25
depolarization
Na+ channels open
26
repolarization
K+ channels open
27
hyperpolarization of the heart
Na+ channels are slow to open
28
multiposture system
Part of the ECG as a biometric study had an 81.5% TP rate and outperformed the posture aware system in the sitting posture because it had more templates of postures to compare to
29
posture aware system
Part of the ECG as a biometric study had an 80.8% TP rate It was hypothesized to do better because it only had to compare to similar postures (did not perform better)
30
HIPAA
established privacy and security of EHR in the STATES. allows covered entities to adopts new health technologies to improve the quality and efficiency of patient care while still protecting the security and private health information of patients
31
biometrics
the science that measures body characteristics. Used to protect EHR - to ensure only authorized individuals have access to this personal health information
32
Powerline Frequency
caused by low frequency electromagnetic fields whose frequencies, harmonics, sub-harmonics coincide with our brain, heart and cells
33
resonant absorption
how Powerline frequencies interact with primary function of our bodies (at extremely low intensities)
34
electric field
produced around wires, appliances and equipment powered by electricity proportional to the voltage - constant supply (E, V/m)
35
magnetic field
produced around wires, appliances and equipment powered by electricity proportional to the current more variable as they change varying the electric power being supplied
36
Computerized Functional Electrical Stimulation (CFES/FES)
devices delivers low level electrical stimulation directly to muscles that cannot receive these signals from the brain
37
parastep
a CFES | allows paraplegics to walk - temporary means to of achieving functional motivation
38
implantable cardioverter defibrillator
FES - implanted device that monitors HR and send a jolt of electricity when needed
39
implanted neural prosthesis
FES - allows quadriplegics to feed themselves tiny microprocessor implanted in the chest and connected to electrodes wired under the skin to 8 fingers and thumb muscles of the dominant hand
40
breathing pacemaker
Implanted FES that controls breathing by sending electric signals to the phrenic nerce
41
ACTIVA
implanted FES - helps control seizures in epilepsy and control tremors in parkinsons disease by delivering electric signals to the brain
42
neuromove & biomove
implanted FES - uses electrical stimulation to stimulate muscles to avoid atrophy, increases ROM and blood circulation through electrical stimulation of the brain in STROKE patients
43
neuromodulation
a field that helps treats disorders of the central nervous system
44
microdialysis
to see what the body's response is at a cellular level
45
motion monitor
tracks patients movements through real time by placing electrodes on patients - read by magnetic trackers
46
PIPEDA (Personal Information Protection and Electronic Documents Act)
federal legislation concerning the collection, use, and disclosure of personal information by organizations in the course of commercial activities
47
PHIPA (Personal Health Information Act)
legislation in Ontario regarding how health information custodians should be collecting, using and disclosing personal health information
48
Motion monitors
provides 3D real time images of movements by placing electrodes on patient's body allowing movements to be tracked by magnetic trackers
49
PARO
Therapeutic robots that has sensors to track movement. It remembers what causes stroking or slapping caused by owners and changes its behaviour accordingly
50
privacy breach
when health information is collected, used and disclosed without authorization
51
Privacy Impact Assessment
determines whether new technologies, information systems, and proposed programs or policies meet basic privacy requirements
52
health care clearinghouses
*entities covered by certain aspects of HIPAA* | receive non-standard information and process into standard information or vice versa
53
Health care providers (according to HIPAA)
includes all "providers of health care services" and any other person or organization that furnishes, bills, or is paid for healthcare
54
business associate
a person or organization that provides services on behalf for covered entities of HIPAA that include the use or disclosure of personal health information
55
business associate contract
written safeguards to protect the personal health information being used and disclosed byt business associates of the covered entity under HIPAA
56
store-and-forward technology
involves sharing information in a time- and place-independent way over the internet - good for sending photos - inexpensive - good for diagnosis
57
mhealth
real time teleconferencing using mobile devices and other wireless technology
58
computerized tomography colonography
virtual colonoscopy used for teleradiology
59
protected health information (PHI)
health information is protected under HIPAA - past, present, future physical or mental health condition - provision of health care - past, present or future payment for health care and any information that can be used to identify a patient
60
Minimum Necessery
central aspect of the privacy rule of HIPAA. A covered entitiy must take reasonable effots to use, disclose, and request only the minimum amount of protected health information needed to accomplish the intended purpose of the use, disclosure or request
61
Picture Archiving and Communication System (PACS)
an electronic & ideally filmless information system for acquiring, sorting, transporting, storing, &electronically, displaying medical images
