Hi Stacia,

Thanks for the feedback! I checked in with our Equipment Specialist, and while we aren't 100% sure where this one came from (we've had it for a very long time) she recommended a very similar product here:

It also looks like you can also find a few different varieties on Amazon by searching for "pail tipper". I hope those recommendations can help your team!

Does the carbon dioxide gauge have influence on the frequency in which you change the soda lime in the Snyder? We are trying to establish a formal protocol in regards to changing the soda lime and we are currently changing it when the CO2 level is over 1200. When large dogs are in there we can change it as frequently as every 2 hours but smaller dogs can go as long as 8 hours.

Hello Jessica, thank you for the great question. Our protocol here at Dove Lewis is to change the baralyme granules in our oxygen snyders every 6 hours if being consistently used throughout the day, or sooner if needed. If our Snyders are not being used frequently (just a few patients a day), we will still change the baralyme granules every 12 hours no matter what because they are not fully encased in a container like on our anesthesia machines. Instead, they are kept on trays that we pull out when the granules need to be swapped out. Also, our Snyders are not big enough to put large dogs in them, so we usually use nasal prong oxygen tubing for our larger patients and have them resting in kennels and/or runs. I hope this helps answer your questions.

Take care,
Bobbie Lucas
