NOTE: The transducer is always leveled to the mid right atrium.
Zero the transducer and pressures whenever the patient's
position is changed.
4. Open the line to the patient.

pressure transducer or cable, and whenever patient's position is
changed. If any channel has not been zeroed, the message 'InvBP's
not zeroed' appears. The invasive pressure alarms advance to
medium and high priority levels regardless of the zeroing.
NOTE: IBP transducers must comply with the requirements of IEC
60601-2-34, must be provided with defibrillator protection, have a
frequency response exceeding 15Hz and contribute not more than
2mmHg to the overall measurement error.
