Spectrophotometric determination of the oxygen saturation of whole blood.

Spectrophotometric studies. XVI. Determination of the oxygen saturation of blood by a simplified technique, applicable to standard equipment.

The metabolism, as measured by oxygen consumption, of organs in situ is being increasingly investigated by the vascular catheterization technique (see Drabkin (3) for pertinent literature). The oxygen consumption is derived from the arteriovenous difference in the oxygen saturation or percentage of oxyhemoglobin (4) of blood entering and leaving the tissue. Such work has pointed to the need of ...

Spectrophotometric determination of blood oxygen.

Gasometric methods for estimating blood oxygen are time-consuming. This consideration often limits the number of observations which can be made in the course of experiments requiring oxygen determinations. In many cases it is an arteriovenous difference which is particularly desired, as in the measurement of cardiac output by the Fick principle, or the estimation of oxygen consumption by human ...

A modification of the spectrophotometric determination of carbon monoxide in blood enabling direct determination of per cent hemoglobin saturation.

BECAUSE OF VARIATION in hemoglobin concentration in normal bloods with age and sex (1), the per cent carbon monoxide saturation of hemoglobin represents a more accurate toxicity index than the volume per cent of carbon monoxide. In 2 of the most common methods of carbon monoxide determination in blood, the gasometric method of Van Slyke (2, 3, 4) and the spectrophotometric method of Harper (5),...

The spectrophotometric determination of the oxygen saturation of blood.

ORDY AND DRABKIN (1) have described a simplified spectrophotometric procedure for the determination of oxygen saturation of whole hemolyzed blood. The described method of sampling by use of tonometers, although technically precise, is somewhat inconvenient for routine clinical use. In a note appended to the article, Marsh described a simpler modification. He collects the samples in oiled, hepar...
