Ch. 12 Computers and Technology in Health Care
Adenosine stress test
A diagnostic test that uses adenosine to stress the heart and measure how it functions under pressure.
Database
An organized, structured collection of data stored on a computer, designed for easy retrieval and management.
Electronic mail (e-mail)
A digital method of exchanging messages between individuals over a network.
Firewalls
Network security systems that monitor and control incoming and outgoing network traffic based on predetermined security rules.
Magnetic resonance imaging (MRI)
An imaging technique that uses strong magnetic fields and radio waves to create detailed images of organs and tissues.
Computer literacy
The basic knowledge and skills needed to use computers and software effectively.
Dobutamine stress test
A diagnostic test using the medication dobutamine to stress the heart to evaluate its function.
Ergonomics
The study of designing equipment, furniture, and workspaces to maximize efficiency and comfort for the user.
Health information exchange (HIE)
A system that enables the secure electronic sharing of patient health-related information among different healthcare organizations.
Mainframe computer
A large, powerful computer capable of handling massive amounts of data and processing tasks for many users simultaneously.
Computer-aided design (CAD)
Software used by architects, engineers, and designers to create precise technical drawings or 3D models.
Echocardiogram
A medical test using ultrasound waves to visualize the structure and function of the heart.
Exercise stress test
A diagnostic test that measures how the heart performs during physical activity (usually on a treadmill or stationary bike).
Image-guided surgery (IGS)
Surgical procedures performed with the assistance of real-time imaging technology to guide instruments precisely.
Microcomputer
A small, relatively inexpensive computer designed for individual use, such as a desktop or laptop.
Computer-assisted instruction (CAI)
The use of software programs or computer systems to aid in the teaching and learning process.
Electrocardiogram (ECG):
A test that records the electrical activity of the heart over a specific period of time to detect abnormalities.
Fields
In a database, these are the individual, specific categories of data (e.g., "Patient Last Name," "Blood Pressure").
Internet
The global system of interconnected computer networks that communicate using standardized protocols.
Networks
Groups of computers or devices linked together to share resources, data, and communication.
Computerized tomography (CT)
An imaging procedure that uses X-rays and computer processing to create cross-sectional images (slices) of the body.
Electronic health record (EHR)
A digital, secure version of a patient's medical history, including diagnoses, medications, and treatment plans.
File
A single, named unit of data stored on a computer system.
Lasers
Devices that emit intense beams of light, used in medicine for precision surgeries and treatments.
Nuclear stress test
A test that uses a small amount of radioactive material to visualize blood flow to the heart muscle.
