What is the infusion rate of adenosine during the adenosine infusion protocol?

The infusion rate of adenosine during the adenosine infusion protocol is typically set at 0.14 mg/kg/min. This dosing is used in pharmacologic stress testing, particularly in cardiac imaging to induce hyperemia, increasing blood flow to the myocardium. The rate is carefully determined to achieve effective vasodilation without causing significant side effects or complications.

Adenosine is a naturally occurring nucleoside that plays a crucial role in cardiac function and is used in these protocols due to its rapid onset and short duration of action. Administering at the specified rate allows for optimal imaging results, ensuring that there is sufficient blood flow signal to analyze for any abnormalities.

Understanding the mechanism and applications of adenosine in this context highlights the importance of adhering to the correct dosage regimen for accurate diagnostic outcomes.
