High Volt E Stim
| Question | Answer |
|---|---|
| HVPGS | High Volt Pulsed Galvanic Stimulation |
| What type of wave form is high volt? | Twin Peak Waveform |
| Is twin peak a biphasic or monophasic waveform? | monophasic |
| What is the fixed duration for high volt? | 200 microseconds |
| What is the voltage for high volt? | >100 volts, usually from 100-500 volts |
| Is high volt estim comfortable? | Yes high volt is very comfortable. |
| By _____the pulse duration and increaseing the _______ the deeper tissues get stimulated with out damage. | By decreasing the pulse duration and by increaseing the voltage, the deeper tissues get stimulated with out tissue damage. |
| Describe the pulse duration for high volt estim. | the pulse duration is so short that no axons are stimulated. Therefore no contraction is caused. |
| Describe the twin peaks of hiugh volt estim.... | monopolar or monophasic twin peaks. |
| True or false.. HIgh volt frequency is waveforms per second and always described in hertz. | TRUE |
| How many electrodes does high volt use? | three--- 2 active and 1 large dispersive |
| What does pulsed rate control mean? | how many twin peaks that you have going in the body. Usuall between 2-100hz for high volt. |
| What is polarity switch? | it will ether be negative or positive and refers to the active electrode. |
| What does negative polarity do? | softens tissue & is germicidal- kills bacteria |
| What does positive polarity do? | Hardens tissues/healing wound get to close skin |
| Do you use positive or negative high volt for edema in the ankle? | use the negative polarity to soften the skin and help remove the fluids from the area. |
| What is high volt mostly used for? | wound healing |
| Why is high volt good for wound healing? | Because it is selective. whirlpool and pulsed lavage are nonselective tools for wound healing . |
| Which electrode polarity kills bacteria? | the negative polarity kills bacteria. |
| Can you place the electrode on top of the wound? | Yes & No You can place them on top of the wound only after you place a very wet sterile gauze ofver the wound first. |
| Where does the dispersive electrode go for high volt? | any where else on the body...it is very large so might need to go on the back or belly. |
| What do you want to do before you close up the wound with the high volt machine? | you want to make sure that you have killed all of the bacteria first. |
| What is the treatment time for high volt? | usually between 20-60 minutes. |
| To use high volt you need ______ _______ of the wound. | Good Documentation color, size, smell in order to justify and document progress. |
| After a wound is bacteria free what do you do? | Do another 3 more treatments with the negative polarity to make sure and then get another bacteria culture to make sure still gone. Then switch over to + polarity and start to close the wound. |
| What type of polarity helps close the wound? | + polarity |
| Where do you place the electrodes when you want to close up the wound? | Place the electrode on the wet gauze at the edges of the wound so the healing can start around the edges and then close in. |
| Should the patient feel anything with high volt? | No they probably will not feel any thing because the nerve endings are so far gone. |
| Do you have to stay with the patient the whole time with high volt? | no you don't need to stay with them. |
| What are the contrindications for high volt? | pacemaker, cardiac problems, over metal, pregnancy, want to get pregnant, over eyes, heart ect... PVD, cancer |
