The enhanced software (version VA4-1XX) is compatible with previously sold versions of the monitors. A retrofit will be offered to the owners of units with previous software versions.

Following are descriptions of the SC 6000 and SC 6000 P systems enhancements covered in this submission:

## Cardiac Arrhythmia Detection Option:

The Siemens SC 6000 & SC 6000 P offer an Optional Cardiac Arrhythmia Detection System that detects, alarms both visually and audibly and generates recordings for ventricular tachycardia (VT) and PVCs/min. Prior to this enhancement the Siemens SC 6000 & SC 6000 P detected, alarmed both visually and audibly and generated recordings for only the cardiac arrhythmias of ventricular fibrillation and asystole.

The Optional Cardiac Arrhythmia Detection System functionality is achieved with a software upgrade.

The Siemens SC 6000 & SC 6000 P Optional Cardiac Arrhythmia Detection System is equivalent to the Cardiac Arrhythmia Detection System of the Siemens SC 9000. The Siemens SC 9000 was granted premarket approval under 510 K file number K946306. The SC 9000's Cardiac Arrhythmia Detection system has been integrated into the SC 6000 & SC 6000 P software (K944350).

To support substantial equivalence to the predicate SC 9000 system the SC 6000 & SC 6000 P Cardiac Arrhythmia Detection system has been tested using the test and results reporting called out in the AAMI (ECAR-1987) "Recommended Practice for Testing and Reporting Performance Results of Ventricular Arrhythmia Detection Algorithms" and the FDA "Guidelines For Submitting Data In Support of Premarket Notification (510(k)) Applications for Arrhythmia Detectors" (1990).

**Enhanced respiration rate tracking during periods of respiration rate slow downs:** When breathing stops, the respiration rate algorithm now updates at a rate equal to the expected respiration rate. This provides an accurate indication of the respiration rate. For example a respiration rate of 15 breaths per minute (bpm) exists prior to the cessation of breathing. The respiration rate will change from 15 to 14 bpm after 4 seconds. Prior to this enhancement the respiration rate would stay at 15 bpm until a new breath was detected or if no breaths occurred drop to 0 bpm after 30 seconds.

**Narrower respiration signal band width:** The bandwidth of the processed and displayed respiration signal is 0.25 to 3.0 Hz. Prior to this enhancement the bandwidth was 0.05 to 7.0 Hz. The 0.05 to 7.0 Hz bandwidth has a slow recovery time for baseline offsets and passes cardiogenic artifact to the respiration rate algorithm. A slow recovery time to baseline offsets can result in missed breath detections and cardiogenic artifact can result in false breath detections.

All the Respiration Rate Algorithm Improvements are achieved with a software upgrade.

For details concerning the Respiration Algorithm Improvements validation testing consult Exhibit R.

## ECG Baseline Recovery Improvement:

The performance of SC 6000 and SC 6000 P’s ECG Baseline Recovery has been improved to center the ECG within 5 seconds after the ECG drifts out of the display range. Prior to this enhancement the ECG was not centered unless it drifted outside of the amplifiers range.

The ECG Baseline Recovery Improvement is achieved with a software upgrade.

For details concerning the ECG Baseline Recovery Improvement validation testing consult Exhibit R.
