I was reading a paper today about a study on dogs, and it mentioned that the dogs were ventilated with a “Harvard Respirator”. It was pretty easy to find a few pictures on Google Images, but I couldn’t find much other information. Apparently it’s just a veterinary ventilator made by Harvard Apparatus. In case you ever need to know. I thought perhaps it was a particular type of device, like a “Holter Monitor”.
You will find a lot of mentions of Harvard respirators on Google, and they are mostly quotes from scientific papers stating that they used a Harvard respirator. Go figure.
ADDENDUM: The very same paper also mentions the pacing rate they used to stimulate the dog’s heart. They don’t mention the normal heart rate for a (mongrel) dog. I looked it up and found it here. It’s between 60-160 beats/min for average-sized adult dogs. That’s a pretty wide range. I’d like to see a plot of heart rate compared to size in dogs.
