  1. Calibrate at Phlebostatic axis?

    JayJ10 posted a topic in Critical Care
    This is a trivial question but I am curious as to the reason. I understand that a transducer must be leveled at the Phlebostatic axis in order to overcome hydrostatic pressure and get accurate readings, but why is it necessary to zero it at that level? Is overcoming atmospheric pressure the only reason for calibration? If so, this wouldn't make sense since atmospheric pressure will be the same no matter where the transducer is calibrated. I am surely missing something because I continue to hear experienced people state to zero at phlebostatic axis? Thanks for all your help, Jay
