Stress Electrocardiograph - Intended Use Using the optional ECG module and associated accessories the user can acquire, view, store and print ECG waveforms. Resting Electrocardiograph - Intended Use The same as defined for stress ECG plus the ability to use optional algorithms (MEANS) to generate measurements, data presentations, graphical presentations and interpretive statements on an advisory basis. These are presented for review and interpretation by the clinician. Spirometry - Intended Use Using the optional spirometry module and associated accessories to acquire, view, store and print measures and waveforms of pulmonary function. The spirometer should only be used with patients able to understand the instructions for performing the test. Ambulatory Blood Pressure - Intended Use Using the optional ABP module and associated accessories the user can acquire, retrieve, view, store and print patient ambulatory blood pressure history.

Device Story

CardioPerfect Workstation Software (CPWS) operates on standard Windows-based PCs to manage ECG, ambulatory blood pressure (ABP), and spirometry data. Input signals are acquired via optional hardware modules; software processes these signals to generate waveforms, measurements, and interpretive statements. Clinicians in hospitals or clinics use the software to review advisory interpretations, manage patient records, and export data to EMRs. The system assists in diagnosing and monitoring cardiac and pulmonary conditions. Version 1.6.2 introduces the PEDMEANS algorithm for pediatric ECG interpretation. Output is displayed on-screen or printed for physician review to support clinical decision-making.

Clinical Evidence

Bench testing only. Verification of MEANS and PEDMEANS algorithms against IEC 60601-2-51:2003 requirements. Risk management conducted per ISO 14971. No clinical trials performed; equivalence established via technical comparison and software validation.

Technological Characteristics

Software-based diagnostic workstation for ECG, ABP, and spirometry. Operates on off-the-shelf Windows PCs. Includes MEANS and PEDMEANS interpretive algorithms. Complies with IEC 60601-1, IEC 60601-1-1, IEC 60601-1-2, IEC 60601-1-4, IEC 60601-2-25, and AAMI/ANSI EC11 standards. Software Level of Concern: Moderate.

Indications for Use

Indicated for adult and pediatric patients requiring cardiac screening or diagnostic differentiation (ECG), pulmonary function assessment (spirometry) for symptoms like shortness of breath, cough, or wheezing, and ambulatory blood pressure monitoring for conditions including white coat hypertension, nocturnal hypertension, resistant hypertension, diabetes, or pregnancy-related hypertension. Spirometry contraindication: patients unable to understand test instructions.

Regulatory Classification

### Description of the Device:

CardioPerfect Workstation software is used to create a computer platform on which ECG, ABP, & Spirometry applications can operate within inherent capabilities of an off-theshelf desktop or laptop personal computer utilizing a Windows operating system.

### Intended Use:

The CardioPerfect Workstation software and associated accessories are indicated for the acquisition, analysis, formatting, display, printing and storage of certain physiologic signals, as identified below, for the purpose of assisting the clinician in the diagnosis and monitoring of various diseases and/or treatment regimens. The CardioPerfect Workstation software also provides non-diagnostic functions such as patient management, data security, search tools for patient and/or test records and support for exporting data to Electronic Medical Record systems.

The CardioPerfect Workstation and associated accessories are intended for use by or on the order of a physician in a hospital or clinic setting. The product is designed for use on both adult and pediatric patients, subject to any specific contraindications identified below.

# Stress Electrocardiograph - Intended Use

Using the optional ECG module and associated accessories the user can acquire, view, store and print ECG waveforms.

# Resting Electrocardiograph - Intended Use

The same as defined for stress ECG plus the ability to use optional algorithms (MEANS) to generate measurements, data presentations, graphical presentations and interpretive statements on an advisory basis. These are presented for review and interpretation by the clinician.

{2}------------------------------------------------

### Indications for Use:

# Electrocardiograph - Indications for Use

Indications for electrocardiography range from routine screening of cardiac health in the physician office environment to directed diagnostic differentiation in a hospital cardiology department.

# Spirometry - Indications for Use

Indications for spirometry include, but are not limited to, the following:

### Technological Characteristics:

The Welch Allyn Electrocardiography and Spirometry Products are intended for use by trained operators in healthcare facilities.

The 12-lead ECG interpretive algorithm provides a computer-generated analysis of potential patient cardiac abnormalities, which must be confirmed by a physician with other relevant clinical information.

{3}------------------------------------------------

The optional spirometry module is indicated for use in clinical situation to assess a patient's pulmonary health status and evaluate symptoms, signs, or abnormal laboratory test results.

The CPWS version 1.6.2 is substantially equivalent to the previously released CPWS version 1.5.0 (K.052158). The major difference being the change to intended use. This submission intends to change the indications for use to include interpretive ECG software for the pediation. The previously marketed CPWS version 1.5.0 (K052158) did not provide interpretive software support for patients less than 16 years of age. The Pediatric Modular ECG PEDMEANS Interpretive ECG algorithm developed by P. Rijnbeek, 2007, in Analysis System thesis entitled 'Automatic Interpretation of Pediatric Electrocardiograms', Erasmus University Rotterdam. This PEDMEANS algorithm, is also used in our CP 100™ and CP 200™ ECG device cleared under K072449.

## Summary of Effectiveness:

The Welch Allyn CPWS team has determined that the software "Level of Concern" is Moderate. (See section 10 for CPWS software Level of Concern)

The implementation of the PEDMEANS interpretive software in the CPWS 1.6.2 electrocardiograph device, and its performance, is equivalent in every respect to the implementation of this software in the CP 100™ and CP 200™ submitted to the agency by Welch Allyn and cleared per K072449.

The MEANS algorithms were verified and found to be consistent with the requirements of IEC 60601-2-51:2003, particular requirements for safety, including essential performance, of recording and analyzing single channel and multi-channel electrocardiographs.

All requirements of the recognized and applicable standards are in compliance: EC11 (AAMI/ANSI), UL 60601-1. IEC 60601-1. IEC 60601-1-1. IEC 60601-1-2. IEC 60601-1-4 and IEC 60601-2-25.

Additionally, risk management (risk, SFMEA and safety analysis) activities have been conducted in accordance with ISO 14971 Medical Devices - Application of risk management to medical devices and comply with IEC 60601-1-4 Medical Electrical Equipment Part 1: General Requirements for Safety, Part 4: Programmable Electrical Medical Systems.
