Route patient cabling to reduce the possibility of patient entanglement or strangulation. Do not use the monitor to monitor neonates. Do not place the monitor in any position that might cause it to fall on the patient. Do not lift the monitor by the power supply cord or patient connections because disconnection could then result in the monitor dropping on the patient. To ensure patient electrical isolation, connect only to other equipment that provides patient electrical isolation. Do not use extension cords to connect the monitor to electrical outlets. Do not use the monitor during magnetic resonance imaging (MRI) scanning. Induced current could potentially cause burns. The monitor may affect the MRI image, and the MRI unit may affect the accuracy of the monitor’s measurements. Do not use the monitor on more than one patient at a time. Do not connect this monitor to any other equipment or device other than those specified in this manual. Sterilization is not recommended for this monitor, related products, accessories or supplies unless otherwise indicated in the instructions that accompany the accessories and supplies. Electromagnetic interference may cause disruption of performance. Protect the monitor from sources of intense electromagnetic radiation. This device has been designed to provide resistance to electromagnetic interference. However, because of the proliferation of radio-frequency transmitting equipment and other sources of electrical noise in the healthcare and home environments (such as cellular phones, mobile two-way radios, electrical appliances) it is possible that high levels of such interference due to close proximity or strength of a source, may result in disruption of performance of this device. Disruption may be evidenced by erratic readings, cessation of operation or other incorrect functioning. If this occurs, the site of use should be surveyed to determine the source of this disruption, and actions taken to eliminate the source. If assistance is required, contact the Life Care Systems Support Group or your local Analogic representative. If the battery is defective, the Loss-of-Monitoring alarm will fail to sound. Connect the monitor only to a three-wire, grounded, hospital grade receptacle. The three-conductor plug must be inserted into a properly installed three-wire receptacle. If a three-wire receptacle is not available, a qualified electrician must install one in accordance with the governing electrical code.
WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING
2.3
Safety
Neither the Print-on-Alarm nor the Nurse Call initiates when the monitor detects a Loss-of-Monitoring state. If an alarm condition (except those leading to a Loss-of-Monitoring alarm) occurs while the monitor is in the Audio Off state, the only alarm indications are visual displays related to the alarm conditions. Use of accessories, transducers, and cables other than those specified may result in increased emissions and/or decreased immunity of the LIFEGARD I patient monitor. The LIFEGARD I patient monitor should not be used adjacent to or stacked with other equipment. If adjacent or stacked use is necessary, the LIFEGARD I should be observed to verify normal operation in the configuration in which it is used. Incorrect insertion of the rectal probe can cause bowel perforation. The LIFEGARD I monitor, while on a patient and in SpotCheck mode, must never be left unattended. All audible alarms are permanently disabled and the attendant must always check the visual alarm indicators. With each new patient, all probes and sensors must be cleaned in accordance with the instructions of Paragraph 13.5, and Temperature Probe Covers must be changed. Temperature Probe Covers are NOT reusable and must be changed with each new patient.
ECG Safety Information WARNING WARNING
WARNING
Use only Analogic ECG electrodes and leads with the LIFEGARD I monitor. Other ECG cables and leads may cause improper performance and/or provide inadequate protection during defibrillation. When connecting the electrodes or the patient cable, ensure that the connectors never come into contact with other conductive parts, or with earth. In particular, ensure that all of the ECG electrodes are attached to the patient to prevent them from contacting conductive parts or earth. For pacemaker patients, the monitor may continue to count pacemaker rate during cardiac arrest or some arrhythmias. Do not rely entirely upon the monitor’s alarm. Keep pacemaker patients under close surveillance.

2.4
Line isolation monitor transients may resemble actual cardiac waveforms and thus inhibit heart rate alarms. Such transients may be minimized by proper electrode and cable placement, as specified in this manual and the electrodes’ directions for use. ECG cables may be damaged when connected to a patient during defibrillation. Check cables that have been connected to a patient during defibrillation for functionality before using them again. DO NOT:
• Use ECG leads that appear frayed, cracked, or damaged in any way.
