The measurement of oxygen levels in tissue is a difficult task. Polarographic electrodes are not suited for determining the mean tissue gas partial pressures of tissue masses larger than a few cubic mm. The delicacy of electrodes also interferes with their use in clinical situations. A new instrument, the medical mass spectrometer, offers opportunities for a more reliable, consistent measurement of tissue gas levels in vivo. This machine is specifically designed to quantitate gases with molecular weights ranging from 10 to 60 amu (atomic mass units) and to display these gas levels in terms of partial pressures.
