CLASSWORK -Ch. 12 Computers and Technology in Health Care - KEY TERMS
Adenosine stress test
Adenosine stress test: A diagnostic test that uses an injection of adenosine to dilate coronary arteries, mimicking the effects of exercise to evaluate blood flow to the heart.
Computer literacy
Computer literacy: The basic knowledge and ability to use computers and related technology efficiently.
Computer-aided design
Computer-aided design (CAD): The use of computer systems to assist in the creation, modification, or optimization of a design.
Computer-assisted instruction
Computer-assisted instruction (CAI): An interactive instructional technique whereby a computer is used to present instructional material and monitor the learning that takes place.
Computerized tomography
Computerized tomography (CT): An imaging procedure that uses special x-ray equipment to create detailed, cross-sectional pictures of areas inside the body.
Database
Database: A structured collection of data organized for rapid search and retrieval by a computer.
Dobutamine stress test
Dobutamine stress test: A pharmacologic stress test using dobutamine to increase heart rate and simulate exercise, often used for patients unable to perform physical activity.
Echocardiogram
Echocardiogram: A test that uses high-frequency sound waves (ultrasound) to create live images of the heart.
Electrocardiogram
Electrocardiogram (ECG): A medical test that records the electrical activity of the heart over a period of time.
Electronic health record
Electronic health record (EHR): A digital version of a patient's paper chart, containing their medical history, diagnoses, and treatments.
Electronic mail
Electronic mail: Also known as email, a form of digital communication sent over an internet connection.
Ergonomics
Ergonomics: An applied science that promotes safety and well-being by adapting environments and techniques to prevent injuries.
Exercise stress test
Exercise stress test: A test where a person exercises (usually on a treadmill) while their heart rate, blood pressure, and ECG are monitored to see how the heart responds to physical stress.
Fields
Fields: Specific data categories within a database, such as a name or address.
File
File: A group of related records combined together in a computer system.
Firewalls
Firewalls: Security software or hardware designed to prevent unauthorized access to a computer network.
Health information exchange
Health information exchange (HIE): The electronic movement of health-related information among organizations according to national standards.
Image-guided surgery
Image-guided surgery (IGS): Surgical procedures that use real-time computer-processed images to help the surgeon navigate and perform the operation.
Internet
Internet: A global system of interconnected computer networks.
Lasers
Lasers: Devices that produce intense beams of light which can be used in medical procedures, such as surgery or skin treatments.
Magnetic resonance imaging
Magnetic resonance imaging (MRI): A non-invasive imaging technology that produces three-dimensional detailed anatomical images using magnetic fields and radio waves.
Mainframe computer
Mainframe computer: Large, powerful computers used primarily by large organizations for critical applications and bulk data processing.
Microcomputer
Microcomputer: A small, relatively inexpensive computer with a microprocessor as its central processing unit (e.g., a desktop or laptop).
Networks
Networks: Groups of two or more computer systems linked together to share resources and information.
Nuclear stress test
Nuclear stress test: A test that uses a radioactive tracer and imaging to measure blood flow to the heart at rest and during stress.
