Asthma or bronchitis? Symptoms are coughing with no mucus, difficulty breathing, chest tightness, gasping for air. Took albuteral and it works.

Cough ; ..... Hello. This sounds like typical asthma. See your doctor for further treatment and evaluation.
They're the same. Asthma and bronchitis are points along a spectrum of bronchospastic diseases, blending seamless along the path. There is no sharp demarcation between them. The fact that you respond well to albuterol means that you're closer to the "asthma" end of the spectrum.
