WARNING: Use of CMV with Demand inhibit Facility Because this function has characteristics specific to this range of ventilators it is important that the sections of the operating instructions describing this facility (See "Variants Covered by this Manual" on page 10 and "Summary Statement" on page 1) are read before this version of the paraPAC plus™ ventilator is used so that the operator understands how the ventilator interacts with the patient during spontaneous breathing. WARNING: Direct Proximal Pressure Sensing Ventilators must never be used without the sensing line attached as this will result in a loss of ‘delivered volume’ to the patient. Although there is no net flow in the sensing line it is recommended that the microbio filter is always fitted to ensure that no patient contamination can enter the manometer circuit within the control module. WARNING: Battery for MRI Use To prevent possible risk of projectile injury within a MRI environment, routinely check for magnetic attraction. To avoid projectile risk in a MRI environment, use only the approved MRI conditional battery, Part No: W269-023. Do not attempt to remove the battery from the ventilator (or take a loose battery) in a MRI environment. WARNING: Potential Unsatisfactory Performance with Alternative Ventilator Patient Circuits. Ensure that only approved circuits supplied by Smiths Medical are used with the paraPAC plus™ range of ventilators. Failure to use the approved circuits could result in death or serious injury. To avoid cross contamination please be aware that the patient circuit is a single use device and should be disposed of after each use. WARNING: Provision of Accessories, Ancillaries and Spares for CE marked products The paraPAC plus™ ventilator is manufactured and ‘CE’ marked to the requirements of 93/42/EEC. To ensure that this equipment functions as intended, use only the manufacturer’s authorised spares and accessories. WARNING: Pre-Use Checks To avoid harm to the patient, pre-use checks must be performed before each use (See "Section: 3 - Set-up, Functional Check and Use" on page 33 and "Functional Check" on page 35) WARNING: Functional Check Deviations noted at functional check should be reported immediately to Smiths Medical and the unit must be taken out of service to avoid the risk of death or serious injury. WARNING: Release of Cylinder Pressure To avoid ignition by adiabatic compression, connect the ventilator to the regulator before opening the cylinder valve slowly. Similarly, prior to changing cylinders, turn off the cylinder valve, switching on the ventilator. When the ventilator stops, it is safe to release the pin index yoke. WARNING: Provision of Alternative Means of Ventilation Always ensure that an alternative means of ventilation is available in the event of ventilator failure or malfunction.

18. WARNING: Adequacy of Gas Supply To avoid harm to the patient, ensure that ventilation can be maintained without interruption, keep a constant check on the adequacy of gas supply by observing the gas cylinder contents indicator and the gas failure visual alarm. 19. WARNING: Interpreting of ‘Spontaneous Breath’ Indicator Actuation of the ‘Spontaneous Breath’ indicator only indicates that spontaneous breathing has been detected and that the low-pressure alarm has been reset as a consequence. The operator must still ensure that patient minute ventilation is adequate. 20. WARNING: Heat Moisture Exchanger (HME) filter If a Heat Moisture Exchanger (HME) filter is used and the patient is experiencing breathing difficulties, or there are mechanical ventilation problems, or decreases in gas exchange, always ensure that there are no blockages in the breathing system. If a blockage is found, immediately replace the breathing system or HME filter. To prevent such problems occuring, filters and HME’s should be routinely replaced in accordance with the manufacturer’s instructions. 21. WARNING: Use in Extreme Environments Extreme environments may impair ventilator performance (see Appendix B), operator vigilance is required to monitor the patient. 22. WARNING: Patient Transportation To avoid harm to the patient, inter- or intra-hospital transport should only be undertaken according to established medical practice and under medical supervision. 23. WARNING: Projectile Risk To reduce the risks of potential projectile injury to the user or patient, the normal routine of checking the ventilator system for magnetic attraction should be followed whenever the equipment is taken into an MRI environment to ensure that magnetically attracted parts have not been added to the system inadvertently. 24. WARNING: Use in Contaminated Atmosphere The paraPAC plus™ ventilator models are suitable for use in contaminated and toxic atmospheres subject to certain limitations as described below and these should be clearly understood by those likely to use the equipment in such environments so that it is only used where appropriate. In any situations where the respirable qualities of the immediate environment are suspect, ventilation should only be carried out in the 100% oxygen (no air mix) mode. This ensures that only a minimum of ambient gas can enter the breathing system. 25. WARNING: MRI Use To prevent possible risk of projectile injury within a MRI environment, routinely check for magnetic attraction. When in use in a MRI environment, to prevent injury to the patient, check the pressure manometer to confirm unchanged ventilation. Also, test the highpressure relief/alarm system by temporary circuit disconnection and occlusion of the ventilator outlet connector, both whenever the system is taken into a MRI environment, and every time the patient is positioned within the magnetic field.

General Description The paraPAC plus™ ventilator consists of a control module and a remote patient valve, connected by means of a corrugated hose (See Fig 1). A description of controls and features on the paraPAC plus™ ventilator is given, see Controls and Features on page 15, the number reference against each description corresponds to the number shown in Figures 2.1 and 2.2. The paraPAC plus™ ventilator is a gas powered (use only dry filtered gas), time cycled ventilator which depends solely on the pressure of the supply gas for its operation. The models described in this Manual additionally incorporate an integrated electronic pressure alarm unit to alert the user to certain significant changes that may occur in the patient’s ventilation. Loss of battery power for the alarm is signalled to the user but will have no effect on the ventilation performance of the paraPAC plus™ ventilator, nor affect the mechanically operated alarms and protection systems.

paraPAC plus™ User Manual - 504-2117
CAUTION: To avoid risk of internal corrosion within the device, use only dry, filtered gas. The control module of the paraPAC plus™ ventilator is rugged by virtue of the design of case, internal pneumatics and electronics. The controls are recessed to minimise the possibilities of damage. Calibrated frequency and tidal volume controls are provided to set the required ventilation pattern and these are clearly colour coded to indicate the recommended settings for adults, children and infants. Used in conjunction with the patient pressure manometer, the PEEP control (Model 310 only) is provided to set PEEP between 0 and 20 cm H2O. An air mix control gives a FiO2 option of 0.50 or 1.0. For longer term ventilation the 0.50 FiO2 setting will normally be used and in this setting gas consumption is significantly reduced - by almost 70% - giving greatly extended cylinder duration. On the paraPAC plus™ ventilator, selection can be made between O DEMAND, I CMV & II (Model 310 only). When I CMV is selected, the ventilator cycles at the set frequency but if a spontaneous breath is taken during an exhalation phase then this is taken from an internal demand valve. If breathing is at an adequate level for an adult, cycling will be inhibited as long as this breathing level is maintained. If breathing becomes inadequate, CMV will be restored, synchronised with the last breath. When O DEMAND, is selected, only the internal demand valve is energised by the gas supply. When the patient is connected to the patient valve, any spontaneous breathing effort is satisfied by flow from the demand valve. This provides a very gas efficient method of treating a victim with an unprotected airway where enhanced oxygen [tidal volume dependent see table in Appendix C, page 91] is recommended as the approved therapy. It can also be used to protect a spontaneously breathing patient during rescue from a contaminated atmosphere. The control module is designed to be mounted in a variety of ways as described on page 29. A wide range of attachments and brackets are also available. The paraPAC plus™ ventilator may be driven by oxygen from a compressed gas cylinder or pipeline system.
