    ​We utilize the OnGuard device and have had some challenges with the deadspace and the increased workflow to prime so I am intrigued to follow the thread.

    For the syringe pumps, pharmacy primes through the adaptor so there is no air or deadspace.

    This process (for both a nursing and pharmacy) can be cumbersome and definitely has a cost since it requires attaching both pieces of the CSTD adaptors just to prime through.

    Can’t wait to see what others are doing

    Hi All,
    We recently implemented Equashield for our closed system transfer device (CSTD). There is free air in the adapter(s) dead space that in some circumstances cannot be primed (e.g. syringe pump). The maximum free air is around 0.17mL. Curious if anyone has a contact at their institution to help address the following questions?

    1. What is the current threshold for pumps to alarm when detecting air in lines?
    2. Does your institution NOT use CSTDs on select IV administrations due to potential increase for air in line?

    Thanks so much,
