1 Intended Use The GE Healthcare KISS Multilead Electrode Application System (referred to as the "KISS System" throughout this manual) is a cord-integrated suction system used to assist in the application of ECG electrodes for the recording of resting ECGs. A pump, located in a separate housing or integrated in the ECG unit, produces an adjustable partial vacuum in the electrodes, holding them in place on the skin at the respective electrode sites. Via a common lead, the negative pressure and the electrical signals are conducted from the ECG unit to the electrode distributor. The electrode distributor is equipped with 14 electrode leads (R, L, F, N, C1 to C6, and A1 to A4). It also accommodates the negative pressure control (80 to 220 mbar). The ECG signal leads are equipped with overvoltage protection against defibrillation and HF surgery voltages. Compared with conventional electrodes or disposable adhesive electrodes fitted with leadwires and patient cables, these systems have one disadvantage: disinfection is much more complicated. The suction electrodes have no bacteria filters and pathogenic germs may enter the suction tubing, contaminating disinfected electrodes. The pathogenic germs could also be expelled into the room air by the application system’s pump. For these reasons, the electrode application system should not be used on patients with highly infectious diseases. Disposable adhesive electrodes are the preferred electrodes in these instances. WARNING: RISK OF INFECTION - The KISS suction electrodes are not fitted with bacteria filters. It is not recommended to use the KISS electrode application system on patients with highly infectious diseases. In these cases, disposable adhesive electrodes are the preferred alternative.

3 Operating the KISS System Powering on the KISS system WARNING: HEMATOMAS DUE TO VACUUM - Be aware that excessive negative pressure settings and prolonged electrode application times may provoke hematomas. Change electrode sites, if required. Ensure you determine the correct negative pressure level required in the respective situations. For standard applications, the negative pressure control should be set to the gap in the arrow marker. This setting is sufficient for most resting ECGs, while exercise tests will require a slightly higher setting. When using the system on small children or other patients with delicate skin, do not choose negative pressure settings in the upper range. When connected to DC power, the pump module is automatically in standby mode. The slide control allows any negative pressure between 80 mbar and 220 mbar to be adjusted. With the control set at left stop position, the pump is switched off.

The pump starts up automatically when a new electrode is applied, and it stops again as soon as the selected negative pressure has been reached. See "Applying the Electrodes" on page 11. After this, it will operate only to re-establish the partial vacuum required in the electrode. At the end of the ECG acquisition procedure, set the negative pressure control to the left stop position. Air will be automatically supplied to the system and the electrodes are removed from the patient. After about three seconds, the pump switches off. If you forget to switch the pump off, it will switch off after 20 seconds, but you will have to set the control to the left stop position before applying the electrodes. 2088531-004E

Operating the KISS System

NOTE: To extend the life of the pump, set the negative pressure control to the left stop position when you are done acquiring an ECG. The pump will switch off, the module will go into standby mode, and the energy consumption will be less than 0.5 W.

Applying the Electrodes WARNING: USING FILTER DISKS It is imperative to use the KISS™ electrodes with filter disks. 1.

Clean the application sites with benzine or low-grade alcohol (<50 %). NOTE: High-grade alcohol will dehydrate the patient's skin more than low-grade alcohol.

2.

Remove the epidermal skin layer with pumice or an abrasive pad.

3.

Set the negative pressure control to a center position. Ensure you select a negative pressure setting appropriate for the patient.

4.

Apply a moderate amount of contact spray to the skin at the electrode site. CAUTION: ELECTRODE DYSFUNCTION - Too much spray may prematurely clog the filter disk in the electrode. Do not use electrode cream or gel as these substances may clog the air valve in the electrode distributor. Use only small quantities of spray. Do not spray the contact agent directly onto the electrode. Clean the electrode as required and replace the filter disk.

5.

Place the electrode on the patient and press gently on the electrode's suction cup. Then remove your finger from the electrode's suction cup to generate a negative pressure.

The corresponding air valve opens, and the pump starts up. 2088531-004E

Visual Inspection Inspect the KISS system daily or if you suspect a problem. During the inspection, verify that the KISS system meets the following minimum conditions: • Check the leadwires and leadwire adapters for wear and loose connections. Replace these parts at the first sign of wear. • Check the pins that the leadwires plug into. They should not be bent or loose. Contact GE Healthcare Customer Support for any repairs needed. • Check the KISS system for any damage. Contact GE Healthcare Customer Support for any repairs needed.

