Blood pressure measurement

Contributor(s): Anna Meredith, Paul Flecknell, David Perpinan

Introduction

  • Blood pressure measurement is important in evaluating cardiac function and monitoring anesthesia Anesthesia: intra- and post-operative care in rabbits.
  • Arterial blood pressure is the product of cardiac output, vascular tone and blood volume, and is defined by the equation: Blood pressure = cardiac output x systemic vascular resistance.
  • Thus, blood pressure is raised either by increasing cardiac output or systemic vascular resistance, and lowered by a fall in cardiac output or vascular resistance.
  • Overall, large differences are obtained between blood pressures measured in the carotid and auricular artery (direct measurement), and those obtained by Doppler or oscillometric technique (indirect measurement). Due to this large variation, blood pressure measurement in rabbits is still not as useful as it is in other species such as dogs and cats.
