Reference Devices

AI/ML (Artificial Intelligence / Machine Learning)

No
The device description mentions a "Shock Predictive Index (AmSA) value" which is a calculated parameter based on the ECG waveform, not an AI/ML algorithm. The software revision allows displaying this pre-existing calculated value in manual mode. There is no mention of learning, training data, or adaptive algorithms characteristic of AI/ML.

Therapeutic

Yes
The device is described as a defibrillator capable of delivering energy to the body, performing synchronized cardioversion, and being used for external cardiac pacing, all of which are direct medical interventions aimed at treating a health condition.

Diagnostic

Yes
The device is described as performing "multiparameter monitoring of patients" and specifically mentions "monitoring various patient vital signs, including: electrocardiogram (ECG), Pulse Oximetry (SpO2), Carboxyhemoglobin (SpCO), Methemoglobin (SpMet), End Tidal CO2, 12-Lead ECG, and Non-Invasive Blood Pressure (NIBP)", which are all diagnostic functions.

SaMD (Software as a Medical Device)

No

The device description clearly states it is a "ZOLL E Series® Defibrillator" and describes various hardware components and functions like delivering energy, using paddles/pads, monitoring vital signs via cables and sensors, and performing pacing. The software revision is an update to an existing hardware device.

IVD (In Vitro Diagnostic)

Based on the provided text, this device is not an In Vitro Diagnostic (IVD).

Here's why:

IVDs analyze specimens from the human body. The intended use and device description clearly indicate that this device is used for direct patient monitoring and intervention (defibrillation, pacing, vital sign monitoring) using external electrodes, pads, and sensors. It does not analyze biological samples like blood, urine, or tissue in a laboratory setting.
The functions described are related to direct patient care. Defibrillation, pacing, ECG monitoring, SpO2, EtCO2, NIBP, and CPR monitoring are all performed on the patient's body or through direct contact with the patient.

Therefore, this device falls under the category of a medical device used for diagnosis, treatment, and monitoring, but not specifically an In Vitro Diagnostic device.

Overview

Intended Use / Indications for Use

Defibrillator Function

The E Series products contain a DC defibrillator capable of delivering up to 200 joules of energy. It may be used in synchronized mode to perform synchronized cardioversion by using the R-wave of the patient's ECG as a timing reference. The unit uses paddles or disposable, pre-gelled, MFE Pads for defibrillation.

The E Series products must be prescribed for use by a physician or medical advisor of an emergency response team. Do not use the unit's AED function on patients under 8 years of age.

Intended Use - Manual Operation

Use of the E Series products in the Manual mode for defibrillation is indicated on victims of cardiac arrest where there is apparent lack of circulation as indicated by these three conditions:

Unconsciousness
Absence of breathing, and
Absence of pulse.

This product should be used only by qualified medical personnel for converting ventricular fibrillation and rapid ventricular tachycardia to sinus rhythm or other cardiac rhythms capable of producing hemodynamically siqnificant heart beats.

In Manual mode, the E Series unit may also be used for synchronized cardioversion to terminate atrial fibrillation (AF) or ventricular tachycardias (VT) by using the R-wave of the patient's ECG as a timing reference. A qualified physician must decide when synchronized cardioversion is appropriate.

The Advisory function should be used to confirm ventricular fibrillation and wide complex ventricular tachycardia (greater than 150 beats per minute) in patients meeting the three conditions indicating lack of circulation (previously listed).

Intended Use - Semiautomatic Operation (AED)

The E Series AED unit is designed for use by emergency care personnel who have completed training and certification requirements applicable to the use of a defibrillator where the device operator controls delivery of shocks to the patient.

They are specifically designed for use in early defibrillation programs where the delivery of a defibrillator shock during resuscitation involving CPR, transportation, and definitive care are incorporated into a medically-approved patient care protocol.

Use of the device in the Semiautomatic mode for defibrillation is indicated on victims of cardiac arrest where there is apparent lack of circulation.

Intended Use - CPR Monitoring

The CPR monitoring function provides visual and audio feedback designed to encourage rescuers to perform chest compressions at the AHA/ERC recommended rate of 100 compressions per minute. Voice and visual prompts encourage a minimum compression depth of at least 1.5 (3.8 cm) or 2.0 inches (5.0 cm), depending on the configuration, for adult patients.

The CPR monitoring function is not intended for use on patients under 8 years of age.

Intended Use - Pacemaker

This product may be used for temporary external cardiac pacing in conscious or unconscious patients as an alternative to endocardial stimulation.

Note: This device must not be connected to internal pacemaker electrodes.

