Since there are no living dinosaurs, there is no way that we can answer, except to guess.
The average respiratory rate for adults is 10 to 14 breaths per minute. Taking this average, the number of breaths in an hour would be 600 to 840 per hour.
Adults average between 18,000 - 30,000 per day.
Let's see: I take about 12 breaths a minute. There are 60 minutes in an hour. That means I take 720 breaths an hour. That means I take about 11,520 breaths during the 16 hours when I am awake. When I fall asleep my breathing slows down. At 10 breaths a minute that is 600 breaths an hour. that will be 4,800 breaths when I am asleep. 11,520+4,800= Whoops my adding machine just disappeared from the screen.
Well , the average person takes 28,880 breaths a day, so 28,880 times 365 is a grand total of 10,541,200 breaths a year.
Everyone is different. Some people breath deep and therefore take fewer breaths in one hour. People who breath shallow will take more breaths. It also depends on what kind of shape you are in.
About 60 breaths per minute. Or about 1 per second.

It could be an inanimate object, in which case, the answer is 0.
19 breaths per minute * 5 minutes = 95 breaths per 5 minutes
About 190,500 breaths a week.
