Warning
To avoid a fire hazard, keep matches, lighted cigarettes, and all other sources of ignition (e.g., flammable anesthetics and/or heaters) away from the Ventilator System and oxygen hoses.
Do not use oxygen hoses that are worn, frayed, or contaminated by combustible materials such as grease or oils. (Textiles, oils, and other combustibles are easily ignited and burn with great intensity in air enriched with oxygen.)
In case of fire or a burning smell, immediately disconnect the ventilator from the oxygen supply and electrical power source.
Warning
Patients on life-support equipment should be appropriately monitored by competent medical personnel and suitable monitoring devices.

Warranty
The 700 Series Ventilator System is warranted against defects in material and workmanship in accordance with Nellcor Puritan Bennett Medical Equipment W arranty for a period of one year from the time of sale. T o ensure the validity of the warranty, be sure to keep a maintenance record.
Year of manufacture
The 700 Series Ventilator System’s year of manufacture is indicated by the fifth and sixth digits of the serial number located at the lower edge of the ventilator front panel.
Manufacturer
Nellcor Puritan Bennett Ireland Ltd. Mervue, Galway Ireland
Electromagnetic susceptibility
The 700 Series Ventilator System complies with the requirements of IEC 601-1-2 (EMC Collateral Standard), including the E-field susceptibility requirements at a level of 10 volts per meter, at frequencies from 26 MHz to 1 GHz, and the ESD requirements of this standard. However, even at this level of device immunity, certain transmitting devices (cellular phones, walkie-talkies, cordless phones, paging transmitters, etc.) emit radio frequencies that could interrupt ventilator operation if located in a range too close to the ventilator. It is difficult to determine when the field strength of these devices becomes excessive. Practitioners should be aware that radio frequency emissions are additive, and that the ventilator must be located a sufficient distance from transmitting devices to avoid in terruption. Do not operate the ventilator in a magnetic resonance imaging (M RI) environment. Section 7 describes possible ventilator alarms and what to do if they occur. Consult with your institution’s biomedical engineering department in case of interrupted ventilator operation, and before relocating any life support equipment.

.......................................................................................
This section provides introductory information on the Nellcor Puritan Bennett 700 Series Ventilator System. It contains a description of the ventilator, including specifications, required tools and test equipmen t , schedule of maintenance, and controls and indicators.
1.1 How to use this manual
The 700 Series Ventilator System Service Manual is intended to be used in conjunction with the 700 Series Ventilator System Operator’s Manual. Both parts are needed for field repair of the ventilator.
In several cases, however, similar information is contained in both manuals:
Refer to the “Maintenance” appendix of the Operator’s Manual for operator maintenance of filters and the patient system. Refer to the “Service and repair” section of the Service Manual for maintenance activities performed by the service technician.
Refer to the “Self-tests” section of the Operator’s Manual or this manual for instructions on running short self-test (SST) and extended self-test (EST). This manual also provides EST troubleshooting information for the qualified service technician.
1.2 Safety
The “Part numbers” appendix of the Operator’s Manual contains ordering information for patient system parts. Refer to the “Parts list” section of the Service Manual for complete part ordering information.
Warning
To p revent personal injury or death, do not attempt an y ventilator service while a patient or other person is connected to the ventilator.
To prevent disease transmission, use personal protective equipment when handling contaminated bacterial filters or other patient accessories. Use Cavicide to kill bloodborne pathogens, as required.
Ventilator maintenance may involve exposure to hazardous materials, equipment, and conditions such as: possible electrical shock; pressurized gas; transmittable diseases; and fire, which could result from an oxygen-enriched en vironment and easily ignitable material. Before servicing the 70 0 Series Ventilator System, be awar e of possible hazards and necessary precautions to be taken.
Familiarize yourself with the warnings and caut ions on the ventilator labels and in related publicatio n s, includin g th is manual. Also familiarize yourself
with any warnings and cautions associated with the service equip ment and materials being used, as well as those posted in the facility where the ventilator is serviced.

1 General information
.......................................................................................
Use any applicable personal protective equipment and adhere to the applicable warnings and cautions.
Be aware of the safet y standards and consi de ra t ions specific to your situation. Safety standards may vary with international, federal, state, and local
regulatory agencies. When in doubt, consult material safety data sheets; environmental, health, and safety professionals; and regulatory affairs specialists. In addition, many facilities and institutions may have their own special safety considerations.
Be sure the ventilator passes the performance verification (Section 5) before it is retur n e d to operation after being serviced. The performance verification
ensures the product’s safety in addition to its functional integrity.
1.3 General description
The 700 Series Ventilato r System (including the 740 and 760 Ventilators) provides respiratory support for a wide range of pediatric to adult patients for a wide variety of clinical conditions. The ventilator’s mixing technique allows it to ventilate critically ill patients at adjustable oxygen concentrations without the need for a blender, compressor, or hospital-grade wall air.
The 700 Series Ventilator System can be mains or battery powered. Each ventilator includes two microcontrollers: one for breath delivery (which controls ventilation), and one for the user interface (which monitors ventilator and patient data). Each microcontroller verifies that the other is functioning properly. Using two independent microcontrollers in this fashion prevents a single fault from causing a simultaneous failure of controlling and monitoring functions.
The 700 Series Ventilator System supplies mandatory or spontaneous breaths with a piston-based pneumatic system. Mandatory breaths can be volume con trol ventilat ion (VCV, available on 740 and 760 Ventilators) or pressure control ventilation (PCV, available on the 760 Ventilator only). VCV delivers breaths to the patient at a preset tidal volume, peak flow, waveform, and oxygen concentration at a minimum respiratory rate. PCV delivers breaths to the pa tient at a pr eset insp iratory pressure, I:E ratio or inspiratory time, rise time factor (how quickly inspiratory pressure rises to achieve the set inspiratory pressure), and oxygen concentration at a minimum respiratory rate. A spontaneous breath allows the patient inspiratory flows of up to 300 L/min, with or without pressure support ventilation (PSV). On the 760 V e ntilator , you can set the rise time f actor a nd exha lation flow sensit ivit y (t hat is, the point a t which the ventilator cycles from inspiration to exhalation) in PSV.
The ventilator begins apnea ventilation if no patient- or operator-initiated breath is delivered within the operator-selected apnea interval. Apnea ventilation is available in all modes (for ventilators equipped with software Rev. J or later). On the 740 Ventilator, only VCV breaths are available in apnea ventilation. On the 760 Ventilator, VCV or PCV breaths are available in apnea ventilation.
