(Grade A+)
State the purposes of these classes of devices and specify the time
frame when each technology started to emerge: implantable
cardiac pacemakers -
correct answer ✅1950s Medtronic, helps control abnormal
rhythms, uses electrical pulses to prompt the heart to beat at a
normal rate
State the purposes of these classes of devices and specify the time
frame when each technology started to emerge: cochlear implants -
correct answer ✅1960s hearing; mimics the hairs in the cochlea,
tells the person what sounds are at what frequency, two parts: one
behind ear, other under skin, replaces the normal acoustic process
with electrical signal
State the purposes of these classes of devices and specify the time
frame when each technology started to emerge: Holter Monitors -
correct answer ✅1960s wearable ECG; battery operated ECG that
records continuously, the actual device would hang from a person's
neck and is the size of a small camera, and had electrodes
connecting to skin
State the purposes of these classes of devices and specify the time
frame when each technology started to emerge: Wearable CGM
systems -
,BME EXAM 2 Questions & Answers
(Grade A+)
correct answer ✅2010 continuously take readings of blood glucose
levels and detect when more insulin or glucose is needed, getting
closer to a closed loop system, filament/wire in the interstitial fluid
under the skin
State the purposes of these classes of devices and specify the time
frame when each technology started to emerge: FitBiT -
correct answer ✅2010 track daily exercise, heart rate, pulse rate,
etc. at all times of the day. Raises overall health awareness, earlier
detection of problems, can send this info the healthcare
professionals
Define the notion of 'autonomy' for wearable medical devices. -
correct answer ✅Autonomy: MOST important device
characteristic, operates on its own as an independent system,
closed loop system so the patient never has to think about it
Explain the role of a wearable system in the context of chronic
disease management. -
correct answer ✅For diseases like heart disease, diabetes, asthma,
etc. wearable systems make it easier to check vitals and take a lot
less time. Patients can constantly be sending information to their
doctor and then if there is a problem found they would go in rather
than check-ups every so often.
, BME EXAM 2 Questions & Answers
(Grade A+)
Note what is novel about the SensoScan clip. -
correct answer ✅SensoScan: finger clip/ring with 17 functions, can
take all vials from home and transfer to phone
Note what is novel about the AliveCor Kardia band. -
correct answer ✅AliveCor: record, store, and transfer single
channel ECG rhythms, compatible with IOS and Android
From a broader perspective, what change in care paradigm do
these devices promote? -
correct answer ✅Care Paradigm: patients are realizing that the
best access point for physician care is once again at home. Devices
such as these are becoming increasingly popular to allow for as
little time possible to be spent in the actual health care facilities.
In terms of wearable device design considerations, explain by
example what is meant by data handling -
correct answer ✅Data Handling: data acquisition and storage
In terms of wearable device design considerations, explain by
example what is meant by signal processing -
