CLASSWORK -Ch. 12 Computers and Technology in Health Care - KEY TERMS
adenosine stress test
A test used for patients who cannot exercise where a medication that simulates the effect of exercise is given to increase the blood flow and heart rate so the physician can determine how the heart responds to stress.
computer literacy
basic understanding of how a computer works, the applications used in your field or profession, and feeling comfortable using a computer for your job needs.
computer-aided design
A system using three-dimensional imaging models that allows individuals to custom design individualized prosthetics, artificial body parts, or models for research.
computer-assisted instruction
Educational computer programming designed for individualized use that is user paced, user friendly, and proceeds in an orderly, organized fashion from topic to topic.
computerized tomography
A noninvasive, computerized X-ray that permits physicians to see clear, cross-sectional views of both bone and body tissues and to find abnormalities such as tumors or bleeding.
database
An organized collection of information.
dobutamine stress test
Similar to an adenosine stress test; a test used for patients who cannot exercise where a medication simulating exercise is given to determine how the heart responds to stress.
echocardiogram
A test that uses technology to direct ultrahigh-frequency sound waves through the chest wall and into the heart, where a computer converts the reflection of the waves into an image of the heart.
electrocardiogram
A computerized interpretation system that produces visual pictures on a computer monitor and a printout of the electrical activity of a patient's heart.
electronic health record
A computerized version of a patient's medical information that may include statistical data, diagnoses, medical history, treatments, medications taken, tests performed, and any other information that could be included in a patient's paper record.
electronic mail
Also called e-mail, it is the process of sending messages from one computer to another.
ergonomics
An applied science used to promote an individual's safety and well-being by adapting to the environment and using techniques to prevent injuries.
exercise stress test
An ECG run while the patient is exercising, usually involving walking a treadmill or riding an exercise bike until a target heart rate is reached to evaluate the function of the patient's heart during activity.
fields
Areas in a database where specific types of information are entered.
file
A combined group of related records.
firewalls
Protective programs that limit the ability of other computers to access a computer.
health information exchange
A national network system that allows all health care agencies to readily transfer patient electronic health records (EHRs) between agencies.
image-guided surgery
A surgical procedure in which a surgeon uses preoperative and intraoperative images to guide or direct the surgery
Internet
The ultimate networked system that links millions of computers throughout the world.
lasers
Light beams that can be focused precisely.
magnetic resonance imaging
A computerized, body-scanning method that uses nuclear magnetic resonance instead of X-ray radiation to alter the magnetic position of hydrogen atoms to produce cross-sectional images.
mainframe computer
A very large computer that can control complex operations such as the launch of a rocket to outer space.
microcomputer
A computer that ranges in size from a handheld tablet, smartphone, or personal digital assistant (PDA), to a laptop in a compact case.
networks
Systems that link computers together and allow multiple users to share the same data or information at the same time.
nuclear stress test
A test where a small amount of a radioactive substance is given intravenously and a special camera identifies the rays emitted from the substance while the patient is at rest and during exercise to evaluate heart function.
