Lasers Flashcards
1
Q
LASER acronym
A
light amplification by the simulated emission of radiation
2
Q
pros to laser use
A
- precise
- minimal edema
- minimal bleeding
- only one wavelength
3
Q
3 components of a laser
A
- laser medium: contains atoms to create laser light, determines wavelength
- optical cavity: enhances laser with feedback mirrors
- pump source: external energy source
4
Q
wavelength: depends on and effects on
A
- depends on: the laser medium
- effects on: tissue depends on wavelength
5
Q
types of lasers (4)
A
- argon-gas: microscope, endoscope
- KTP-gas: fiberoptic, scanners, microscopes
- CO2
- nd:YAG
6
Q
CO2 laser
A
- ENT and otolaryngology
- can cause corneal injury: clear goggles
- very precise
- long wavelength
7
Q
ng:YAG gas laser
A
- ENT and ophthalmology
- shorter wavelength=deeper penetration
- burn retina: green lens
8
Q
laser concerns and precautions
A
- fire hazard: minimal FiO2
- eye damage: glasses
- noxious fumes: CO2 laser has the most, use evacuator and special masks
- close door and cover windows
- use laser resistant ETT if in airway
9
Q
laser glasses
A
- CO2 = clear
- ng:YAG = green
- argon and KTP: amber orange
