| IR Dose |
18-20min |
| IR Tests |
Erythema Ab Igne - red blotchy/mottled splotchy d/t continual exp to heat radiation |
| Heat Therapy bath - Indicators |
Arthritis, chilblains, contusions, fx's, peripheral vascular dz |
| Heat Therapy bath - Type |
Parafin - mineral oil to lower melt pt and for ease remove; Hot bath 98-105F |
| UV 0 degree Erythema |
SED no red |
| UV 1 degree Erythema |
MED |
| UV 2 degree Erythema |
1st deg sunburn - peeling redness |
| UV 3 degree Erythema |
2nd degree w/ blistering |
| UV 4 degree Erythema |
3rd degree Sunburn w/ swelling Severe |
| UV Cosine Law |
optimum effect of ratiation occurs when the part to be treated is at right angles to the source AKA Angulation of the rays |
| UV Inverse square law |
Intensity of radiation from source varies inversely wth the square of the distance from the source |
