What’s New

The functionality of the Infinity Gamma Series patient monitor has been improved and expanded to include the following new features in software version VF4:

!Support of gas monitoring functions in anesthesia and operating room environments. The Gamma XL can now display

concentrations of CO2, N2O, O2 and of the anesthetic agents halothane, isoflurane, enflurane, sevoflurane, and desflurane. The Gamma XL receives these gas values from a Dräger Scio multigas module. Note: This functionality is only available for the Gamma XL (and not the Gamma). For information about multigas monitoring, see Chapter 14, Multigas.

!Support of network laser printers. Recording requests can be sent from the Infinity Gamma Series monitor via the Infinity network to a network laser printer. For information about recording functions, see Chapter 7, Recordings.

!Improved SpO2 performance during motion artifact. For information about pulse oximetry, see Chapter 12, Pulse Oximetry.

NOTES:

!The Gamma XL monitor with Anesthetic Gas Monitoring requires FDA 510(k) review.

!The Gamma XL monitor with Anesthetic Gas Monitoring is not yet licensed in accordance with the Canadian Medical Devices Regulations.

Infinity Gamma Series Software Release Notes

Software Version VF4

!Wireless network operation requires special configurations of the monitoring network and the MULTIVIEW WORKSTATION (a service function). If you experience problems with wireless network operations, contact your Service personnel.

!When moving and assigning a wireless monitor to a different central station, the original central station may emit a brief network error tone and display an Offline message instead of the message Bed Disconnected.

However, there is no disruption of network monitoring and the Offline message clears as soon as you assign a new bed to the central viewport.

!When you change the units of measure at the bedside and the central station is showing the monitor’s bed view, you must first exit the central bed view, before the change of units appears at the central station.

!For network and card data transfer:

—Occasionally, after a data transfer from an Infinity Delta Series monitor, you may see three or four ST trends instead of the two ST leads monitored by the Infinity Gamma Series monitor.

!For network data transfer only:

—If ST is enabled, the ST data transferred from an Infinity Delta Series monitor (VE0) or from a MULTIVIEW Telemetry System (VE0) is ST lead I and II, regardless of the ST leads selected on the Infinity Gamma Series monitor. Note: Other ST data will be permanently lost.

—After a network transfer of telemetry data to an Infinity Gamma Series monitor, ST trend points may appear two minutes apart.

—The IBP data transferred from an Infinity Delta Series monitor (VE0) to an Infinity Gamma Series monitor is labelled GP1 and GP2.

!NBP parameter values transferred from an Infinity Gamma Series monitor to an Infinity Delta Series monitor will be displayed in the trend graphs rather than in the trend tables of the destination monitor.

!On rare occasions, a docked monitor may reset when entering the Transfer Menu under certain network conditions. The monitor returns to the state prior to the reset within 30 seconds.

!When power-cycling the monitor or admitting a new patient, saved monitoring settings may occasionally return to default settings. Check monitoring settings after these events.

!If the Scio module is unable to measure the concentration of N2O, the monitor may enter the error code *A* (artifact) instead of *F* (failure) into the trend storage.

!Occasionally, the ECG waveform is not displayed in the second waveform

channel, when you assign SpO2 to the first waveform channel. In this case, click on the second waveform channel and select the desired ECG lead again.

!When admitting a patient at the MULTIVIEW WORKSTATION, the monitor does not store the admit date, if it is the current date. In this case, you must enter the admit date via the monitor’s Patient Admit menu.

!When the values of an anesthetic agent exceed the measuring range, the monitor displays +++ in the agent parameter box and cycles two out-of- range error messages, one correctly identifying the agent with out-of- range values, the other showing a previously monitored agent.

Important General Safety Considerations

CAUTION: Read all operating instructions carefully before using the monitor. Specific warnings and cautions are found throughout the User’s Manual where they apply.

CAUTION: These devices are not intended for use in the same room as magnetic resonance equipment.

WARNING: Monitor operation is currently not supported in the following environments: magnetic resonance imaging (MRI), aircraft, ambulance, home or hyperbaric chamber environments.

CAUTION: Use only batteries that are approved by Dräger (contact your local representative). The use of non-approved batteries may damage the device.

NOTE: Dräger recommends replacing any lead-acid battery after 12 months of continued use. For safe disposal of lead-acid and lithium ion batteries, follow your local regulations. To prevent risk of fire or explosion, never dispose of the battery in fire.

Dräger is liable for the safety, reliability and performance of its equipment only if (a) maintenance, repairs, and modifications are carried out by authorized personnel, (b) if components are replaced with Dräger approved spare parts and (c) if the devices are used in accordance with Dräger Operating Instructions.

A full technical description is available upon request from your local Dräger representative.

Electromagnetic Compatibility

The monitor has been designed and tested for compliance with current regulatory standards as to its capacity to limit electromagnetic emissions (EMI), and also as to its ability to block the effects of EMI from external sources.

The monitor complies with the following standards pertaining to EMI emissions and susceptibility: EN55011 and EN60601-1-2.

Page 1-2

Infinity Gamma Series

VF4

Overview

Reducing EMI

To reduce possible problems caused by electromagnetic interference, we recommend the following:

!Use only Dräger-approved accessories.

!Ensure that other products used in areas where patient monitoring and/or life-support is used comply to accepted emissions standards (EN55011).

!Try to maximize the distance between electromedical devices.

!Strictly limit exposure and access to portable radio-frequency sources (e.g., cellular phones and radio transmitters). Be aware that portable phones may periodically transmit even when in standby mode.

