Endotracheal tubes can be flexible and are constructed from various materials, like polyvinyl chloride (PVC), rubber, or silicone. Although latex tubes aren't widely used, it's vital to let your doctor know that you suffer from a latex allergy. An Endotracheal Tube could contain one or two channels inside the tube called a lumen. Double-lumen tubes are typically used when it is necessary to ventilate the two lung areas simultaneously, for instance, during chest or lung surgeries.
