The Induction Chamber Evacuation makes the press!

Coming October 2018:
See Chapter 8 of
Veterinary Anesthetic Monitoring and Equipment. A Wiley publication; publisher of award-winning journals, encyclopedias, books, and online products and services.
In chapter 8 the author talks about how Induction chambers are well known to be a large source of waste anesthetic gas exposure. She also indicates when animals like cats are rabbits are anesthetized in induction chambers, the exposure to animal handlers is great. Furthermore; traditional use of induction chambers are regarded as stressful for the animal.
The Induction Chamber Evacuation System is mentioned in this chapter because the system has been shown to be less stressful for animals and safer for staff.
The induction chamber fills faster and more efficiently. The animal loses consciousness faster, reducing the stressful time spent in the excitement stage. Additionally, waste gas is removed from the chamber before opening, making it safer for handlers.
 

Delayed induction time

Using traditional methods of filling an induction chamber while connected to an in-house (active) scavenging system; it can take as long as 8 minutes for the top portion of an induction chamber to reach 3% isoflurane, resulting in a delayed and stressful induction.
