Chapter 6: Patient Care and New Technologies Flashcards
patient identifying markers
patient’s name
medical record number
date of birth
influence many aspects of patient care and ensure that patient records are kept private by establishing certain standards or safeguards
HIPAA
Documentation required on images:
patients name and other identifying information
facility information
date of examination
image orientation
transfer of information from one person to another
communication
communication can be:
verbal or nonverbal
signs, hand gestures, facial expressions, and other body motions
nonverbal communication
loss of consciousness
loss of blood pressure
dilation of pupils
possibly seizures
classic presentation of cardiac arrest
body’s pathologic response to illness, trauma, or severe physiologic or emotional stress
shock
transmitted via contact with infectious blood, semen, and other body fluids, sex, sharing needles, during childbirth
Hepatitis B and C
virus that leads to AIDS
HIV
airborne disease found in lungs
tuberculosis
staphylococcus or “staph” bacteria that is resistant to many antibiotics; infected area on skin
MRSA
hospital-acquired infection
nosocomial infection
Most common nosocomial infection
UTI
complete removal or microorganisms and their spores from an object or surface
sterile technique
calculation used to predict the maximum temperature elevation in tissues as a result of attenuation; maximum heating of tissue related to sound beams spatial peak temporal average
thermal index
action of an acoustic field within a fluid to generate bubbles
cavitation
produces bubbles that oscillate, or fluctuate, in size, but do not rupture
stable cavitation
potential of causing most biologic damage; larger bubbles produced and subsequently ruptured
transient cavitation
likelihood of cavitation to occur
mechanical index
uses sound waves to virtually palpate lesions in the body to evaluate stiffness
elastography
measures tissue strain or change in tissue length as a result of compression
strain elastography
uses acoustic radiation force to compress soft tissue; provides a qualitative measurement of stiffness without requiring pressure input
acoustic radiation force impulse elastography
also referred to as transient elastography; utilizes shear waves to analyze stiffness of tissue
shear wave elastography
agents help with visualization of blood vessels and may be used to identify neoplasms
contrast enhanced ultrasound
Typical CEUS agent is a microbubble smaller than __ um
10
technique that images at half the fundamental frequency in order to suppress the tissue information and better display microvessels
subharmonic imaging
enables simultaneous display of real-time sonography and a stored CT or MRI
Fusion imaging or hybrid imaging
procedure that pairs a miniature ultrasound transducer and a vascular catheter
intravascular ultrasound
scientific study of creating tools and using equipment effectively in order to help the human body adjust to the work environment
ergonomics
prevention of WRMSDs
proper body mechanics
creating a practical work environment
using equipment that is functionally supportive
Most common location of WRMSDs
shoulder
Scanning arm should be no more than ___ degree abduction
