1. Recommended areas of use, operation concept 1.1. Brief description, main parameters The defibrillator is an instrument serving for stopping the ventricular fibrillation, it is able to change the electric operation of the heart, by applying a high energy impulse. In case of ventricular tachycardia, the defibrillator is able to restore the normal operation, by applying synchronous defibrillation. In case of sinus tachycardia, bradycardia or strong arrythmia, the device is able to normalize the heart operation, in pacing mode. With the adequate electrodes, it is possible to use the device, in case of heart operation, by the impulse delivered directly to the heart. Besides the energy delivery (defibrillation and pacing) the defibrillator can make ECG, and it can measure some other physiological parameters (eg. HR, SPO2, NIBP). In case of external (transcutaneous) defibrillation, the delivered energy can be 2-360 J in 15 steps, in case of internal defibrillation it can be 1-50 J, also in 15 steps. ® In defibrillation mode the device performs STAR biphasic waveform, and in pacing mode it performs rectangular current impulse. 1.1.1. STAR® biphasic waveform It has been prooved about the STAR biphasic waveform during clinical researches made according to FDA guidelines, that it is one of the most effective waveforms for stopping ventricular fibrillation. STAR (BTE) biphasic waveform characteristics: the period of first phase is depending on patient impedance, 3 – 11 ms, the period of second phase is fixed 3,2ms. The amplitude of the signal depends on the set energy and on patient impedance.

1.2. Cases whereby the defibrillator can be used In manual mode Applying asynchronous shock for the treatment of ventricular fibrillation with the assistance of external defibrillator paddles or pads or internal paddles. Applying synchronized shock in case of atrial fibrillation, ventricular tachycardia (cardioversion), with the assistance of external defibrillator electrodes (pads/paddles). ECG, HR, SpO2, NIBP monitoring. Semi-automatic mode The device assists the operator by voice and text (step by step) instructions appearing on the display, in the device operation. The device automatically performs the necessary operations, it charges the defibrillator’s energy, and it gives an instruction for the delivery of shock. Applying of asynchronous shock, in case of recognized fibrillating heart muscle (according to AHA). ECG, HR monitoring.

In pacing mode External pacer, in ’demand’ and in ’fixed’ modes. ECG, HR, SpO2, NIBP monitoring. In ECG mode ECG monitoring on 1, 3, 7, or 12 channels HR, SpO2, NIBP monitoring

1.3. Electrodes, recommended setups The defibrillator paddle electrode of the device can be transformed into pediatric or adult electrodes by only a single rotation, the adhesive defibrillator electrodes and the internal electrodes are available in adult and pediatric sizes as well. The defibrillator can be used for adult and pediatric population. Its application is not recommended for children under the age of 1. For children between the ages 1-8 and under the weight of 25 kg, the application of 2 – 4 J/kg energy is recommended.

1.4. Environment of use The CA360-B defibrillator was primarily made for hospital and clinical use, but it can also be applied during surgeries and by general practitioners as well. In AED mode even a skilled policeman or fireman can operate the device. The device was made for continuous use, but because of the high energy, it must be considered that any defibrillation with greater frequency than two shocks delivery/minute, is only allowed for a short time.

1.5. Who are entitled to operate the defibrillator? The CA360-B defibrillator in semi-automatic mode can be operated by non-professional persons as well, as the defibrillator gives instructions to the operator. Even in such cases, it is advisable that the device should be operated by a person, who has been trained for the use of semi-automatic defibrillators. In case of manual, synchronous and asynchronous defibrillation and in fixed and demand pacing mode, the device can only be operated by a skilled person – physician.

100% adaptation of ERC 2010 BLS-AED recommendation It supports the effort of minimizing CPR interruptions and unintended deliveries of shock, which can cause the injury of the person performing resuscitation. With the defibrillator it is possible to start charging before placing the paddle electrodes on the chest. In this case there is no electric shock hazard, CPR can be continued. When placing the electrode on the chest, charging is finished in quite a short time and the shock can be delivered. According to the recommendation of ERC 2010 the first shock can be set to a minimum level of 150 J. In order to reach high efficiency, we set the energy of CA360-B in AED mode to 200200-270 J, this way most of the time the delivery of the first shock already stops the fibrillation.

