Acid-Base Disorders

A 56 year old gentleman with chronic obstructive pulmonary disease returns to the intensive care unit following a left pneumonectomy for a squamous cell carcinoma. There is no other past medical history.

Biochemistry and blood gases.

Data sets provided for interpretation included
a)           a combined  resp acidosis and a metabolic alkalosis in a post operative patient,

A 45 year old previously healthy man was transferred to your ICU 5 days ago after a motor vehicle accident with chest and abdominal  injuries. He has been difficult to ventilate on 100% oxygen and 10cm H2O of PEEP.

Scenario:    A 70-year-old female has been transferred  from a  regional  hospital with a  2-week history of profuse  diarrhoea.   She has a Glasgow Coma Score of 15 but looks unwell with a dry tongue.

Arterial  Blood  Gases.  Examples  included  metabolic  acidosis  with  respiratory alkalosis, mixed respiratory and metabolic acidoses, mixed respiratory and metabolic alkaloses, and respiratory acidosis with metabolic alkalosis.

 Arterial Blood Gases including metabolic acidosis with respiratory alkalosis, mixed respiratory and metabolic acidoses, mixed respiratory and metabolic alkaloses, and respiratory acidosis with metabolic alkalosis.

Biochemistry. Examples included cholestasis, raised anion gap metabolic acidosis, hypochloraemic metabolic alkalosis and adrenal insufficiency.

Arterial Blood Gases including respiratory acidosis, mixed respiratory and metabolic acidoses, mixed respiratory and metabolic alkaloses, mixed metabolic acidoses.

Blood gas interpretation.
