Blood Pressure Measurement

Suggested Level of Knowledge: Detailed

LOs

BT_SQ 1.6 Describe the methods of measurement applicable to anaesthesia, including clinical utility, complications and sources of error in particular:

· SI units

· Measurement of volumes, flows, and pressures, including transducers.

· Measurement of blood pressure 

· Measurement of cardiac output

· Measurement of temperature

· Oximetry

· Gas analysis, including capnography

· Methods used to measure respiratory function, including:

– Forced expiratory volume

–  Peak expiratory flow rate

–  Vital capacity

–  Flow-volume loops

–  Functional residual capacity and residual volume
