That there's no PFT machine at office like most pulmonologist have. So you have to go to another hospital because the hospital one is booked until March??very frustrating you should be able to have that test at the office since they have them on a computer also instead of a chamber one. Not patient friendly at all!! now I have to wait to get an appointment for the test in a different facility. Extremely frustrating. I am not happy with such backwards technology in this day and age!! Ridiculous waste of time!! Put a PFT in pulmonologist office so patients can have the test at the time of their appointment!! Wow unbelievable!!
