COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
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.
