The manufacturer of BT recommends that patients be discharged with a Forced Expiratory Volume (FEV1) of within 80% of the day of pre- BT procedure. However, it is unclear if discharging patients below 80% of the pre-BT procedure would result in more Emergency Room (ER) admissions. This study examines the spirometry results immediately before and after BT procedure and the incidence of ER admissions after being discharged home within 48 h and again within 7 days. Methods: In this prospective study, PFTs were measured pre and post BT procedure. BT procedure consists of 3 separate treatments. The following PFT tests were performed: Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), and Peak Expiratory Flow (PEF). Emergency room admissions and visits were collected after being discharged to monitor procedure effectiveness in all subjects. Results: A total of 22 subjects enrolled in the study and 11 (50%) completed all 3 BT procedures. No significant difference was seen in PFT data from baseline to BT3 (p>0.05). Average post BT FEV1% of pre-BT was (BT1= 97% (n=10), BT2= 87% (n=9), and BT3=78% (n=9). There was no complication or admissions post BT procedure seen in all subjects related to the procedure as their Fev1 was within 80%. In addition, there was no significant correlation between ER admission after BT on subjects who were discharged with an FEV1 of <80% of the day of pre-BT procedure.Conclusions: Our findings from this current preliminary data shows that patients being discharged with an FEV1 value of less than the recommended manufacture value does not result in an increase incidence of ER admission. Larger data are needed to provide more evidence to better determine the ideal FEV1 for discharge. %U
