Software Packages and Software Options

Software Packages

The Dash patient monitor comes configured with the Basic software package. This package consists of standard-of-care parameters, lethal arrhythmia detection, dose calculations, and features required by clinicians caring for acutely ill patients.

Two additional software packages can be purchased separately or in any combination. These packages provide a variety of features that allow the patient monitor to be configured to best meet the needs of its intended environment.

The Cardiac software package focuses on cardiac conductivity. Its features include full arrhythmia analysis and storage, as well as ST segment trending, storage, and templates. The ability to adjust the ST measurement point is also included in this package.

The Cardiopulmonary software package centers on cardiac and pulmonary hemodynamics. Features include the PA insert and wedge algorithms, the intra-aortic balloon pump algorithm, and the thermodilution cardiac output algorithm, including predefined computation constants for the catheters of major manufacturers. Also included are cardiac and pulmonary calculations.

Software Options

Three software options can be purchased separately or in any combination with the software packages and software options.

The High Resolution CRG Trends option provides storage of up to 100 CRG events, and up to 24 hours of CRG trend data, in addition to the CRG feature set found in the Basic software package.

The 12SL™ ECG analysis program with Gender Specific Criteria and the Acute Cardiac Ischemia–Time Insensitive Predictive Instrument (ACITIPI) analysis option uses recorded ECG data to produce a numerical score which is the predicted probability of acute cardiac ischemia. In addition, the gender-specific criteria improves the detection of acute myocardial infarctions (AMI) in women.

The Unity Network option enables you to view other patients on the network, interface with a central station and other network devices, and perform Combo or Rover Combo monitoring.

Equipment Overview: Ethernet Communication

Ethernet Communication

About Ethernet

The GE Unity Network uses Ethernet for device to device communications. This local area network links all patient monitors, clinical information centers, and other GE equipment throughout the hospital. Depending on the construction of the hospital, thick-net, thinnet, or CAT-5 twisted pair cabling is used. The Dash patient monitor is designed to be used with twisted-pair cabling. Consult GE when trying to interface with either thick-net or thin-net cabling. The real-time GE Unity Network operates at 10 Mbps, half-duplex.

Twisted Pair

Twisted pair is the most popular cabling because it is easy to install and flexible to work with. It uses the star topology with a switch as the hub of the segment. A maximum of 100 meters or 328 feet is the longest length of twisted pair cable allowed. The maximum number of devices on the GE Unity Network is 1,000.

Equipment Overview: Ethernet Communication

Network Terms

Node

Each network device or node is assigned a Media Access Control (MAC) Address number and requires a network connection to interface between the network device and the network.

Media Access Control (MAC) Address

A 48-bit address assigned by the manufacturer to uniquely identify a node of the network. This is also known as the Ethernet address.

Switch

To implement the star topology, each network device is connected to a network switch. The switch passes all network data between each network device in the star segment. Typically, the switch supports 12 to 48 network devices and may be linked to other switches to form larger networks.

Segment

IP Address

Subnet

A network segment is comprised of all devices connected to one or many switches which are in-turn connected together to form a larger network. The boundaries of the segment are defined by networking equipment that regulate the flow of packets into and out of the segment (e.g. routers and switches).

A 32-bit (IPv4) address assigned by the user (either statically or dynamically from a server) to uniquely identify the packets from a device for routing purposes.

A subnet is a logical segment of a larger network that shares a common IP address range as defined by a subnet mask. Proper subnetting can improve the performance and security of a network.

Equipment Overview: Theory Of Operation

Power Supply

The subsystems within the patient monitor operate from a common 9 to 18 V power bus. Due to the wide variety of voltages required by the various subsystems, power is converted locally by each subsystem. This architecture results in an efficient and compact system by reducing the number of conversions required and optimizing the physical size of each converter for the specific application.

When operating on AC mains power, the power bus voltage is 18 V, generated by the offline switching power supply.

No AC mains power switch is provided.

The line voltage range switch must be set to select 115 V or 230 V (90 to 132 VAC or 190 to 264 VAC, respectively).

