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
