5.1 Alarm classification

The alarm is classified as physiological alarm, technical alarm and prompt message based on the property of alarms.
1. Physiological alarm Generally, physiological alarm is activated in the following situations: one of the patient's physiological parameters exceeds the alarm limits, or the patient appears physiological abnormal, for example, HR exceeding the set limit. The information of physiological alarm is displayed in physiological alarm area.
2. Technical alarm Technical alarm represents the alarms activated by abnormal monitoring or monitoring result distortion due to system failure, such as lead-off or low battery. The information of technical alarm is displayed in technical alarm area.
3. Prompt message Except the physiological alarm and technical alarm, these messages refer to the displayed information about system status, which are not involved with patient vital signs. Prompt messages are often displayed in technical alarm area. Besides, some prompt messages are displayed in parameter area, for example, the messages related to NIBP are displayed in NIBP area.

5.2 Alarm level

The alarm is classified as high-level alarm, medium-level alarm and low-level alarm according to its severity.
1. High-level alarm High-level alarm indicates the patient’s life is in danger or the monitor under using has serious problem in technical respect. It is the most serious alarm.
2. Medium-level alarm Medium-level alarm means serious warning.
3. Low-level alarm Low-level alarm is a general warning.
NOTE: The level of all technical alarms and prompt messages and some of the
physiological alarms are determined by the system, which can not be changed by user.
The level of most of the physiological alarms need to be set by user, such as
alarm limits.

5.3 Alarm mode

When alarm occurs, the monitor may draw the user’s attention in three ways as below

Medium: "beep--beep-beep", frequency: every 8 seconds Low: "beep", frequency: every 8 seconds
Sound pressure range: 45 dB~85 dB
5.3.2 Light alarm
When alarm occurs, the alarm indicator will prompt different levels of alarms with different colors and flicker frequencies.
High: alarm indicator flickers in red with high frequency Medium: alarm indicator flickers in yellow with low frequency Low: alarm indicator lights in yellow without flickering
5.3.3 Alarm message
When alarm occurs, alarm messages will be displayed in physiological alarm area and technical alarm area. For physiological alarms, the following marks will be used in front of the messages to indicate the alarm level.
High: *** Medium: ** Low: *
The system also adopts different background to indicate the alarm level of physiological alarm and technical
alarm.
High: red  Medium: yellow  Low: yellow
NOTE: If one monitoring system has multiple alarm equipment, when an alarm
occurs, the visual and audio prompts generated by all alarm equipment should keep the same.
The way of alarm prompting is related to its level. When alarms of different levels occur at the same time, the monitor prompts
the highest level alarm among them.

item gives you the names of all frozen waveforms displayed on the screen. WAVE 2: to select the second frozen waveform to record. The pull-down list of
this item gives you the names of all waveforms displayed on the screen.
RECALL: to review frozen waveforms. REC: after selected, the system begins recording the frozen waveforms selected
in "WAVE 1" and "WAVE 2". EXIT: after pressed, the system closes the FREEZE menu and exits the Freeze
status.
Page 46

6.3 Reviewing Frozen Waveform

By moving the waveform, you may review a waveform of 34 seconds before the moment when it is frozen. For a waveform less than 34 seconds, the remaining part is displayed as a straight line. Use the rotary knob to move the cursor to the "RECALL" option on the FREEZE menu. Press the knob, the option displays "L-RIGHT". By turning the knob left or right, the frozen waveform on the screen will move left or right correspondingly. There is an arrow indicating upward under the right side of the last waveform. There is also a time scale beside the arrow. "0 s" is used to mark the moment when waveforms are frozen. With waveforms moving right, this time mark will turn into "-1 s, -2 s, -3 s…".

6.4 Recording Frozen Waveform

In the Freeze status, you may output displayed frozen waveforms via the recorder. Maximum 2 waveforms can be output at one time. On the FREEZE menu, the pull-down lists of both "WAVE 1" and "WAVE 2" give you all names of frozen waveforms on the screen, from which you may select two waveforms. Select the "REC" option on the FREEZE menu to output parameters generated upon the freezing moment and the two selected frozen waveforms. If one of the two selected waveforms is set off or not available, only parameters and the other waveform are recorded. If these two selected waveforms are all set off or not available, only parameters are recorded. As for the function of recording frozen waveforms, you can only record the waveforms displayed upon the freezing moment. The recording time length is the same as the length of the waveform displayed on the screen. For example, if the speed of a waveform is relatively fast, then it needs shorter time to record it. When recording frozen waveforms, the system is still in the Freeze status. After completion of this recording, if required, you may select another waveform to be output, and select "REC" option again to record until the all necessary waveforms are recorded. You may also record frozen waveforms by pressing the "REC/STOP" button on the front panel. If selecting "REC" option without installing a recorder, the system will prompt "RECORDER ERROR" in the status bar. For more detailed information about recording, please refer to the chapter Recording.