Data Acquisition System (DAS)

All interfaces to the patient occur through the DAS. The ECG function uses a direct connection to the patient; therefore it is separately isolated from the other functions (except respiration, which shares the ECG patient interface) to substantially reduce coupling of noise and leakage currents to/from other functions. All remaining DAS functions (i.e., pulse oximetry, NBP, invasive pressure, temperature, cardiac output, and

) share a common isolation barrier.

NOTE

The patient monitor supports three SPO2 configurations, Generic Ohmeda SPO2, Masimo SET SPO2, and Nellcor OxiMax SPO2.

Equipment Overview: Theory Of Operation

The DAS block diagram with Nellcor 05 DAS PCB assembly consisting of three sections:

Section Description

ECG/Respiration Separately isolated section includes a 7.3728MHz 68HSC05

Main DAS Separately isolated section includes a 22.1184MHz Motorola

microcontroller, A/D conversion, signal processing hybrids and DC-DC isolation converter.

Non-Isolated circuits

The DAS design includes the Nellcor MP100 Module technology. Nellcor SPO2 is classified as motion-resistant. It uses advanced digital signal processing algorithms to extract very low-level SPO2 signals in the presence of artifact induced noise.

The DAS contains all circuitry necessary to support the MP100 Module. The Nellcor MP100 Module contains:

 All SPO2 front end circuitry, such as the digitally programmable

photodetector signal conditioning, A/D conversion, digitally programmable back-to-back LED IR/RED emitter drive and on-board diagnostic / sensor identification signal processing circuits.

 A digital signal processor (DSP), clock circuitry, and program

memory. The Nellcor SPO2 algorithms executes on the DSP. No external memory interface is provided. The DSP is "reset-able" by the DAS CPU.

 A UART for communication of commands and data.

Includes serial and parallel host interfaces and NBP pump, valves, and over-pressure circuitry.

Parameter Functions of the DAS with Nellcor OxiMax SPO2, four BP Channels and Dinamap SuperSTAT NIBP

Except for the SPO2 parameter and additional 2 IBPs, the DAS with the Nellcor OxiMax SPO2 parameter supports the same parameters as DAS with the GE Ohmeda SPO2 parameter. Refer to 2-19.

Probes and Cable

The DAS is intended for use only with Nellcor digital probes. It is not for use with non-Nellcor probes or with Nellcor R-cal (resistor id) probes. An adapter cable is used to interface the probes to the DAS front panel Nicolay connector.

Processor/Power Management Subsystem

Overview

The main processor/power management PCB contains the electrical hardware to provide data processing and display of patient and monitor configuration data, communication and interface circuitry, and power conversion and battery management functions for the patient monitor.

The high level of integration attained in the design of the processor/ power management PCB is attributed to the use of several highly integrated devices. A complex communications controller, ASIC, and battery management hardware significantly improve the performance and reduce the complexity and cost of the assembly. In addition to the CPU, the main microcontroller contains a six-channel communications processor as well as memory, PC Card, and video controllers. The devices used in the core processing architecture all operate at 3.3 V to minimize power consumption, yet the main processor and ASIC are tolerant of 5 V hardware peripherals.

Main Microcontroller

Equipment Overview: Theory Of Operation

The microcontroller contains two processors:

 a true internal and external 32-bit CPU core, and

 a communications processor module (CPM).

The CPM contains an 8 kilobyte dual port RAM to communicate with the CPU core, and once configured communicates with external devices with minimum CPU intervention. External logic is reduced by the internal memory controllers and a system interface unit which provides a clock synthesizer and timers used in this design. Writer communications is supported by direct memory access and processing performance is

enhanced by 4-kilobyte instruction and data caches.

Equipment Overview: Theory Of Operation

Microprocessor Supervisory Circuit, Microcontroller Internal Watchdog Timer

The microprocessor supervisory circuit provides reliable operation of the main processor board. This circuit monitors the +3.3 V power supply and asserts a 140 mS active low reset pulse when the power supply voltage is below +3.0 V during power-up and power-down conditions. A 3 V, 0.5 A hour lithium battery is used to preserve the contents of two SRAM devices and a real-time clock (RTC) when VCC is below the reset threshold.

