Abstract: A system for delivering or withdrawing a fluid to or from the body of a patient in a manner that permits delivery to be controlled based upon feedback from the patient, the system including a syringe assembly providing a syringe operably coupled to one or more sensors adapted to determine one or more corresponding parameters associated with fluid delivery and/or withdrawal, and a monitor adapted to be communicably associated with the one or more sensors of the syringe assembly, and optionally with other sensors or inputs providing additional parameters as well, the monitor comprising one or more read out mechanisms either directly or indirectly corresponding to the one or more fluid delivery/withdrawal parameters, and optionally with one or more of the additional parameters as well.

Abstract: A method for treating a patient comprising: (a) injecting into the bloodstream of a patient is breathing a gas mixture having greater than 25% oxygen an aqueous solution comprising: 0.1 to 0.8 M Mg++ and having an osmolarlity less than about 1500 mOSm/l; and (b) increasing the rate of injection at least until the patient feels a sensation of warmth is described.
