WebThe International Societyon Oxygen Transport to Tissue (ISOTT) was founded in 1973 to facilitate the exchange of scientific information among those interested in any aspect of the transport and/or utilization of oxygen in tissues.

WebPathology [ edit] The partial pressure of carbon dioxide, along with the pH, can be used to differentiate between metabolic acidosis, metabolic alkalosis, respiratory acidosis, and respiratory alkalosis . Hypoventilation exists when the ratio of carbon dioxide production to alveolar ventilation increases above normal values – greater than 45mmHg. Web28 aug. 2024 · Hyperventilation is breathing that is deeper and more rapid than normal. It causes a decrease in the amount of a gas in the blood (called carbon dioxide, or CO2). This decrease may make you feel lightheaded, have a rapid heartbeat, and be short of breath. What happens when PCO2 increases?
