A patient with a long history of COPD entered the hospital with labored breathing. His room air arterial blood gases were: pH = 7.23, PCO2 = 67 mmHg, HCO3- = 26 mEq/L and PO2 = 40 mmHg.
Another patient with a history of COPD entered the hospital with labored breathing. Her room air arterial blood gases were: pH = 7.39, PCO2 = 67 mmHg, HCO3- = 40 mEq/L and PO2 = 44 mmHg.
A 17 year old diabetic was admitted to the ER with Kussmaul breathing. Her room air arterial blood gases were: pH = 7.02, PCO2 = 24, mmHg, HCO3- = 6 mEq/L and PO2 = 99 mmHg.
A 45 year old man without previous illness entered the coronary care unit with an EKG diagnosis of "posterior wall infarct" and severe chest pain. His room air arterial blood gases were: pH = 7.51, PCO2 = 30 mmHg, HCO3- = 22 mEq/L and PO2 = 64 mmHg.
A 21 year old woman entered the ER with uncontrolled diabetes mellitus. She was hyperventilating. She was given insulin and sometime later an arterial blood sample was drawn yielding: pH = 7.39, PCO2 = 28 mmHg, HCO3- = 15 mEq/L and PO2 = 97 mmHg.
Another patient who had her diabetes mellitus under control came into the ER. A room air blood gas sample gave the results: pH = 7.42, PCO2 = 40 mmHg, HCO3- = 25 mEq/L and PO2 = 98 mmHg.
A 24 year old patient was admitted to the ER complaining of nausea, vomiting and abdominal cramps for the past 48 hrs. He was found to have an intestinal obstruction and was taken to surgery. His room air arterial blood gases were: pH = 7.63, PCO2 = 40 mmHg, HCO3- = 41 mEq/L and PO2 = 95 mmHg.