Chapter 9 Drug Calculation and Titration Table

This Portable Patient Monitor provides drug calculation and titration table display functions for fifteen drugs and outputs the content of titration table on the recorder.

9.1 Drug Calculation

The drug calculations that can be performed by the system are AMINOPHYLLINE, DOBUTAMINE, DOPAMINE, EPINEPHRINE, HEPARIN, ISUPREL, LIDOCAINE, NIPRIDE, NITROGLYCERIN and PITOCIN. Besides DRUG A, DRUG B, DRUG C, DRUG D and DRUG E are also provided to flexibly replace any of the drugs. Select "DRUG CALC" in SYSTEM MENU, the following interface will appear:
The following formulas are applied for dose calculation:
Concentration= Amount / Volume
INF Rate= Dose/Concentration
Duration= Amount / Dose
Dose= Rate × Concentration
Operating method:
In the Drug Calculation window, the operator should first select the name of the drug to be calculated, and then confirm the patient weight. Afterwards, the operator should also enter other known values. Turn the knob to move the cursor to each calculation item in the formula, press the knob and turn it to select a value. When the calculated value is selected, the result of other items will be displayed correspondingly. Each calculation item has a range limit, and if the result is out of range, the system will display "---.--".
NOTE: For the drug calculation, the prerequisite is that the operator must first of all
enter the patient weight and drug name. Values given by the system at the beginning are a group of random initial values, which cannot be used as the
Page 65
56
calculation reference. Instead, a new group of values suitable for the patient should be entered according to doctor’s advice.
Each drug has its fixed unit or unit series. Operator must select the proper
unit following the doctor’s instruction. The unit will automatically adjust itself in its unit series according to the input value. If the result expressed by this unit exceeds the range, the system will display "---".
After entering a value, a conspicuous prompt will appear in the menu
warning the operator to confirm the correctness of the entered value. The correctness of input value is the guarantee for the reliability and safety of the calculated results.
In neonate mode, Drip Rate and Drop Size items are disabled. For each entered value, the system will always give a dialog box asking for
user’s confirmation. You must be careful when answering each box. The calculated result is reliable only when the entered values are correct.
Select the drug name: Turn the knob to pick the DRUG NAME item. Yo u may
select the drug name in the pull-down list, including AMINOPHYLLINE, DOBUTAMINE, DOPAMINE, EPINEPHRINE, HEPARIN, ISUPREL, LIDOCAINE, NIPRIDE, NITROGLYCERIN, PITOCIN, Drug A, Drug B, Drug C, Drug D and Drug E. Calculation for only one type can be generated each time.
NOTE: Drug A/B/C/D/E are only codes for drugs instead of their real names. The
units for these five drugs are fixed. The operator may select the appropriate units according to the convention of using these drugs. The rules for expressing the units are:
"mg" series units are fixedly used for drug A, B and C: g, mg, mcg. "unit" series units are fixedly used for drug D: unit, k unit, m unit. "mEq" is fixedly used for drug E.
Patient weight: After accessing the DRUG CALC window, the operator should
enter the patient weight into the first or the second item. The entered weight will be used as the independent data only for the calculation of drug concentration.
NOTE: This drug calculation function acts only as a calculator. Information in this
interface may not related to the patient being currently monitored. That means the patient weight in Drug Calculation menu and the data in Patient Information menu are independent from each other. Therefore, if the Weight in Patient Information changes, the value in Drug Calculation will not be affected.

9.2 Titration Table Access titration table:

Select "DRUG NAME" item in DRUG CALC menu, confirm your selection, then select "TITRATION≫" to enter the titration table interface.