System Control Logic

The system ASIC contains all of the system control logic for the processor/power management PCB. Such functions include address decoding, peripheral read and write control strobes, smart battery control logic, display control, multiple I/O ports, and front panel key switch debouncing.

Memory

Eight megabytes of non-volatile memory are provided to support the boot code and expansion memory such as high resolution graphic trends data storage. The boot block is write protected.

Eight megabytes of non-volatile memory are provided to support the main software application code.

Sixty-four megabytes of volatile memory are provided by the synchronous graphics RAM. This memory is used for stack, variable storage, dynamically allocated memory and video data storage.

One megabytes of battery-backed SRAM supports storage of 24 hours of 1-minute resolution patient trends, an error log containing 50 input errors, and 50 output errors and storage for the CPM buffers.

The patient monitor configuration data such as Internet and Ethernet addresses, unit name and bed number are maintained in the 2 kilobytes EEPROM. The serial device resides on the I

C bus.

Equipment Overview: Theory Of Operation

The real-time clock incorporates an on-board quartz crystal. This feature simplifies the design and eliminates adjustments. The time of day on a standalone patient monitor is maintained to an accuracy of 15 seconds in 24 hours to support 24 hour trend data. The RTC device is one of the devices on the I

Audio tones are generated using a tone generator, an audio amplifier, and an 8Ω, 2.5-in. speaker. The tone generator has built in D/A converters and a mixer to generate the dual frequency tones. Frequencies ranging from 150 Hz to 2800 Hz are produced.

The microprocessor contains a video controller that supports real-time and non-real-time waveform drawing, menu drawing, and parameter display.

C bus.

Analog Outputs

Defib Sync

Display brightness is controlled by a 50 kΩ digital potentiometer. The potentiometer is interfaced to the brightness control input of an inverter.

Two analog output channels support ECG and BP. The pace pulse is generated on the main processor board and inserted into the analog out ECG signal. The digital-to-analog conversion for both ECG and blood pressure output signals are performed on the main processing board via a two channel 12-bit serial DAC. Cal data is stored on the processor/ power management PCB.

The QRS complex of ECG data acquired from the DAS generates the marker-out signal. A software selectable pulse width and pulse amplitude is provided in the Boot Loader Menu.

Equipment Overview: Theory Of Operation

Optional Thermal Printer

The thermal printer includes complete control of the print head to print the desired waveforms and text as well as monitor power consumption. The host processor on the main processing board has direct communication via an 8-bit data bus to the processor residing within the thermal recorder.

The +9-18 V power supplied to the writer is heavily filtered to provide the storage capability to smooth power surges and transients caused by abnormal thermal printing. Such printing may occur if the patient monitor is subjected to ESU noise. In addition, a writer current limiting circuit restricts the current to the writer to 2.5 A. If this current limit is exceeded, the circuit faults and requires the current limiting circuit to reset through a microprocessor port.

Optional Alarm Light Indicator

An alarm light indicating two levels of visual alarms resides in the handle of the Dash 3000 patient monitor and in the display bezel of the Dash 4000/5000 patient monitors. Red and yellow alarm lights illuminate by addressing an ASIC output port. The Dash 3000 alarm light interfaces to the processor/power management PCB via the 40-pin writer interface. The Dash 4000/5000 alarm lights interface to the processor/power management PCB via the 100-pin DAS/Display / Keyboard interface.

PC Card

The main processor contains a PC Card controller, which complies with the PCMCIA standard. One 68-pin fully compliant Type II PC Card slot is supported in this design for wireless card.

Peripheral Expansion Interface

A 20-pin peripheral expansion interface is provided to support future use. An active low peripheral present signal may be polled by software to identify when a peripheral is attached to the patient monitor. Asynchronous, AUX, and a switched Ethernet serial communication channels are supported as well as switched +9-18 V and +5 V power.

DAS Communication

The microprocessor communicates with the DAS processor using the second serial communication controller (SCC) of the communication processor module (CPM). This asynchronous communication channel operates at TTL levels and is optically isolated within the DAS.

