Bain Blocks (Armstrong Arms) |
Dr. Bob Stein |
| Noncircle systems like the stock Bain system are associated
with a number of drawbacks. These drawbacks include the awkward delivery
of positive pressure ventilation (PPV) including an uncertainty as to the
actual pressures delivered during PPV, and difficulties collecting waste
gases.
Adding a Bain Block (Armstrong Arm) rectifies these concerns. This ~$300 USD investment is money well spent. The Bain system attaches to the outlet to the left in the picture above.. The reservoir bag is located in a familiar vertical position with the pop-off just above. A pressure manometer is included. Adding a pop-off occlusion valve to the Bain Block completes a convenient and effective noncircle delivery system. As a reminder, these are not non-rebreathing systems unless oxygen flow rates are high enough to make them so. Minimum oxygen flow rates are generally considered to be 200 to 250 ml/kg/min. Low oxygen flow rates will lead to significant, potentially fatal, rebreathing of exhaled gases. |
These Bain Blocks are available through the company links below. |