Chapter 10 ECG Monitoring

10.1 Introduction

The ECG monitoring produces a continuous waveform of the patient's cardiac electric activity to enable an accurate assessment of patient's current physiological state. Only proper connection of the ECG cables can ensure satisfactory measurement. The monitor displays 2-channel ECG waveforms at the same time in normal working, and provides 3/5-lead monitoring, ST segment analysis and arrhythmia analysis.
The patient cable consists of 2 parts; The cable that connects to the monitor; The lead set that connects to the patient. For 5-lead monitoring, the ECG can derive two waveforms from two
different leads. It is available to choose a specified lead to monitor from the left side of ECG waveform by using the knob.
The monitor displays the Heart Rate (HR), ST segment and Arrhythmia
analysis.
All parameters above can be set as alarm parameters.
NOTE: In the default settings of the monitor, the ECG waveforms are the top two
waveforms displayed in the waveform area.

10.2 Safety information

WARNING
Do not touch the patient, table nearby, or the equipment during
defibrillation.
Use only the ECG cables and electrodes provided by our company for
monitoring.
When connecting the cables and electrodes, please do make sure that the
cables and electrodes are not in contact with any conductive part or the earth, especially all the ECG electrodes, including neutral electrodes are securely attached to the patient. Do not let them contact with any conductive part or the ground.
Check the skin attached with ECG electrode patches for irritation everyday. If
there is a sign of allergies, replace the electrodes every 24 hours or change the sites.
Before starting the monitoring, inspect whether the lead works normally.
Unplug the ECG cable from the socket, the screen will display the error message "ECG LEAD OFF" and the audible alarm will be activated.
NOTE:
Please use defibrillation proof ECG cable during defibrillation. Interference from a non-grounded instrument near the patient and ESU

interference can cause inaccuracy of the waveform.
When a ECG device is unable to work, such as "ECG module communication
stopped", "ECG module communication error" or "ECG module initialization error" appears, the monitor will stop monitoring automatically, and the prompt system alarm, which is a high-level alarm.
For protecting environment, used electrodes must be recycled or disposed
properly.

10.3 Monitoring Procedure

10.3.1 Preparation
1. Prepare the patient's skin prior to placing the electrodes.
The skin is a poor conductor of electricity, therefore preparation of the patient's skin is important to facilitate good contact between electrodes and skin.
Shave hair from the sites where electrode patches attach to, if necessary. Wash sites thoroughly with soap and water. (Never use ether or pure
alcohol, because this increases skin impedance). Rub the skin briskly to increase capillary blood flow in the tissues and remove skin scurf and grease. Before installing the electrodes, let the skin dry completely.
2. Attach clip or snap to electrodes prior to placement.
3. Install the electrodes on the patient. Before attaching, apply some
conductive paste on the skin if the electrode does not contain conductive paste itse lf.
4. Connect the electrode lead to the patient cable.
5. Make sure the monitor is ready with power supply.
10.3.2 Choose Lead Type
1. Select the ECG parameter area, enter the ECG setup menu.
2. Set the "LESD TYPE" to "3 LEADS" or "5 LEADS" according to the lead type you applied.
10.3.3 Installing ECG lead The following description takes America standards as examples.
NOTE: The following table gives the corresponding lead names used in Europe and
America Standards. (Lead name is represented by R, L, N, F, C respectively in
Europe Standard, while corresponding lead name in America Standard is RA, LA, RL, LL, V.)

NOTE: To ensure patient safety, all leads must be attached to the patient. Recommended ECG Lead Placement for Surgical Patients
The placing of the ECG leads will depend on the type of surgery that is being performed. For example, with open chest surgery the electrodes may be placed laterally on the chest or on the back. In the operating room, artifacts can sometimes affect the ECG waveform due to the use of ES (Electrosurgery) equipment. To help reduce this you can place the electrodes on the right and left shoulders, the right and left sides near the stomach, and the chest lead on the left side of mid-chest. Avoid placing the electrodes on the upper arms, otherwise the ECG waveform will be too small.
WARNING
When using electrosurgery equipment, leads should be placed in a position in
equal distance from electrotome and the grounding plate to avoid cauter y. Electrosurgery equipment wire and ECG cable must not be tangled up.
When using Electrosurgery equipment, never place an electrode near the
grounding of the electrosurgery device, otherwise there will be a great interference with the ECG signal.
When the monitor is connected to a defibrillator and other high-frequency
devices, it is recommended to use anti-defibrillation ECG leads, otherwise it may cause burns to the patient.
When the monitor is used with a defibrillator, the operator should avoid
contact with the patient or bed, and the defibrillation electrode should not touch the electrode of the monitor directly, for doing so may generate sparks