Cleaning and Disinfection Overview Proper cleaning and disinfecting prolongs the life of the KISS system. Failure to use the proper cleaning solutions or to follow proper procedures can result in the following: • Appearance of waveforms when not connected to a patient, resulting in false alarms instead of lead failure alarms • Brittle and cracked case • Melting, dulling, or distortion of the case • Total failure, requiring replacement • Unit malfunction • Voided warranty Soiled systems must be separated from non-contaminated systems to avoid contamination of personnel or surroundings.

Cleaning and Disinfecting the KISS System WARNING: SHOCK HAZARD - Disconnect the ECG unit from the power line before cleaning. Use a moist cloth to wipe the equipment surface clean. Do not allow liquid to enter the equipment. When the surface is very soiled, use a mild soap solution or detergent. Never use abrasive cleaners. 14

Cleaning and Disinfection

All disinfectants containing alcohol can be used. CAUTION: EQUIPMENT DAMAGE - Phenol-based disinfectants or peroxide compounds destroy the device labelling. Therefore, they must not be used to disinfect the device surface.

Post-Cleaning Inspection The KISS system should be visually inspected and functionally tested after cleaning for the following items: • Cleanliness. • Damage, including but not limited to corrosion (rust, pitting), discoloration, excessive scratches, flaking, cracks, and wear. • Missing or worn part numbers. • Proper functioning, including but not limited to the quality of ECGs; correct movement of hinges, joints, box locks, handles, ratchets, and couplings; proper alignment of jaws and teeth; and secure fastening of all locking mechanisms. Do not use a KISS system that is not functioning properly, that has unrecognizable markings, that has missing or worn part numbers, or that is damaged. A disassembled KISS system should be reassembled, unless otherwise instructed.

Cleaning and Disinfecting Leadwires • Disconnect the cables from the equipment before cleaning or disinfecting them. To do so, always pull on the plug and not on the cable. • Clean the cable by rubbing it down with a cloth moistened with soap water. Use a disinfectant to disinfect the equipment. CAUTION: EQUIPMENT DAMAGE - Do not immerse cables in liquid. Even when the system is turned off, liquid enters the system,destroying the filter disks and clogging the electrode application system.

Cleaning and Disinfecting Electrodes • If the system is permanently in use, clean the electrodes each day, otherwise every three to seven days. Replace the filter disk (part no. 932 047 75, pkg. of 100 disks) when cleaning the electrodes. • The surface of electrodes with minor contamination can be cleaned with a cloth moistened with water and detergent. • To disinfect the electrodes, wipe them down with a cloth moistened with 80% alcohol. All disinfectants containing alcohol can be used for disinfection. CAUTION: EQUIPMENT DAMAGE - Do not immerse the electrodes in disinfectant or in cleaning solutions. The liquid would destroy the filter disks. 2088531-004E

Cleaning and Disinfection

• For thorough cleaning, disconnect the electrode D from the lead C with a slight twist. • Next, remove the suction cup A and the filter disk B.

• Clean the electrode with water and a detergent. Use a small brush (toothbrush) to remove dirt. CAUTION: EQUIPMENT DAMAGE Do not use pointed metal objects to remove solid particles of dirt from the electrodes as this would destroy the silver/silver chloride layer. Use a small brush instead. Signs of oxidation (black-gray) on the electrode surface do not affect the measurement results. • All commercially available cleaning agents used for surgical instruments are suitable to clean the electrodes. However, do not use metal dishes and take care not to immerse plugs and metal sockets in the solution. • Carefully dry the electrodes. Then reassemble them, fitting a new filter disk.

Storage Use the following guidelines when storing the KISS system: • Store in a dry, well-ventilated area. • Protect the KISS system and leadwires from dust, moisture, insects, vermin, and extremes of temperature and humidity. • Hang the Acquisition Module, using a holder if available. • If leadwires are attached, they should hang straight. • Do not coil leadwires or cables around the KISS system.
