The following chart was supplied by the manufacturer of the "M" cylinders. It refers only to the Medical "M" cylinder, and should be used as a reference only to gauge the contents of the oxygen system consisting of a single Medical "M" cylinder at different pressures.

Reference Only Sys. Pressure Capacity Capacity Sys. Pressure Capacity Capacity

(liters) 2216 122.57 3471 ║ 1200 65.57 1857 2200 121.69 3446 ║ 1100 59.99 1699 2100 116.11 3288 ║ 1000 54.43 1541 2000 110.53 3130 ║ 900 48.89 1385 1900 104.96 2972 ║ 800 43.39 1229 1800 99.31 2812 ║ 700 37.92 1074 1700 93.66 2652 ║ 600 32.48 920 1600 88.08 2494 ║ 500 27.09 767 1500 82.43 2334 ║ 400 21.73 615 1400 76.78 2174 ║ 300 16.42 465 1300 71.18 2016 ║ 200 11.15 316

In all cases, pressure at the outlet is regulated to approximately 55 PSI. LifePort Inc. uses a two-stage regulator. The first stage brings bottle pressure down to a manageable level (around 375 PSI). The second stage regulates to approximately 60 PSI. Care should be taken not to let the bottle pressure run down too low, however, as low pressure can cause fluctuation at the outlet. Never let the bottle pressure go below 400 PSIG if at all possible. Oxygen will still be delivered but flows may vary at the outlet.

Figure 7.0.2 Oxygen Drawer-Sub Components 7.2 Air System Compressed air is provided through an air pump. The air pump is an oil-less, non-lube piston pump and cylinder. The pump is rated at 120 PSI (with pressure relief at 100 PSI), but LifePort sets it to 60 PSI. The reason for this is that most medical devices are calibrated to work at 50 PSI, and once air begins to be drawn from the system the pressure will drop. In-house testing has shown a setting of 60 PSI produces the maximum output from the pump when the pressure reduces to 50 PSI. This pressure is adjustable should you need more or less for the optimum performance of your medical devices (see below). The air regulator should only be adjusted by a trained medical technician and tested with the actual medical device with which the air system will be used. In the event of a momentary interruption of the pump, an accumulator provides even pressure and flow at the outlets. An accumulator is simply a cylinder that contains a volume of air (in this case 26 cu. inch as the standard) at the pumps maximum pressure. Also plumbed into the air system is an air - water separator / regulator. This allows the delivery pressure of the compressed air system to be adjusted if need be. It also removes moisture from the air prior to delivery. The separators come standard with a pulse drain, which will automatically expel any moisture so that manual draining is

LifePort, Inc. EMS Litter Operators Manual CSR-737-00 Rev IR not necessary. As air is drawn into the system and the pressure fluctuates it causes the drain to retreat from its seat, allowing any accumulated moisture to escape.

LifePort, Inc. EMS Litter Operators Manual CSR-737-00 Rev IR There is also a 5-micron filter attached inside of this unit. The filter will further purify the air prior to delivery to the patient. Compressed air delivery is provided though the outlets on the side of the base unit. Outlet types vary depending on customer requirements. All types are checked and will not dispense air until the connection is made with the mating connector. Likewise, each system is keyed so as not to allow connection to the wrong gas source, such as attaching a compressed air line into the oxygen source. Below are the approximate flow rates of the compressed air systems with one pump. These figures are minimums based on LifePort testing and should be taken as reference figures only, as there are many variables that affect the actual flow of air (length of plumbing lines, number of fittings, atmospheric conditions, etc.). LifePort, Inc. recommends that tests be conducted using the operator’s particular brand of ventilator to determine the maximum setting achievable using the compressed air system before actual use on a patient. PRESS. (PSIG) FLOW (CFM) FLOW (LPM) PRESS. (PSIG) FLOW (CFM) FLOW (LPM)

0 .8 21 60 .4 10 10 .7 18 70 .3 9 20 .6 16 80 .3 8 30 .5 14 90 .3 7 40 .5 13 100 .2 7 50 .4 11

As you can see the pressure greatly affects the flow, therefore the allowable pressure differential between the oxygen and compressed air system (when using a customer supplied blending device) also becomes a factor. Again, testing with your ventilator at different settings to determine the maximum allowable settings is strongly advised.

