The TrueCPR device is intended to provide feedback to assist rescuers to perform cardiopulmonary resuscitation (CPR). Rescuers must be trained in CPR and use of the device. The TrueCPR device is intended for use on patients eight years of age and older.
The TrueCPR coaching device provides rescuers with real-time feedback on chest compressions during cardiopulmonary resuscitations (CPR) in accordance with current guidelines.
This device is a CPR coaching device, meaning it provides real-time feedback on chest compressions. The provided text, however, focuses on administrative information related to the 510(k) submission and does not contain detailed information about the specific acceptance criteria or the study that demonstrates the device meets these criteria.
Therefore, for aspects related to precise performance metrics, sample sizes for test/training sets, expert qualifications, or comparative effectiveness studies, the information is not available in the provided text. The text states that the 510(k) includes documentation related to verification and validation activities but does not elaborate on their specifics.
Based on the provided snippets, here's what can be extracted:
1. Table of Acceptance Criteria and Reported Device Performance
This information is not explicitly provided in the given text. The submission mentions "Performance Standards" and "verification and validation activities supporting the safe and effective use of TrueCPR," but it does not detail specific quantitative acceptance criteria or the device's reported performance against them (e.g., accuracy of depth measurement, rate measurement, etc.).
2. Sample size used for the test set and the data provenance
This information is not available in the provided text. The document refers to "Bench Testing (Comprehensive verification testing)" and "Simulated Use Testing" but does not specify the sample sizes or data provenance for these tests.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
This information is not available in the provided text.
4. Adjudication method for the test set
This information is not available in the provided text.
5. 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
A multi-reader multi-case (MRMC) comparative effectiveness study is not mentioned in the provided text. The device is a "coaching device" to assist rescuers, not an AI-assisted diagnostic tool that would typically involve "human readers." Therefore, the concept of "human readers improve with AI vs without AI assistance" does not directly apply here in the typical sense of interpreting medical images or data.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
The device is explicitly a "coaching device" intended to "provide feedback to assist rescuers," which inherently implies a human-in-the-loop scenario. The text does not describe any standalone algorithm-only performance testing in the context of interpretation or diagnosis. However, "bench testing" and "simulated use testing" would likely involve evaluating the device's ability to accurately measure and provide feedback on CPR parameters independently, but these are not referred to as a "standalone algorithm performance" in the context of diagnosis.
7. The type of ground truth used
The text does not explicitly state the type of ground truth used for specific performance evaluations. For a CPR coaching device, ground truth would typically refer to accurate measurements of compression depth, rate, recoil, etc., obtained through high-precision sensors or standardized testing apparatus in a laboratory or simulated environment, rather than expert consensus, pathology, or outcomes data, which are more common for diagnostic devices.
8. The sample size for the training set
This information is not available in the provided text.
9. How the ground truth for the training set was established
This information is not available in the provided text.
§ 870.5210 Cardiopulmonary resuscitation (CPR) aid.
(a)
CPR aid without feedback —(1)Identification. A CPR aid without feedback is a device that performs a simple function such as proper hand placement and/or simple prompting for rate and/or timing of compressions/breathing for the professionally trained rescuer, but offers no feedback related to the quality of the CPR being provided. These devices are intended for use by persons professionally trained in CPR to assure proper use and the delivery of optimal CPR to the victim.(2)
Classification. Class I (general controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.(b)
CPR aid with feedback —(1)Identification. A CPR Aid device with feedback is a device that provides real-time feedback to the rescuer regarding the quality of CPR being delivered to the victim, and provides either audio and/or visual information to encourage the rescuer to continue the consistent application of effective manual CPR in accordance with current accepted CPR guidelines (to include, but not be limited to, parameters such as compression rate, compression depth, ventilation, recoil, instruction for one or multiple rescuers, etc.). These devices may also perform a coaching function to aid rescuers in the sequence of steps necessary to perform effective CPR on a victim.(2)
Classification. Class II (special controls). The special controls for this device are:(i) Nonclinical performance testing under simulated physiological or use conditions must demonstrate the accuracy and reliability of the feedback to the user on specific compression rate, depth and/or respiration over the intended duration, and environment of use.
(ii) Labeling must include the clinical training, if needed, for the safe use of this device and information on the patient population for which the device has been demonstrated to be effective (including patient size and/or age limitations,
e.g., adult, pediatric and/or infant).(iii) For devices that incorporate electrical components, appropriate analysis and testing must demonstrate that the device is electrically safe and electromagnetically compatible in its intended use environment.
(iv) For devices containing software, software verification, validation, and hazard analysis must be performed.
(v) Components of the device that come into human contact must be demonstrated to be biocompatible.
(vi) Human factors testing and analysis must validate that the device design and labeling are sufficient for effective use by the intended user.

Premarket notification. The CPR Aid with feedback device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter if it does not contain software (e.g., is mechanical or electro-mechanical) and is in compliance with the special controls under paragraph (b)(2) of this section, subject to the limitations of exemptions in § 870.9.
