Why is adenosine rapid IV push?
When given as a rapid IV bolus, adenosine slows cardiac conduction particularly affecting conduction through the AV node. In light of this adenosine should be administered by RAPID intravenous bolus so that a significant bolus of adenosine reaches the heart before it is metabolized.Click to see full answer.

When given as a rapid IV bolus, adenosine slows cardiac conduction particularly affecting conduction through the AV node. In light of this adenosine should be administered by RAPID intravenous bolus so that a significant bolus of adenosine reaches the heart before it is metabolized.Click to see full answer. Then, how do you give adenosine IV push?Adenosine should be administered by rapid intravenous (IV) bolus injection into a vein or into an IV line. If given into an IV line it should be injected through as proximally as possible, and followed by a rapid saline flush. If administered through a peripheral vein, a large bore cannula should be used.Also, what does adenosine do to the heart? In terms of its electrical effects in the heart, adenosine decreases heart rate and reduces conduction velocity, especially at the AV node, which can produce atrioventricular block. Beside this, when should you not take adenosine? Patients with irregular heart rates, especially atrial fibrillation, patients with PSVT mimics such as atrial flutter with 2:1 conduction or sinus tachycardia in a dehydrated or stressed patient should never receive adenosine. Adenosine should never be used in wide irregular tachycardias.Do you dilute adenosine?Adenosine can be diluted with normal saline for doses < 0.2ml (600µg). Use 1ml adenosine (3000µg) with 9ml normal saline to make 300µg / ml. Adenosine is administered by direct IV injection over 1-2 seconds followed by a rapid sodium chloride 0.9% flush.