2000966-363C Dash 3000/4000/5000 Patient Monitor 2-31

Page 50

Equipment Overview: Theory Of Operation

Optional Unity Network Communication

The microprocessor provides an Ethernet controller, which is implemented on SCC1 in order to benefit from the additional buffer descriptors compared to SCC2. Ethernet packets are stored in SRAM buffers and are transmitted and received by the 10BASE-T transceiver. The Ethernet clocks are generated from a 20 MHz crystal oscillator circuit and the transceiver. The transceiver also provides a visual indication in the form of four LEDS to identify packet transmit, receive, collision, and link integrity. The status of received data is indicated by the link integrity signal, which is used by the microprocessor to determine if the patient monitor is connected to the Unity Network.

An isolation transformer provides basic insulation to the twisted pair interface required to meet the ANSI/IEEE 802.3 standard (Ethernet). Isolation is required because during transport the power cord with the ground conductor is not available to provide a path for a fault condition. An 8-pin RJ-45 port containing two isolated, differential pairs is provided to connect the patient monitor to a network hub.

NOTE

Power is not provided in the twisted pair interface as in the attachment user interface (AUI) of other monitoring products.

Ethernet Priority

Async Communication

Ethernet communications are prioritized in the following order.

1. Top priority is the Peripheral Expansion interface.

2. Next priority is the Hardwired Ethernet connection at the back of the patient monitor.

3. Lowest priority is the optional wireless connection.

If none of the above exist, then the patient monitor is a stand-alone monitor.

Asynchronous communication ports comply with the GEMMS AutoPort protocol and are provided through an 8-pin RJ-45 port and the 20-pin peripheral interface described in the next section.

Equipment Overview: Theory Of Operation

Debug Patient Monitor and Diagnostic LEDs

An integrated debugger operating in the debug mode within the main processor provides basic emulator-like features such as modification of register and memory locations and setting of breakpoints. The connector required for this serial communication is a dual row 10-pin header. This connector is located within the patient monitor and is not intended for field service use. Tracing of instructions and logic analysis is provided by an adapter board that connects to a socket installed on the main processor board instead of the microprocessor.

Three diagnostic LEDs located along the front edge of the board are provided for general purpose use and are under software control. The LEDs interface directly to port A of the microprocessor. A flashing green LED indicates normal monitoring operation.

Main DC-DC Converter Section

The main DC-DC converter consists of two independent synchronous rectifier buck regulators with one common controller.

Battery Subsystem

The patient monitor uses a “point of use” power conversion architecture with +9-18 V being the main power distribution bus.

Four voltage outputs are developed on the processor/power management PCB:

 +3.3 V,

 +5 V,

 +12 V, and

 –12 V.

Each one of the four outputs are individually current limit protected against overload and short circuit.

Battery charging and control is accomplished on the processor/power management PCB.

The battery is a smart battery and features an on-pack fuel gauge.

Equipment Overview: Theory Of Operation

Lithium-Ion Battery Power

The patient monitor is designed to operate on battery power during transport or whenever AC power is interrupted. A complete battery management system allows you to obtain maximum battery performance. Audible and visual alarms alert you when loss of power is imminent and on-screen capacity gauges indicate battery charge condition and capacity.

Depending on usage, you can get up to 2.5 hours of run time per battery for new, fully-charged batteries. Monitoring NBP, CO2 and SpO2 drain battery power faster than other parameters. The display technology and brightness, graphing, and connection to a wireless network can also alter battery run times.

NOTE

A BATTERY LOW message at the top of the screen warns you prior to complete loss of battery power. Replace the battery or connect the patient monitor to an AC power source when the message displays.

The Lithium-Ion battery is a rechargeable battery containing LithiumIon cells. Each battery contains an integrated electronic fuel gauge and a safety protection circuit.

Impact of Lithium-Ion Battery Technology on the Battery

The following are key points to know about Lithium-Ion battery technology:

 The battery self-discharges on its own, even when it is not installed

in a patient monitor. This discharge is the result of the Lithium-Ion cells and the bias current required for the integrated electronics.

