Pulmonary function tests were done and as I mentioned, the doctor asked me to continue to Trelegy. O2 levels are not below 92 and are always in the mid-90s. He basically said that the Trelegy or Breztri were the best options. I just want to try something else because I cannot see any improvement. I am wondering if a different type of inhaler might perhaps be worth trying. I have attached a clear copy of the ER diagnosis.