then causing device damage or patient injury.
NOTE: If a ECG waveform is not accurate, while the electrodes are correctly attached,
try to change the lead.
Interference from a non-grounded instrument near the patient and ESU
interference can cause inaccuracy of the waveform.
A good signal should be:
Tall and narrow with no notches. With tall R-wave completely above or below the baseline. With pacemaker signal no higher than R-wave height. With T-wave less than one-third of the R-wave height. With P-wave much smaller than the T-wave.
To obtain a 1 mv calibrated ECG wave, the ECG should be calibrated. A message "when CAL, can't monitor!" prompts on the screen.

ECG Hot Key
Leads of channel 1:
1) The selectable leads are I, II, III, aVR, aVL, a V F, V.
2) When the ECG is 5-lead, the selectable leads are: I, II, III, aVR, aVL, aVF; V. When ECG is 3-lead, the selectable leads are: I, II, III.
3) Leads on the ECG waveform must not use the same name. Otherwise, the system will automatically change the ECG waveform name that has been used to another one.
Waveform gain of channel 1: to adjust the amplitude of ECG waveforms
Select gain value for each channel from ×0.25, ×0.5, ×1, ×2 and ×4. A 1mV scale displays on each ECG channel's one side. The height of the scale is directly proportional to the waveform amplitude.
Filter method: to display clearer and more detailed waveform
There are three filter modes for selection. In DIAGNOSTIC mode, the ECG waveform is displayed without filter. In MONITOR mode, the artifact that may cause false alarm is filtered. And the SURGERY mode could reduce artifacts and interferences from electrosurgery equipment. The filter mode is applicable for both channels, and it is displayed at the top of screen.
④ Leads of channel 2: refer to ① for detailed information. ⑤ Waveform gain of channel 2: refer to ② for detailed information.
Page 73
64
WARNING
Only in Diagnostic mode, the system can provide non-processed real signals.
In Monitor or Surgery mode, ECG waveforms may have distortion of different extent. In either of the latter two modes, the system can only show the basic ECG, the results of ST analysis may also be greatly affected. In Surgery mode, results of ARR analysis may be somewhat affected. Therefore, it is suggested that in the environment having relative small interference, you’d better monitor a patient in Diagnostic mode.
NOTE: When the input signals are too large, the peak of the waveform may not able
to be displayed. In this case user could manually change the gain setup of ECG waveform according to the actual waveform so as to avoid the occurrence of the unfavorable phenomena.

10.8 ARR Monitoring Arrhythmia analysis

The arrhythmia analysis is used to monitor ECG of neonate and adult patient in clinical, detect the changing of heart rate and ventricular rhythm, and also save arrhythmia events and generate alarming information. Arrhythmia analysis can monitor the patient with or without pacemaker. Qualified personnel can use arrhythmia analysis to evaluate patient’s condition (such as heart rate, PVCs frequency, rhythm and abnormal heartbeat) and decide the treatment accordingly.
Page 80
71
Besides detecting the changing of ECG, arrhythmia analysis can also monitor patients and give proper alarm for arrhythmia.
The arrhythmia monitoring is shutoff by default. You can enable it when
necessary.
This function can call up the doctor's attention to the patient's heart rate
by measuring and classifying the arrhythmia and abnormal heart beat, and triggering the alarm.
The monitor can conduct up to 13 different arrhythmia analysis. The monitor can store the latest 60 alarm events (a single-channel ECG
waveform 4 seconds before and after the alarm) during the arrhythmia analysis process. The operator can edit these arrhythmia events through this menu.

Chapter 11 RESP Monitoring

11.1 Introduction

Measurement method: chest impedance. When the patient breathes, the thoracic activity causes a change in the thoracic impedance between the two ECG electrodes. The monitor produces a respiratory wave on the screen by measuring the impedance change (due to the movement of the thorax), then it calculates the respiration rate based on the waveform cycle.

11.2 Safety information

WARNING
Respiratory measurement does not recognize the reason of suffocation, it will
only give alarm if no next respiration is checked within the predetermined time after the last breath, so it can not be used for diagnostic purposes.

