CLASSWORK -Ch. 12 Computers and Technology in Health Care - KEY TERMS
A cardiac test for people unable to exercise; a drug (adenosine) is used to dilate heart vessels to simulate exercise stress.
adenosine stress test
A structured set of data held in a computer, especially one that is accessible in various ways.
database
Commonly known as email; the exchange of digital messages over the Internet.
electronic mail
Security systems that monitor and control incoming and outgoing network traffic based on predetermined security rules.
firewalls
A non-invasive imaging technology that uses powerful magnets and radio waves to produce detailed images of organs and tissues.
magnetic resonance imaging
The knowledge and ability to use computers and related technology efficiently.
computer literacy
A procedure where a drug (dobutamine) is used to stimulate the heart to beat faster and harder, mimicking exercise.
dobutamine stress test
The study of people's efficiency in their working environment, often focused on designing equipment to reduce physical strain.
