If you are not currently certified to provide IV solutions, I strongly suggest you don't. Even if you had previous military training in administering IV fluids, the legal system frowns on "non-certified" people providing this type of intervention. In addition, if usually is difficult to obtain IV solutions and equipment without medical control authorization.
In New York state, an ALS certified provider or paramedic can administer an IV, nothing lower.
You may not agree, but that's how it is.
