Intended Use

This device is intended to be used as a central station monitor for the evaluation of the cardiovascular system. It is intended to be used by or on the order of a physician or similarly qualified health care professional. The DS-5800N is intended to be used in hospital environments; ER, ICU, a clinic; or similar settings. This device is intended to be used in those situations where the patient is being monitored by a Fukuda Denshi DS-5000 series bedside patient monitor and remote, central station monitoring is desired. This device is not intended for home use.

Device Story

Microprocessor-based central station monitor; 15-inch color CRT display; touch screen interface. Receives hemodynamic data (ECG, respiration, BP, temperature, SpO2, cardiac output) from Fukuda Denshi 5000 series bedside monitors via Ethernet LAN. Acts as LAN administrator and remote keypad for bedside units; displays data for up to eight patients simultaneously. Used in hospital settings (ICU, CCU, ER) by clinicians to announce and control arrhythmia alarms and review patient data. Does not perform primary signal acquisition or analysis; functions as a secondary display and control interface for bedside monitoring systems. Benefits include centralized patient oversight and remote alarm management.

Clinical Evidence

Bench testing only. Validation included environmental testing per FDA 1993 guidance, electrical safety testing (ANSI/AAMI ES1-1993), and cardiac monitor/alarm testing (ANSI/AAMI EC13-1992). System hazard analysis and simulated environment testing performed to verify design specifications.

Technological Characteristics

Microprocessor-based; 15-inch color CRT; touch screen input. Connectivity via Ethernet twisted pair LAN. Electrical safety compliance: UL 601, CSA 22.2, AAMI standards. Software-controlled; functions as a secondary display/remote keypad for bedside monitors.

Indications for Use

Indicated for patients monitored by Fukuda Denshi DS-5000 series bedside monitors requiring secondary central hemodynamic monitoring in medically supervised healthcare environments. Parameters include ECG, respiration, invasive/non-invasive blood pressure, temperature, pulse oximetry, or cardiac output. Not for home use.

Regulatory Classification

Identification

# Legally Marketed Device:

FUKUDA DENSHI model DS-3300 Patient Monitor; 510(k) number K894628

## Description:

The DS-5800N is a microprocessor based software controlled device. This central station monitor incorporates a 15 inch color CRT display. Up to eight patients can be centrally monitored simultaneously from the ICU, CCU, or other areas of the hospital. Input signals are provided by Fukuda Denshi 5000 series patient monitoring equipment that have been submitted under separate 510(k) filings.

The DS-5800N is a true central station. All data is provided by external sources, Fukuda Denshi 5000 series patient monitoring equipment, for presentation and printout at central. The DS-5800N will act as a remote keypad for the bedside monitors, utilizing its built in touch screen or optional keyboard. The central station will act as the LAN administrator for monitors connected to the Fukuda Denshi patient monitoring LAN and display data from any eight of up to 48 bedside monitors.

The DS-5800N will present alarm information, ECG analysis, and other hemodynamic data acquired and processed by bedside monitors. The DS-5800N does not perform any of these functions. The DS-5800N is used to announce and control arrhythmia alarm information from the bedside.

## Intended Use:

This device is intended to be used as a central station monitor for the evaluation of the cardiovascular system. It is intended to be used by or on the order of a physician or similarly qualified health care professional. The DS-5800N is intended to be used in hospital environments; ER, ICU, a clinic; or similar settings. This device is intended to be used in those situations where the patient is being monitored by a Fukuda Denshi DS-5000 series bedside patient monitor and remote, central station monitoring is desired. This device is not intended for home use.

# Technological Characteristics

The DS-5800N incorporates a microprocessor in a similar manner to the predicate device. Data is acquired from "intelligent" bedside monitors via an Ethernet, twisted pair LAN and presented for display and/or printout. LAN communication is managed by the central station. A touch screen, placed over the CRT offers the operator a means of entering information into the system and controlling the central station.

The technological characteristics of the DS-5800N do not effect the safety or efficacy of the device. Any safety issues that may be raised by a software controlled medical device are the same issues already addressed by the predicate device and are addressed in the systems hazard analysis and in the system validation.

# Testing:

Laboratory testing was conducted to validate and verify the FUKUDA DENSHI DynaScope model DS-5800N Central Station Monitor met all design specifications and was substantially equivalent to the FUKUDA DENSHI model DS-3300's central station function. This testing consisted of all environmental testing identified in the FDA's DCRND November 1993 "Reviewer Guidance Document for Premarket notification Submissions" Draft Guidance Document. ANSI/AAMI ES1-1993, "Safe current limits for electromedical apparatus", and ANSI/AAMI EC13-1992, "Cardiac monitors, heart rate meters, and alarms. Finally, a hazard analysis of the system and its software was performed and testing in a simulated environment was conducted to validate the overall system.

Although the device is neither life supporting nor life sustaining, diagnostic information derived from the use of the device may be critical to the proper management of the patient.

So, the areas of risk for this device are the same as other devices in this class, and are as follows:

- Electrical shock, to the patient or user.
Excessive electrical chassis leakage current can disturb the normal electrophysiology of the heart, and possibly leading to the onset of cardiac arrhythmias.

- Misdiagnosis.
- Inadequate design of the data acquisition and display and printer output circuitry or program can lead to generation of inaccurate diagnostic data. If inaccurate diagnostic data are used in managing the patient, the physician may prescribe a course of treatment that places the patient at risk unnecessarily.
- Inadequate design of the device's software can lead to generation of inaccurate diagnostic data. If inaccurate diagnostic data are used in managing the patient, the physician may prescribe a course of treatment that places the patient at risk unnecessarily.

The design of the DS-5800N has taken into account all the above. The device is designed to meet UL 601, CSA 22.2 and AAMI standards for electrical safety for medical equipment. The device has been tested demonstrate compliance with these standards and to verify that the device does meet all specifications. Review of the test results does confirm that these objectives have been successfully achieved.

## Conclusion:

The conclusions drawn from the laboratory testing of the FUKUDA DENSHI DynaScope model DS-5800N Central Station Monitor demonstrate that the device is as safe, as effective, and performs as well as or better than the legally marketed predicate device, the FUKUDA DENSHI model DS-3300, K894628.
