etc.) to the proximal, female luer lock port of the
Compass Cast per hospital protocol (Figure 6).
12. Depending on the application, connect the distal, male luer
lock end of the Compass Cast to accessory (e.g. needle,
distal lumen of a central line, extension set or needleless
valve in contact with patient) (Figure 7).
WARNING: Pressure reading is NOT physiological if
either the front or rear of the Compass Cast is open
to atmospheric pressure.
13. Pressure is displayed on the Compass Cast LCD and
the patient monitor (Figure 8).
NOTE: If Compass Cast pressure reading does not return
to zero after removal from accessories, flush device with
saline, open it to atmospheric pressure, and then cycle
device (power it off and then power back on) to recalibrate.
To Power Off and Recalibrate
Press and hold button for two seconds until “---” is displayed
on the LCD (Figure 9), then release button to power off
the device. To recalibrate, depress the power button for
approximately one second until the LCD reads “00”.
If procedure warrants, insert guidewire (up to 0.038˝ diameter)
through the Compass Cast guidewire port and into vessel.
Smaller guidewires may necessitate the use of the guidewire
insertion tool accompanying the guidewire holder (Figure 10).
WARNINGS
When finished using the Compass Cast, power it
off before discarding to prevent inadvertent pairing.
Do not reinfuse blood or other bodily fluid into
the patient after any such fluid is drawn into the
Compass Cast.
Do not reuse Compass Cast for different procedures
with different patients. Use a new Compass Cast
device for each procedure with each patient.