7.3 Vacuum System There are two vacuum pumps is installed for medical suction. LifePort’s vacuum pump is a diaphragm pump capable of producing between 20" and 22" -Hg of suction (with free flow). The pump is plumbed directly to the suction outlets on the face panel and arch and is intended to be hooked to a vacuum canister. The same types of gas outlets are available as in the compressed air system. Pumps used in LifePort, Inc. equipment are tested at the factory for flow. Our baseline acceptable output is 20 lpm at 5" -Hg. 7.4 Control and Outlet Panel All the systems are accessed and controlled on the control and outlet panel on the aft end of the base unit.

LifePort, Inc. EMS Litter Operators Manual CSR-737-00 Rev IR 8.0 Installation and Removal of Base Unit(s) The following information applies to the Base Unit only -- the AeroSled is installed at the time of flight. After the initial installation has been performed and signed off, additional removals and installations require only a log entry, and weight and balance change by a properly rated technician. If the aircraft is to be operated in more than one configuration (i.e. aeromedical and corporate or cargo, etc.), this will facilitate changes from configuration-to-configuration by maintaining a weight and balance form for each configuration used. 8.1 Installation Instructions for Base Unit(s) The following instructions are for installing and/or removing a Base Unit that had, initially, been installed per the STC data, and is reinstalled, unchanged, in the same location.

Step 1: Remove seats as required. Step 2: Install 6 brownline nuts (PN 900-1034) per unit into the aircraft brownline tracks.

LifePort, Inc. EMS Litter Operators Manual CSR-737-00 Rev IR 10.0 Maintenance The Instructions for Continued Airworthiness includes the required inspection schedule. The only regular maintenance requirements concern the oxygen bottles and the filters. The oxygen bottle must be hydrostatically tested (ref CFR 173.34) at time intervals not to exceed those specified by DOT. For the 3AL aluminum pressure vessels, the time limit is 5 years. LifePort, Inc. requires that the oxygen regulator be replaced with a new unit at the time of the oxygen bottle hydrostatic check. The regulator is not considered a repairable item. The air - water separator has a filter that should be replaced when discolored. There is an additional filter on the side of the air pump for the intake. This filter is a white fiber pad about 1” in diameter. Replace filter when dirty, retain with safety wire or a cotter pin.

LifePort, Inc. EMS Litter Operators Manual CSR-737-00 Rev IR 11.0 System Care To disinfect the medical system, isopropyl alcohol or a 5% bleach and water mix is recommended. Commercially available products to disinfect may also be used as long as they don’t contain other chemicals. ****************************************************CAUTION***************************************************

NEVER USE AN OIL OR CHEMICAL BASED CLEANER. The front panels of the base unit are made of Lexan plastic. Interaction with some chemicals causes “crazing”, or radical cracking. Oil or oil-based products should never be used in the vicinity of oxygen. The mattress has a stain resistant coating on it. Use soap and water or a very mild detergent for cleaning. Chemical based or abrasive cleaners can remove the stain resistant properties of the material and therefore should not be used. Moving parts, such as the back rest hinge, knee lift hinges, bed arch hinge and bed release pins, should be periodically lubricated for optimum performance. Any dry type lubricant (such as graphite or silicon lubricant) can be used. When the system is removed from the aircraft it should be stored so that it is protected from the elements, such as rain, direct sunlight, sand and salt spray. Extreme temperatures should be avoided. System components should be kept free of oil and grease due to the oxygen. The bed and cargo pallet have plastic covers on he feet that can pick up debris. These should only be set on a clean surface. All open connectors and gas fittings should be capped.

LifePort, Inc. EMS Litter Operators Manual CSR-737-00 Rev IR 12.0 Oxygen Servicing The oxygen system is serviced through a fill port located in the large drawer in the 4’ base unit. The location of the fill port is clearly marked.

WARNING! Oil, grease or other lubricants, in contact with high-pressure oxygen, can create an extreme fire hazard and any such contact must be avoided. Do NOT permit smoking or open flame of any kind near airplane or system while work is performed on the oxygen system.

1. Use breathing oxygen conforming to MIL-O-27210 or other specification approved by the medical personnel for

medical use. 2. Check oxygen system high pressure gauge. 3. Check that oxygen bottle valve is on. 4. Do not charge system if fittings or filler valve are corroded, contaminated or damaged. Clean filler valve, if

contaminated, with stabilized trichloroethylene and let air-dry. Do not use solvent. 5. If cylinder is completely empty, do not charge until system has been purged. To purge, charge system to

approximately 500 psi and vent. 6. Connect filler valve to external filling equipment. 7. Fill bottle per instructions associated with the filling apparatus, whether a large vessel or cascade system. 8. Fill to the pressure in the following table based on the ambient temperature.