 The battery self-discharges. The self-discharge rate doubles for every

10°C (18°F) rise in temperature.

 The capacity loss of the battery degrades significantly at higher

temperatures.

 As the battery ages, the full-charge capacity of the battery degrades

and will permanently be lost. As a result, the amount of charge that is stored and available for use is reduced.

How to Improve Battery Performance

Installation Guideline

Position the patient monitor in a location that does not artificially increase the operating temperature of the battery.

 To optimize battery life and performance, choose a location that does

NOT artificially increase the ambient temperature surrounding the patient monitor.

 Do not place the patient monitor near a heat vent or near heat-

generating equipment, such as computer monitors.

 Avoid placing the patient monitor in corners where the airflow may

be restricted.

2-34 Dash 3000/4000/5000 Patient Monitor 2000966-363C

Page 53

Equipment Overview: Theory Of Operation

Charging Guideline

Use the Cadex SMart Two+ charger to charge the battery instead of charging the battery inside the patient monitor.

 The Cadex SMart Two+ charger maintains a lower battery cell

temperature during the charge cycle than the patient monitor. This reduction in temperature will extend the life of the battery.

 The Cadex SMart Two+ charger charges one battery in less than 4

hours and two batteries in less than 8 hours. When two batteries are used, the charger applies half of the charging current to each battery.

Conditioning Guideline

Remove the battery from the patient monitor every six months and condition it using the Cadex SMart Two+ charger. This condition cycle recalibrates the electronic fuel gauge.

Storage Guidelines

Do not purchase more batteries than you will use in one year. The battery does not have an indefinite shelf-life. See “How to Store the

Battery” on page 5-8.

How to Identify Battery Charge Capacity

Battery Capacity Definitions

The following terms are used to define the capacity of the battery:

 Design Capacity — The theoretical capacity of the battery cells when

the battery is new.

 Full Charge Capacity — The actual amount of charge the battery can

store and deliver to the patient monitor.

 Remaining Charge Capacity — The amount of Full Charge Capacity

currently remaining in the battery. This is a percent of Full Charge Capacity.

Identify Battery Charge Capacity Using the Patient Monitor

One new, fully charged battery lasts about 2.5 hours. Two new, fully charged batteries last about 5 hours.

A battery that has 100% Design Capacity and is charged to 100% of this capacity lasts approximately 2.5 hours. However, as the Full Charge Capacity declines, the approximate run time of a fully charged battery will decrease.

Single Battery Run Time: Approximately 2.5 Hours – An icon fully outlined with solid lines and completely filled indicates a new battery, fully charged to its Design Capacity.

Single Battery Run Time: Approximately 2.0 Hours – The dotted portion of the icon outline shows that the battery has lost 20% of its Design Capacity. The solid-outline portion is filled in, showing that the battery is charged to 100% Full Charge Capacity.

Full Charge Capacity

858A

Single Battery Run Time: Approximately 1.0 Hours – The dotted portion of the icon outline shows that the battery has lost 20% of its Design Capacity. The solid-outline portion is half filled in, showing that the battery is charged to only 50% of available capacity.

Full Charge Capacity

859A

50% Available Capacity

Identify Battery Capacity Using the Cadex SMart Two+ Charger

When you select the Target Capacity switch on the charger, the charger compares the battery’s performance to a 60%, 70%, or 80% target capacity set on the battery charger. If the battery fails to meet the target performance, the battery charger will prompt you to condition the battery. If after the condition cycle has been completed, the battery does NOT meet the target performance, then the battery charger will illuminate a “fail” light.

monitor.

 FULL — Fully charged.

 CHARGING — Currently being charged.

 IDLE — Not currently in use or charging.

 TIMES — Defines “time to empty” and “time to full.”

 TIME TO EMPTY: — The time to empty represents an estimate

of how much longer the patient monitor will be able to run with the current monitored parameters. Changing the setup, running NBPs, printing graphs, etc. will likely change the value of the time remaining. This value is only displayed when the patient monitor is powered by battery.

