Warnings and Cautions General Warnings Proper use of this device depends on the careful reading of all instructions and labels that come with or on the system. Inaccurate measurements may be caused by incorrect application or use. The amplifier is classified as an IP0 – ordinary degree of protection against ingress of water according to IEC 529. The computer used with a Brain Monitor amplifier must either be approved by XLTEK and supplied as part of an IEC 601 approved system, or it must be approved to IEC 950 or similar and kept outside of the patient environment (that is, the area within 1.5 meters of the patient laterally and within 2.5 meters of the floor in the area occupied by the patient). To ensure the validity of signals, do not operate the device near any sources of electromagnetic interference. Turn off system power before cleaning. Prevent detergent solution or cold sterilization agents from seeping into the electronics of the system. Be careful around all connectors and edges. Do not use abrasive agents. XLTEK systems are not AP or APG rated. Device accessories may include several kinds of disposable, sterile needle electrodes. These needles are labeled as STERILE, and the method of sterilization is documented on the packaging. These electrodes should not be used if the sterile packaging has been tampered with. The sale, distribution, or use of this device is restricted to, by, or on order of a physician. Printers and/or peripherals used with XLTEK devices should be marked and approved for use in their appropriate medical environment in accordance with the regulations of the country in which they are used. Do not attempt to connect any third-party devices to the patient breakout box except those approved by XLTEK. The Brain Monitor is not designed to work with, nor shall it be used with, defibrillators or electrocautery devices. The Brain Monitor could be damaged when used with these devices. When the Brain Monitor headbox is used in an end-use system, the system shall be evaluated using IEC 60601-1-1.
13
XLTEK Brain Monitor Amplifier
User & Service Manual
Equipment used in the patient environment shall be IEC 601-1 approved. Equipment used outside the patient environment shall be at least approved to IEC 950 standard.
Electrical Warnings and Cautions XLTEK systems are intended for connection to a properly grounded electrical outlet only. ELECTRICAL SHOCK HAZARD: Do NOT turn on the system power until all cables have been connected, verified and visually inspected for any damage. Failure to inspect the cables may result in electrocution. ELECTRICAL SHOCK HAZARD: Do NOT connect electrode inputs to earth ground. The patient breakout box contains warning symbols reminding you that the connections are intended for isolated patient connections only. Connecting to an earth ground might result in electrocution. ELECTRICAL SHOCK HAZARD: Do NOT service the system. Refer servicing to qualified personnel only.
Patient Environment Warnings and Cautions NOTE: The patient environment is defined as the area within 1.5 meters of the patient laterally and within 2.5 meters of the floor in the area occupied by the patient.
Connect all patient electrodes to fully electrically isolated devices only. Connecting patient electrodes to any other device or external outlet may result in personal injury. The patient breakout box accepts only touch-proof style electrode inputs. Do NOT attempt to use any other style of patient electrode input. The patient event switch attached to the Brain Monitor base unit is NOT intended for critical patient-safety-related incidents. Patient connections are NOT intended for direct cardiac contact.

XLTEK Brain Monitor Amplifier
Masimo Pulse Oximeter Warnings The Masimo SET pulse oximeter is to be operated by qualified personnel only. This manual, accessory directions for use, all precautionary information, and specifications should be read before use. A pulse oximeter is intended for diagnostic purposes and should NOT be used as an apnea monitor. A pulse oximeter should be considered an early warning device. As a trend towards patient deoxygenation is indicated, blood samples should be analyzed by a laboratory co-oximeter to completely understand the patient’s condition. Significant levels of dysfunctional hemoglobins (HbCO or MetHb) may cause inaccurate measurements. Intravascular dyes such as indocyanine green or methylene blue may cause inaccurate measurements. Excessive illumination may cause inaccurate measurements or loss of pulse signal. Excessive patient movement may cause inaccurate measurements. Venous pulsations may cause inaccurate measurements. The board may be used during defibrillation, but the readings may be inaccurate for a short time. Carboxyhemoglobin may erroneously increase readings. The level of increase is approximately equal to the amount of carboxyhemoglobin present. Dyes, or any substance containing dyes that change usual arterial pigmentation, may cause erroneous readings. Loss of pulse signal can occur when the patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia. Loss of pulse signal can occur when there is arterial occlusion proximal to the sensor. Loss of pulse signal can occur when the patient is in cardiac arrest or is in shock. Tissue damage can occur due to incorrect placement of sensor. Do not immerse the sensor in water, solvents, or cleaning solutions. Do not sterilize the sensor by irradiation, steam, or ethylene oxide.
15
XLTEK Brain Monitor Amplifier
User & Service Manual
Do not immerse patient cables in water, solvents, or cleaning solutions (the patient cable connectors are not waterproof). Do not sterilize patient cables by irradiation, steam, or ethylene oxide.
Masimo Pulse Oximeter Sensor Warnings Before use, carefully read the LNOP sensor directions for use. Use only Masimo oximetry sensors for SpO2 measurements. Other oxygen transducers (sensors) may cause improper pulse oximeter performance. Tissue damage can be caused by incorrect application or use of an LNOP sensor; for example, by wrapping the sensor too tightly. Inspect the sensor site as directed in the sensor directions for use to ensure skin integrity and correct positioning and adhesion of the sensor. Do not use Masimo oximetry sensors during MRI scanning as this could potentially cause burns. Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line may cause inaccurate measurements. Loss of pulse signal can occur when the sensor is too tight. Do not use damaged LNOP sensors. Do not use an LNOP sensor with exposed optical components. Do not immerse the sensor in water, solvents, or cleaning solutions (the sensors and connectors are not waterproof). Do not sterilize by irradiation, steam, or ethylene oxide. See the cleaning instructions in the directions for use for reusable Masimo LNOP sensors. Do not use damaged patient cables.
