Worrying is natural. It never hurts to be safe.
Chest pain? Sheesh, that could be anything.
I'd call the local ER. There's usually a triage nurse available by phone.
I had incredible pain in the chest where the ribs connected to my sternum for a while after surgery. I still have no idea what it was. Maybe some kind of apparatus to hold my neck in place that placed pressure on my chest, movement of the cervical vertebrae, or something else. Dunno.
The mention of the inhaler concerns me. Asthmatic? Also, your lungs were basically shut down and mechanically ventilated during surgery. Fluid can pool, minor infections can develop, sometimes it can even lead to pneumonia.
I wouldn't panic -- you've made it past the most difficult hurdles already.
Pain, worry, and stress can all raise your blood pressure. Pulse will be slowed by pain meds and such. That all appears typical.
I would visit an ER if there were breathing difficulties.
At the least, make a phone call just to soothe your nerves.
I'm sure you'll be just fine.
