Can the dose of adenosine be slowed with the RRI?
Yes, there are two fixed rates on the RRI. Frequently, the appropriate dose of concentrated adenosine is qs’d (added up to) with normal saline to a full syringe as defined above. An example of a typical desired infusion rate is 140 mcg/kg/min as the full dose infuses over 6 minutes at Rate 1. In this example, Rate 2 can be pressed at any time during the infusion to slow the infusion by 29%, which would be 100 mcg/kg/min.