 TIME TO FULL: — The time to full represents an estimate of the

time remaining before this battery is fully charged. Total recharge time for this unit is the sum of both batteries’ time to full.

 FUEL GAUGES — Explains the battery capacity gauges.

The fuel gauge is filled from the left to right proportional with the battery’s charge level. The full rated capacity of a new battery of this type is represented by a dashed outline. The maximum charge level for the battery currently installed is represented by a solid outline. As a battery ages, its maximum charge level becomes a smaller percentage of its Design Capacity. The solid portion represents the current charge level of the battery as a percentage of its maximum Full Charge Capacity.

The speaker is used for audible notification of alarms.

Interfaces

Ethernet

The handle serves multiple purposes in the patient monitor. The modular design enables the user to add adapters for specialized applications.

The Dash 3000 handle houses the optional alarm light. This light is visible for 360° surrounding the patient monitor. The light is intended for applications when the audible notification is not useful or effective, such as noisy environments (e.g., emergency vehicles) or quiet environments (e.g., neonatal care areas). The alarm light indicates two levels of visual alarms:

 Crisis alarms (red LED) and

 Warning alarms (amber LED).

The handle also houses the wireless card antennas required for the optional wireless card subsystem.

The Ethernet RJ-45 port provides a hardware connection to the optional Unity Network. The patient monitor has a built-in transceiver for twisted-pair wire. Basic insulation (1500 VAC) isolates the patient monitor from networked devices.

AUX

The AUX RJ-45 port provides an asynchronous communication connection to devices within the bedside care area. Basic insulation (1500 VAC) isolates the patient monitor from other devices.

Defib Sync

Peripheral Expansion

Equipment Overview: Theory Of Operation

The Defib Sync port provides signals needed to perform synchronized cardioversion with a defibrillator. The Marker Out signal is a pulse with selectable amplitude and width that coincides with the patient’s ECG Rwave. The Marker In signal is returned to the patient monitor by the defibrillator. The Marker In signal causes the patient monitor to insert a defib marker in the displayed ECG waveform.

This port also provides two analog signals: ECG and invasive pressure. The patient monitor provides the top displayed ECG signal with reconstructed pace pulses. You can use this signal to trigger a defibrillator or intra-aortic balloon pump. BP1 produces the pressure signal and is intended for triggering an intra-aortic balloon pump.

Asynchronous communication, Ethernet (shared with the Ethernet RJ45 port), 9-18 V power, 5 V power, and discrete I/O signals are provided in the peripheral expansion interface ports. The expansion port pairs with the AC mains power inlet to supply power to the patient monitor through a peripheral device.

Wireless LAN

Initialization

Initialization begins on a card insertion function call from card services. The card insertion function checks the manufacturer and card ID.

Initialization includes:

 Access Configuration Register - Set through card services to the

manufacturer's recommended value.

 The MAC Address is set to the Dash's MAC address to provide

seamless transition from hardwire to wireless and back.

 SSID - Set to stored value. This ID must be the same between a card

and an access point for them to associate.

Reception

The read task waits on a receive interrupt from the card. When awakened, the packet length is validated and the packet is copied into an ethernet buffer. A transfer function using byte-sized transfers is used to ensure the access time to the card is minimized. The packet length and pointer is returned to the ethernet stream.

2-40 Dash 3000/4000/5000 Patient Monitor 2000966-363C

Page 59

Equipment Overview: Theory Of Operation

Transmission

The write task waits on a transmission packet to be queued. When awakened, the card is checked for association to an access point and for an available transmit buffer. Transmits are discarded if both are not true. The packet is copied into the card and a transmit command is issued to the card. The transmit task waits on a transmit complete interrupt from the card. This ensures a transmit buffer will be ready for the write.

Error Handling

The card does not support partial packets or other receive errors. On a transmit error the buffer will not be resent. Other events like buffer and queue overflows are reported through the error log system.

Association Status

Each association change is reported through the error log system.

