Chapter 9: Techniques and Equipment Flashcards
vibratory tremors felt through the chest wall
fremitus
light palpation depth?
1cm
moderate palpation depth?
1 to 2 cm
deep palpation depth?
2 to 4 cm
taping the body with the fingertips of the dominant hand
direct percussion
Places the palm of the non dominant hand flat against the body surface and striking through the non dominant hand with the dominant hand using a closed fist
blunt percussion
hammer or tapping finger used to strike an object
plexor
“measure” the device that accepts the tap or blow from a hammer
pleximeter
Take finger and put another finger (other hand) to use as a barrier and tap on the barrier to hear sound
indirect percussion
loud, high-pitched, drum like tone of medium duration characteristic of an organ filled with air (gastric bubble in stomach or air-filled intestines)
tympany
loud, low pitched, hollow tone of longer duration (normal in lungs)
resonance
abnormally loud, low tone of longer duration that resonance. (air trapped in the lungs)
hyperresonance
high-pitched tone that is soft and of short duration (solid body organs such as liver or stool-filled colon)
dullness
high-pitched tone, very soft, and of very short duration (solid tissue such as muscle or bone)
flatness
softness or loudness of sound
intensity or amplitude
number of vibrations of sound per second
pitch or frequency
length of time of the produced sound
duration
recognizable overtones produced by the vibration
quality
listening to the sounds produced by the body
auscultation
measures the degree of joint flexion and extension
goniometer
measures the thickness of subcanteous tissue
skinfold clippers
detects blood, fluid or masses in body cavities
transilluminator
detect fungal infections of the skin
woods lamp
transmits high-pitched sounds such as lung and heart sounds
diaphragm of stethoscope
detects low-frequency sounds such as heart murmurs
bell of stethoscope
use ultrasonic waves to detect sounds that are difficult to hear with a regular stethoscope (fetal heart sounds & peripheral pulses)
doppler ultrasonic stethoscope
inspect internal eye structures
ophthalmoscope
emits a large, full spot for viewing dilated pupils
large aperture of ophthalmoscope
used for undilated pupils
small aperture of ophthalmoscope
shines a green beam used to examine the optic disc for pallor or hemorrhaging which appears black with this filter
red-free filter of ophthalmoscope
can asses size, location and pattern or lesions
grid of ophthalmoscope
examination of anterior eye and aids in assessing the elevation or depression of lesions
slit of ophthalmoscope
inspect external ear structures
otoscope
