Summary

Understanding the principles and implications of pressure measurement is vital in anaesthesia. Here, in a similar structure to previous chapters we outline the basic physical principles of pressure, the variety of ways that it can be measured in clinical practice and the relationships with other physical principles. There is then focussed material on blood pressure measurement, through invasive and non-invasive techniques, on resonance and damping in pressure measurement systems, and on the measurement of intracranial pressure. The chapter finishes by discussing cardiac output measurement in clinical practice.
