Abstract/OtherAbstract:
A new plethysmograph for detecting arterial pulse waves in the rat tail is described. With the objective of indirectly measuring the arterial blood pressure in small animal tails an easy-to-build plethysmographic chamber is presented. Essentially in this apparatus the atmospheric air insulated in the chamber is used as the transmitter of the volume changes caused by the arterial flow. By this methodology details of the pulse wave morphology are clearly visible, including the dicrotic notch. It is demonstrated that his chamber combines simplicity with accuracy.
