Flowbac is a single-use disposable breathing filter used in anesthesia and critical care breathing circuits. It's used to keep a barrier between the patient and the breathing equipment when air or other anesthetic gas mixtures are delivered to the patient. The filter is normally connected at the "machine side", one filter on the inspiration side and another filter on the expiration side. Flowbac is available either bulk packed and non sterile or packed and sterile.
