      Monitoring arterial pressure is an important aspect of providing clinical care to the anaesthetized and critically ill patient. Because auto-regulation of major organ blood flow may be impaired in these patients, maintenance of an adequate organ perfusion pressure is essential, particularly to vital areas such as the brain, heart and kidneys. It is imperative that those patients experiencing or at risk of cardiovascular instability and inadequate organ perfusion are selected for direct continuous monitoring with beat-to-beat variation. Other patients still requiring routine cardiovascular monitoring may be adequately monitored with intermittent indirect blood pressure measurement. This article outlines the different types of arterial monitoring seen in the intensive care and operating theatre environment.
