AI/ML Overview

The provided text describes ZOLL M Series with Real CPR Help™ and its functionalities but does not contain detailed information about acceptance criteria and a specific study proving the device meets those criteria, as typically presented in a scientific publication or a dedicated performance evaluation section.

Instead, the document is a 510(k) summary, which focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting a detailed performance study with specific metrics, acceptance criteria, and ground truth establishment as would be found in a clinical trial report.

However, based on the intended use and description of the device, we can infer some implicit performance goals and how the provided text generally addresses them.

Inferred Acceptance Criteria and Reported Device Performance

Criteria Category	Specific Criteria (Inferred from Intended Use)	Reported Device Performance (from text)
CPR Rate Guidance	Accurately provides metronome/feedback for 100 compressions per minute (CPM).

Missing Information (Not provided in the document for a typical performance study):

The document does not detail a specific "study" in the traditional sense of a clinical trial or a statistically powered performance evaluation with primary and secondary endpoints, sample sizes, and ground truth methodologies that are usually associated with AI/ML device performance descriptions. Here's why and what's missing:

Sample size used for the test set and the data provenance: This information is not provided. The document mentions "extensive performance testing" and "functional testing" but does not specify sample sizes (e.g., number of compressions evaluated, number of subjects, or data points) or the origin of any data used for these tests.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: This information is not provided. The device provides feedback based on AHA/ERC guidelines, which are expert-derived, but the document doesn't describe an independent expert ground truth establishment for testing the Real CPR Help's accuracy in delivering those prompts. The "ground truth" here is implied to be the established AHA/ERC guidelines themselves for target rate and depth.
Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable based on the provided text, as no expert adjudication for ground truth is described.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: This is not provided and is not applicable in the context of this device. The device assists rescuers (not "readers") in performing CPR. The document states its intended use is to "encourage rescuers to perform chest compressions" at recommended rates and depths. It doesn't present an effectiveness study to quantify how much rescuers improve with the device vs. without it.
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: The "Real CPR Help" feature is the algorithm, and its performance is inherently tied to providing feedback to a human-in-the-loop. The textual performance descriptions ("provides metronome," "provides feedback," "acquires signals") relate to its standalone function of processing data and generating prompts. However, a formal standalone performance study with specific metrics (e.g., accuracy of rate detection, accuracy of depth detection against a gold standard sensor) is not detailed.
The type of ground truth used (expert consensus, pathology, outcomes data, etc.): The "ground truth" for the feedback mechanism is the AHA/ERC recommended guidelines for CPR rate (100 CPM) and depth (1.5-2 inches). The accuracy of the device would then be measured by how well its internal sensors and algorithms detect and report these parameters, and how effectively its prompts align with these guidelines. The document does not describe the specific methodology for establishing measurement ground truth (e.g., using a high-precision force/motion sensor as a gold standard to validate the device's sensor readings).
The sample size for the training set: This information is not provided. Given the nature of medical device 510(k) submissions for non-AI/ML systems, details about "training sets" are often not explicitly mentioned. The device's functionality likely relies on established signal processing and measurement techniques rather than a "trained" machine learning model in the contemporary sense.
How the ground truth for the training set was established: This information is not provided. Again, for a traditional medical device (before the widespread use of deep learning), a "training set" doesn't typically exist in the same way as an AI/ML model. The device is engineered to meet specific physical and physiological parameters based on established guidelines.

In summary, the provided document is a regulatory submission demonstrating substantial equivalence, not a detailed scientific paper on device performance. It attests to the device's functional integrity and adherence to intended physiological targets (AHA/ERC guidelines) through general claims of "extensive performance testing" and "functional testing" but lacks the granular data and methodological details requested for a comprehensive performance study description.

External Pacemaker (Pacer Version Only)

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 bradycardia 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.
