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.
Non rebreathing circuit cat.
If you have active scavenge you may need to use higher flow rates.
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.
Use nrb circuits for patients less than 3 kg 7 lbs.
Non rebreathing circuits are designed to deliver oxygen and anesthetic gases with less resistance to breathing in small patients under 10 lbs 7 kg.
Non rebreathing nrb circuits depend upon high oxygen flow rates to prevent rebreathing of co 2.
Non rebreathing circuit nrb bain vs rebreathing circle systems.
Veterinary anesthesia circuits explained.
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.
Oxygen flow rates should be.
And can accelerate the rate of change in inhalant concentration in the anesthetic circuit.
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.
