Pco2 receptors disease

Metabolism rapidly generates a large quantity of volatile acid (H2CO3) and nonvolatile acid. The metabolism of fats and carbohydrates leads to the formation of a large amount of CO2. The CO2 combines with H2O to form carbonic acid (H2CO3). The lungs normally excrete the volatile fraction through ventilation, and acid accumulation does not occur. A significant alteration in ventilation that affects elimination of CO2 can cause a respiratory acid-base disorder. The PaCO2 is mainta… SpletThe discharge frequency of pulmonary stretch receptors (PSRs) shows an inverse responsiveness to the CO2 partial pressure (PCO2), which is limited to an extremely …
