2.1 Warnings
• The 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!
• The 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 con­tains more than 25% of oxygen or nitrous oxide gas).
• The operator has to prevent prolonged impairment of the patient's blood circulation during the measuring process by inspecting the concerned limbs regularly. This 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 discon­tinue 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.
2.2 Precautions
2.2.1 General precautions
• The CNAP™ Monitor 500 is a device of protection class II. The input ports of type BF are protected from defibrillation.
• According to the regulations of IEC 601-2-30/EN 60601-2-30, non-invasive blood pressure meas- urement is fit for use during electrosurgical surgery as well as during discharge of a cardiac defi­brillator.
• The CNAP™ Monitor 500 meets the requirements of EN 60601-1-1 and can be used next to pa- tients without restrictions.
• While using the CNAP™ Monitor 500, avoid compressing the air hoses or reducing their diameter in any way (e.g. by bending the cables) as this could impair the quality of the measuring signals.
• No liquids must ingress the CNAP™ Monitor 500. In case this should happen, the instrument must not be started up again until after inspection by a qualified technician.
• 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 se­rious 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.
• The 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 origi­nal 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.
• Take 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 –Technical specifications).
• A thorough examination of the device for its operational reliability is due on a regular basis (ap- prox. once every month).
• This 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).
• In order to ensure the device's faultless functioning, accuracy of measurement and immunity of interference as well as the patients' safety, use only original CNSystems accessories and replace­ment parts.

• All devices that get connected to the AUX, Ethernet and USB interfaces must meet EN 606950-1
standard.
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 pha­langes 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.
• To 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:
o Weak signal shown through indicator: low PI ≤ 1 on the CNAP™ Monitor 500 (see chapter 3.7 -
PI)
o Reduced peripheral blood flow (peripheral shock, hypothermia, extreme centralization, extreme
hypothermia)
o Arterial vascular diseases (arteriosclerosis, Raynaud’s syndrome, endarteritis obliterans, colla-
genosis, extremely advanced vascular diseases PAOD)
o NBP limitations (see below)

3.5 Patient setup
STOPP:
• Please be aware that CNAP™ finger cuffs as well as CNAP™ Cuff Controller needs to be setup without tension. The fixation of CNAP™ Cuff Controller is to be setup cen­trally (see illustration below). This obviates tension during a measurement due to dis­location of the patient which can disturb the CNAP™ measurement significantly.
1. Starting up the CNAP™ Monitor 500:
Press
Power On/Off
and confirm the alarm self-test (test
alarm signal) by pressing
Alarm Pause/Off.
2. Patient setup:
a) Choose the correct CNAP™ double finger cuff size by means
of the graphic on the CNAP™ controller. If a patient's finger size is between two cuff sizes, choose the larger cuff.
b) Assemble the CNAP™ hardware by connecting the CNAP™
double finger cuff, the CNAP™ controller, the CNAP™ cable with the CNAP™ Monitor 500. All plugs and connectors are designed so as to make it impossible to switch them acciden­tally.
c) Equip the patient with the CNAP™ hardware: The CNAP™
double finger cuff is placed on the proximal joints of the in­dex and middle fingers. Ensure that the cuff cables run along the outside of the patient's arm.
d) Fasten the CNAP™ controller to the patient's forearm by
means of the fixing cuff (with a Velcro fastener) and make sure that the hand with the CNAP™ double finger cuff is placed at heart level (see illustration on the side).
3. Putting on the NBP cuff:
a) Make sure that only NBP cuffs authorized by CNSystems are used and that you apply the
correct size to the patient (Child, Small Adult, Adult, Large Adult).
b) Place the blood pressure cuff on the patient's upper arm, preferably contralaterally, at
heart level. The marker on the NBP cuff should be directly above the brachial artery.
c) Connect the NBP cuff with the NBP air connector on the patient side of the CNAP™ Moni-
tor 500.
4. Starting the measurement:
d) New entry of patients:
Selecting the functions
New Patient - Adult Defaults
or
New Patient - Pediat-
ric Defaults
starts a new measurement automatically – previous measurements will be
deleted. Detailed patient data input can be performed at a later time via the
Alarm
frame
in the
Patient Data
menu.
e) Use current patient data:
When selecting the option
Use Current Patient Data
, all patient data is maintained.
To continue a measurement, press the
Start/Stop
key as the
Setup Patient
dialog
is not displayed automatically. After selection of the option
Use Current Patient Da-
ta
, the measuring process starts automatically.

