2.1 Warnings
•he CNAP™ Monitor 500 is not designed for intracardial use.
•Do not connect the device's air connectors to an intravascular system!
•Do not use the oscillometric cuff on patients with vascular prostheses!
•Keep the CNAP™ Monitor 500 out of reach of children!
•he CNAP™ Monitor 500 is not fit for operation in potentially explosive surroundings, as may arise
from usage or storage of flammable anaesthetics, skin detergents or skin disinfectants. Also, do
not use the CNAP™ Monitor 500 in a possibly combustible atmosphere (i.e. if the ambient air con-
tains more than 25% of oxygen or nitrous oxide gas).
•he operator has to prevent prolonged impairment of the patient's blood circulation during the
measuring process by inspecting the concerned limbs regularly. his is particularly important in the
case of continuous blood pressure measurement. During normal use, the pressure in the finger cuff
will be the same as in the artery and therefore greater than normal venous pressure. As a result,
depending on variables like skin temperature, thickness, patient age, perfusion or presenting state,
venous congestion of the finger distal to the cuff may be observed which will quickly subside with
the discontinuation of monitoring (blue fingers). Check the monitoring area frequently and discon-
tinue the continuous blood pressure measurement and remove all air connectors immediately in
case of any signs of reduced blood circulation.
•Do not use the compressed air supply valves with any devices of a third party manufacturer.
•Each device is designed for the concurrent measurement of only one patient/test subject at a time.
Never measure two or more patients at the same time, applying only one device!
•Please pay attention to the precautions regarding electromagnetic compatibility (see chapter 15.3 –
Electromagnetic compatibility).
•In perioperative settings, the CNAP™ Monitor 500 is not to be used without additional ECG moni-
toring for independent patient monitoring.

•Any chemicals needed for the use and maintenance of the device are only to be prepared and
stored in correspondingly designated containers in order to prevent confusion entailing possible se-
rious consequences.
•Medical devices like the CNAP™ Monitor 500 are to be operated only by accordingly trained persons
who can guarantee the proper handling of the device on the basis of their special training or their
skills and practical experience.
•he operator has to be familiar with the operation of the CNAP™ Monitor 500. Before each meas-
urement process, the operator has to check and control the due condition, operational reliability
and functional safety of the device.

General information
CNAP™ Monitor 500 Page 2-2 Version 3.5.1, PN: 21-FHZU-10002
•Before connecting any cables to a patient, all connecting cables need to be visually inspected for
signs of damage. Any faulty parts (e.g. cables or plugs) are to be replaced immediately. Only origi-
nal CNSystems Medizintechnik AG accessories and replacement parts are to be used.
•Please pay close attention to the proper storage of the device: Do not bend the cables or hoses
excessively or coil them up too tightly, as this might result in damaging cables and hoses. Any
damaged cables or hoses are to be replaced immediately.
•ake care to ensure regular and sufficient air circulation around the device. Also take into consid-
eration the necessary environmental conditions specified in this manual (see Appendix C – echnical
specifications).
•A thorough examination of the device for its operational reliability is due on a regular basis (ap-
prox. once every month).
•his manual is an integral part of the CNAP™ Monitor 500. By adhering to its safety measures and
recommendations, the operator ensures the correct use and operation of the device as well as the
operators' and the patients' safety. Notes and precautions of particular importance are highlighted
by the following symbols: , , (see chapter 1 – About this manual).

2.2.2 Blood pressure
CNAP™:
•In rare cases, it might happen that the device is unable to detect a continuous blood pressure sig-
nal. Usually, the middle and index fingers are best suited for applying the finger cuffs as their pha-
langes are the longest. If it is not possible to obtain a continuous blood pressure signal, it is, in
most cases, caused by a vasopathy. Warming the hand, for example in warm water, may solve the
problem.
•If no continuous blood pressure waveform is displayed within a few minutes, it is probably due to
an insufficient blood flow in the fingers. In this case, try using another pair of fingers or the other
hand. If this is not successful either, please check if the labeling on the CNAP™ double finger cuff
(symbol) is on the side of the back of the hand.
•o avoid mechanical damage to the finger cuffs, never start measuring without a finger in the
blood pressure cuff. Also, remove all objects (e.g. rings) from the fingers before measuring.
•During NBP measurements or venous stasis, the graphic display of the blood pressure waveform
may be physiologically influenced.
•Limitations: In certain cases, a continuous blood pressure measurement is not reliable and/or not
possible:
oWeak signal shown through indicator: low PI ≤ 1 on the CNAP™ Monitor 500 (see chapter 3.7 -
PI)
oReduced peripheral blood flow (peripheral shock, hypothermia, extreme centralization, extreme
hypothermia)
oArterial vascular diseases (arteriosclerosis, Raynaud’s syndrome, endarteritis obliterans, colla-
genosis, extremely advanced vascular diseases PAOD)
oNBP limitations (see below)

General information
CNAP™ Monitor 500 Page 2-3 Version 3.5.1, PN: 21-FHZU-10002

•Damaged or time-worn batteries might considerably reduce the maximal operating
time on battery. he accuracy of the device's battery charge status is only guaran-
teed when using undamaged batteries and under normal operation conditions.
CAUTION:
•otal discharge may damage the battery. herefore charge the battery at every op-
portunity.
•Immediately charge the battery with a battery charge status ≤ 25%, or as soon as
possible and for at least 5 hours at ≤ 50%.
•Extreme temperatures might impair your battery performance. For optimal operabil-
ity, charge and use the battery at temperatures < 35°C (95°F).
•In the case of infrequent use, charge the battery at least every 3 weeks for at least 5
hours.
•In order to guarantee a long product lifetime, preferably use the CNAP™ Monitor 500
