Learn why the Moduflex™ Bain circuit adapter is the best open circuit for your surgeries on small animals.
Today we’ll talk about the Moduflex Bain circuit adapter, its advantages, its operations and its use. We will also talk about the fact that it can be mounted on any type of anesthesia machine and why we should use a Bain circuit adapter.
The Bain circuit adapter is used primarily for animals weighing less than ten kilos. The reason why is that the breathing resistance is much lower on the Bain circuit adaptor than the CO2 absorber. You do not have to breathe against the inhalation and exhalation check valves needed. You breathe against the back pressure caused by the soda lime.
Since the breathing bag is always partially inflated, we’re always ready to bag our patient. All we have to do is depress the Pop-off valve and squeeze the bag. Once we’re finished bagging the patient, we release the valve. We can also turn the valve if we wish to squeeze the bag. To reopen the valve, we have a pressure manometer indicating the pressure in our patient’s lungs contrary to a Jackson Rees or Ayres T Piece.
One of the advantages of the main circuit adapter is that the fresh gas combination of oxygen and anesthetic agent is delivered directly to the patient through the center port on the Bain tube. This is much faster than the CO2 absorber which causes a dilution effect.
Contrary to popular belief, when we’re breathing what a Bain tube, we don’t just inhale through the center tube. We inhale through the center tube and through the outer tube. What we have to do is make sure that the outer tube does not contain any CO2 before inhalation. We do this with higher flows, the higher flow flushes out the CO2 of the circuit before inhalation.
