Manual Defibrillation:
Indications: Defibrillation is a recognized means of terminating certain fatal arrhythmias, such as ventricular fibrillation and symptomatic ventricular tachycardia. Delivery of this energy in the synchronized mode is a method for treating atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia, and, in relatively stable patients, ventricular tachycardia.
Contraindications: Defibrillation is contraindicated in the treatment of Pulseless Electrical Activity (PEA) such as idioventricular escape rhythms, and in the treatment of asystole.
Automated External Defibrillation:
Indications: The AED mode is to be used only on patients in cardiopulmonary arrest. The patient must be unconscious, pulseless, and not breathing normally before using the defibrillator to analyze the patient's ECG rhythm.
Noninvasive Pacing
Indications: Noninvasive pacing is indicated for symptomatic bradycardia in patients with a pulse.
Contraindications: Noninvasive pacing is contraindicated for the treatment of ventricular fibrillation and asystole.
Pulse Oximetry
Indications: The pulse oximeter is indicated for use in any patient who is at risk of developing hypoxemia.
The LIFEPAK 20 defibrillator/monitor was created especially for hospitals and clinics for use on "crash carts" as well as for portable emergency response throughout a hospital. The LIFEPAK 20 defibrillator/monitor is equipped with AC power and a backup internal battery. Features of the LIFEPAK 20 defibrillator/monitor include manual and automated external defibrillation, noninvasive pacing, ECG monitoring (3-wire or 5-wire), pulse oximetry, and synchronized cardioversion.
The LIFEPAK 20 defibrillator/monitor has been modified with new setup options in automated external defibrillation (AED) mode to give medical directors or physicians flexibility in establishing their AED protocols including consistency with the recently updated 2005 AHA Guidelines for CPR and ECC.
The provided document describes a 510(k) premarket notification for a modification to the Medtronic LIFEPAK® 20 Defibrillator/Monitor. While it outlines the device's features and intended use, it does not contain specific acceptance criteria or details of a study that proves the device meets those criteria for its modified features.
The modification described is related to "new setup options in automated external defibrillation (AED) mode to give medical directors or physicians flexibility in establishing their AED protocols including consistency with the recently updated 2005 AHA Guidelines for CPR and ECC."
The document states: "The new cprMAX setup options only affect operation in automated external defibrillation mode. Features of the modified LIFEPAK 20 defibrillator/monitor such as the ECG analysis system, defibrillation waveform, pacing, and pulse oximetry are the same as those of the predicate device. Defibrillation technology and functionality of the LIFEPAK 20 defibrillator/monitor has not changed from the previously cleared device."
This implies that for the new setup options, the company is asserting substantial equivalence based on consistency with guidelines rather than presenting a new study with acceptance criteria. For the core functionalities (ECG analysis, defibrillation waveform, pacing, pulse oximetry), they rely on the previous clearances (K033275, K012274) of the predicate device, as those features have not changed.
Therefore, I cannot extract the requested information (1-9) as it pertains to a new study proving performance against acceptance criteria for the modified device, because such information is not present in the provided text. The document focuses on regulatory compliance through substantial equivalence, not on new performance study data for the specific modification.
§ 870.5310 Automated external defibrillator system.
(a)
Identification. An automated external defibrillator (AED) system consists of an AED and those accessories necessary for the AED to detect and interpret an electrocardiogram and deliver an electrical shock (e.g., battery, pad electrode, adapter, and hardware key for pediatric use). An AED system analyzes the patient's electrocardiogram, interprets the cardiac rhythm, and automatically delivers an electrical shock (fully automated AED), or advises the user to deliver the shock (semi-automated or shock advisory AED) to treat ventricular fibrillation or pulseless ventricular tachycardia.(b)
Classification. Class III (premarket approval)(c)
Date PMA or notice of completion of PDP is required. A PMA will be required to be submitted to the Food and Drug Administration by April 29, 2015, for any AED that was in commercial distribution before May 28, 1976, or that has, by April 29, 2015, been found to be substantially equivalent to any AED that was in commercial distribution before May 28, 1976. A PMA will be required to be submitted to the Food and Drug Administration by April 29, 2015, for any AED accessory described in paragraph (a) that was in commercial distribution before May 28, 1976, or that has, by April 29, 2015, been found to be substantially equivalent to any AED accessory described in paragraph (a) that was in commercial distribution before May 28, 1976. Any other AED and AED accessory described in paragraph (a), shall have an approved PMA or declared completed PDP in effect before being placed in commercial distribution.