11.3 Placement for RESP electrode

Since the same leads are used for ECG and respiration monitoring, the lead placement is very important. Some patients, due to their clinical condition, expand their chest laterally, causing a negative intrathoracic pressure. In these cases it is better to place the two crocodile clips used for respiration monitoring laterally in the right axillary and left lateral chest areas, at the maximum point of the breathing movement, to optimize the respiratory waveform.
Electrodes Placement
NOTE:

e
The RESP monitoring is not recommended to be used on patients who are
very active, as this can cause false alarms.
Placing the red and white electrodes diagonally to obtain the optimal
respiration waveform. Avoid the liver area and the ventricles of the heart in the line between the RESP electrodes so as to avoid cardiac overlay or artifacts from pulsating blood flow. This is particularly important for neonates.

Chapter 12 SpO2 Monitoring

12.1 Introduction

SpO
Plethysmogram measurement is employed to determine the oxygen saturation
2
of hemoglobin in the arterial blood. If, for example, 97% hemoglobin molecules in the red blood cells of the arterial blood combine with oxygen, then the blood has a SpO
oxygen saturation of 97%. The SpO2 numeric on the monitor will read 97%. The
2
SpO
numeric shows the percentage of hemoglobin molecules which have combined
2
with oxygen molecules to form oxyhemoglobin. The SpO
/PLETH parameter can also
2
provide a pulse rate signal and a plethysmogram wave.
How the SpO
/ PLETH Parameter Works
2
Arterial oxygen saturation is measured by a method called pulse oximeter. It is
a continuous, non-invasive method based on the different absorption spectra of reduced hemoglobin and oxyhemoglobin. It measures how much light, sent from light sources on one side of the sensor, is transmitted through patient tissue , to a receiver on the other side.The sensor measurement wavelengths are nominally 660nm for the Red LED and 880nm for Infrared LED. Maximum optical power output for the Red LED is 6.65 mW and the Infrared LED is 6.75 mW. Optical sensors as the light-emitting components, will bring influence to other medical devices applied the wavelength range. This information may be useful for clinicians who carry out optical therapy.
The amount of light transmitted depends on many factors, most of which are
constant. However, one of these factors, the blood flow in the arteries, varies with time, because it is pulsating. By measuring the light absorption during a pulsation, it is possible to get the oxygen saturation of the arterial blood. Detecting the pulsation gives a PLETH waveform and pulse rate signal.
The SpO
value and the PLETH waveform can be displayed on the main screen.

12.2 Safety information

WARNING
Only the SpO
sensor specified in this manual can be used, please use it
2
following the Use Manual, and obey all warnings and precautions.
Check if the sensor cable is in normal condition before monitoring. After

cable must not be tangled up.
2
Prolonged and continuous monitoring may increase the risk of unexpected
change of skin condition such as abnormal sensitivity, rubescence, vesicle, repressive putrescence, and so on. It is especially important to check the sensor placement of patient of poor perfusion or immature dermogram by

function is calibrated to show functional oxygen saturation.
2
The PLETH waveforms are not normalized, so the accuracy of the measured
values may decrease when the waveform does not tend to be smooth and stable. When the waveform tends to be smooth and stable, the measured value is the best value, and the waveform is the most standard.
The update time of measurement data is less than 10 seconds, which depends
on the PR value. Data averaging and other signal processing have no effect on SpO
displaying and data values transmitted.

resonance imaging (MRI) scanning, as the induced current may cause burns.

12.5 Measurement Limitations During measuring, the measurement accuracy can be affected by:

High-frequency electrical interference, such as the interference created by the
host system, or interference from external sources, for example electrosurgical apparatus connected to the system.
Diagnostic test. Electrosurgery unit. Intravascular dye injections Electromagnetic field effects, such as nuclear magnetic resonance equipment. Excessive patient movement(patient moves actively or passively). Improper sensor installation or incorrect contact position of the patient Place the sensor on an extremity that has a blood pressure cuff, arterial
catheter, or intravascular line.
Significant concentrations of non-functional hemoglobin, such as
carboxyhemoglobin(COHb) and methemoglobin(MetHb).
Bad circular perfusion of the part being measured For some special patients, it should be a more prudent inspecting in the
measurement part. The sensor can not be clipped on the edema and tender tissue.
When the device is carried from cold environment to warm or humid
environment, please do not use it immediately.
Make sure the optical path is free from any optical obstacles like rubberized
fabric, to avoid inaccurate measurement.
Excessive ambient light may affect the measurement result. It includes
fluorescent lamp, dual ruby light, infrared heater, direct sunlight, etc.

