Measurement of arterial and capillary blood oxygen tension

    An oxygen electrode system, supplied as an attachment to the Radiometer Astrup micro equipment for blood pH determination (AME I), has been investigated. Determination of blood oxygen tension using this electrode system has been compared with tension measurements using an established Bishop type oxygen electrode and satisfactory agreement was found. The storage of blood for routine estimation of oxygen tension has been investigated. Capillary blood oxygen tension has been measured and compared with that of simultaneously taken arterial blood samples.
