arterial lines- veterinary

What's the difference between single and double artieral line transducers?

Single typically consists of a single lumen and are more simpler. Whereas double, have a dual lumen, one connects to the arterial catheter and the other connects to a reference sensor. Out of the two, double is more accurate. Hope this helps 🙂

Yea that makes sense thank you.

Don't suppose you know the answer to this too:
I just need a little help understanding this, which will help me at work, so what's the difference between a curved and straight capnograph connector? I would like to know the difference and know when say a curved one is used, as it would help me to set up theatres for surgical patients.
