A 2 year old child recently brought from a third world country with PMH of an unrepaired hole in the heart and mild cyanosis is brought in to the ED. The patient fed in the AM, then began to cry and became unconsolable, hyperpneic, and deeply cyanotic. On arrival, the patient has a temp of 37.6, HR 180, RR 60, BP unobtainable, O2 sat 40% on room air.

Which of the following would NOT be given for this condition?