Command Queue

Commands are queued if the Wait On Command (WOC) bit indicates the card has not completed the previous command. Commands that must complete are issued through a function call that ensures the command is completed before returning. This function delays between each check of the card to allow other tasks to run and must not be called with interrupts off or from within an interrupt.

Storage and Backup

Program Code Storage

Patient Monitor Settings

Card enable/disable

The patient monitor network task determines which active network media should be used for ethernet communication. The peripheral connector has the highest priority followed by the rear connector then wireless. Interrupts to the wireless card are disabled until an enable wireless call is made by the patient monitor network task. Disabling the card simply turns these interrupts back off. Card events like association changes and receive overflows may be logged when interrupts are enabled, but this provides faster switch over between hardwire and wireless than resetting the card and re-initializing it on an enable.

Executable program code for the main processor, DAS processor, and thermal printer are stored in non-volatile programmable memory. To display the revision of the currently stored code, access the submenu of the main application’s Monitor Setup menu.

The processor/power management PCB stores default patient monitor settings in non-volatile memory. The user must restore the original settings if replacing the board.

Patient Data Storage

Time and Date

Calibration Data

Error Log

Equipment Overview: Theory Of Operation

Static RAM backed up by a lithium battery soldered onto the processor/ power management PCB stores patient data.

A patient monitor on the network maintains time and date for at least five years. Time is accurate to within one second in ten hours. The clock is synchronized with a time master on the optional Unity Network.

Calibration factors for NBP and CO2 are stored in non-volatile memory on the DAS board.

Calibration factors for the analog output signals are stored in nonvolatile memory on the processor/power management PCB.

Input and output errors are retained in static RAM backed up by a lithium battery soldered onto the processor/power management PCB. Contents are retained for at least five years, provided that you exercise caution when you handle the board to prevent inadvertently discharging the battery (e.g. when you ship the board for problem diagnosis).

Optional Thermal Printer

The patient monitor uses the same 50-mm thermal printer module that is used in the PRN 50 stand-alone printer. It prints up to four waveforms at chart speeds ranging from 0.1 to 50 mm/s. The printer software is loaded independently from the patient monitor’s software.

In the patient monitor, the printer module limits its current consumption to stay within its allocated system power budget.

Term Definition

SSID SSID is an acronym for Service Set Identifier.The SSID is a sequence of

numbers and characters that represents the ID, a name, of the wireless network. For the 802.11b wireless Dash to connect wirelessly, the SSID from the wireless network must match the SSID of the 802.11b wireless Dash. A 802.11b wireless Dash has a default SSID of rtGEHClinical.

SECURITY A 802.11b wireless Dash provides three levels of security: NONE, WEP

128 bit, WPA-PSK (TKIP).·

 NONE provides no security to the wireless communication  WEP 128 bit, Wired Equivalency Privacy, provides some level of

security, but it is less secure than WPA-PSK (TKIP).

 WPA-PSK (TKIP), Temporal Key Integrity Protocol, is more secure than

WEP. TKIP has a method to change it's security key for each data connection every second. For the 802.11b wireless Dash, WPA-PSK (TKIP) is recommended.

PASS KEY Pass Key is equivalent to passphrase. This is a sequence of words for the

wireless Dash to connect to a security enabled wireless network, WEP 128 bit or WPA-PSK (TKIP). When WEP 128 bit security is selected, the wireless Dash generates the 26 hex characters for four different keys, displayed in four different rows (1st row represents a key index of one, 2nd row for a key index of two, 3rd row for a key index of three and 4th row for a key index of four). One of these keys needs to match the WEP 128 security setting in the access point for the wireless Dash to communicate properly. When WPA-PSK (TKIP) is selected, the wireless Dash will not generate the 26 hex characters. Pass Key or passphrase needs to match the WPA-PSK (TKIP) setting in the access point in order for it to communicate properly.

KEY INDEX (only required for WEP 128 bit)

When WEP 128 bit security is selected, the wireless Dash and the wireless network need to share a same key index.

How to Charge the Battery

The battery can be charged by one of two methods:

 Outside of a patient monitor by using the Cadex SMart Two+

charger.

