NCT00163852

Brief Summary

Adult cystic fibrosis (CF) patients admitted with an acute infection complicated by acid-base disturbance and decreased ventilation will be studied. They will receive salt replacement to correct the acid-base disturbance and possibly their ventilation. Assessment of symptoms (questionnaire), acid-base and electrolyte status (blood and urine tests) ventilation (overnight oxygen and carbon dioxide monitoring non-invasively) and sleep-wake pattern (actigraphy) will be carried out. Study hypothesis: Acute volume and electrolyte replacement corrects hypochloremic hypovolemic metabolic alkalosis and compensatory hypoventilation/ hypercapnia in acute exacerbations of cystic fibrosis.
