or configuring the system in a way not described in
these instructions will not meet this standard. Failure to
use the device as instructed may increase the risk of
electrical shock to the patient/operator.
Do not modify, service or alter the product in any
way. Servicing, alteration or modification may affect
patient/operator safety and/or product performance.
Precautions
Do not use if the package or the pressure cable is
damaged. Damage may include cracks, scratches, dents
or any signs that the housing may be compromised.
HemoSphere Pressure Cable Setup
Refer to the HemoSphere advanced monitor
operator's manual, available at eifu.edwards.com,
for comprehensive monitoring procedures with
that monitor.
1. Connect the HemoSphere pressure cable to
a compatible monitor at the end indicated
by ④ in figure 1.
2. Setup and initiate the compatible monitor.
3. Insert the appropriate color insert at ②
to indicate the monitored pressure type.
The colors are as follows:
• Red for arterial pressure (AP)
• Blue for central venous pressure (CVP)
• Yellow for pulmonary artery pressure (PAP)
• Green for cardiac output (CO)
4. Connect the pressure sensor to the pressure
cable. The pressure cable LED that surrounds the
zero button at ③ will flash green indicating
that the pressure sensor is detected. A yellow
light indicates a sensor fault condition. If this
occurs, refer to the monitor screen for specific
fault condition details.
5. Follow all instructions found in pressure
monitoring catheter IFU for catheter preparation
and insertion procedures. The HemoSphere
pressure cable must be zeroed before monitoring.
Zero Pressure Cable
1. To initiate the zeroing process, press and hold the
zero button indicated by ③ in the figure or
initiate zeroing process on the connected monitor
screen. Refer to the compatible monitor operator' s
manual for on‑screen zeroing instructions.
Caution: To prevent cable damage, do not apply
excessive force to the pressure cable zero button.
2. Level the sensor stopcock valve (vent port)
to the patient's phlebostatic axis position
according to the instructions for use.
3. Open the stopcock valve to measure
atmospheric conditions.
4. Press and hold the pressure cable zero button
or the on‑screen button to complete zeroing
process. The zero button LED will turn off when
properly zeroed.
5. Confirm stable zero pressure and turn stopcock
such that sensor is reading patient intravascular
pressure.

Do not use the HemoSphere pressure cable in an MR
environment. The pressure cable is MR unsafe since
the device contains metallic components, which can
experience RF‑induced heating in the MRI environment.
