Intended Use

The intended use of the SC 6000/SC 6000P Bedside Monitoring Series is to measure heart rate, respiration rate, invasive pressure, non-invasive pressure, arrhythmia (adult) temperature, arterial oxygen saturation, pulse rate, central apnea, and ST Segment Analysis (adult). The device will produce visual and audible alarms if any of the above parameters vary beyond preset limits and produce timed or alarm recordings.

Device Story

Portable bedside monitor; measures ECG, respiration, invasive/non-invasive pressure, temperature, SpO2, pulse rate, and central apnea. Modification adds software for ST segment analysis; computes deviation from isoelectric point. Inputs: ECG signals (any one of leads I, II, III, V, aVR, aVL, aVF). Processing: 100 samples/sec; 900 msec complex length; 15-second update interval. Output: visual/audible alarms, timed/alarm recordings, and ST deviation values. Used in clinical environments by healthcare professionals. Output informs clinical decision-making regarding cardiac status and potential ischemia. Benefits: enables continuous monitoring of ST segment changes to assist in early detection of transient ischemic events.

Clinical Evidence

No clinical data. Equivalence established via bench testing and compliance with IEEE 1992 'Performance Measurements for Algorithms to Detect Transient Ischemic ST Segment Changes' and 1994 FDA 'ST Segment Monitor Preliminary Guidance'.

Technological Characteristics

Portable bedside monitor; software-based ST segment analysis. Sensing: ECG, pressure, temperature, SpO2. Connectivity: Siemens SIRENET or Infinity (Olympus) network. Algorithm: ST segment deviation computation from isoelectric point. Standards: IEEE 1992, 1994 FDA ST Segment Monitor Guidance. Hardware unchanged from K944350.

Indications for Use

Indicated for adult patients in clinical settings where care is provided by trained healthcare professionals (physicians, nurses, technicians). ST Segment Analysis is indicated based on professional assessment of the patient's medical condition. Not for home use.

Regulatory Classification

Identification

The arrhythmia detector and alarm device monitors an electrocardiogram and is designed to produce a visible or audible signal or alarm when atrial or ventricular arrhythmia, such as premature contraction or ventricular fibrillation, occurs.

Special Controls

*Classification.* Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Arrhythmia Detector and Alarm” will serve as the special control. See § 870.1 for the availability of this guidance document.

# Siemens SC6000/SC6000P Portable Bedside Monitoring Series with ST Segment Analysis

## 3. Device Description:

The SC 6000 / SC 6000P Bedside Monitoring Series Enhanced with ST Segment Analysis is an updated software version of the SC 6000 / SC 6000P Bedside Monitoring Series. The modification adds software to determine the ST Segment of the ECG signal and to compute the deviation of this ST Segment from the isoelectric point (baseline). This is the same algorithm that is used in the Siemens 1481 (T) Digital Telemetry System with ST Segment Analysis Option (K951371). The hardware of the SC 6000 / SC 6000P (510(k) K944350) is unchanged.

The ST Segment Analysis is not active when the SC 6000/SC 6000P is in the neonatal mode.

The modified software (version VC0) is not compatible with all previously sold versions of the monitor. Therefore, a software upgrade will be offered to the owners of units with previous software revisions. No hardware changes are required for the upgrade.

## 4. Intended Use:

The intended use of the SC 6000/SC 6000P Bedside Monitoring Series is to measure heart rate, respiration rate, invasive pressure, non-invasive pressure, arrhythmia (adult) temperature, arterial oxygen saturation, pulse rate, central apnea, and ST Segment Analysis (adult). The device will produce visual and audible alarms if any of the above parameters vary beyond preset limits and produce timed or alarm recordings.

| --- | --- | --- | --- |
| Intended Use | The intended use of this device is to detect a patient’s EKG signals and to transmit this data via radiofrequency to a central monitoring station. At the central monitoring station, cardiac arrhythmias, ST segment deviation values and heart rates are determined. The patient’s pulse rate and arterial oxygen saturation values, heart rate values, ST segment deviation values are displayed and visual and aural alarms and recordings are initiated if these parameters vary beyond preset limits. | The intended use of this device is to measure heart rate, respiration rate, invasive pressure, non-invasive pressure, arrhythmia (adult only), ST Segment Analysis (adult), temperature, arterial oxygen saturation, pulse rate, and (central) apnea. This device will produce visual and audible alarms if any of these parameters vary beyond preset limits and produce timed or alarm recordings. This device will connect to the Siemens SIRENET or Infinity(Olympus) network | The intended use for the ST Segment Analysis is the same for both the SC6000 and the predicate, 1481T.
