Pulmonary Status

Contents | Prev | Next


It is important to ask about asthma, COPD, emphysema, smoking, restrictive lung disease, recent pneumonia or URI. If indicated, a preoperative CXR, pulmonary function tests or arterial blood gas should be done prior to surgery. Cessation of smoking is controversial due to the fact that it may take 4 to 6 weeks for the lungs to return to their pre-smoking state.
If a patient has reactive airway disease (asthma, COPD), it is important to do elective surgery while their disease process is not active. If they have a current URI, elective surgery should be delayed since an upper respiratory infection can trigger bronchospasm. Consider a regional anesthetic technique in emergent cases, if possible.
