NOISY SIGNAL, CHECK ELECTRODES. Electrodes are making poor contact and
may be dried out. Replace electrodes.
Invasive pressure
This section applies only to Propaq Encore Models 204EL and 206EL. If you don't have
one of these models, you can skip this section.
Intended use
The Propaq Encore invasive pressure channel is intended for measuring arterial, venous,
and intracranial pressures using invasive transducers with 5
V/V/mmHg sensitivity. The
Propaq Encore can be used with many types of transducers, including nondisposable,
disposable dome, and fully disposable.
Invasive pressure connectors and transducers
Visit www.welchallyn.com for recommended transducers for use with this monitor. Do
not use light-sensitive disposable transducers. Transducers must be used according to
your hospital's standards and the manufacturer's recommendations. Always refer to the
manufacturer's Directions for Use before using the transducer.
WARNING If a disconnected lead is in too close proximity to other electrical
devices, it may cause false heart rate, a failure to detect apnea, or a failure to
display a Lead Fail message.
WARNING If electrocautery is used, always avoid using any transducer with a
conductive (metal) case that is electrically connected to its cable shield. Using a
conductive transducer case with such a shield connection risks high-frequency
burns at the ECG electrodes if the transducer case becomes earth grounded.
WARNING Although complete disconnections of invasive pressure transducers
will be detected by the normal alarm functions, partial disconnection will not be
detected, nor will the use of some incompatible transducers. The user must
exercise reasonable measures to ensure that approved transducers are used and
that pressure transducers are connected properly.
WARNING Before you use a Propaq on a new patient, always turn it off for a few
seconds, then turn it on again. This clears the prior patient’s trend values, alarm
limit settings, and NIBP cuff inflation target.