Data Update Period, Effect of Data Averaging, and Other Signal Processing: OxiMax Algorithm

The advanced signal processing of the OxiMax algorithm automatically extends the amount of data required for measuring SpO2 and pulse rate depending on the measurement conditions. During normal measurement conditions in the Normal Mode, the SpO2 averaging time is six (6) to seven (7) seconds or approximately three (3) seconds in Fast Mode. Equivalently, the typical pulse rate averaging time is approximately five seconds, independent of response mode. The OxiMax algorithm automatically extends the dynamic averaging time required beyond seven (7) seconds during degraded or difficult measurement conditions caused by low perfusion, signal artifact, ambient light, electrocautery, other interference, or a combination of these factors, which results in an increase in the dynamic averaging beyond the minimum as set by the response mode. If the resulting dynamic averaging time exceeds 20 seconds for SpO2, the algorithm sets the pulse search bit while continuing to update SpO2 and Pulse Rate values every second. As such measurement conditions extend, the amount of data required may continue to increase. If the dynamic averaging time reaches 40 seconds, and/or 50 seconds for pulse rate, a low priority alarm state results: the algorithm sets the Pulse Timeout bit and the module reports a zero saturation indicating a lossof-pulse condition which should result in an audible alarm.

Response Mode

For systems featuring the Fast Mode (NELL-1, NELL-2), this setting dictates the response time (two (2) to four (4) seconds in Fast Mode and six (6) to seven (7) seconds in Normal Mode) applied by the OxiMax algorithm in its calculation of SpO2. The OxiMax algorithm’s calculation of pulse rate is unaffected by the response mode setting. The data storage interval in the oximeter’s trend memory is decreased automatically to two (2) seconds when the oximeter is set to operate in the Fast Mode (the storage interval is four (4) seconds in the Normal Mode).

Test Considerations and Oximeter Accuracy Functional Testers and Patient Simulators

Some models of commercially available bench top functional testers and patient simulators can be used to verify the proper functionality of Nellcor pulse oximeters, sensors, and cables. Reference the individual testing device's operator's manual for the procedures specific to the model of tester used. While such devices may be useful for verifying that the pulse oximeter sensor, cabling, and oximeter are functional, they are incapable of providing the data required to properly evaluate the accuracy of a system's SpO2 measurements. Fully evaluating the accuracy of the SpO2 measurements requires, at a minimum, accommodating the wavelength characteristics of the sensor and reproducing the complex optical interaction of the sensor and the patient’s tissue. These capabilities are beyond the scope of known bench top testers. SpO2 measurement accuracy can only be evaluated in vivo by comparing pulse oximeter readings with values traceable to SaO2 measurements obtained from simultaneously sampled arterial blood using a laboratory CO-oximeter. Many functional testers and patient simulators have been designed to interface with the pulse oximeter's expected calibration curves and may be suitable for use with Nellcor oximeters and/or sensors. Not all such devices, however, are adapted for use with the Nellcor OxiMax digital calibration system. While this will not affect use of the simulator for verifying system functionality, displayed SpO2 measurement values may differ from the setting of the test device. For a properly functioning oximeter, this difference will be reproducible over time and from oximeter to oximeter within the performance specifications of the test device.

Accuracy with Low Perfusion

Reading accuracy in the presence of low perfusion (detected IR pulse modulation amplitude between 0.03% and 1.5%) was validated using signals supplied by a patient simulator. SpO2 and pulse rate values were varied across the monitoring range over a range of weak signal conditions and compared to the known true saturation and pulse rate of the input signals.

4. The Cardio-Aid® 360-B defibrillator maintanance, assigments 4.1. Cleaning of the device Warning! Do not use any aggressive, acidic chemical for cleaning the device, even if they are diluted. Do not use any surface damaging granular material or flammable detergent. Do not sterilize the device and its accessories, only in case it figures in the instructions of the accessory. Clean the defibrillator and the cables with soft cloth or sponge, not with aggressive detergent. During cleaning, make sure that no liquid should enter into the connectors of the device. Pay special attention when cleaning the tube of the blood pressure measurement cuff, because if any water gets into the tube, entering inside the device during the operation of the blood pressure measurement device, it can damage the valve and the compressor. For cleaning you can use alcoholic solution, ammonium solution with water, peroxide solution or any non-aggressive domestic detergents dropped on a dampened sponge.

