The Pneupac compPAC 200HD ventilator is a self contained portable gas powered automatic gas ventilator intended to provide ventilation to patients who have respiratory ditress or insufficiency. The comPAC 200HD is suitable for emergency and transport use for adult and paediatric patients greater than 20Kg in situations where convential portable ventilators may not be suitable

The compPAC COM 200HD ventilator is primarily gas powered and is housed in an easily carried, chemically hardened housing is designed to accept the long endurance battery that is used to drive a small compressor, which in turn provides the inflating gas, through an 'oscillator', to the casualty. All ambient air for the ventilation of the casualty passes into the system through a fitter (NATO No: 4240-01-361-1319). About '// of the volume is compressed to system uncough in the (cre expansion in an entrainment mixing device, which entrains the other 1/3 by creating a sub-atmospheric pressure It can be operated from a range of power sources Battery! Compressed gass! Mains Electricity (via PS11 power supply/ charger unit) and any d.c. power source, ie: auxiliary aircraft/vehicle electrical source (via CS12 power supply/ charger unit) to provide maximum flexibility of operation in remote areas, in disaster relief. The compPAC COM 200HD ventilator is a robust self-contained portable device comprising of the following standard kit parts - Control Module - Green case variant: Part No 510A2433 - Yellow case variant: Part No 510A2434 - Rubber Boot: Part No 510A2271 - Filter: Part No W194-001 - Patient Valve and Hose assembly: Part No 510A1082 - Oz Auxiliary gas input lead, Schrader probe (BS5682): Part No 510A2600 - Support ramp: Part No 510A2372 - 28 volt open-ended Vehicle Supply lead to compPAC Part No 510A2564 - compPAC C200HD User Manual Part No 504-2055A NUS HD And the following fitted labels - Valance Panel Label. Part No 504-228 - Instrument Panel Label: Part No 504-227 - Supplementary O2 Table Label: Part No 504-224 - Battery fitting and removal instruction Label: Part No 504-223 - Alarm Bezel Label (set of 2): Part No 504-222 The module can be used individually as a robust self-contained portable device powered by a NiCad rechargeable battery specified for fitting inside the unit, which will provide approximately (1) hours continuous ventilation. The module weighs 187 lb with the battery installed. The ventilator has a socket to accept an external 24V d c supply from e g. an aircraft or vehicle electrical circuit. This enables the system to be used for extended periods wherever a 24-28V d.c. supply is available. The power requirement is less than 50 watts. If the Pneupac CS12 (d.c. source only) power supply) battery charger (weight 2.2 lbs) is connected to this socket, simultancous full charging of the internal battery will occar whilst the ventilator is running. If the Pneupac PSI i (inains or d.c. source) power supply / battery charger (weight. 3.86 lb) is connected to this socket, simultaneous trickle charging of internal battery will occur whilst the ventilator is running When not required as a power supply it can be switched, to fast charge the battery whilst it is in situ inside the ventilator. Additionally, specifically for aircraft use, an aeromedical EMC filter/ lead assembly (Part No 525-1015) is featured to protect the aircraft from compPAC emissions. An input gas connector is provided to allow the compPAC ventilator to be connected to a 44 to 87 psig gas supply via a legally registered high pressure regulator (not suppliated with the material battered battered hence not part of this submission) so that it can be operated independently of its its internal battery electrical supply In this way, if oxygen cylinders are available, 100% or 4.5% or allows electrical supply in this way. In usygen cymiders are are This facility also allows connection to air compressor systems. Alternatively, there is a supplementary oxygen intake connector, in paralied with the filter, enabling 21-45% oxygen to be supplied to the casualty, from e g an oxygen cylinder was a legally registered high pressure regulator (not supplied with the compPAC, hence not part of this registeres ), when the ventilator is operating on its compressor. Calibrated controls for frequency and minute volume are provided to set the required ventiation pattern. A fixed pressure relief valve is fifted to limit the peak inspiratory pressure to a maximum of 40 cm HzO and provides a pneumatically operated audible high-pressure alarm (an adjustable pressure relief device will also be available in the fittere as a retro-fittable option). In addition an pressure reach device the alarm sounds if the inflation pressure exceeds 40 cm HzO. Most of the controls and input and output connections are mounted on the from panel, which is deeply shrouded to give maximum protection from chemical "rain". The ventilator module comrol panel has the following features. - Minute Volume Control. This calibrated rotary control knob gives continuous adjustment of the minute volume delivered to the patient over the range 6 to 14 L/min. - Frequency Control, This rotary control knob gives continuous adjussment of frequency over the range 10 to 30 breaths per minute - I:E ratio is nominally constant at 1. i. 8 throughout the range of frequency - Patient Inflation Pressure Manometer, range -10 to +100 cm HpO - Oxygen Concentration Control This two-position rovary control in assessed to the eas-후 100% or 45% inspired oxygen concentration when an oxygen supply is connected to the gas-100% or 43% inspired oxygen concentralion withis systed is disabled internally. In the 45% Oz position the driving gas requirement is reduced by 66% and the balance of the In the 45% U position the driving gas requirement arr which is drawn through the fifter canister - A mechanically operated visual alarm (labelled 'Supply Gas Failure Alam') gives a warning that the supply gas has dropped to a pressure at which the ventilator will no longer be warming that the supply gas nas artipped to a pressure it shows red, with adequate its suces the operating to specificated ( red indicates that the supply should be changed In most cases the shows will begin to oscillate from white to parial red as the supply pressure falls to the lower threshold level. The visual indication will be accompanied by an electronically generated medium priority audible warning. - Electronic aların bezel indicating - High Pressure Indicator Flashes Red LED with audible alarm at set relief pressure and with continuous positive pressure - Normal Cycle Indicator Flashes Green LED every time inflation pressure rises through 10 cm H2O - Low Pressure/ Disconnect Indicator Flashes Yellow LED with audible alarm if pressure does not rise through 10 cm H2O within ten seconds. - Silence button silences audible alarm for 60 seconds.

Additionally, specifically for aircraft use, an aeromedical EMC filter/ lead assembly (Part No: 525-1015) is featured to protect the aircraft from compPAC emissions. When the compleAC is operating its imernal compresson, the incoming air is filtered.