Illustration 18: CNAP™- Controller-Fixation
3.6 Timer
The timer displays the CNAP™ change of finger and/or NBP measurements following within the next 30 minutes (calibration measurements), thus making the following measurement-related interruptions of continuous blood pressure perceptible and allowing adequate time management (see below).
All next calibration measurements within 30 minutes will be graphically displayed and are col­or coded (continuous bar graph display).
• Red = long interruption of measurement: CNAP™ change of finger (+ NBP measure­ment). The red bar always refers to a completely new calibration of CNAP™ change of finger (+NBP measurement) resulting in a longer interruption of continuous blood pressure of approx. 90 seconds.
• White = short interruption of measurement: NBP measurement The white bar always refers to an independent NBP measurement of shorter duration of approx. 45 seconds.
The immediate next calibration is displayed with
CNAP
or
NBP
to the left next to the bar
graph display and numerically as a countdown (mm:ss) to the right of the bar graph display.
Example 1:
The immediate next interruption is a CNAP™ change of finger (+ NBP measurement) in 10:31 minutes, followed by another NBP measurement in approx. 21 minutes, a CNAP™ change of fin­ger (+ NBP measurement) in 25 minutes and another NBP measurement in more than 30 min­utes.
Example 2:
The immediate next interruption is an NBP measurement in 10:47 minutes, followed by another CNAP™ change of finger (+ NBP measurement) in approx. 15 minutes and another NBP meas­urement in more than 30 minutes.
Page 25
Introduction
CNAP™ Monitor 500 Page 3-16 Version 3.5.1, PN: 21-FHZU-10002
NOTE:
• The timer is only displayed during active measurement (with available CNAP values) at the bottom of the
Parameter frame
.
• A manual
NBP: Start
resets the NBP timer: this means a reset of the NBP count-
down to
NBP: Cal Interval
set in the
Parameter
menu.
• A manual
CNAP: Change Finger
resets the CNAP timer. In addition, also a reset for the NBP is carried out as soon as the NBP is triggered by CNAP. This means a re­set of both the CNAP and the NBP countdown to the
CNAP: Cal Interval
and
NBP: Cal Interval
set.
TIME MANAGEMENT:
Example: As next calibration a CNAP™ change of finger (+ NBP measurement) will be in 5:00 minutes; however, continuous blood pressure will probably be essential at this time.
• Option 1: Delay interruption
The user delays the next calibration by increasing the
CNAP: Cal Interval
in the
Parameter
menu to max. 60 minutes. This option does not apply if the
CNAP: Cal
Interval
has already been set to 60 minutes.
• Option 2: Anticipate interruption
The user immediately starts a manual
CNAP: Change Finger
in the
Parameter
menu. This CNAP Change Finger resets both timers at the time of triggering CNAP or NBP. With
CNAP: Cal Interval
of 30 minutes, the subsequent interruption would
only be in 30 minutes, provided the
NBP: Interval
has not been set with a shorter
interval.
Option 1 and option 2 apply analogously to the NBP if this is planned as the next cali­bration.
3.7 Perfusion Index
The Perfusion Index (PI) describes the signal quality of perfusion in the finger artery in the CNAP™ cuff on a scale from 0 (no signal) to 6 (very good signal). The currently found PI is shown on the screen as a white bar. The maximum value that was found during the calibration phase is marked with a green rectangle in the bar graph (see example 1). Patients with a very bad peripheral blood circulation can be identified by means of a very low PI ≤ 1. Also a red rec­tangle at the very left position in the bar graph is displayed (see example 2). Such a case in­volves the risk of a CNAP™ interruption due to insufficient peripheral circulation, i.e., in the course of measurement it could fail temporarily or completely. The red rectangle will disappear if a PI > 1 will be found. During measurement, a temporary, too low signal quality will be displayed with the technical er-
ror message
CNAP: Artefact
.
If the signal quality is insufficient for more than 10 seconds,
particularly during the initialization phase, the technical error message
CNAP: Check Cuff –
Low Light Signal
will be displayed. A further NBP measurement by means of the CNAP™
Monitor 500 remains unaffected by this.
Example 1: current PI = 3, maximum found = 5 – good signal quality
Page 26
Introduction
CNAP™ Monitor 500 Page 3-17 Version 3.5.1, PN: 21-FHZU-10002
Example 2: current PI ≤ 1 - bad signal quality
NOTE:
• The Perfusion Index will only be displayed during the initialization phase (until NBP measurement -
NBP: triggered by CNAP
).
NOTE:
• The reason for a low light signal may be
• insufficient peripheral circulation
• or a misplaced CNAP™ finger cuff.
Before starting a new measurement the position of the finger cuff must be checked.