4.2. Regular and periodic maintenance Continuously make sure that the device and its accessories should be clean and undamaged. Gel and other materials sticked to it, must be cleaned off from the electrodes. The undamaged status of the electrode cables (cable insulation, breaking) must be regularly checked. The battery condition must be followed with attention, if the device indicates the running down of battery, it must be connected to the mains, in order to be replaced. After some years of operation the battery capacity can reduce to that extent that it cannot guarantee the operation conditions described in the technical data. In such cases the device gives an alarm, the battery must be replaced. Battery replacement can only be carried out by a skilled person. Periodically (in 1-2 years) the main parameters of defibrillator must be checked and if needed a calibration must be made. The calibration can only be made by a skilled service person with adequate qualifications. The continuous and reliable operation can be ensured by the allowance of a wake-up test. If we set it, then the defibrillator will automatically turn on once in a day and it will carry out some test examinations. Operation of the wake-up self-test is detailed in section no. Hiba! A hivatkozási forrás nem található.. This test ensures a continuous check-up, in case of errors or operation faults it will immediately give an alarm. The expected lifetime of the device is 8 years.

4.3. Battery handling, maintenance The CA360-B defibrillator works with 3000mAh, NiMH type battery. A fully charged battery would allow minimum 4-hour monitoring, the delivery of 100 shocks at the energy of 270J or 2-hour pacing. The battery capacity level can always be seen on the battery indicator, the explanation of the indicator can be seen in the table of page Hiba! A könyvjelzC nem létezik.. The defibrillator is equipped with an intelligent battery charger circuit, which carries out all the battery related tasks, therefore the operator does not have to worry about it. If the battery capacity level symbol on the screen indicates the low level of battery, then the defibrillator must be connected to the mains power by a mains cable, by this way charging is started. The charging process is shown by the battery charger LED (18) (see section no. 4.3): The device, connected to the mains, indicates its charging capacity level by flashing signals. In case of being completely charged, the LED is continuously enlighted. In case the device is not connected to the mains, the light of the LED is off. After being connected to the mains, the defibrillator still complies with all the safety requirements, so it can be used without any restrictions. The defibrillator, connected to the mains, is able to operate even with completely empty battery or without battery as well. Warning! Even if the defibrillator is out of use, it still has to be connected to the mains, once in every 3 month, to avoid complete run down of the battery. The lifetime of the battery, in case of normal use, is minimum 2 years. During operation and with time the battery capacity reduces, under a certain critical level the defibrillator indicates the necessity of battery replacement.

5. CA 360 B - Dismantling This section provides information about the dismantling and re-assembly procedures for the CA 360 B. The CA 360 B is dismantled in steps braking the unit down into its major components. Note!

The necessary precautions against Electro Static Discharge (ESD) must be taken. This applies to all handling of electrical components as well as printed circuit boards and all service involving dismantling the CA 360 B.

Note!

Before starting dismantle operation you have to shoot down the device, disconnect power cable and wait at least 2 minutes. Before handling High Voltage parts such as HV-capacitor, HV-circuit etc., ensure that there is no voltage using a high voltage probe (1000:1). High-voltage parts are identified with the “Danger High-voltage” symbol. Be very careful when connecting the high voltage probe- avoid touching the terminals and use proper insulation If voltage is present, leave the unit until the HV-capacitor is fully drained. If the capacitor remains charged it can be discharged by connecting a drain resistor e.g. 100kohm, 17W, directly over the HV capacitor terminals for min. 30 sec. Be very cautious when connecting the resistor and use proper insulation. When storing an HV-capacitor, always leave it in a short-circuit state. Re-assembling the CA 360 B taking care that the various rubber seals are seated correctly.

Important

When ever an operation of dismantling and re-assembly of the CA 360 B is carried out, a safety and performance check must be performed. Tools needed: • Torx screwdriver kit. • Hexagon screwdriver kit • Phillips screwdriver kit. • Wire cutter