• Immerse ECG leads completely in water, solvents, or cleaning solutions because the connectors are not waterproof. Electrodes are single use only. Disposal of electrodes must be in compliance with local and facility regulations. Monitoring with the Pacer Detect feature enabled does not normally affect the monitoring of non-pacemaker patients. However, in some instances, if the patient does not have a pacemaker, it may be desirable to turn the detection function Off so that artifacts in the waveform as not mistaken for a pacemaker signal. Interference from instruments near the patient and electrosurgical unit interference can cause problems with the ECG wave. See the monitor specifications for more information.
NIBP Safety Information WARNING WARNING WARNING WARNING
Use only Analogic recommended blood pressure tubing and cuffs. Using other cuffs or tubing may result in inaccuracies. Do not use the monitor on patients who are linked to heart/lung machines. The monitor may not operate effectively on patients who are experiencing convulsions or tremors. Inaccurate measurements can be caused by: • Incorrect cuff application or use, such as placing the cuff too loosely on the patient, using the incorrect cuff size, or not placing the cuff at the same level as the heart. • Leaky cuff or tubing. • Excessive patient motion.
2-4
WARNING

WARNING WARNING WARNING WARNING
Safety
The monitor displays results of the last blood pressure measurement until another measurement is completed. If a patient’s condition changes during the time interval between measurements, the monitor will not detect the change or indicate an alarm condition. Occasionally, electrical signals at the heart do not produce a peripheral pulse. If a patient’s beat-to-beat pulse amplitude varies significantly (for example, pulsus alternans, atrial fibrillation, rapid-cycling artificial ventilator), blood pressure and pulse rate readings can be erratic and an alternate measuring method should be used for confirmation. A patient’s vital signs may vary dramatically during administration of agents affecting the cardiovascular system, such as those used to raise or lower blood pressure or raise or lower heart rate. As with all automatically inflatable blood pressure devices, continual cuff measurements can cause injury to the patient being monitored. Weigh the advantages of frequent measurement and/or use of STAT mode against the risk of injury. In some case, prolonged cycling of an oscillometric, noninvasive blood pressure monitor cuff has been associated with any or all of the following: ischemia, purpura, or neuropathy. Apply the oscillometric cuff appropriately, according to instructions, and check the cuff site and cuffed extremity regularly when blood pressure is measured at frequent intervals or over extended periods of time. Check the patient’s limb on which the cuff is applied to assure that circulation is not constricted. Constriction of circulation is indicated by discoloration of the extremity. This check should be performed at the clinician’s discretion at regular intervals based on the circumstances of the specific situation. Do not place the cuff on an extremity being used for intravenous infusion or any area where circulation is compromised or has the potential to be compromised. Do not apply the blood pressure cuff to the same extremity as the one to which an SpO2 sensor is attached, since cuff inflation will disrupt SpO2 monitoring and lead to nuisance alarms. Ensure that, during use on patients, heavy objects are not placed on the tubing. Avoid crimping or undue bending, twisting, or entanglement or the tubing. Do not use STAT mode when using the thigh cuff to monitor NIBP. A Loss-ofMonitoring alarm with shutdown of all monitor functions may occur.

SpO2 Safety Information
WARNING WARNING WARNING WARNING
Use only Analogic or Nellcor recommended SpO2 sensors. Other sensors may cause inaccurate readings. Incorrect application or use of an SpO2 sensor may cause tissue damage, for example, if the sensor is wrapped too tightly or if supplemental tape is applied. Inspect the sensor site as directed in the sensor’s directions for use to ensure skin integrity and correct positioning and adhesion of the sensor. DO NOT:
• Use sensors that appear frayed, cracked, or damaged in any way.
• Use a sensor with exposed optical components.
• Immerse sensor completely in water, solvents, or cleaning solutions because the sensor and connectors are not waterproof.
WARNING
• Sterilize sensors by irradiation, steam, or ethylene oxide. Refer to the cleaning instructions in the directions for use for reusable sensors. Inaccurate measurements can be caused by: • Incorrect sensor application or use.
