VitalsBridge Directions for Use
43
rev. A.5
A: First check that the cable from the monitor is secure and not leaking at both the monitor’s connector
and at the
VitalsBridge connector. Ensure that NBP tubing and connections are not leaking. Ensure that none of the cuff tubes
are kinked. Ensure that the VitalsBridge is running.
CO2
Q: How long will each CO
2
cartridge last?
A: When the VitalsBridge is running, a 16g CO
2
cartridge will last 8 hours or longer, depending on the simulation. When
the regulator is not in use, turn the regulator to off, disconnect the tubing connection from the luer fitting on the
VitalsBridge and securely fit the cap on the end of the regulator tubing, without over tightening.
Q: My CO
2
regulator has a partially full cartridge that I wish to empty and dispose, what do I do?
A: Turn the regulator to off. Disconnect the regulator from the VitalsBridge by unscrewing the luer fitting. Hold the
tubing approximate 3-5 cm away from the end of the tubing.
Slowly
turn the knob on the regulator to let the gas
escape at a low flow rate from the outlet of the regulator until no more gas release is heard or felt. Take care when
removing the empty cartridge. It may be very cold.
Q: My monitor is not showing a CO
2
waveform, what should I check?
A: Check that the CO
2
cartridge is not empty. Ensure the monitor uses side stream capnography. Ensure that the CO
2
sampling line is connected properly to the VitalsBridge and the monitor. Ensure that CO
2
is enabled in the software.
If using the Manual Tab of the VitalsBridge C
onnector, ensure that “Force CO
2
Off” is unchecked.
If using a LLEAP
patient simulator, ensure that the CO
2
checkbox is ch
ecked in the “My Learner Buttons” section.
Consider re-
calibrating the CO
2
.
Invasive Blood Pressure
Q: I see a blood pressure waveform on the vital signs monitor, but there is no number being shown. What is the
problem?
A: The monitor’s blood pressure must be zeroed.
In the software that is used to control the patient simulator, ensure the
invasive bloo
d pressure waveform is set to “flat line” (i.e., the set pressure is a continuous value of zero over time)
.
On the patient monitor,
apply the “zero blood pressure” function
, making certain you select the correct transducer.
Disable
“
flat line
”
for the blood pressure waveform in the software that is used to control the patient simulator
Q: The invasive blood pressure readings on my monitor are inaccurate (more than 5-10 mmHg from the set value). What
is wrong?
A: Ensure that the monitor has been pr
operly zeroed by enabling the “f
lat
line” feature on the invasive blood pres
sure
waveform of interest in the software that controls the patient simulator. Then use the zero blood pressure feature on
the vital signs monitor (consult the vital signs monitor documentation).
Q: My monitor came with a cable that connects from the monitor to an invasive blood pressure transducer. However, it
does not fit the invasive blood pressure cables or connections on the VitalsBridge. How do I find the right connector?
A: You may purchase the proper invasive blood pressure cable kit for your Vital Signs monitor that is compatible with the
VitalsBridge. Consult
(or e-mail
) for additional information.
Q: How do I simulate a pulmonary-capillary wedge pressure with the VitalsBridge?
A: Ensure the software that controls the patient simulator can send PCWP (e.g., pre-
LLEAP Laerdal SimMan 3G’s are
incompatible with sending PCWP to the VitalsBridge). Then, follow the instructions on page 36.
