110: 297:, and suction tubing. Essentially, the saline source is connected to sterile bronchoscope, as is the specimen collection trap, and then suction tubing is connected to the trap and the suction source. If the bronchoscope is not sterile, saline should initially be used to flush it clean. With the patient under some sort of anesthesia (depending on the rigidity of the scope), the fiber-optic cable is lowered into the correct area of the lower lungs ( 301:), wedged into place, and saline applied. Once the saline is fully applied, then either suction is applied to collect the fluids, or the fluids are collected with a sterile syringe through the irrigation channel. The collection trap is then appropriately labeled and sent off for testing. 304:
Recent literature for the use of endoscopic BAL in therapy uses essentially the same process. A flexible bronchoscope is most commonly used. The physician seeks out areas with excess mucus or other abnormalities, then uses saline and suction to clean it.
