Non Rebreathing Circuit Cat

Oxygen flow rate of non rebreathing circuits.

Non rebreathing circuit cat.

Currently the terminology describes the breathing systems as non rebreathing or rebreathing see figures 1 2 for majority of procedures regardless of variations of teaching practice and geographical location provision of two simple pieces of information can be quite adequate for description of a breathing circuit. Non rebreathing circuit systems require a high fresh gas flow to prevent rebreathing of exhaled gases the removal of co 2 depends on fresh gas flow and a flow rate of 3 times of the patient s minute ventilation this is usually at an oxygen flow rate of 200 250 ml per kg of body weight per minute is recommended. This brief summary of the two most popular anesthesia circuits currently in use is intended as an easy reference to simplify and explain the strengths and advantages of both systems. Cats often show no obvious space can also be used safely in cats 3 kg 6 6 lb.

These circuits do not use a soda lime canister but instead use specially designed circuits and a higher fresh gas flow to remove carbon dioxide. Non rebreathing circuit nrb bain vs rebreathing circle systems. Non rebreathing nrb circuits depend upon high oxygen flow rates to prevent rebreathing of co 2. And can accelerate the rate of change in inhalant concentration in the anesthetic circuit.

If you have active scavenge you may need to use higher flow rates. Rebreathing circuits eg circle systems depend on functional one way valves to ensure gas flow in one direction and co 2 absorbents to prevent rebreathing of co 2. Use nrb circuits for patients less than 3 kg 7 lbs. Oxygen flow rates should be.