Chapter 13 NIBP Monitoring

13.1 Introduction

Measurement method: Oscillometry. It is applicable for adult, pediatric and neonate. In order to know how the Oscillometry works, we compare it with auscultatory method: Auscultatory method: the doctor listens the blood pressure by the stethoscope,
to obtain the systolic pressure and diastolic pressure. When the artery pressure
curve is normal, the mean pressure can be calculated by the systolic pressure
and diastolic pressure. Oscillometry: the blood pressure can not be listened by the monitor, it
measures the vibration amplitude of cuff pressure. Cuff vibration appears when
the blood pressure changes, the cuff pressure corresponding to the maximum
amplitude is the mean pressure, the systolic and diastolic pressure can be
calculated by the mean pressure. In a word, the auscultatory method measures the systolic and diastolic pressure, then calculates the mean pressure. And the Oscillometry measures the mean pressure, then calculates systolic and diastolic pressure. The clinical meaning for NIBP measurement must be determined by the physician. When measuring during in representative patients group, compare the blood pressure values measured by the device and auscultatory method, its accuracy meets the requirements specified in IEC 80601-2-30:2009.

13.2 Safety information

WARNING
Before measuring, make sure that the monitoring mode and cuff type you
selected are appropriate for your patient(cat, dog or other animals). As false
settings may imperil patient's safety, higher adult settings are not suitable for
pediatric and neonate.
The animal on which the NIBP measurement is done must be no lessthan 2kg. You must not perform NIBP measurement on patients with sickle-cell disease
or under any condition which the skin is damaged or expected to be
damaged. Do not apply the cuff to a limb that has an intravenous infusion or catheter.
This could cause tissue damage around the catheter when infusion is slowed
or blocked during cuff inflation. NIBP measurement can be performed during electrosurgery and defibrillator
discharge, as the device has the function of protecting burn patients. The device can be used in existence of electrosurgical equipment, but when
using them together, user(doctor or nurse) should guarantee the patient's
safety. Make sure that the air conduit connecting the blood pressure cuff and the
Page 95
86
monitor is neither blocked nor tangled. The width of the cuff should be either 40% of the limb circumference or 2/3
of the upper arm length. The inflatable part of the cuff should be long
enough to circle 50-80% of the limb. The wrong size cuff can cause erroneous
readings. If the cuff size is in question, use a larger cuff. If liquid is inadvertently splashed on the device or its accessories, or may
enter the conduit or inside the monitor, please contact with the maintenance
department in hospital.
NOTE: If you are in doubt about the accuracy of any reading(s), check the patient's
vital signs by an alternative method before checking the functioning of the
monitor. When the alarm prompt information for low battery appears, it is not
recommended to start NIBP measurement. As in this circumstance, it may
cause device shutdown.

13.3 Measurement Limitations

NIBP measurement can not be done on the patients with extreme heart rate(lower than 40 bpm or higher than 240 bpm) or connecting with heart-lung machine. The measurement may be inaccurate or can not be done in the following conditions: Patient Movement Measurement will be unreliable or may be impossible if the patient is moving, shivering or having convulsions. As these conditions may interfere the detection of the arterial pressure pulsation, and the measurement time will be prolonged. Cardiac Arrhythmia's Measurement will be unreliable and may be impossible if the patient has irregular heartbeat arisen from cardiac arrhythmia, and the measurement time will be prolonged. Heart-lung Machine Measurements will not be possible if the patient is connected to a heart-lung machine. Pressure Change Measurement will be unreliable and may be impossible if the patient's blood pressure is changing rapidly over the period of time during which the arterial pressure pulsation are being analyzed to obtain the measurement values. Severe Shock If the patient is in severe shock or hypothermia, measurements will be unreliable since the decrease for the blood flowed to the peripheries will cause the reduction of artery pulsation. Fat patient The thick fat layer under the limb will decrease the measurement accuracy, as the vibration from artery can not arrive to the cuff which is arisen from the fat damping.

