Voltage
110 V
units of intensity
mA
wavelength
same as time
15-20
What is the anode vs. cathode used for
anode: attracts O2
acid
hardens
vasoconstricts
Cathode:
attracts H+ (basic)
softens
vasodilates
LVDC electrode is placed in water to test it out. How do I know which one is the anode and which is the cathode
anode: H+ moving toward it (bubbles)
cathode: gives off bubbles
place a lithmus paper in water to test out which electrode is the anode vs. cathode. What color will the paper change
anode: red
Cathode: blue
When phenolphthalein is dropped into the water and turns pink… what electrode is in the water
cathode
how deep does LVDC penetrate?
1in
how deep does ionophoresis penetrate?
1-2mm
what three items should we check for that the pt might be allergic to or using before appling ioniophoresis
salicylate allergy
iodine allergy
using bl thinners: heparin & cummidin
name the 5 negative chemicals that can be used during ionophoresis
acetate chloride iodine salicylate niacin
name the 4 positive chemicals that can be used during ionophoresis
Ca+
Cu
Mg
Zn+
Denervation 1ms rule
for a N/M to depolarize you need a current to flow for at least 1ms
- if tiss is damaged bad enough - HVDC will not work –> use LVDC
Is this modality mono or bipolar?
monopolar- one pad is bigger than the other