 Inside a patient monitor that is connected to an AC power source.

NOTE

To extend the life of the battery, GE recommends that you charge the battery using the external Cadex SMart Two+ charger.

Charging the Battery With a Cadex SMart Two+ Charger

1. Insert the battery into the battery charger. The RUN LED lights.

2. Leave the battery in the battery charger until the READY LED lights.

NOTE

If the FAIL LED lights, remove the battery from the battery charger and reinsert it. This should correct any battery charger time out errors. However, if this does not correct the battery charger time out errors, then the battery is defective and should be replaced.

Charging the Battery Inside a Patient Monitor

NOTE

Non-recommended (incompatible) batteries will NOT charge in the Dash patient monitor.

The battery is charged whenever the patient monitor is connected to an AC power source.

When you store the battery inside of a patient monitor that is connected to an AC power source (a state known as “floating”), the battery will selfdischarge to less than 90% of its Full Charge Capacity after approximately two weeks (depending upon the temperature of the battery). At this time, the patient monitor will automatically recharge the battery to 100% of its Full Charge Capacity.

How to Condition the Battery

The battery can be conditioned by one of two methods:

 Outside of a patient monitor by using the Cadex SMart Two+

charger.

 Inside a patient monitor that is connected to an AC power source.

NOTE

To extend the life of the battery, GE recommends that you condition the battery using the external Cadex SMart Two+ charger.

2. Press the CONDITION button when one of the following conditions occur:

 While the RUN LED light is still flashing.

 While the CONDITION LED is flashing.

3. Remove the battery from the battery charger when the RUN LED lights. This completes the conditioning cycle.

Conditioning the Battery Inside a Patient Monitor

NOTE

Non-recommended (incompatible) batteries will NOT condition in the Dash patient monitor.

WARNING

PATIENT RISK HAZARD — Never condition a battery while the patient monitor is connected to a patient. Serious injury or death could result.

Complete the following steps to manually condition the battery using the patient monitor:

1. Remove all batteries from the patient monitor.

2. Insert one battery into Slot A of the patient monitor.

3. Disconnect the patient monitor from the AC power source.

Maintenance: Battery Maintenance

How to Store the Battery

 Condition the battery before storing it. Conditioning the battery to

100% capacity increases the storage shelf-life of the battery.

 Store the battery outside of the patient monitor at a temperature

between 20°C to 25°C (68°F to 77°F).

 When the battery is stored inside a patient monitor that is

powered by an AC power source, the battery cell temperature increases by 10°C to 15°C (18°F to 27°F) above the room’s ambient temperature. This reduces the life of the battery.

 When the battery is stored inside a patient monitor that is

continuously powered by an AC power source and is not powered by battery on a regular basis, the life of the battery may be less than 12 months. GE recommends that you remove the battery and store it near the patient monitor until it is needed for transport.

 Re-condition a stored battery every six months to increase the

storage shelf-life.

How to Wake Up the Battery

When the battery is stored for a long period of time without being charged, it will eventually lose all of its charge and “fall asleep.” When the battery is “asleep,” none of the LEDs on the battery will illuminate when the battery’s on/off button is pressed. You must “wake up” the battery before you can use it again.

There are two methods to wake up the battery:

 Outside of a patient monitor by using the Cadex SMart Two+

charger.

 Inside a patient monitor that is connected to an AC power source.

Waking Up the Battery With a Cadex SMart Two+ Charger

NOTE

A deep discharged battery will require you to repeat the following steps more than once before the battery will “wake up.”

1. Insert the battery into the battery charger and wait for the RUN LED light to illuminate (approximately three minutes).

2. If the RUN LED light does NOT illuminate, complete the following steps:

a. Remove the battery from the battery charger.

b. Re-insert the battery into the battery charger and let the battery

trickle charge for two to three minutes while the FAIL LED flashes. (If the RUN LED light lights, ignore it.)

c. Watch the battery charger LEDs and immediately remove the

battery from the battery charger when the FAIL LED stops flashing AND remains illuminated, OR when both the RUN and CONDITION LEDs flash.
