CLASSWORK -Ch. 12 Computers and Technology in Health Care - KEY TERMS
Computer literacy
Computer literacy: A basic understanding of how a computer works and the applications used in a specific profession, as well as feeling comfortable using a computer for job needs.
Electronic Health Record
Electronic Health Record (EHR): A computerized version of a patient's medical information, including history, treatments, and test results.
Exercise stress test
Exercise stress test: An ECG run while the patient is exercising on a treadmill or bike to evaluate heart function during activity.
Computerized tomography
Computerized tomography (CT): A noninvasive, computerized X-ray that permits clear, cross-sectional views of bone and body tissues.
Ergonomics
Ergonomics: An applied science used to promote safety and well-being by adapting the environment and using techniques to prevent injuries.
Database
Database: An organized collection of information.
Health Information Exchange
Health Information Exchange (HIE): A system that allows health care agencies to transfer EHRs between agencies in a national network.
Nuclear stress test
Nuclear stress test: A test where a radioactive substance is given intravenously and a special camera identifies rays to evaluate heart blood supply.
Magnetic resonance imaging
Magnetic resonance imaging (MRI): A body-scanning method that uses nuclear magnetic resonance and magnetic fields to produce cross-sectional images.
Firewalls
Firewalls: Software used to provide computer security.
Fields
Fields: Specific areas within a database where information is entered, such as a name or address.
Patient portals
Patient portals: Secure online websites that allow patients to view their personal health information and communicate with providers.
Dobutamine or adenosine stress test
Dobutamine or adenosine stress test: A test for patients who cannot exercise; medication is used to simulate the effects of exercise on the heart.
Positron emission tomography
Positron emission tomography (PET): A test where a radioactive substance is injected to create 3-D images, helping diagnose heart disease or cancer.
Viruses
Viruses: Malicious programs that can slow down a computer or compromise data.
Record
Record: A collection of related fields within a database (e.g., all fields for one particular patient).
Spreadsheet
Spreadsheet: Software used to perform high-speed math calculations using formulas and numerical data.
Echocardiogram
Echocardiogram: Uses ultrahigh-frequency sound waves to create an image of the heart to evaluate function and defects.
Mainframe computer
Mainframe computer: A very large computer capable of massive tasks, such as controlling a rocket launch.
Uninterrupted power supply
Uninterrupted power supply (UPS): Provides a backup power source if electrical power fails.
File
File: A group of related records combined together.
Electrocardiogram
Electrocardiogram (ECG): A computerized system that produces visual pictures and printouts of the electrical activity of a patient's heart.
Ultrasonography
Ultrasonography: A noninvasive scanning method that uses high-frequency sound waves to create pictures of body parts.
Microcomputer
Microcomputer: Smaller devices ranging from handheld tablets and smartphones to laptops.
Computer-assisted instruction
Computer-assisted instruction (CAI): Educational tools used for teaching health care personnel.
