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 …

Spletstimulation of sensory receptors, inducing transmission of afferent impulses to the respiratory centers (4). If the virus involves the alveoli, it may produce hypoxemia (5). The presence of dyspnea would be no physiological surprise in either situation. Surprise would arise only if sensory afferents or hypoxemia elicited Splethistory of chest disease (chronic bronchitis, emphysema and corpulmonale), thearterial pCO2 on admission was higher than on recovery in 37. In manyinstances the initial levels ofpCO2were 30 to 40 mm. higher than those on recovery. Other factors that may precipitate respiratory failure in patients with chronic chest disease are severe asthma ... servicenow procurement module