!Maintain good cable management. Do not route cables over electrical equipment. Do not intertwine cables.

!Ensure all electrical maintenance is performed by qualified personnel.

Site of Operation

CAUTION: The site of operation for the monitor must meet temperature, humidity, and air pressure requirements. For details, see the product description in Appendix A.

WARNING: Do not operate the monitor in presence of flammable anesthetic mixtures with air, oxygen, or nitrous oxide. Do not use the monitor near devices with microwave or other high frequency emissions that may interfere with the monitor’s operation.

WARNING: If fluids are accidentally spilled on the monitor, it should be removed from service immediately and thoroughly inspected by your Biomed to ensure that there is no compromise in electrical safety.

CAUTION: Place the monitor on a flat and stable surface to prevent it from falling. Do not place the monitor into a cabinet, wall recess or similar enclosure during operation. These units are convection cooled (no fan) and need adequate airflow to dissipate heat.

VF4

Infinity Gamma Series

Page 1-3

Electrical Safety

CAUTION: Operate the monitor and any connected devices only in a clinical environment where the electrical installation is in accordance with local electric codes. The universal AC adapter, CPS, or IDS should be connected to a fully tested, hospital-grade outlet with proper grounding.

WARNING: Dräger devices are not intended for use in areas where there is a danger of explosion. If the devices are used where flammable anesthetic substances are used, the possibility of an explosion cannot be excluded.

If the AC adapter, CPS, or IDS is disconnected, the monitor “Battery charger” light turns off and the unit switches immediately to battery power.

Connections to Peripheral Devices

All peripheral devices and connections to the monitor (except the Infinity network) must comply with IEC 60601-1 requirements.

CAUTION: In the interest of patient safety and equipment performance, Dräger does not authorize the connection of other manufacturers’ equipment not approved by Dräger. It is the user's responsibility to contact Dräger to determine compatibility and warranty status if connections to other manufacturers' equipment are desired.

CAUTION: When connecting peripheral devices to the monitor, make sure that the entire system complies with the following requirement: IEC 60601-1-1: Safety requirements for medical electrical systems.

Overview

Safety, Inspection, and Maintenance

WARNING: Because of the danger of electric shock, never remove the cover of any device while in operation or connected to a power outlet via the AC adapter.

In the interest of safety, regular equipment inspection and maintenance is required. Once a year, check all cables, devices, and accessories for damage, ground resistance, chassis and patient leakage currents, and all alarm functions. Also, ensure that all safety labels are legible. Maintain a record of these safety checks. For additional information, refer to the Service manual.

Leakage current will increase when connecting multiple medical devices to a patient. Ensure the electrical shock classification for each device is suitable for the intended application.

Dräger recommends that safety and functional checks be performed on the monitor at least once each year. The temperature and non-invasive blood pressure circuits of the monitor should be calibrated at least every two years. These checks should be performed by authorized personnel, as described in the appropriate Service manual.

When main or battery power is not available, the monitor stores patient data and settings in an internal battery backed-up SRAM. This internal battery will last approximately 10 years if the monitor is operated from main power or from the lead acid or lithium ion battery.

CAUTION: To preserve the life of the internal battery, always leave the monitor connected to main power (using the AC adapter) when not in use. If the monitor is stored unconnected from line or lead acid/lithium ion battery power, the capacity of the internal battery will be drained in approximately three years.

Electrosurgery and Defibrillation Safety

The monitor is protected against high-frequency interference from electrosurgery units and discharges from defibrillators, as well as against 50and 60-Hertz power line interference.

WARNING: The monitor is not protected against highfrequency interference from diathermy equipment.

CAUTION: During Electrosurgery, observe the following guidelines to minimize ESU interference and provide maximum user and patient safety:

!Use the ESU block to connect ECG cables.

!Keep all transducers and intermediate cables off of earth ground and away from the ESU knife and return wires.

!Use the SpO2 pulse rate instead of the ECG to determine the heart rate.

!Use rectal temperature probe sheaths to cover any internally placed temperature sensors.

!Always use the accessories designed for ESU environments.

!If pacer detection is on, the ESU interference may be detected as pacer spikes displayed on the ECG.

Pacemaker Safety

WARNING: Rate meters may continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely entirely upon rate meter alarms. Keep pacemaker patients under close surveillance.

WARNING: Make sure that pacer detection is turned off for patients without pacemakers, and turned on for patients with pacemakers.

Overview

The monitor Gamma has a 6.5”, the monitor Gamma XL an 8” color display. Both monitors have a rechargeable battery. A universal AC adapter is available for connection to a hospitalgrade outlet.

When used as a stand-alone device, you can connect the following peripheral equipment to the monitor via the monitor’s interface plate:

!An R50 Series recorder for printing alarm data, waveforms, trends, and diagnostic logs.

!A nurse call system for broadcasting life-threatening, serious, and advisory alarms.

!A VGA remote display for viewing monitoring data on a larger screen.

For exporting data to external devices, the monitor provides a fast synchronization output (i.e. for defibrillators) and an RS232 connector (via an interface plate or an Infinity Docking Station/CPS Communication Power Supply).

When operating within the Infinity network, the monitor communicates with other network devices and with the MULTIVIEW WORKSTATION™ (central station), allowing central monitoring of bedside data.

For more information on network operation, refer to the chapter

Network Application.

You can transfer patient data between monitors with the help of a Data Memory PC Card or via the network. For information on data transfer, see the chapter Admission, Transfer, Discharge.
