Nitrogen Analysis

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

· Gas analysis, including capnography

 

I thought I would do a special post on Nitrogen, because it is a gas we use in most of our anaesthetics, but rarely monitor. It obviously is possible to measure it in real time, because nitrogen washout one of the methods used in the determination of FRC.

T/F Nitrogen can be measured using a paramagnetic analyser

T/F Nitrogen can be measured using a infra-red analyser

T/F Nitrogen can be measured using a gas discharge tube

T/F Nitrogen can be measured using a rapid response Clark electrode

T/F Nitrogen can be only be measured using a mass spectrometer
