    I have never used low pressure airbags for extrication and never heard of such. We use high pressure for lifting and pushing situations. The low pressure bags are reserved for stabilization situations.

    They are not used much in auto extrication, they are mainly used in heavy truck and ag extrication. Most low pressure systems are owned by heavy wrecker companies, and can be an excellent tool in lifting very heavy and bulky vehicles, although a lot of these companies have gotten away from frequent use of them because today's heavy wrecker are equipped with rotating bombs, synthetic straps and rigging that can do the job so much faster and easier.
    There are some medium pressure bags that are used in auto extrication which may be what you are talking about. These are great for a lot of things other than auto extrication also.

    As Lee indicated low pressure bags come in several sizes but are generally used for extreme lifts.They are also VERY intolerant of sharp objects which limits their use in extrication.A 5 bag system is easily capable of lifting 80.000 # plus at around 5psi. About 20K to get a good starter set.For most outfits a Hi pressure bag set would probably be a better choice. T.C.

    It all depends on the situation. MAny high pressure bags simply do not have the lift required by a semi drive under or other similar situation.
    The pillows also have other uses like a filler in trench rescue senarios.

    air bags are common place for high pressure bags

    air cushions are common name for low pressure cushions, because they are in fact a "cushion".

    low pressure cushions can run from 7 psi to 10 depending on the style or manufacturer

    they are much easier to use for a high lift of say 20" or more on a car.

    You have to keep in mind though that low pressure bags require a greater volume of air. When multiple big cushions are used the y require a significant air source such as a pic of a set up below. Though you may get away with a Scott bottle on a small starter cushion, it would be a joke to try using on a multiple cushion set up.



    bigger cushion sets use a console like pic below


    You also have to respect the fact that it is air in the bags, and they can give you that "mushy" effect while lifting a smaller vehicle such as a car.

    I will dig up some pics of the low pressure bags being used to lift a cab of a truck to free a patient

    I wouldnt use an air bag to stabilize anything, its full of air. Wood, jacks, chains, cranes etc are all stabilization tools, not air bags.

    Two pictures below show low (yellow) and medium (black) pressure cushions being used to stabilize a trench wall and for an overhead lifting operation.
