The Walker Art Center is home to an in-depth collection of Oldenburgâs work, ranging from early performance-related objects to large-scale outdoor sculpture to drawings, prints, multiples, and rare studies.
Chemoreceptors detect the levels of carbon dioxide in the blood by monitoring the concentrations of hydrogen ions in the blood. Learning Objective. Describe the role of chemoreceptors in the regulation of breathing. An increase in carbon dioxide concentration leads to a decrease in the pH of blood due to the production of H+ ions from carbonic acid.
Theory and Mechanics of Pulse Oximetry. A. A pulse oximeter uses two sensors and a light source to determine what percentage of oxygen saturation. is in the blood. The device uses the color of the blood to determine the oxygen content of the blood. 1. Each sensor detects for a different color of light. 2. Oxygenated blood is a brighter shade of red than un-oxygenated blood.
