I realize this was going on last evening. I hope you're doing OK. Asthma isn't anything to fool around with. You need to get your follow up education and know your "plan" as the previous poster was talking about. In general, your albuterol inhaler is your "rescue" medicine....whenever you start feeling tight, SOB, wheezy. Take 2 puffs, if no relief or minimal relief; it is usually reccomended that you repeat 2 puffs after 20 minutes.(Sometimes protocol states you can repeat a final time 2 puffs, after 20 min.) If still no relief, this is when you need to be getting yourself in to a doc, an urgent care, the ER, wherever. You need a breathing treatment or two. Sometimes, if it has progressed enough, you will be put on steroids. Your heart rate was up due to the albuterol, it also makes you very "shaky"...like you just drank 10 cups of coffee.
If you are having a hard time getting under control, or have a lot of exacerbations they will set you up with a nebulizer for home use.
Anyway, there is a lot more to asthma education, please start learning as much as you can, get a peak flow meter, know your triggers (URI's, dust, pollen, allergies, etc), medications, etc.