4.4 BP Wave Out (patient monitors)
4.4.1 BP Wave Out configuration
Similar to the BP waveform obtained from an invasive catheter (e.g. radial artery), the CNAP regis­tered blood pressure waveform can be interfaced to patient monitors by means of the "BP Wave Out" output port located on the left side of the CNAP™ Monitor 500 (see chapter 3.2.1, illustration 2). As can be seen from the graphics below, the CNAP™ Monitor 500 can also be connected with the patient monitor by a) CNAP™ Transducer Cable and b) IBP Interface Cable (see also chapter 15.2 - Connec­tions).
CNAP™ Monitor 500 Transducer Cable Interface Cable Patient Monitor
Page 29
Monitor configuration
CNAP™ Monitor 500 Page 4-3 Version 3.5.1, PN: 21-FHZU-10002
CAUTION:
• In order to connect the CNAP™ Monitor 500 to another patient monitor with invasive BP port, the following 2 compatible cables are needed (see compatibility list below):
• CNAP™ Transducer Cable: suitable for the different patient monitors and available in 4 colors (grey, blue, red, yellow). The cable is connected to the CNAP™ Monitor 500 (pa­tient side) and enables access to the CNAP™ blood pressure waveform using an RJ11 6P4C connector. The compatible CNAP™ Transducer Cable is a component for the CNAP™ Monitor 500 and is only available from CNSystems Medizintechnik AG.
• IBP Interface Cable: connects the IBP port of a patient monitor to the RJ11 6P4C con- nector of the CNAP™ Transducer Cable. Selected IBP Interface Cables (e.g. Abbott IBP catheter) are also available from CNSystems Medizintechnik AG.
Unlike the analog output port (see chapter 4.5 - Interfaces), the CNAP™ blood pressure waveform signal via the "BP Wave Out" is standardized. Its sensitivity always amounts to 5 µV/V/mmHg. The bridge voltage on the CNAP™ Monitor 500 depends on the supply voltage the patient monitor pro­vides.
If, for example, the supply voltage is 4 V, the sensitivity will be calculated as follows: 5 µV/V/mmHg x 4 V = 20 µV/mmHg

4.4.3 Zeroing
After having connected the CNAP™ Monitor 500 and the patient monitor using a) the CNAP™ trans­ducer cable and b) the IBP interface cable (see 4.4.1 - BP Wave Out configuration), zeroing must be performed:
a) Zeroing without active measurement:
Before and after an active measurement (without displayed CNAP values), zeroing is activated automatically (a zero signal is output). Zeroing can be immediately performed on the pa­tient monitor.
b) Zeroing during active measurement:
During an active measurement (with displayed CNAP values), zeroing is inactive; however, it can be activated manually in the
Parameter
menu:
1. CNAP™ Monitor 500: Activate zeroing via
IBP: Zeroing Start
2. Patient monitor: Performing the zeroing process
3. CNAP™ Monitor 500: Deactivate zeroing via
IBP: Zeroing Stop
Illustration 19: Parameter menu: IBP: Zeroing
NOTE:
• Usually a patient monitor will report successful zeroing (must be within ± 32 mmHg), e.g. by signaling "zero completed, offset is xx mmHg".
• If you don't deactivate
IBP: Zeroing Stop
and leave it on
Stop
, the pressure signal
on the patient monitor will display 0 mmHg.
Page 31
Monitor configuration
CNAP™ Monitor 500 Page 4-5 Version 3.5.1, PN: 21-FHZU-10002
CAUTION: In order to ensure full accuracy of the CNAP™ blood pressure waveform and its derived blood pressure values to another patient monitor, do not forget to perform an IBP zeroing when connecting the two devices. In addition, the CNAP™ waveform is to be zeroed ac­cording to your hospital regulation (but at least once a day). Plus, zeroing should be per­formed if there is any doubt as to the accuracy of obtained recordings and in the event of a new connection of the transducer to the monitor.
NOTE:
• Blood pressure values obtained by means of CNAP™ and invasively obtained reference values (e.g. radial measurement) may differ for the following reasons: a) Difference in beat detection b) Different settings for
Parameter Averaging
(see chapter 4.2 – Parameter Av-
eraging menu item)
c) Physiological differences due to different measuring positions (e.g. left-right, bra-
chial-radial)
d) During the initialization of CNAP measurement, at the start of measuring or change
of finger, the non-calibrated and then the measured blood pressure signal will be displayed (blood pressure waveform – see illustration 20 below). In order to avoid misinterpretation, the scale of the blood pressure waveform will be blanked in the meantime.

