NuPrep - skin preparation, granular EEG and ECG gel - 114g

Medical gels and pastes used for EEG, ECG, sleep diagnostics and EP studies serve three main purposes: skin preparation, electrode application and signal conduction.

 

1, Skin preparation

Dead skin cells, dirt, sweat and grease cause high transmission impedances, sometimes up to several megaohms (M Ω), between the skin and the electrode. Reducing this transfer impedance is essential for optimal measurement.

 

The AASM recommends an impedance below 5 kiloOhms (5 k Ω) and therefore the skin should be cleaned to achieve stable electrical contact and low transient impedance. A preparation gel such as Nuprep is used to clean the skin and achieve the optimal impedance. In case of very oily skin, alcohol wipes (e.g. isopropanol) can also be used to degrease the skin.



2, Conductivity and adhesion

To ensure stable and reliable conduction, electrodes (e.g. Gold Cup electrodes) should be fixed after skin cleansing. For this purpose adhesive/conductive pastes or gels (e.g. Lic2 , EC2 and Ten20) are used. These are of different thicknesses and are applied depending on the type of study (routine or long term lead) and the electrode (gold, Ag/AgCl cup electrodes or EEG system caps).

 

3, Pastes and gels for skin preparation

By default, Nuprep is recommended for skin preparation. The gel is also recommended for sensitive skin, as no skin irritation occurs during application. Nuprep does not contain latex, either as an ingredient or in the packaging. In addition, latex-free gloves are used in the manufacturing process to eliminate contamination. Nuprep is used to clean the skin, reduce impedance and improve conduction in the following tests:



 

EEG tests

Sleep diagnostics and sleep screening

Long-term ECG and short-term ECG

Evoked potential (EP) testing

Cardiac catheter monitoring

ECG telemetry

Cardiac stress testing

Cardiac rehabilitation monitoring

Intraoperative monitoring

Other skin preparation gels, such as Everi and Skin-Pure, are also used for EEG, EMG, EP, ECG and sleep studies.

Glue and conductive paste for EEG testing and sleep diagnostics

 

 

Adhesive and conductive pastes are used to fix electrodes (e.g. gold cup electrodes, silver-silver chloride cup electrodes (Ag/AgCl cup electrodes) or silver cup electrodes) during routine and long-term leads:

 

 

 

Electroencephalogram (EEG)

Electroneurography (ENG)

Brain mapping

Evoked potential (EP) testing

Neurofeedback

Sleep diagnostics and sleep screening (PG and PSG)

Multiple sleep latency test (MSLT)
