Caffeine is a brochodilator, though a weak one and improves PFT’s for short periods of time. I thought I remembered that from nursing days and did a very quick look. This study was done for asthma patients.

Caffeine alone may be an effective bronchodilator when used on a short-term basis;
however, a relatively large regular dosing of caffeine (eg, one to three cups of strong
coffee every six hours or less) would be required for significant, sustained bronchodilation,
since caffeine is a relatively weak and short-acting bronchodilator.

Caffeine is a drug that is very similar to theophylline. Theophylline is a bronchodilator drug
that is taken to open up the airways in the lungs and therefore relieve the symptoms of asthma,
such as wheezing, coughing and breathlessness.

Caffeine also helps lower respiratory muscle fatigue and can temporarily improve lung function

5 mg/kg body weight of caffeine achieved a peak bronchodilator effect within 2 h and lasted for six hours.