• With regard to the safe operation of the CNAP™ Monitor 500 as well as the unambi- guous identification and classification of measurements and prints, the input of pa­tient data is a prerequisite of essential importance. Entering the respective patient category, for instance, results in the subsequent adjustment of alarm limits as well as of the NBP cuff inflation pressure.
5.1 Patient entry
Patient entry and use of current patient data is done via the setup patient dialog appearing on the main screen immediately after a new patient has been set up with the CNAP™ double finger cuff.
NOTE:
• The
Setup Patient
dialog will be displayed automatically if a new patient is meas-
ured or if the CNAP™ double finger cuff was not applied for ≥ 5 seconds. In case the
Setup Patient
dialog is not displayed automatically despite correct application of the CNAP™ double finger cuff (detection error) or if the measurement is continued, it is displayed by pressing the
Start/Stop
key.

Illustration 21: Setup Patient Dialog
There are 2 ways for setup a patient before starting a measurement:
a) New Patient:
Selecting the functions
New Patient – Adult Defaults
or
New Patient – Pediat-
ric Defaults
automatically sets the respective patient category (adult, pediatric). Preset-
ting of the focus on
New Patient – Adult Defaults
or
New Patient – Pediatric
Defaults
can be defined in
Setup/Measurement/Patient Category
. As soon as a
category is selected, measurement starts automatically.
b) Use Current Patient Data (continue):
The
Use Current Patient Data
option can be selected in the
Setup Patient
dialog provided that a patient category has already been defined (current patient data is being used). After confirming the
Use Current Patient Data
option, the measurement will
automatically continue with a new initialization phase.
NOTE:
• While the
Setup Patient
dialog is displayed, it is not possible to complete further
patient data (e.g. name, gender) in the
Patient Data
menu (see chapter 5.2 - Edit-
ing of patient data). In such a case, the
Patient Data
menu will only be accessible
again after selection of a patient category.

The alarm system of the CNAP™ Monitor 500 distinguishes between two alarm levels: physiological alarms (yellow) and technical malfunction alarms (white).
• MEDIUM PRIORITY: **
Yellow alarms are physiological alarms of medium priority (e.g. exceeding the upper or falling be­low the lower limit for systolic blood pressure).
• LOW PRIORITY: *
Technical malfunction alarms indicate that the CNAP™ Monitor 500 is unable to take a measure­ment or to reliably detect possible alarm conditions. Instead of numeric values, the
Parameter
frame
displays three stars (***), accompanied by an acoustic signal which has to be confirmed by the operator (see chapter 6.3.1 – Acknowledgement of alarms). Depending on the indicated malfunction, the operator may have to take a measure (e.g. replace a defective CNAP™ double fin­ger cuff).
NOTE:
• The CNAP™ Monitor 500 has no other than the mentioned 2 alarm levels: physiologi- cal alarms (yellow) and technical malfunction alarms (white).
• Physiological alarms are deleted:
- by
Discharge
,
- by stopping the measurement using
Start/Stop
,
- by the next NBP measurement.
• Physiological alarms triggered by a single NBP measurement will be saved until the next NBP measurement.
STOP:
If several alarms are activated at the same time:
• The alarm signals will be displayed alternately in intervals of 5 seconds in the
Pa-
rameter frame
,
• Physiological alarms and technical malfunction alarms will be displayed one after the other in their order of appearance,
• The physiological alarm with the highest priority will be accompanied by an acoustic signal,
• New alarms and technical malfunction alarms will be displayed immediately.

