A 77-yeаr-оld pаtient with а significant histоry оf COPD was admitted for a workup before an elective laparoscopic cholecystectomy who is exhibiting some mild lethargy. The nurse practitioner was asked for advice on perioperative management of the patient's severe lung disease.  On room air, the patient’s ABG was as follows: pH: 7.31; PCO2: 76; PO2: 71; HCO3: 38: BE: 8.8.
