Hard paddles are the electrodes commonly used for external, transchest defibrillation. There is a special Apex paddle and a Sternum paddle. For delivery of the defibrillation shock, the paddles are placed directly on the body surface. Before use, however, an ample amount of electrode gel must be spread onto the paddles. Both paddles have a shock button: The shock button on the Apex paddle is used to initiate defibrillator charging; afterwards the defibrillation shock is triggered by pushing both shock buttons. The paddles can also be used to acquire the ECG signal. A smaller contact surface for defibrillation of children is integrated in the paddles (see "Defibrillation of Children" in section 4.2). Electrodes for Internal Defibrillation
d
Figure 2-3.
Electrode for internal defibrillation
Electrodes for internal defibrillation consist of a contact spoon (a, Figure 2-3), a handle b, and a counter nut c. The spoon must match the size of the heart and have full contact with the myocardium. There is a choice of 3 different spoon sizes. The electrodes as well as their connection cable must be sterilized before each use. An internal defibrillation is either performed with two spoon electrodes or with one spoon electrode and a so-called "external counter electrode" (d, Figure 2-3) which is placed under the patient and in the immediate vicinity of the heart. Defibrillator charging and release of the defibrillation shock are initiated with buttons on the device. Disposable Adhesive Electrodes
Figure 2-4.

may result from the use of flammable anesthetics, skin cleansing agents and disinfectants. Also, it is not permitted to operate the defibrillator in an oxygen-enriched environment or in the presence of flammable substances (gas) or anesthetics. Oxygenation in the vicinity of the defibrillation
-
When equipped with the AC power adapter, do not use the defibrillator outdoors because the power adapter is not splash-proof.
-
Before using the device, the operator must ascertain that it is in correct working order and operating condition. In particular, all connectors, electrodes as well as sensors and probes must be checked for signs of damage. Damaged parts must be replaced immediately, before use.
-
When disconnecting the device from the power line, remove the plug from the wall outlet first, before disconnecting the cable from the device. Otherwise there is a risk of coming in contact with line voltage by inadvertently introducing metal parts in the socket of the power cord.
-
As a general rule, utmost caution is advised for intracardiac application of medical technical devices. Great care must be exercised to prevent that conductive parts (connectors, electrodes, transducers) connected to the isolated patient signal input come in contact with other grounded conductive parts, as this could bridge the patient's isolation and cancel the protection provided by the isolated input.
electrodes must be strictly avoided. Temporarily interrupt the oxygen supply.

Putting the Device Into Operation and Performance Check
-
Electrically conductive contact with parts connected to the heart (pressure transducers, metal tube connections and cocks, guide wires, electrode catheters and the metal parts of syringes) must be avoided at all cost. When using devices intracardially, observe these guidelines:
-
always wear isolating rubber gloves;
-
parts with a conductive connection to the heart must be isolated from ground;
-
do not use tube fittings and stopcocks made of metal, if possible;
-
when connecting the heart catheter, observe these guidelines: - the connection must be isolated - all electrodes must be attached to the patient and secured against inadvertent disconnection or they must be isolated and protected against inadvertent contact (otherwise electrodes that become disconnected could bring the patient in contact with ground).
-
When devices are used intracardially, the annual Technical Inspections are mandatory. During intracardiac application of medical electrical devices, a defibrillator and pacemaker, both checked for proper functioning, must be readily available.
-
Ensure that no conductive connection between the patient and bystanders exists during defibrillation.
10
-
The mains plug must be connected to an appropriate power supply with a non-fused earthed wire. If these requirements cannot be guaranteed, connect the device to the ambulance power supply or operate it on battery power.
-
Do not use multiple portable socket outlets (MPSO) to connect the device to the power line.
-
Devices may be connected to other devices or to parts of systems only when it has been made certain that there is no danger to the patient, the operators, or the environment as a result. In those instances where there is any element of doubt concerning the safety of connected devices, the user must contact the manufacturers concerned or other informed experts as to whether there is any possible danger to the patient, the operator, or the environment as a result of the proposed combination of devices. Standards IEC 60601-1-1/EN60601-1-1 must be complied with in all cases.
-
The device (without AC power adapter) is suitable for application in a humid environment provided the regulations concerning drip-proof equipment of IEC 60601/EN 60601 are strictly observed. However, do not defibrillate patients in a very moist or wet environment, unless absolutely necessary. Always dry the defibrillation electrodes and connection cables prior to defibrillation.