6.2 Acoustic alarm signals
In accordance with the regulations of EN 60601-1-8, the CNAP™ Monitor 500 produces acoustic alarm signals. The differently coded alarm signals are repeated until acknowledged by pressing the
Alarm
Pause/Off
key.
NOTE: Repetition rate for acoustic alarm signals is:
• 5 seconds for physiological alarms,
• 18 seconds for technical malfunction alarms.
STOP:
• Do not rely solely on the acoustic alarm signals! Especially if the alarm volume is set low or has been turned off, alarms might be missed which could constitute a possible danger for patients!
The alarm signal volume is individually adjustable. Factory setting is 80% of maximum volume and can be adjusted from 20 to 100%. Maximum sound pressure amounts to 93 dB at a distance of 1 me­ter from the CNAP™ Monitor 500, whereas minimum sound pressure amounts to 60 dB at a distance of 1 meter from the device.

6.4.3 Auto limits
By means of the function
Auto limits
,
the operator is able to adjust alarm limits to a specific pa­tient. Therefore, it is necessary to wait for the monitor to display physiological signals of a measure­ment in order to be able to activate
Auto limits
.
Later, if patient data is deleted or new patient data
is entered, the function
Auto limits
will be deactivated automatically. Using this function leads to the alarm limits of activated alarms being adjusted to the currently meas­ured vital parameters. The alarm limits will then be set within a predefined safety range based on the measured individual parameters:
•
Narrow:
currently measured value Sys/Dia/Mean/Pulse ± 20mmHg
•
Wide:
currently measured value Sys/Dia/Mean/Pulse ± 30mmHg
•
Cancel:

9.1 General information
CNAP™ - Continuous Non-Invasive Arterial Blood Pressure – is a non-invasive method for measuring the continuous blood pressure waveform in adult and pediatric patients from the age of 4 years.
A patient's blood pressure waveform is recorded by the CNAP™ Monitor 500 by means of a double finger cuff with an integrated IR light sensor and air chambers. The measured IR signal – similar to a pulse oximeter – helps to measure the blood volume in the finger, which is kept constant by means of CNAP: beat to beat a counter pressure in the finger cuff is built up, which fluctuates between the sys­tolic and diastolic blood pressure.
Illustration 36: CNAP™ Technology
By means of NBP cuff (oscillometric blood pressure measurement), the relatively measured blood pressure in the finger is calibrated to absolute blood pressure values (to the pressure of a big artery at heart level), thus ensuring absolute accuracy. The NBP cuff can be placed on the patient's upper arm either on the same or on the other arm as the CNAP™ double finger cuff. NBP measurement is essen­tial to ensure absolute accuracy of the recorded blood pressure values.
CAUTION:
• The accuracy of the CNAP™ measurement depends on the accuracy of the accompa- nying NBP measurement, which is particularly important during calibrations or before interventions.
• Make sure that no movement artifacts occur during measurement, especially during and until approx. 2 min. after measurement initialization.
• Powerful light sources (e.g. cameras with flashlight) may affect the CNAP™ meas- urement and cause artifacts.
Page 60
CNAP
TM
CNAP™ Monitor 500 Page 9-2 Version 3.5.1, PN: 21-FHZU-10002
CAUTION:
• Movements of the patient, which result in changes of position of the CNAP™ double finger cuff regarding heart level, will have immediate influence on the absolute values of blood pressure readings. To compensate these physical effects (hydrostatic height), recalibrate the CNAP™ measurement by triggering a single NBP measure­ment (see chapter 10.6 - NBP options).
9.2 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 arti­facts), 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, immedi­ately 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 meas­urement process immediately!
• Before connecting any cables to a patient, visually inspect all components for dam- ages or wear. Any faulty parts are to be replaced immediately.
• Check the correct positioning of the CNAP™ double finger cuff regularly during meas- urement. Make sure that the cuff is not positioned on the finger joints.
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).

