at least one irrigation source 110 the pressure supply line 140 may provide any pressure desired by the user up to a maximum available pressure and may use air or any specific gas to provide the increase or modification in pressure in at least the irrigation source 110 the irrigation source 110 may the form of an iv bag for example or may be or include any vessel used to hold irrigation fluid the pressure supply line 140 may be connected to the lower end of the irrigation source 110 such that pressurization of the irrigation source 110 is accomplished by the gas being delivered through the pressure supply line 140 whereupon the gas passes through a vent tube 502 see fig7 and into a pocket of gas above the irrigation fluid such a connection to the lower end of the irrigation source 110 may be made through an iv spike 610 for example in this way for example the pressure supply line may be suitable for use with any size irrigation source additionally and alternatively the pressure supply line 140 may terminate at the top or highest point within the irrigation source to allow for the dispensing of the pressurized gas with little to no interaction with the body of the on fluid within the irrigation source 110 this form of delivery may decrease or eliminate the interaction of the delivered gas with the irrigation fluid and may thus further decrease turbidity associated with the introduction of a pressurized gas delivery of irrigation fluid may occur through a second line 150 which may.
