When performing procedures on patients with potentially infectious airborne diseases, practition-ers should wear a personal respirator or a close-fitting surgical mask, especially if the testing in-duces coughing. Practitioners should always wash their hands between testing patients and after contact with testing equipment. Although it is unnecessary to routinely clean the interior surfaces of the testing instruments between patients, the mouthpiece, nose clips, tubing, and any parts of the instrument that come into direct contact with a patient should be disposed, sterilized, or dis-infected between patients.
