Ch. 12 Computers and Technology in Health Care
adenosine stress test
used for patients who cannot exercise; a medication that stimulates the effect of exercise is given to increase the blood flow and heart rate
dobutamine stress test
used for patients who cannot exercise; a medication that stimulates the effect of exercise is given to increase the blood flow and heart rate
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
Health information exchange
allows all health care agencies to readily transfer patient electronic health records between agencies in a national network
mainframe computer
type of computer size ( can control the launch of a rocket to outer space)
computer literacy
a basic understanding of how a computer works and the applications used in your field or profession
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
exercise stress test
an ECG run while the patient is exercising; usually involves walking a treadmill or riding an exercise bike until a target heart rate is reached
image-guided surgery
a surgical procedure in which a surgeon uses preoperative and intraoperative images to guide or direct the surgery
microcomputer
type of computer size (small)
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.
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
fields
areas where information is entered
internet
links millions of computers throughout the world
networks
systems that allowed computers to be linked together
computerized tomography
noninvasive, computerized X-ray permits physicians to see clear, cross-sectional views of both bone and body tissues and to find abnormalities such as tumors or bleeding
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
file
a combined group of related records
lasers
light beams that can be focused precisely
nuclear stress test
uses nuclear magnetic resonance instead of X-ray radiation. Magnetic resonance imaging alters the magnetic position of hydrogen atoms to produce an image. The patient is placed in a large circular magnet which uses the magnetic field to measure the activity of hydrogen atoms within the body.
database
an organized collection of information
electronic mail
the process of sending messages from one computer to another
firewalls
protective programs that limit the ability of other computers to access a computer
magnetic resonance imaging
uses nuclear magnetic resonance instead of X-ray radiation. Magnetic resonance imaging alters the magnetic position of hydrogen atoms to produce an image. The patient is placed in a large circular magnet which uses the magnetic field to measure the activity of hydrogen atoms within the body.
patient portals
secure online websites that are established so that patients can see their own health information