• Significant levels of dysfunctional hemoglobins (such as carboxyhemoglobin or methemoglobin). • Intravascular dyes such as indocyanine green or methylene blue.
• Exposure to excessive illumination, such as surgical lamps (especially ones with a xenon light source), bilirubin lamps, fluorescent lights, infrared heating lamps, or direct sunlight. • Excessive patient movement.
• High-frequency electrosurgical interference and defibrillators. • Venous pulsations.
• Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line. • The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia. • There is arterial occlusion proximal to the sensor.
WARNING
• The patient is in cardiac arrest or is in shock.
Loss of pulse signal can occur in any of the following situations: • The sensor is too tight.
• There is excessive illumination from light sources such as a surgical lamp, a bilirubin lamp, or sunlight.
• The blood pressure cuff is inflated on the same extremity as the one to which an SpO2 sensor is attached. 2-6
WARNING WARNING
WARNING WARNING WARNING
2.6
Safety
Disposal of sensors must be in compliance with local and facility regulations. Loose sensor: If a sensor is too loose, it might compromise the optical alignment or fall off. If it is too tight, for example because the application site is too large or becomes too large due to edema, excessive pressure may be applied. This can result in venous congestion distal from the application site, leading to interstitial edema, hypoxemia and tissue malnutrition. Skin irritations or lacerations may occur as a result of the sensor being attached to one location for too long. Inspect the application site every two to three hours to ensure skin quality and correct optical alignment. If the skin quality changes, move the sensor to another site. Change the application site at least every four hours. Venous Pulsation: Do not apply sensor too tightly as this results in venous pulsation which may severely obstruct circulation and lead to inaccurate measurements. Ambient Temperature: never apply an SpO2 sensor at ambient temperatures from above 98.6°F (37°C) because this can cause severe burns after prolonged application. Extremities to Avoid: Avoid placing the sensor on extremities with an arterial catheter, or intravascular venous infusion line.
Cautions Caution Caution
U. S. Federal law restricts this device to sale or use by or on the order of a physician. The following ports on the LIFEGARD I monitor are sensitive to electrostatic discharge during patient monitoring: • SpO2 • ECG
• Temperature probe • RS-232
Follow these guidelines to reduce electrostatic discharge: • Do not touch the connector pins of the port.
• When connecting and disconnecting cables to the ports, use ESD precautionary measures. Precautionary measures may include the following: - Make sure you are grounded prior to connection. Touch grounded metal. - Wear an ESD grounding strap and an ESD protective garment.
Caution
- Provide ESD training to all users. Users should understand what electrostatic discharge is, how damage can occur, and how to prevent ESD. Use only the supplied AC power cord. If in doubt regarding the integrity of the grounding of the AC power source, you should only operate the monitor from its battery. 2-7

Use only the approved accessories for the LIFEGARD I patient monitor. Other leads, sensors, cuffs, or tubing will not work. Any time you press the Audio Alarm Control button, you should check the resulting state of the audio alarms indicated by the icons in the parameter frames, to ensure that the alarm system is in the expected mode. Do not sterilize any Analogic or Nellcor sensor by irradiation, steam or ethylene oxide. Do not use Oxicliq disposable sensors in a high humidity environment, such as in the presence of fluids, which may contaminate sensor and electrical connections causing unreliable or intermittent measurements. Do not use disposable sensors on patients who have a known allergic reaction to the adhesive. The monitor can only store a total of 99 vital sign measurements. This includes patient records and entries within patient records. If you exceed this limit, the monitor overwrites the oldest record or entry, regardless of the record number. Use only Analogic supplied paper. Using incorrect paper can result in damage to the recorder. Do not immerse the monitor or the optional recorder in liquid or use caustic or abrasive cleaners. Do not spray or pour any liquid on the monitor, the optional recorder, or its accessories. Do not allow any liquid to penetrate connectors or openings in the monitor’s or optional recorder’s chassis. A functional tester cannot be used to assess the accuracy of a pulse oximeter probe or monitor.
