Perform calibration of the volume-measuring device and gas analyzers. Patients should avoid eating a heavy meal 1-2 hours before the test. Patients should wear loose comfortable clothing and athletic shoes. If exercise-induced bronchoconstriction is considered, withhold medications as with the methacholine challenge. ECG electrodes/leads are applied. Adjustment of the seat height on a bicycle ergometer is made to permit near-full leg extension when one pedal is at its lowest position (slight bend at knee). Airtight fitting of a low dead-space mask or mouthpiece/nose clips is applied. Apply and correctly position a blood pressure cuff. A pulse oximeter probe is applied securely. Insertion of an indwelling arterial canula for arterial blood sampling is optional.