The purposes of pacing include:

• Resuscitation from standstill or bradycardia of any etiology

Noninvasive pacing has been used for resuscitation from cardiac standstill, reflex vagal standstill, drug induced standstill (due to procainamide, quinidine, digitalis, b-blockers, verapamil, etc.) and unexpected circulatory arrest (due to anesthesia, surgery, angiography, and other therapeutic or diagnostic procedures). It has also been used for temporary acceleration of bradycardia in Stokes-Adams disease and sick-sinus syndrome. It is safer, more reliable, and more rapidly applied in an emergency than endocardial or other temporary electrodes.

• As a standby when standstill or bradvcardia might be expected

Noninvasive pacing may be useful as a standby when cardiac arrest or symptomatic bradycardia might be expected due to acute myocardial infarction, drug toxicity, anesthesia or surgery. It is also useful as a temporary treatment in patients awaiting pacemaker implants or the introduction of transvenous therapy. In standby pacing applications, noninvasive pacing may provide an alternative to transvenous therapy that avoids the risks of displacement, infection, hemorrhage, embolization, perforation, phlebitis and mechanical or electrical stimulation of ventricular tachycardia or fibrillation associated with endocardial pacing.

· Suppression of tachycardia

Increased heart rates in response to external pacing often suppress ventricular ectopic activity and may prevent tachycardia.

Pediatric Pacing

Pacing can be performed on pediatric patients weighing 33lbs / 15kg or less using special ZOLL pediatric MFE Pads. Prolonged pacing (in excess of 30 minutes), particularly in neonates, could cause burns. Periodic inspection of the underlying skin is recommended.

Monitor - Intended Use Multi-parameter Monitoring

This product may be used for monitoring various patient vital signs, including: electrocardiogram (ECG), Pulse Oximetry (SpO2), Carboxyhemoglobin (SpCO), Methemoglobin (SpMet), End Tidal CO2, 12-Lead ECG, and Non-Invasive Blood Pressure (NIBP).

ECG monitoring is performed by connecting the patient to the 3 or 5 lead patient cable, MFE Pads, or through the paddles.

SpO2 monitoring is indicated for detecting arterial oxygen saturation of blood and pulse rate for adult, pediatric and neonatal patients who are well or poorly perfusing, during both no motion and patient motion conditions.

SpCO monitoring is indicated for detecting carbon monoxide concentration in arterial blood for adult, pediatric and neonatal patients who are well or poorly perfusing, during both no motion and patient motion conditions.

SpMet monitoring is indicated for detecting oxidized hemoglobin concentration in arterial blood for adult, pediatric and neonatal patients who are well or poorly perfusing, during both no motion and patient motion conditions.

EtCO2 monitoring is indicated for the continuous measurement of end tidal carbon dioxide (EtCO2) and respiration rate for adult, pediatric and neonatal patients.

12 Lead ECG analysis is indicated for the diagnosis and treatment of adult and pediatric patients with acute myocardial infarction or other cardiac arrhythmias.

NIBP monitoring is indicated for the measurement of arterial blood pressure for resting adult, pediatric, and neonatal patients.

Device Description

The ZOLL E Series® Defibrillator, reviewed and cleared by FDA under premarket notification K111594, is designed for all emergent care situations and provides multiparameter monitoring of patients in critical care and transport. The ZOLL E Series combines defibrillation, CPR feedback, ECG monitoring, noninvasive transcutaneous pacing, pulse oximetry (SpO2), end tidal CO2 (EtCO2), 12-Lead ECG monitoring, noninvasive blood pressure measurement and data printing and recording in a single instrument.

The previously cleared Shock Conversion Estimator (SCE), initially reviewed and cleared by the agency under K072923, utilizes Shock Predictive (SPI) as a parameter in the shock advisory algorithm. Shock Predictive Index number is also called "Amplitude Spectral Area (AmSA) value" of the ECG Waveform, developed by the Weil Institute of Critical Care Medicine. In the previously cleared version of the E-Series, when the E Series device is configured to enable the Shock Conversion Estimator (SCE) function, the software compares the calculated Shock Predictive Index (AmSA) against a userconfigurable threshold during shock advisory rhythm analysis. If the rhythm is shockable and the computed index is greater-than or equal-to the pre-configured threshold, the shock advisory algorithm will then issue a "Shock Advised" prompt to the user. If the Shock Predictive Index (AmSA) is less-than the threshold, the shock advisory algorithm will then issue a "Continue CPR" prompt to the user.

With the current application, we are proposing a software revision that will enable the E Series device to display the calculated Shock Predictive Index (AmSA) when used in manual mode with CPR defibrillation electrodes. After the trained rescuer has confirmed the ECG rhythm by manually analyzing the characteristics of the ECG waveform, the rescuer may utilize the displayed Shock Predictive Index (AmSA) value to perform the same function as the Rhythm Analysis Function Shock Conversion Estimator (SCE), reviewed and cleared by the agency under K072923.
