Doppler and oscillometric mean blood pressure best represent direct blood pressure measurements in anesthetized rhesus macaques (Macaca mulatta).

Background: Indirect blood pressure measurements are often used to guide clinical decisions, but few studies have verified their agreement with direct arterial blood pressure in nonhuman primates. Here, the accuracy and precision of Doppler (DOP) and oscillometric (OS) [systolic (OSsys), mean (OSmean), and diastolic (OSdias)] blood pressure readings were assessed in rhesus macaques.

Methods: DOP and OS were utilized to measure blood pressure values in nine anesthetized rhesus macaques, which were compared to direct measurements via a saphenous arterial catheter.
