Respiratory acidosis developing in emphysematous patients from impaired pulmonary ventilation is well known.2-4 Patients with normal lungs undergoing surgery have been observed to develop carbon dioxide retention from the failure of the anesthetist to maintain adequate ventilation.1,6 In the immediate postoperative period, it is not unexpected that instances of serious respiratory acidosis are found. This may be an exacerbation of a chronic acidosis in an emphysematous patient, or it may be acute, from interference with ventilation by events related to the operation.
