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.
A pulse oximeter indicates the level of oxygen saturation of the hemoglobin in the blood, referred to as SpO2. The test is usually performed on the index finger, measurements being taken at the capillary level. Results can be used to diagnose poor binding between oxygen and hemoglobin, or other hematological problems.