Putting the Device Into Operation and Performance Check
-
Warning Equipment Failure - Magnetic and electrical fields are capable of interfering with the proper performance of the device. For this reason make sure that all external devices operated in the vicinity of the defibrillator comply with the relevant EMC requirements. Xray equipment, MRI devices, radio systems, and cellular telephones are a possible source of interference as they may emit higher levels of electromagnetic radiation. Keep the defibrillator away from these devices and verify the defibrillator performance before use.
-
Equipment Failure - Similarly, the defibrillator may disturb equipment operating in its vicinity when charging or delivering the shock. Verify the performance of these devices before use.
-
Suffocation Hazard - Dispose of the packaging material, observing the applicable waste-control regulations. Keep the packaging material out of children's reach.

Caution Equipment Damage, Shock Hazard - Devices intended for emergency application must not be exposed to low temperatures during storage and transport to avoid moisture condensation at the application site. Wait until all moisture has vaporized before using the device.
-
Equipment Damage - Exercise great care when using HF surgery equipment on the patient at the same as the defibrillator. As a general rule, the distance between the ECG and defibrillation electrodes and the HF surgery electrodes should not be less than 15 cm. If this is not ensured, disconnect the electrodes and transducer leads while using the HF surgery device.
-
Equipment Damage - Avoid defibrillating repeatedly into open air or with the paddles shorted together, because the device temperature may increase to an inadmissible level due to the internal safety discharges.

When switched on again, the defibrillator will reactivate the operating mode selected in the setup menu. Date and time of the change of operating modes is stored in the event memory (chapter 11 "Memories of the Marquette Responder® 3000"). If you wish to return to the semiautomatic mode, you will have to turn the device off and on again.

Manual Defibrillation / Non-Synchronized Defibrillation
4 Manual Defibrillation 4.1 Defibrillator Application Guidelines Observe the following guidelines to ensure successful and safe defibrillation. Otherwise the lives of the patient, the user and bystanders are in danger.
Warning
-
-
Defibrillating a patient with normal heart rhythm may induce ventricular fibrillation.
-
Position the patient flat on a hard surface where he is electrically insulated. The patient must not be allowed to come into contact with metal parts, e.g., bed or litter, to prevent unwanted pathways for the defibrillation current which may endanger the assistants. For the same reason, do not position the patient on wet ground (rain, accident in swimming pool). Do not allow the defibrillation electrodes to come into contact with other electrodes or metal parts which are in contact with the patient. The patient's chest must be dry, because moisture can cause unwanted pathways for the defibrillation current. After use of flammable skin cleansing agents, wait until they have completely dried.
-
The operator and all assistants must be briefed regarding the preparations for and execution of defibrillation. All tasks must be clearly assigned. Immediately prior to the shock - interrupt heart massage and artificial respiration, - disconnect tube connections, and - warn bystanders.
-
Ensure that no conductive connection between the patient and bystanders exists during defibrillation.
-
Before delivering the shock, verify that the charged and selected energies are the same.
-
Shock Hazard - Always switch off the device before exchanging the defibrillation electrodes.
18
Pacemaker Patients - Defibrillating a patient with an implanted pacemaker is likely to impair the pacemaker function or cause damage to the pacemaker. For this reason - select the smallest energy level possible for the application, - do not apply the defibrillation paddles in the vicinity of the pacemaker electrodes, - have an external pacemaker at hand, - check the implanted pacemaker for proper functioning as soon as possible after the shock.
Caution -
Equipment Damage - Disconnect transducers and devices that are not defibrillationproof from the patient before delivering the shock.
-
Equipment Damage - Do not defibrillate the patient with a second defibrillator, while defibrillation electrodes (paddles, pads) of the first device are applied. If the use of a second defibrillator is inevitable, disconnect the electrodes from the first device or remove them from the patient.

