The spectrophotometric determination of the oxygen saturation of blood.

Spectrophotometric determination of the oxygen saturation of whole blood.

A new approach to the spectrophotometric determination of blood oxygen saturation has been made which is based on the absorption maximum of oxyhemoglobin and the isosbestic point of oxyhemoglobin and hemoglobin. The precision of this new method is comparable to that of the manometric procedure in which the Van Slyke-Neil1 apparatus is employed; there is also good correlation between results obt...

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),...

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 ...

A simple spectrophotometric method for the determination of blood sugar by phenylhydrazine Hydrochlorlde

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 ...
