High Speed Pulsatile Operation of Miniature Oxygen Electrodes selected to enhance spatial resolution, to obtain a faster time response to reveal changes in p0. within the cardiac cycle, and for low electrode O. consumption. Faster time response may provide new physiological information for possible future application in a research or clinical setting.

A New Histochemical Stain for Intracellular Oxygenution suggested to us that this principle might be used to measure intracellular PO.. Such a technique could eliminate the disadvantages encountered with techniques using electrodes, namely tissue damage and alteration of oxygen tensions by consumption of oxygen, providing that the following criteri

Analysis of Gas Transport in Lungless and Gill-Less Salamanders Using Inert Gas Washout Techniquese have become interested in the respiratory problems of a vertebrate animal which has neither lungs nor gills. Consequently all gas exchange occurs across the skin in the absence of a specialized ventilatory mechanism. This situation is found in the members of the amphibian family Plethodontidae (Wi

Measurement of Tissue Gas Levels with a Mass Spectrometeressures 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 .. This machine is specificall

Analysis of Diffusion Limitations on a Catheter Imbedded in Body Tissues had been attended with relatively little success. Recently, however, Folkman and co-workers (1967) demonstrated that a catheter made of Medical Silastic could measure dissolved blood gases .. Unfortunately, the size of the catheter required surgical insertion. Ernst and O’Steen (1970) developed a c

Dual Wavelength Micro-Oximeter of Hamster Whole Blood in Vitrofficulties are related to the small diameters of the vessels, the small, continuously changing volume of blood flowing in them, variations in the state of red cell orientation and suspension during flow, and numerous optical problems. In order to define some of the problems, establish specific relat
