The measurement of oxygen tension in tissue
1Department of Physiological Nursing, University of California, San Francisco.
Abstract:
Delivery of oxygen to cells is critical to biochemical and metabolic processes and is particularly important during conditions of illness and recovery. However, accurate measurement of perfusion and tissue oxygen tension, determinants of cellular oxygen supply, has been problematic. Technologic advancements offer promise for the assessment of these significant variables. Instruments utilizing polarographic electrodes have been commonly used for the measurement of tissue oxygen tension. Recently, optical fluorescence has been employed to measure the partial pressure of oxygen. These predominant methods for determining tissue oxygen tension are described and applications for research are discussed.

Guidelines For Measuring Vital Signs
Before taking a patient's vital signs, a nurse would consider and assess the patient's comfort level and ensure appropriate equipment is available.
Assessment of Diffusion and Perfusion
The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this principle...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
