The Hawksley random-zero sphygmomanometer (random-zero) has been used widely in epidemiological observation studies. This study compares blood pressure measurements using the random-zero with measurements using an automated oscillometric device and suggests a correction of the automated oscillometric measurements to enable comparisons of blood pressure levels over time. The northern Sweden ...

Renal sympathetic nerve activity (RSNA) has been measured in anesthetized mice. However, anesthesia and acute surgical preparation cause poor cardiovascular stability and unphysiological blood pressures. This compromised physiological state confounds proper interpretation of experimental results considering the inseparable link between cardiovascular status and autonomic nervous tone. We, therefore, developed a ...
