High flows open circuit ( NON REBREATHING )
To perform this type of ventilation it is necessary to take off the soda
lime canister from valves group.
•
The breathing gas concentration is similar to the fresh gas ones.
•
There is a high consumption of fresh gas
•
The temperature and humidity of breathing gas are low. The high flow
ventilation is recommended only for pre-anaesthesia and awakening or for brief
surgeries.
•
There is not CO 2 accumulation in the patient circuit.
Required supervision: normal
Semi-closed circuit ( REBREATHING )
•
The fresh gas flow in the patient circuit is lower than the ones breathed by the
patient; therefore the fresh gas concentration of the breathed gas is different
than the ones of the fresh gas, related to the BREATHED GAS / FRESH GAS
ratio
•
There is a medium consumption of soda lime.
•
There is a medium consumption of fresh gas.
•
The temperature and humidity of the fresh gas are acceptable for a long surgery
situation.

Required supervision: pay attention to the gas concentration
monitoring (O
