The study aimed to demonstrate a possible beneficial role of Nitric oxide (NO) in large artery district. Pulse wave was recorded in the carotid artery of anesthetized SD rats and AIx was measured in the rat.

Arterial pulse wave recording in small rodents utilized the Micro Pressure Measurement System and transducers available from BIOPAC, and developed by Samba Sensors AB, Goteborg, Sweden.

Samba products are not available as of Nov. 2012 – contact a BIOPAC rep to discuss other solutions for micro pressure measurement.
