We use the Becker system for ventrics.
we use a nonflush transducer for pressure monitoring. The current problem is how to zero the transducer? Half the staff say we have to open the stopcok to air to zero, the other half say never open the system to air. the procedure doesn't say either way, and we are without an educator.

I hope this response is not too late.

We use the Becker system for ventrics also and Yes! you have to zero it by opening the stopcock to air after you have leveled it at the outer cantus of the eye or top of the ear. Make sure the system has been primed with a non-bacteriostatic saline.
