Nonlinear H-infinity control is proposed for the regulation of the levels of oxygen and carbon dioxide in the blood of patients undergoing heart surgery and extracorporeal blood circulation. The levels of blood gases are administered through a membrane oxygenator and the control inputs are the ...
Measurements were made of exchange rates of oxygen, carbon dioxide, and krypton-85 with blood at 37.5°C. Gas transfer took place across a 1 mil silicone rubber membrane. The blood was in a rotating disk boundary layer flow, and the controlling resistance to transfer was the concentration boun...
Respiratory diseases, such as chronic obstructive pulmonary disease (COPD — also known as emphysema), asthma, and pneumonia, can impair the lungs’ ability to exchange oxygen and carbon dioxide, leading to lower blood oxygen levels. RELATED: Understanding Your Respiratory Rate 2. Anemia Red blood...

PO2, PCO2 and pH levels in the umbilical and uterine blood of the mare and ewe 1. Foetal and maternal blood gas tensions and pH levels have been investigated in the mare and the ewe during late pregnancy under a number of experimental... RS Comline,S Marian - 《Journal of Physiology》...
Blood-oxygen-level dependent(BOLD) response:measured via functional magnetic resonance imaging (fMRI); changes in local oxygenation of cerebral blood flow can be detected. The method has a high spatial and a low temporal resolution. Because 5-HT affects vasculature itself and causes vasoconstriction,...

In subject area: Biochemistry, Genetics and Molecular Biology Blood oxygen saturation (SpO2/SaO2), a crucial indicator of the respiratory cycle, refers to the percentage of the HbO2 oxygen binding capacity in the blood to the total capacity of Hb that can be bound by oxygen. ...