9.3 Setup
The CNAP™ hardware consists of the following components:
CNAP™ double finger cuff
CNAP™ controller
CNAP™ cable
Graphics to select correct finger cuff size
Illustration 37: CNAP™ hardware
NOTE:
• CNSystems recommends placing the CNAP™ double finger cuff on the index and the middle finger of a patient. In rare cases – if necessary – the CNAP™ double finger cuff may also be placed on the middle and the ring finger. Thumb and little fingers are not suited for CNAP™ blood pressure measurement.
• The use of a too big/too small CNAP™ double finger cuff may result in faulty blood pressure recordings.
Start/Stop a measurement (refer to chapter 3.5 – Patient se­tup):
• Choose the correct size of a CNAP™ double finger cuff by means of the graphics on the upside of the CNAP™ controller (refer to chapter 3.2.3 - CNAP™ controller).
• Assemble the CNAP™ hardware by connecting the CNAP™ double finger cuff, the CNAP™ controller, the CNAP™ cable and the CNAP™ Monitor 500. All the plugs and connectors are de­signed so as to make it impossible to switch them accidentally.
• Equip the patient with the CNAP™ hardware: The CNAP™ dou- ble finger cuff is placed on the proximal joints of the index and middle fingers. Make sure that the cuff cables run along the upper side of the patient's arm.
• Fasten the CNAP™ controller to the patient's forearm by means of the fixing cuff (with a Velcro fastener).
• Place the NBP blood pressure cuff on the patient's upper arm (calibration for CNAP™) contralat- erally, or, if necessary, on the same arm as the double finger cuff (refer to chapter 10 – NBP).
• As soon as you have selected a category in the
Setup Patient
dialog, the CNAP™ measure-
ment will start automatically.

10.1 General information
NBP (Non-Invasive Blood Pressure) uses the oscillometric method to determine a patient's blood pres­sure on a non-continuous basis. To achieve this, the NBP module is integrated into the CNAP™ Monitor
500. Blood pressure measurement is conducted by means of a NBP cuff (available in 4 sizes) which is placed around the patient's upper arm (brachial artery) and connected to the CNAP™ Monitor 500 on the left side of the monitor (see chapter 3 – Introduction). For measurement purposes, the pressure in the NBP cuff is controlled by the NBP module. The cuff pressure is first increased above systolic blood pressure and decreased step by step. The pulsations in the NBP cuff provide the basis for deriving the blood pressure values Sys and Dia.
NOTE:
• When a measurement process is started on the CNAP™ Monitor 500, a NBP meas- urement is also triggered automatically.
• However, it is also possible to trigger an NBP measurement manually at any time during measurement – except during display of the
Setup Patient
dialog (see
chapter 10.6 – NBP options).
• NBP measuring interval can be pre-set in the
Measurement
menu for every new
measurement and can be adapted via the
Parameter
menu during a measurement.
• Inflation pressure of the NBP cuff is determined by the selected patient category (see chapter 5.1 – Patient entry). During NBP measurement, it is graphically and numeri­cally displayed as a bar at the bottom of the
Parameter frame
(see illustration 42
below).
• Interruptions due to NBP measurements are displayed as white countdown bars in the
Parameter frame
(see chapter 3.6 - Timer).
• During an NBP measurement, neither venous stasis nor manual change of finger can be performed.
NOTE:
• The CNAP™ blood pressure waveform is calibrated by means of an oscillometric NBP measurement. If the accuracy of the NBP measurement is affected by artifacts (e.g. weak pulse, irregular pulse, artifacts from patient movement or tremor, or respira­tory artifacts), this may also affect and reduce the accuracy of blood pressure values measured by the CNAP™ Monitor 500.
• An NBP cuff can be put on the same arm as the CNAP™ double finger cuff (ipsilater- ally) or on the other arm (contralaterally).
Illustration 42: NBP measurement
Page 67
NBP
CNAP™ Monitor 500 Page 10-2 Version 3.5.1, PN: 21-FHZU-10002
10.2 Venous stasis
Venous stasis to support punctures of intravenous lines can be performed by means of the NBP cuff. After putting on the NBP cuff, venous stasis can be started by selecting
NBP: Start Venous Stasis
in the
Parameter
menu at any time. During venous stasis, the
NBP: Start Venous Stasis
sta­tus message is displayed (see illustration below). Depending on the selected patient category, the NBP cuff is inflated to constant pressure levels of 80mmHg for adults and 60mmHg for pediatric patients.
NOTE:
• During venous stasis, the cuff inflation pressure is graphically displayed as a bar at the bottom of the
Parameter frame
(analogous to the NBP measurement, see
chapter 10.1 – General information).
• Until the target pressure of 80/60mmHg is reached, the pressure is displayed nu- merically to the right of the bar.
• After the target pressure has been reached, the numeric display of pressure is re- placed by the time remaining until automatic stop of venous stasis (see illustration 43 below).
• Venous stasis can be performed for max. 2 minutes. If venous stasis is not termi- nated prematurely by selecting
NBP: Stop Venous Stasis
manually, it will stop automatically after 2 minutes. In case it was performed during an ongoing CNAP measurement, it will be continued afterwards automatically.
• Numeric display of continuous blood pressure is not available during venous stasis; however, the blood pressure waveform will continue to be displayed (without scale).
• Venous stasis cannot be performed while the
Setup Patient
dialog is displayed.
• Neither manual NBP nor manual change of finger can be performed during venous stasis.

