I Have A Alburtorol Liquid Machine At Home I Get

I have a alburtorol liquid machine at home I get bronchitis quiet often and I have allergies that cause asthma attacks. Currently I have pneumonia so I thought it would help to do a breathing treatment I feel back to normal now but for about 30 minutes after doing a breathing treatment my heart rate was fast and very hardly pounding was this for the breathing treatment or the pneumonia? and do I need to stay off the breathing treatments?
