1.5

USER QUALIFICATION The infusion system is intended for use at the direction of or under the supervision of licensed physicians or certified healthcare professionals who are trained in the use of the infuser and the administration of parenteral and enteral fluids and drugs, and whole blood or red blood cell components. Training should emphasize preventing related IV complications, including appropriate precautions to prevent accidental infusion of air. The epidural route can be used to provide anaesthesia or analgesia.

1.6

ARTEFACTS Nonhazardous, low-level electrical potentials are commonly observed when fluids are administered using infusion devices. These potentials are well within accepted safety standards, but may create artefacts on voltage-sensing equipment such as ECG, EMG, and EEG machines. These artefacts vary at a rate that is associated with the infusion rate. If the monitoring machine is not operating correctly or has loose or defective connections to its sensing electrodes, these artefacts may be accentuated so as to simulate actual physiological signals. To determine if the abnormality in the monitoring equipment is caused by the infuser instead of some other source in the environment, set the device so that it is temporarily not delivering fluid. Disappearance of the abnormality indicates that it was probably caused by electronic noise generated by the infuser. Proper setup and maintenance of the monitoring equipment should eliminate the artefact. Refer to the appropriate monitoring system documentation for setup and maintenance instructions.

SECTION 1 INTRODUCTION

INSTRUMENT INSTALLATION PROCEDURE CAUTION: Infusion system damage may occur unless proper care is exercised during product unpacking and installation. CAUTION: Infusion system performance may be degraded by electromagnetic interference (EMI) from devices such as electrosurgical units, cellular phones, and two-way radios. Operation of the infusion system under such conditions should be avoided. Accessory equipment connected to the analog and digital interfaces must be certified according to the respective IEC standards (e.g., IEC 60601-1 for medical equipment). Furthermore, all configurations shall comply with the system standard IEC 60601-1-1. Any person who connects additional equipment to the signal input or output part is configuring a medical system, and is therefore responsible for assuring that the system complies with the requirements of IEC 60601-1-1. If in doubt, contact Hospira. Instrument installation consists of unpacking, inspection, and self test.

1.7.1

UNPACKING Inspect the shipping container as detailed in Section 1.7.2. Use care when unpacking the infusion system. Retain the packing slip and save all packing material in the event it is necessary to return the infuser to the factory. Verify the shipping container contains a copy of the system operating manual.

1.7.2

INSPECTION Inspect the shipping container for damage. Should any damage be found, contact the delivering carrier immediately. CAUTION: Inspect the infuser for evidence of damage. Do not use the device if it appears to be damaged. Should damage be found, contact Hospira Service Centre (see Section 6.1). Inspect the infusion system periodically for signs of defects such as worn accessories, broken connections, or damaged cable assemblies. Also inspect the infuser after repair or during cleaning. Replace any damaged or defective external parts.

1.7.3

SELF TEST CAUTION:

Do not place the infuser in service if the self test fails.