13.4 Measurement steps

1. Confirm the patient type, if it is false, please change "Patient type" in "PATIENT
SETUP" of "SYSTEM MENU".
2. Connect the airway tube with the NIBP interface of the device, then switch on
thedevice.
3. Select the cuff, make sure the cuff is completely deflated, then apply the cuff to
the patient's arm or leg following the instructions below.
Confirm the limb perimeter of the patient.  Fo r a CAT
For conscious patients, measurements from the coccygeal artery can be taken by wrapping the cuff around the base of the tail. For anesthetized patients,measurements from the median artery on the foreleg can be used by wrapping the cuff around the forelimb, between the elbow and carpus. For cats less than five pounds when measurements are difficult to obtain, place the cuff around the leg above the elbow to obtain measurements from the brachial artery. Hair need not be clipped except when heavily matted.
Cat Cuff Placement
For a DOG For measurements in dogs, it is preferable to use the right lateral, stemal or dorsal recumbent position. If the dog is in a sitting position, place the front paw on the operator’s knee and take measurements from the metacarpus. The metacarpus, metatarsus and anterior tibial are recommended for the cuff placement. For anesthetized patients, most surgeries are done on the posterior part of the body so the metacarpal area of the forelimb is most convenient. In situations where this is not possible, place the cuff around the metatarsus just proximal to the tarsal pad or around the hind leg next to the hock. For conscious patients, measurements from the coccygeal artery can be used over the tail site.
Page 97
88
Dog Cuff Placement
For larger animals It is preferable for a large animal, such as a horse and a cow, to be in a stock, standing still. Measurments from the coccygeal artery on the ventral surface may be used by placing the cuff around the base of the tail.
4. Connect the cuff to the airway tube. Make sure that the airway tube is neither
blocked nor
tangled.
5. Select a measurement mode in "NIBP SETUP" interface. Refer to the following
paragraphs "Operation Hints" for Details
6. Press "STA RT" button on the front panel to start a measurement.
NOTE:
The limb chosen for taking the measurement should be placed at the same
level as the patient's heart If the animal’s hair over the artery site is too thick or matted for good contact,
it should be clipped. The width of the cuff should be either 40% of the limb circumference (50% for
neonates) or 2/3 of the upper arm length. The inflatable part of the cuff
should be long enough to encircle 50-80% of the limb. The wrong size of cuff
can cause erroneous readings. If the cuff size is in question, then use a larger
cuff.

13.5 Operation hints

1. Manual operation Select "MANUAL" in "INTERVAL" item of "NIBP SETUP" interface, then press
"START" button on the front panel to start a manual measurement. During the idle time of auto measuring process, press "STAR T" button on the
front panel to start a manual measurement. Press "STA RT" button again to stop
manual measurement and the system continues auto measuring.
2. Auto measuring Select a interval value in "INTERVAL" item of "NIBP SETUP" interface to perform auto measurement., then press "START" button on the front panel to start the first measurement, after finishing, the system will automatically measure according to the interval time.

3. Continuous measuring Select "CONTINUAL" item in "NIBP SETUP" interface to start a continuous measurement. The precess will continue 5 minutes.
4. Stop measuring During measuring, press "START" button on the front panel to stop measuring.
WARNING
In auto or continuous mode, if the time is too long, then the limb rubbed with
the cuff may appear purpura, ischemia and nerve injury. So when monitoring
the patient, patient's limb color, warmth and sensitivity should be checked
frequently. Once any abnormality appears, please replace the cuff location or
stop the NIBP measurement.

13.6 Amend results

Keep the limb to be measured and the patient's heart on one horizontal position. Otherwise amend the measurement results by the following methods: If the cuff is higher than the horizontal position of the heart, then the value
should add 0.75 mmHg(0.10 kPa) after the displayed value. If the cuff is lower than the horizontal position of the heart, then the value
should subtract 0.75 mmHg(0.10 kPa) after the displayed value.

13.7 NIBP display

There is no waveform for NIBP measurement, it only displays the NIBP measurement results. The following figure is only used for reference, your device may display a different interface.

in the above table. Move the cursor to the "Inflation" item and press it, inflation value range(as shown in the above table) in MANUAL mode can be seen.
NOTE: "Inflation" is used to help user select the cuff inflation pressure next time, but
the subsequent inflation is the measurement value of last systolic pressure
based on the same patient. The system momorizes the value, which can
shorten the measurement time of the same patient and increase the
measurement accuracy. If user only sets the "Patient type" in "PATIENT SETUP" interface, does not
perform any selection in "DEFAULT", the system will operate according to the
initial setting of relative module parameter in "Patient type". The change of
default type setting in "DEFAULT" will alter the "Patient type" in "PATIENT
SETUP" interface.
