The enzyme that catalyze the conversion of carbonic acid into CO2 + H2O and vice Versa?
Carbonic anhydrase
A patient was admitted to the hospital with chronic obstructive pulmonary disease. His PO2 was 55 and PCO2 was 65. A new resident orders 54% oxygen via the ventruri mask. One hour later, after oxygen was placed , the nurse finds patient with no respiration or pulse. She calls for a code blue mad begins car. Explain why the patient stopped breathing.
In people who retain carbon dioxide because of pulmonary disease, arterial PCO2 is chronically elevated and chemoreceptors become unresponsive to the chemical stimulus. In such cases, declining PO2 levels act on the oxygen sensitive peripheral chemoreceptors and provide the principal respiratory stimulus, or so called hypoxia drive. Pure oxygen will stop a persons breathing, because his respiratory stimulus ( low PO2 levels ) would be removed.
