Warning

Warnings are identified by the WARNING symbol shown above. Warnings alert you to potential serious outcomes (death, injury, or adverse events) to the patient or user.

WARNING: As a user of an AED it is essential that you inform Mediana of any incident where your AED is suspected to have caused a death, serious injury or illness. If you have any suspicions that this is the case inform Mediana directly or through your authorized Mediana dealer.
WARNING: The AED has the capability to deliver therapeutic electrical shocks. The shock can cause serious harm to either operators or bystanders. Caution must be taken to ensure that neither the operators nor bystanders touch the when a shock is to be delivered.
WARNING: The AED has not been evaluated or approved for use in hazardous locations as defined in the National Electrical Code (Articles 500-503). In accordance with the IEC/EN 60601-1 Classifications, the AED is not to be used in the presence of flammable substance/air mixtures.
WARNING: The AED has been designed to work on unresponsive, non-breathing and pulseless* patients. If the patient is conscious or breathing and regain a pulse, do not use the AED to provide treatment. (*checking pulse corresponds to health care provider)
WARNING: Touching the patient during the analysis phase of treatment can cause interference with the diagnostic process. Avoid contact with the patient and keep the patient as motionless as possible while ECG analysis is being carried out. The AED will instruct you when it is safe to touch the patient.
WARNING: Always stand clear of patient when delivering treatment. Defibrillation energy delivered to the patient may be conducted through the patient’s body and cause a lethal chock to those touching the patient.
WARNING: It has been determined that the AED is safe to use in conjunction with oxygen mask delivery systems. However, due to the danger of explosion it is strongly advised that the AED should not be used in the vicinity of explosive gases. This includes flammable anesthetics, concentrated oxygen and gasoline.
WARNING: The identical pad is used for both Adult and Pediatric. The Adult mode must be used on patients over 8 years old. The Pediatric mode must be used on patients less than 8 years old or less than 25 kg (55lb). Do not use the AED on patient less than 1 year old.
WARNING: Proper placement of the pads is critical. Strict observance of pad positioning instructions, as indicated on the labeling and in training, is essential. Care must be taken to ensure pads are adhered to the patients' skin properly. Air pockets between the adhesive pad and skin must be eliminated. Failure in pad adhesion may hinder effectiveness of therapy or cause excessive skin burns to the patient if a shock is applied. Reddening of the skin may appear after use, this is normal.

Cautions

Cautions are identified by the CAUTION symbol shown above. Caution statements identify conditions or practices that could result in damage to the equipment or other property.

CAUTION: The AED may not operate properly if it is operated or stored at conditions outside the ranges stated in this manual.
CAUTION: The AED was designed to be sturdy and reliable for many different use conditions. Ho wever, handling the AED too roughly can damage it or its accessories and will invalidate the warranty. Check the AED and accessories regularly for damage, according to directions.
CAUTION: Before delivering a shock, it is important to disconnect the patient from non-defibrillation protected electronic devices, such as blood-flow meters, that may not incorporate defibrillation protection. In addition, make sure the pads are not in cont act with metal objects such as a bed frame or stretcher.
CAUTION: The pads pouch shall not be opened until immediately prior to use.
CAUTION: Do not use or place the AED in service until you have read the AED Operator’s manual.
CAUTION: Do not use or stack the AED with other equipment. If the AED is used or stacked with other equipment, verify proper operation prior to use.
CAUTION: Handling or transporting the patient during ECG analysis can cause incorrect or delayed diagnosis. If the AED gives a SHOCK ADVISED prompt during such handling or transport, stop the vehicle and keep the patient as still as possible for at least 15 seconds before pressing the Shock button, to allow the AED to reconfirm the rhythm analysis.
CAUTION: Periodic checks of this AED must be undertaken to ensure among other things that the AED is not damaged in any way.
CAUTION: The pads are a single use item and must be replaced after each use or if pouch that seals pads has been broken/compromised in any way. If damage is suspected the pads must be replaced immediately.
CAUTION: Do not use training pads with this AED.
CAUTION: Carefully observe pacemaker patients. Patient history and physical examination are important in determining the presence of implanted pacemaker. Patient pacemakers may reduce the sensitivity of the AED analysis and errors in detecting shockable rhythms.
CAUTION: If the pads are attached to the chest firmly, the AED can analyze the exact ECG and prevent the skin burns. But if the pads are overlapped on the patient chest, the pads will not deliver defibrillation energy properly.