CNAP™ Monitor 500 Page 10-3 Version 3.5.1, PN: 21-FHZU-10002
10.3 Safety precautions
STOP:
• Patient category: Make sure to select the correct patient category before starting a measurement (see chapter 5.1 – Patient entry). The higher adult levels of inflation pressure of the NBP cuff, excess pressure limits or measuring time for instance, must never be used for pediatric patients!
• Intravenous infusion lines: Never put on an NBP cuff to a limb already connected to an intravenous infusion line or an intra-arterial catheter. The inflation of the cuff might result in the infusion solution being caught up or even cause tissue damage to the punctured area.
• Cutaneous lesions: Never perform NBP measurements in patients suffering from drepanocythemia or from cutaneous lesions, or in patients where cutaneous lesions are to be expected.
• Unsupervised measurements: Patients with severe blood coagulation dysfunction may develop haematoma on the limb where the NBP cuff has been inflated. In these cases, carefully consider the pros/cons of frequent unsupervised blood pressure mea­surements.
• Interference by external devices: Results of NBP recordings are not to be used if the measured oscillometric pulse has been influenced by other devices or techniques (e.g. contrapulsation).
• Interpretation: NBP recordings are to be interpreted only by a physician or medical professional staff.
• Limitations of NBP measurements: NBP recordings may be inaccurate or even impossible under the following conditions:
o lack of detectable regular arterial blood pressure, o arrhythmia, o strong and persistent patient movement (e.g. tremor or convulsions), o rapid blood pressure fluctuations, o severe shock or hypothermia with reduced peripheral blood flow, o obesity, as adipose tissue in the limbs muffles arterial oscillations.
NOTE:
• In order to ensure the accuracy of NBP measurements, be sure to choose the right size of the upper arm cuff. Selecting the wrong size or incorrect attaching of the cuff may cause significant inaccuracies of recordings!
• In case of longer monitoring, be sure to inspect the correct blood supply of the pa- tient's limbs on a regular basis.
• The NBP cuff is made of latex free and skin-friendly synthetic material.

Page 70
NBP
CNAP™ Monitor 500 Page 10-5 Version 3.5.1, PN: 21-FHZU-10002
Start/Stop a measurement:
1. Make sure you are using an NBP cuff authorized by CNSystems and make sure to use the correct size.
NOTE:
• The width of the cuff should be between 37% and 47% of the circumference of the patient's limb. The inflatable part of the cuff should be at least 80% of the respective extremity.
• The following NBP cuff sizes are available:
Size Arm circumference (cm)
Child 12 - 19
Small Adult 17 - 25
Adult 23 - 33
Large Adult 31 - 40
2. Attach the NBP cuff on the upper arm of the patient at heart level. The marker on the NBP cuff should be directly above the brachial artery.
NOTE:
Do not attach the cuff too tightly around the limb as this might cause problems during inflation and deflation of the cuff and lead to ischemia of the extremities. Be sure to inspect the patient's skin (color, temperature, sensitivity of limb) around the cuff on a regular basis. Should any signs of alterations to the skin or decreased blood supply be noticeable, immediately change arm or stop the blood pressure measurement alto­gether.
3. Connect the NBP cuff with the NBP air connector on the left side of the CNAP™ Monitor 500.
4. There are 2 ways to start an NBP measurement:
a) The start of a CNAP™ measurement also automatically starts an NBP measurement. NBP
measurements are performed after the calibration phase of the CNAP™ Monitor 500 or automatically in defined time intervals. To set the desired time intervals, access either the
Parameter
menu or the
Measurement
menu.
b) Starting a single measurement by using the click-wheel control to access the
Parame-
ter
menu.
NOTE:
The NBP measurement serves to calibrate the CNAP™ blood pressure measurement at the height of the heart.

