following conditions:
• pacer pulse synch output from bedside monitor includes the pacer pulse, however, the
characteristics are outside of the pacemaker pulse rejection capabilities specifications as listed in
table A-5.
• pacer pulse synch output characteristics from bedside monitor cannot be determined (chapter 9)
Note any discrepancies in heart rate (HRavg) with the patient monitor HR and ECG waveform
•
display when interpreting derived parameters such as SV, EDV, RVEF, and associated index
parameters. (chapter 9)
•Do not wrap the main body of the oximetry cable in fabric or place directly on the patient's skin
for long periods of time (>10 min). The surface does get warm (up to 45 °C) and needs to dissipate
heat to maintain its internal temperature level. A software fault will trigger if the internal
temperature exceeds its limits. (chapter 10)
•Before touching Yes to recall oximetry data, confirm that the displayed data matches the current
patient. Recalling incorrect oximetry calibration data and patient demographics will result in
inaccurate measurements. (chapter 10)
•Only use approved HemoSphere advanced monitor accessories, cables and or components that
have been supplied and labeled by Edwards. Using unapproved accessories, cables and or
components may affect patient safety and measurement accuracy. (appendix B)
25

2.3 Cautions
The following are cautions that are used in the HemoSphere advanced monitor operator’s manual. They are
introduced in the manual where relevant to the function or procedure being described.
•Federal (USA) law restricts this device to sale by or on the order of a physician.
•Inspect all accessories and equipment for damage prior to use with the HemoSphere advanced
monitor. Damage may include cracks, scratches, dents, exposed electrical contacts, or any signs that
the housing may be compromised.
•Always grasp the connector, not the cable, when connecting or disconnecting cables. Do not twist
or bend the connectors. Confirm that all sensors and cables are connected correctly and completely
before use. (chapter 3)
•To avoid corruption of data on the HemoSphere advanced monitor, always disconnect the patient
CCO cable and oximetry cable from the monitor before using a defibrillator. (chapter 3)
•Do not expose the HemoSphere advanced monitor to extreme temperatures. Refer to
environmental specifications in appendix A. (chapter 3)
•Do not expose the HemoSphere advanced monitor to dirty or dusty environments. (chapter 3)
•Do not obstruct the HemoSphere advanced monitor ventilation openings. (chapter 3)

26
HemoSphere Advanced Monitor2 Safety and Symbols
•Only properly trained personnel should calibrate the HemoSphere advanced monitor analog ports.
(chapter 6)
•The accuracy of continuous SVR depends upon the quality and accuracy of the MAP and CVP data
transmitted from the external monitors. Since MAP and CVP analog signal quality from the
external monitor cannot be validated by the HemoSphere advanced monitor, actual values and the
values (including all derived parameters) displayed by the HemoSphere advanced monitor may not
be consistent. The accuracy of continuous SVR measurement, therefore, cannot be guaranteed. To
aid in determining the quality of the analog signals, regularly compare the MAP and CVP values
displayed on the external monitor to the values displayed on the physio relationship screen of the
HemoSphere advanced monitor. Refer to the external input device operator’s manual for detailed
information regarding accuracy, calibration, and other variables which may impact the analog
output signal from the external monitor. (chapter 6)
•Use a virus scan on any USB stick before inserting to prevent a virus or malware infection. (chapter
8)
•Restore Defaults replaces all settings with factory defaults. Any settings changes or customizations
will be permanently lost. Do not restore defaults while monitoring a patient. (chapter 8)
•Do not force the module into the slot. Apply even pressure to slide and click the module into place.
(chapter 9)
•Inaccurate cardiac output measurements may be caused by: • Incorrect placement or position of
the catheter • Excessive variations in pulmonary artery blood temperature. Some examples that
cause BT variations include, but are not limited to: * status post cardiopulmonary bypass surgery *
centrally administered cooled or warmed solutions of blood products * use of sequential
compression devices • Clot formation on the thermistor • Anatomical abnormalities (for example,
cardiac shunts) • Excessive patient movement • Electrocautery or electrosurgical unit interference
• Rapid changes in cardiac output (chapter 9)
•Refer to Appendix E to ensure computation constant is the same as specified in the catheter
package insert. If the computation constant differs, enter the desired computation constant
manually. (chapter 9)
•Sudden changes in PA blood temperature, such as those caused by patient movement or bolus drug
administration, may cause an iCO or iCI value to be computed. To avoid falsely triggered curves,
inject as soon as possible after the Inject message appears. (chapter 9)
•Make sure that the oximetry cable is securely stabilized to prevent unnecessary movement of the
attached catheter. (chapter 10)
•The catheter and the calibration cup must be dry for an accurate oximetry in vitro calibration. Flush
the catheter lumen only after the in vitro calibration has been completed. (chapter 10)
•Performing an in vitro calibration after the oximetry catheter has been inserted into the patient will
yield an inaccurate calibration. (chapter 10)
•The SQI signal is sometimes affected by the use of electrosurgical units. Attempt to distance
electrocautery equipment and cables from the HemoSphere advanced monitor and plug the power
cords into separate AC circuits if possible. If signal quality problems persist, call your local Edwards
representative for assistance. (chapter 10)
•Do not disconnect the oximetry cable while calibration or data recall are in process. (chapter 10)
27
HemoSphere Advanced Monitor2 Safety and Symbols
•If the oximetry cable is being transferred from a HemoSphere advanced monitor to another
HemoSphere advanced monitor, check that the patient height, weight, and BSA are correct prior to
beginning monitoring. Re-enter patient data, if necessary. (chapter 10)
•Clean and store the instrument and accessories after each use. (appendix F)
•Do not pour or spray liquid on any portion of the HemoSphere advanced monitor, accessories,
modules, or cables. (appendix F)
•Do not use any disinfecting solution other than the types specified. (appendix F)
•DO NOT: Allow any liquid to come in contact with the power connector Allow any liquid to
penetrate connectors or openings in the monitor case or modules If any liquid does come in contact
with any of the above mentioned items, DO NOT attempt to operate the monitor. Disconnect
power immediately and call your Biomedical Department or local Edwards representative.
(appendix F)
•Conduct periodic inspections of all cables for defects. Do not coil cables tightly when storing.
(appendix F)
•Do not steam, radiate, or EO sterilize the HemoSphere oximetry cable. Do not immerse the
HemoSphere oximetry cable. (appendix F)
•If any electrolytic solution, for example Ringer’s lactate solution, is introduced into the cable
connectors while they are connected to the monitor, and the monitor is turned on, the excitation
voltage can cause electrolytic corrosion and rapid degradation of the electrical contacts. (appendix
F)
•Do not immerse any cable connectors in detergent, isopropyl alcohol or glutaraldehyde. (appendix
F)
•Do not use a hot air gun to dry cable connectors. (appendix F)
•Recycle or dispose of the lithium-ion battery in accordance to all federal, state, and local laws.
(appendix F)
