Ktf! What a great find.......Ohtu=02! Very subtle! I will search to see if I can find a site that will explain the different methods of pulmonary toileting. Being a 45 year veteran nurse helps a lot too! The congestion is the worse ever that is why some of the methods in conjunction with inhalers and nebulizers help and coughing continually is exhausting. The Ohtuvayre, jfsherley, is delivered via jet nebulizer twice a day. It is specifically intended to reduce secretions in a different manner (system) than Dupixent . The studies showed favorable results and was approved in June of July by the FDA. Marketing and availability through specialty pharmacies since September.
