Ch. 12 Computers and Technology in Health Care - KEY TERMS
What is adenosine stress test
A test used for patients who cannot exercise, a medication that simulates the effect of exercise is given to increase the blood flow and heart rate
What is database
A database is an organized collection of information, Information is entered into areas called fields.
What is electronic mail
a method of exchanging digital messages between people using electronic devices over a network
What is firewalls
firewalls are protective programs that limit the ability of other computers to access a computer. A firewall alert will usually inform the user that an outside program is trying to access the computer. A strong firewall will prevent some programs and hackers from entering the database, but no firewall is entirely secure.
What is magnetic resonance imaging
Magnetic resonance imaging (MRI): This computerized, body-scanning method uses nuclear magnetic resonance instead of X-ray radiation.
What is computer literacy
Computer literacy means a basic understanding of how a computer works and the applications used in your field or profession.
What is dobutamine stress test
noninvasive diagnostic procedure that uses the medication dobutamine to simulate exercise
What is ergonomics
study of people's efficiency in their working environment
What is health information exchange
enables the secure, electronic sharing of patient health data—such as medical history, medication lists, and lab results—across different healthcare organizations.
What is mainframe computer
high performance computer that is designed for large scale handling
What is computer aided design
Using three-dimensional imaging models, individuals who make prosthetics, or artificial parts, can custom design individualized prosthetics such as hands, legs, fingers, and other body parts that will precisely match the physical requirements of the individual for whom they are designed.
What is echocardiogram
Echocardiogram: uses technology to direct ultrahigh-frequency sound waves through the chest wall and into the heart; a computer then converts the reflection of the waves into an image of the heart; usually a reading is taken while the patient is at rest and then another reading is taken after exercise when the heart rate rises to a target level; used to evaluate cardiac function, reveal valve irregularities, show defects in the heart walls, and visualize the presence of fluid between the layers of the pericardium
What is exercise stress test
an ECG run while the patient is exercising
What is image guided surgery
Image-guided surgery (IGS) is a surgical procedure in which a surgeon uses preoperative and intraoperative images to guide or direct the surgery
What is microcomputer
such as a handheld tablet. smartphone, or personal digital assistant
What is computer assisted instruction
Computer-assisted instruction (CAI) is educational computer programming designed for individualized use. It is user paced, user friendly, and proceeds an orderly, organized fashion from topic to topic
What is electrocardiogram
radiographs; specifies dietary restrictions; and identifies specific nursing care
What is fields
For example, the database may contain information such as name, address, telephone, e-mail address, insurance information, social security number, place of employment, and medical history. Each type of information is a field.
What is internet
global, decentralized network of interconnected computers and devices that use standard protocols (TCP/IP) to communicate, enabling instantaneous data sharing, information access, and communication worldwide
What is networks
Through the use of systems called networks, computers can be linked together. A network can consist of three or four computers linked together in a medical office
What is computerized tomography
Computerized tomography (CT): Introduced in 1972, this noninvasive, computerized X-ray (Figure 12-8A) permits physicians to see clear, cross-sectional views of both bone and body tissues and to find abnormalities such as tumors or bleeding
What is electronic health record
An electronic health record (EHR) is a computerized version of a patient's medical information that may include statistical data (name, address, telephone number, insurance information, etc.), diagnoses, medical history, treatments, medications taken, tests performed, and any other information that could be included in a patient's paper record.
What is file
When a group of related records is combined, this is called a file.
What is lasers
devices that emit highly focused, high-intensity light beams used for precise surgical, therapeutic, and diagnostic procedures
What is nuclear stress test
Nuclear stress test: a small amount of a radioactive substance such as thallium is given intravenously; a special camera is used to identify the rays emitted from the substance while the patient is at rest and then during exercise; allows the physician to evaluate which parts of the heart are healthy and function normally and which parts are not because a less-than-normal amount of the radioactive substance will be seen in areas of the heart with a decreased blood supply