Cleaning............................................................................................................................. 11-1
Disinfection ........................................................................................................................11-2
Only use disinfectants and detergents recommended by CNSystems Medizintechnik AG to clean or disinfect the device and its accessories. CNSystems’ warranty does not cover any damage caused by the use of unsuitable cleaning agents or methods. The warranty of CNSystems does not apply to the effectiveness of the mentioned cleaning agents and methods for the purpose of infection prevention and control. When in doubt, the operator should con­tact the hospital hygiene department. This particularly applies for the effectiveness of disinfectants and detergents against hepatitis B and HI viruses. The operator is to follow the regulations of the re­spective hospital and country.
11.1 General precautions
The CNAP™ Monitor 500 including all its components and accessories are to be kept clean and free of dust. After cleaning and disinfecting the devices, they must be thoroughly inspected before use. If any components show signs of wear or damage, these components must not be used for patient meas­urements! Before sending devices and components back to CNSystems Medizintechnik AG, they are to be decontaminated.
CAUTION:
• Always dilute detergents according to manufacturers' instruction, or use in the small- est possible concentration.
• No liquid must ingress the CNAP™ Monitor 500.
• Do not dip instruments, device parts or components in liquid.
• Do not pour any liquid directly on the device.
• Do not let residues of detergents or disinfectants air-dry on any parts of the device.
Wipe them off with a cloth moist with water, then dry the instruments with a clean cloth.
• Never use scouring agents or abrasive detergents (e.g. steel wool or silver polish).
• Do not use bleaching agents!
• Wipe off detergents and disinfectants with a moist cloth (water), then dry surfaces
with a clean cloth.
STOP:
No liquid must be spilt on any part of the CNAP™ Monitor 500. In case this should hap­pen, carefully dry device/accessory. If in doubt whether liquid has ingressed the device, do not start up the instrument. Contact technical staff or a service partner of CNSystems Medizintechnik AG.
11.2 Cleaning
In order to clean any part of the device use a lint-free cloth, moist with warm water (max. 40° C), and soap, diluted non-caustic detergents, tensides or detergents containing ammonia or alcohol. Do not use strong solvents like dimethylketone or trichloroethylene. Do not dip the device, any part of the device or any accessories (especially not the hoses) into liquid. As the screen of the CNAP™ Monitor 500 is easily scratched, be particularly careful when cleaning it. No liquid must enter the CNAP™ Monitor 500, so be sure to not spill any liquid directly on the monitor. No liquid must enter the connectors of the CNAP™ Monitor 500 or the CNAP™ controller, so take care not to wipe over, but rather around the connectors when cleaning them.

In comparison with standard thermal paper for POS or fax, this high quality paper is characterized by a considerably higher degree of resistance against substances, i.e. alcohol, grease, PVC or plasticisers, oil, hand lotion or cream, etc. This results in your prints being readable and storable for a longer time. If stored properly, KANZAN guarantees archivability of at least 7 to 10 years when using this kind of paper. High quality non-topcoated thermal papers like this are also resistant to the influence of exter­nal substances like oil, grease or water.
In addition, the characteristics of this high quality paper positively influences the product lifetime of your thermal printer. The characteristics of the above-mentioned KANZAN paper regarding chemical composition, thickness, surface texture ..., have material influence on the print head as well as the printer mechanism. The use of papers with lower dynamic sensitivity requires a higher level of energy transfer of the printer, while papers with a rougher surface lead, among others, to increased abrasion or mechanical strain. All these parameters automatically entail a considerable reduction of your print head product lifetime.
For these reasons, only use the recommended paper brands or a thermal paper marked as top-quality by the manufacturer. However, when using other paper brands, CNSystems Medizintechnik AG cannot guarantee for the printer’s economic lifespan as this can cause damage or staining of the print head.

Where P is the maximum output pow­er rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recom­mended separation distance in meters (m). Field strengths from fixed RF trans­mitters, as determined by an electro­magnetic site survey, should be less than the compliance level in each frequency range b. Interference may occur in the vicinity of equipment marked with the follow­ing symbol:
Note 1 At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellu-
lar/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accu­racy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the CNAP™ Monitor 500 is used exceeds the applicable RF compliance level above, the CNAP™ Monitor 500 should be ob­served to verify normal operation. If abnormal performance is observed, addi­tional measures may be necessary, such as reorienting or relocating the CNAP™ Monitor 500.
b Above the frequency range 150 kHz to 80 MHz, field strengths should be less
than 1 V/m.
