laser

ortho foundations exam 1 material

QuestionAnswer
light amplification of stimulated emission of radiation laser
energy packet photon
neutral particles neuron
positive particles proton
negatively charged particles that orbit the nucleus electron
release of a photon of energy equal to the one that was absorbed spontaneous emission
external power sources causes population inversion stimulated emission
environment of excited electrons population inversion
3 properties that distinguish laser from incadenscent light coherence, monochromaticity, collimation
all photons of emitted light are of the same wavelength in phase with one another coherence
only one wavelength of light is produced monochromaticity
all photons move in a parallel fashion without diversion collimation
types of lasers high or low power
high power used for surgical procedure, output > than 500 W
lower power used for cold laser used for therapeutic effects, output its in mWatts
2 laser techniques gridding or scanning
gridding technique treatment area divided into a grid of cm^2
each cm^2 in gridding ____ is stimulated for a specified time
scanning technique move across whole treatment area over the course of the treatment
disadvantage of scanning don't know how much energy each area is getting
dosage of gridding depends on laser output, surface area of beam, treatment time
default energy dosage for gridding 8 J / cm^2
direct response superficial response from absorption of light
indirect response catalyzed response in deeper tissue
use laser if patient is in _____ stage *primary fibroblastic repair stage
laser helps increase / stimulate ATP production, DNA RNA synthesis, levels of beta endorphins and serotonin, collagen production
laser helps increase tensile strength of healing tissues, reduces edema
laser works by _____ pain control descending
laser protocols for tendonitis 6 J/cm ^2
laser protocol for arthritis 8 J/cm ^2
laser protocol for soft tissue injury 5 J/cm ^2
laser protocol for sprain / strain with edema 7.5 J/cm ^2
laser protocol for myofascial pain 2 J/cm ^2
contraindications for laser application over eyes, over malignancies, 1st trimester of pregnancy
lasers treat ____ (superficial / deep) superficial

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