Manual Defibrillation / Non-Synchronized Defibrillation
4.2 Non-Synchronized Defibrillation Using Paddles • Remove the paddles from their compartments as shown in Figure 4-1.
• Carefully dry the paddles and the handles in particular, if they are wet.
• Apply an ample amount of electrode cream to Figure 4-1.

In the "Autoseq" position of the energy selector, the defibrillator automatically sequences the preset defibrillation energy levels. The level for the 3rd shock is maintained for all subsequent defibrillations. When you set the energy selector again to "Autoseq", the automatic charge sequence starts over. The factory set Autosequence energy levels are the values recommended by AHA/ERC for ventricular fibrillation and pulseless tachycardia. 1st shock with 200 J 2nd shock with 200 J 3rd and all subsequent shocks with 360 J.
• Check that the selected energy is displayed (c, Figure 4-2).
• Apply the paddles on the patient's thorax such that the greatest possible amount of energy flows through the myocardium. The imaginary line connecting the paddle centers should be identical with the cardiac median line (Figure 4-3).
• Press the paddles firmly onto the thorax (the M

Note − If you do not trigger the shock within 30 seconds of charging, the energy will automatically be discharged internally. You will then have to recharge the defibrillator. − When the defibrillator is charged, you can increase and decrease the energy level to any value with the energy selector (without pressing the "Charge" button again). For an internal discharge of the stored energy, set the energy selector to or to "Off".

− the audio signal stops and the delivered energy is displayed for approx. 6 seconds (in place of the available energy), − the recorder prints a 14-second ECG strip (4 seconds before the shock, 5 seconds blanked, 10 seconds after the shock) (configurable); the blanked period of time is indicated by a vertical line on the recording; − the shock delivery is annotated on the stored ECG (also refer to chapter 11 "Memories of the Marquette Responder® 3000"). If the defibrillator cannot store the selected energy so that selected and stored energy values differ, a warning will be displayed. The defibrillation pulse can be triggered all the same. In this situation we recommend to check the batteries first. If the batteries are intact, have the defibrillator immediately repaired.

Shock Counter
Defibrillation of Children
The number of delivered shocks is indicated below the energy value. This counter is reset to 0 when you set the energy . selector to The number of delivered shocks is also shown on the recording strip (Figure 5-5, intervention report d). This counter, however, counts all shocks since the device was turned on and is reset to 0 only when the device is turned OFF.
Warning Damage to Myocardium - Please note that children require less energy for successful ventricular defibrillation than adults. For the first defibrillation shock delivered to babies and small children, select an energy of approx. 2 J/kg body weight. For subsequent shocks, the energy may be increased to 4 J/kg body weight. Risk of Skin Burns - The full electrode must be in contact with the skin surface (use the small contact surface of the paddles / pads for children).
Ending Therapy
• Once therapy has ended, set the energy selector to
for continued monitoring of the patient.
• If there is no need to monitor the patient, switch off the defibrillator by setting the energy selector to "Off".
• Clean the paddles and the device as outlined in chapter 18 "Cleaning, Maintenance".
The paddles have two different contact surfaces; a large one (can be removed) for the defibrillation of adults and a smaller one for the defibrillation of children. Remove the large contact surface for pediatric use:
• Press on the lock button 1 (Figure 4-5). • Slide the contact surface 2 towards the front and take it off the paddle.
• When re-installing it, the large contact surface must audibly click into place.
