Redux® Electrolyte Gel 65-04 – Conductive Gel for ECG and Defibrillation

Redux Electrolyte Gel by Parker Laboratories is a highly conductive, non-abrasive, water-based contact medium recommended for routine ECG/EKG procedures and defibrillation applications in which the electromedical equipment manufacturer permits or requires a separate conductive gel.

The smooth, non-gritty formulation helps establish an electrical interface between the patient’s intact skin and a compatible electrode, paddle, or other electromedical component. It is water-soluble and non-staining for straightforward cleanup after the procedure.

Redux Gel is supplied in a 114 g/4 oz tube under Parker Laboratories' product number 65-04. It is a nonsterile product intended for external use on intact, unbroken skin. 

Important: Always follow the instructions supplied with the ECG, defibrillator, electrode, paddle, or other electromedical device. Do not add Redux Gel beneath a pre-gelled or self-adhesive electrode unless the equipment manufacturer specifically permits it. Parker’s IFU directs users to the connected device’s instructions for product-specific application guidance.

What is an electrolyte gel?

An electrolyte gel provides a conductive interface between the skin and compatible electromedical equipment. Dry skin and air gaps can interfere with electrical contact; a properly selected conductive medium helps create more complete contact between the patient and the electrode or paddle.

Redux Gel is formulated for two manufacturer-listed uses:

The product does not generate, measure, or control electrical output. It only serves as the contact medium. Equipment settings, electrode placement, energy selection, and procedure technique remain governed by the connected medical device and clinical protocol. users to consult the electromedical device manufacturer’s directions. 

When Redux Gel is appropriate:

Redux Gel is most relevant when:

• The ECG system uses reusable or non-pregelled electrodes that require a separate conductive medium.

• A defibrillator uses compatible reusable paddles or another system whose instructions call for an electrolyte gel.

• A smooth, non-abrasive contact medium is preferred.

• The procedure does not require an adhesive paste.

• Easy water-based cleanup is important.

• The clinician does not need the skin-abrasion properties of Redux Paste or NuPrep.

It should not be assumed necessary for every ECG or defibrillation system. Many disposable electrodes and multifunction pads already contain an integrated conductive hydrogel. Follow the specific electrode and equipment instructions rather than adding gel automatically.

What Redux Gel is not

For TENS or other stimulation workflows, use Spectra 360 Electrode Gel or compatible pre-gelled electrotherapy electrodes. Spectra 360 is suitable for ECG, TENS, monitoring, and other electromedical uses, but not for defibrillation. 

Redux Gel vs. Redux Creme vs. Redux Paste

The three Redux products are related, but they should not be treated as interchangeable.

Redux Gel is non-abrasive and is recommended for routine ECG and defibrillation. It describes Redux Creme as bacteriostatic and intended for routine ECG but not defibrillation, while Redux Paste is bacteriostatic, abrasive, and intended for short-term monitoring, ECG, and defibrillation. 

Choose Redux Gel when:

• Routine ECG or compatible defibrillation is the procedure.

• A non-abrasive gel is required.

• Smooth application and water-based cleanup are priorities.

• Adhesive or abrasive characteristics are unnecessary.

Choose Redux Creme when:

• The procedure is a routine ECG.

• A cosmetic-quality cream consistency is preferred.

• Defibrillation is not part of the intended use.

• The clinician wants a bacteriostatic cream formulation.

Choose Redux Paste when:

• Short-term monitoring is part of the application.

• An abrasive conductive paste has been selected.

• ECG or compatible defibrillation use is required.

• A thicker paste consistency is preferred.

Redux Gel compared with other conductive media

SignaGel is a broader multipurpose option for ECG, defibrillation, biofeedback, and EMG. Spectra 360 is salt- and chloride-free and suited to longer applications but is specifically excluded from defibrillation. Tensive provides adhesive performance for procedures such as TENS, EMG, and EEG but is also excluded from defibrillation.

Redux Gel vs. SignaGel

Choose Redux Gel when routine ECG and permitted defibrillation are the principal applications. Choose SignaGel when the facility also needs a labeled conductive gel for EMG or biofeedback. 

Redux Gel vs. Spectra 360

The critical decision is whether defibrillation is part of the workflow. Redux Gel is listed for defibrillation, while Spectra 360 is specifically not indicated for it. 

How to use Redux Electrolyte Gel

There is not one universal application amount or placement method provided because the procedure depends on the ECG, defibrillator, electrode, or paddle being used. The manufacturer instructs users to follow the connected electromedical device’s directions. 

A compliant page-level workflow is

1. Review the equipment instructions. Confirm that a separate conductive gel is permitted and identify the required amount and placement.

2. Inspect the tube. Do not use it if the package is damaged or there is evidence of contamination.

3. Inspect the application site. Redux Gel is intended only for external use on intact, unbroken skin.

4. Avoid contaminating the container. Do not allow the tube tip to touch the patient, staff, electrodes, paddles, or instruments.

5. Apply according to the device instructions. Use only the amount and placement specified by the equipment manufacturer or clinical procedure.

6. Perform the procedure. Follow all ECG or defibrillator operating, placement, energy-selection, and monitoring instructions.

7. Remove residual gel. Redux can be removed with a moistened soft cloth.

8. Close and store the tube. Protect the product from direct sunlight.

Safety, handling, and storage

Nonsterile. For external use only on intact, unbroken skin. Do not use on patients with a known sensitivity to parabens. Discard the product if the package is damaged or contamination is suspected. Do not allow the tube tip to touch the patient, staff, electrodes, or instruments. Use only as permitted by the connected electromedical device’s instructions.

Infection-control considerations

Redux Gel is supplied in a multiuse tube. The container tip should never contact a patient, electrode, paddle, instrument, glove, or other potentially contaminated surface.

For cleaner dispensing:

• Dispense the required amount without touching the treatment surface.

• Do not return unused gel to the tube.

• Close the tube promptly.

• Discard the product if contamination is suspected.

• Follow the facility’s multiuse-gel and infection-control policy.

• Do not use nonsterile Redux Gel where a procedure requires sterile contact media.
