## Indications for use
AED mode is to be used only on patients in cardiopulmonary arrest. The patient must be unconscious, pulseless, and not breathing spontaneously before using the defibrillator to analyze the patient's ECG rhythm. In AED mode, the LIFEPAK 12 defibrillator/monitor is not intended for use on pediatric patients less than 8 years old. Manual Defibrillation is indicated for the termination of certain potentially fatal arrhythmias, such as ventricular fibrillation and symptomatic ventricular tachycardia. Energy delivered in the synchronized mode is a method for treating atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia, and, in relatively stable patients, ventricular tachycardia. Noninvasive Pacing is indicated for patients with symptomatic bradycardia or asystole. 12-Lead Electrocardiographv is useful in the early detection and prompt treatment of patients with acute myocardial infarction. Pulse Oximetry is used to check the saturation of oxygen in arterial blood. It is indicated for use in any patient who is at risk of developing hypoxernia. Noninvasive Blood Pressure Monitoring is indicated for detection in trends of hypertension or hypotension. These include patient conditions indicated by abnormalities in various physiologic parameters such as shock, evaluation of perfusion during dysrhythrnias, major fluid shifts, evaluation of response to fluid therapy, and titration of vasoactive and cardiotonic drugs. Noninvasive blood pressure monitoring may be useful during ECG monitoring or for post-defibrillation recovery analysis. End-Tidal C02 monitoring is indicated for detection of trends in the level of expired C02. It is used for monitoring breathing efficacy in acute cardiopulmonary care, for example, to determine if adequate compressions are being performed during CPR or to rapidly detect whether an endotracheal tube has been placed successfully. Invasive Pressure Monitorin2 is indicatcd for use in measuring arterial, venous, intracranial and other physiological pressures using an invasive catheter system with a compatible transducer.
