Safety precautions
CAUTION:
•
Do not use CNAP
®
and NBP in patients with vascular prostheses!
•
CNAP
®
is designed for the concurrent measurement of only one patient at a time.
•
Be sure to follow local regulations regarding storage of the CNAP
®
Monitor 500, its
accessories and packing material.
•
Keep the CNAP
®
Monitor 500 out of reach of children!
•
The CNAP
®
blood pressure waveform is calibrated by means of oscillometric NBP
measurement. If the accuracy of the NBP measurement is affected by artifacts (weak
pulse, irregular pulse, artifacts from patient movement or tremor, or respiratory arti-
facts), this may also affect and reduce the accuracy of values measured by the
CNAP
®
Monitor 500.
•
The use of technical surgical devices might cause interference and reduce the quality
of CNAP
®
recordings.
•
Never connect the device's air connectors to an intravascular system!
•
Regularly inspect the patient’s limbs during measurement to avoid possible lasting
damages caused by prolonged impairment of the patient's blood circulation! In case
of any signs of total arterial compression in a finger during measurement, immediate-
ly discontinue the measurement process by pressing
Start/Stop
on the front panel
of the CNAP
®
Monitor 500.
•
Pain or strong feelings of discomfort are in no way normal and are not a part of
CNAP
®
measurements! Should a patient report any of these feelings, stop the mea-
surement process immediately!
•
Before connecting any cables to a patient, visually inspect all components for damag-
es or wear. Any faulty parts are to be replaced immediately.
•
Check the correct positioning of the CNAP
®
double finger cuff regularly during mea-
surement. Make sure that the cuff is not positioned on the finger joints.
•
Measurements in patients where the dicrotic notch has a lower value than the diasto-
ly may show wrong values for all parameters.
NOTE:
•
Avoid compressing the air hoses or reducing their diameter in any way (e.g. by bend-
ing the cables) as this could impair the quality of the CNAP
®
measurement. To avoid
mechanical damage to the CNAP
®
finger cuff, remove all objects (e.g. rings) from the
patient’s fingers before measuring.
STOP:
•
The operating environment for CNAP
®
hardware has to comply with the directions
regarding ambient temperature, relative humidity and atmospheric pressure.
•
Take care to ensure regular and sufficient air circulation around the CNAP
®
Monitor
500 by placing the device accordingly (e.g. do not cover it with sheets or blankets).
•
In some cases, CNAP
®
measurement is not suitable (see chapter 2.2.2 – Limitations).
