2 year old sleeping HR 130s

My 2 year old has a cold (stuffy nose, no fever no other real symptoms). I put the owlet sock on because they have a history of croup. Their heart rate is in the 130s while sleeping. Is that normal? Usually it’s around 90 so I’m a bit freaked out.

They have been eating and drinking a bit so I don’t think they’re dehydrated.
