CARDELL MONITOR SERVICE MANUAL
1. INTRODUCTION AND INTENDED USE
INTRODUCTION
The CARDELL Veterinary Monitors, Models 9401 and 9402, are vital signs monitors measuring
blood pressure and oxygen saturation. The monitors are restricted for use, one patient at a
time. Non-invasive blood pressure is measured using the oscillometric technique determining
systolic, diastolic, mean arterial pressure and pulse rate. The pulse oximeter function
continuously monitors and displays values for functional arterial hemoglobin saturation and a
pulse rate.
BRIEF DEVICE DESCRIPTION
The CARDELL Monitor is compact, lightweight and portable, allowing it to be easily carried and
used in a variety of clinical settings. The monitor is powered by AC Line Power or by a Nickel
Metal Hydride (NiMH) rechargeable battery pack. The internal battery pack charges when the
monitor is plugged into the AC wall outlet. The CARDELL Monitor can be set to operate in one
(1) of nine (9) different languages: English, German, French, Italian, Spanish, Dutch, Swedish,
Portuguese or Norwegian. The message window can display various system alarm messages.
These messages direct the user to check conditions such as the battery state, air leaks and
measurement problems. The message window also displays the operational mode of the
monitor (automatic or manual).
The non-invasive blood pressure (NIBP) parameter automatically inflates an occluding cuff and,
using the oscillometric measurement technique, determines systolic, diastolic and mean arterial
pressure and pulse rate. Measurement results along with operator prompts and error messages
are displayed on the front panel. The frequency of NIBP determination can be selected by the
operator in varied times between one and ninety minutes. The auto and manual operating
modes cover a variety of clinical uses.
The pulse oximeter parameter (%SpO2) determines arterial oxyhemoglobin saturation by
measuring the absorption of red and infrared light passing through the tissue. Changes in
absorption caused by pulsations of blood in the vascular bed are used to determine arterial
saturation and pulse rate. The oximeter requires no routine calibration or maintenance.
Oxygen saturation and heart rate are displayed on light emitting diode (LED) digital displays.
On each detected pulse, the perfusion LED does indicate patient perfusion signals. This bar
graph gives the user a pulse-by-pulse visual indication of waveform signal quality. An audio
“beep” can be enabled that is generated each time the SpO2 module detects a pulse.
NOTE:
The bar graph is not proportional to the pulse volume.

3. SAFETY MEASURES AND WARNINGS
WARNING:
The CARDELL MODEL 9401 and 9402 monitors are intended for VETERINARY USE ONLY.
Do no use on human patient.
Do not use this instrument for any purpose other than specified in this manual. Doing so will
invalidate the monitor’s warranty.
Do not connect more than one (1) patient to the monitor.
Do not plug the monitor into an outlet controlled by a wall switch.
The position of subject, physiological condition, and other factors affect the readings.
Blood pressure and pulse can fluctuate greatly between measurements; the monitor cannot
alert the user to changes in vital signs occurring between measurement cycles.
Occasionally, electrical signals at the heart do not produce a peripheral pulse. If a patient’s
beat-to-beat pulse amplitude varies significantly (for example, pulsus alternans, atrial fibrillation,
rapid-cycling artificial ventilator), blood pressure and pulse rate readings can be erratic and an
alternate measuring method should be used for confirmation.
Where the integrity of the external protective conductor in the installation or its arrangement is in
doubt, EQUIPMENT shall be operated from its INTERNAL ELECTRICAL POWER SOURCE.
Isolation of product from mains can only be achieved by removal of external power cord.
Do not, under any circumstances, perform any testing or maintenance on the monitor or power
cord while the unit is being used to monitor a patient. Unplug the power cord before cleaning or
servicing the monitor. The operator should not perform any servicing except as specifically
stated in this manual.
Do not touch part of non-medical electrical equipment in the patient environment after removal
of covers, connectors etc… without the use of a tool which operate at voltages not exceeding 25
VAC or 60 VDC and the patient at the same time.
Do not use a frayed or damaged power cord, or any accessory if you notice any sign of
damage. Contact Midmark for assistance.
Equipment not suitable for use in the presence of a FLAMMABLE ANESTHETICS.
Equipment is not intended to be used in Oxygen Enriched Atmospheres.
Do not gas sterilize or autoclave the monitor.
Do not use the monitor in the presence of Magnetic Resonance Imaging (MRI) equipment.

CARDELL MONITOR SERVICE MANUAL
WARNING:
Do not apply the blood pressure cuff on an extremity being used for an intravenous infusion.
Do not place liquids on top of the monitor. Do not immerse the monitor or power cord in water
or any liquid. If unit is accidentally wetted it should be thoroughly dried. The rear cover can be
removed by a qualified service technician to verify absence of water.
Accurate oxygen saturation measurement cannot be obtained with the Model 9402 when the
oximeter is not measuring the pulse properly. If the perfusion bar graph or the PULSE RATE be
erratic or inaccurate, first examine the animal for any signs of distress and only then re-examine
sensor placement.
Inadequate perfusion, thick fur, dark skin or foreign matter that blocks light or an improperly
applied sensor can result in erratic and inaccurate oxygen saturation and/or pulse rate
measurement. Should the perfusion bar graph be at a low level, reposition the sensor or try a
different sensor. If proper operation cannot be verified, remove the sensor from the animal and
do not use the oximeter on this animal.
In the event the sensor becomes dislodged from the animal, audible and visual alarms are
activated requiring that a veterinary professional investigate the reason for the alarm status.
The veterinary professional should investigate status and sensor attachment after every sensor
alarm indication. It is possible when the sensor is dislodged from the animal (under certain
conditions of light and vibration of the sensor) for the pulse oximeter to display normal
physiological values.
ACCURACY – If the accuracy of any measurement does not seem reasonable, first check the
patient’s vital signs by alternate means and then check the CARDELL Monitor for proper
functioning.
CABLES – Route all cables away from patient’s throat to avoid possible strangulation.
DEFIBRILLATION – Do not come in contact with patients during defibrillation. Serious injury or
death could result.
DISPOSAL – Dispose of the packaging material, observing the applicable waste control
regulations.
LEAKAGE CURRENT TEST – The interconnection of auxiliary equipment with this device may
increase the total leakage current. When interfacing with other equipment, a test for leakage
current must be performed by a qualified biomedical engineering personnel before using with
patients. Serious injury or death could result if the leakage current exceeds applicable
standards. The use of accessory equipment not complying with the equivalent safety
requirements of this equipment may lead to a reduced level of safety of the resulting system.
Consideration relating to the choice shall include: use of the accessory in the patient vicinity;
and evidence that the safety certification of the accessory has been performed in accordance
with the appropriate IEC 601.1 and/or IEC 601.1.1 harmonized national standard.
SITE REQUIREMENTS – For safety reasons, all connectors for patient cables and sensor leads
are designed to prevent inadvertent disconnection, should someone pull on them. Do not route
cables in a way that they may present a stumbling hazard. For devices installed above the
patient, adequate precautions must be taken to prevent them from dropping on the patient.

CARDELL MONITOR SERVICE MANUAL
CAUTION:
Before each use, make sure that the monitor default alarm settings are appropriate for the
specific patient being monitored.
Pressing the front panel keyswitch with a sharp or pointed instrument may permanently damage
the keyswitch. Press the keyswitch using only your finger.
As with any non-invasive oscillometric blood pressure monitor, the accuracy of the
measurements obtained may be adversely affected by the presence of agents which alter the
patient’s cardiovascular system.
A calibration check is recommended once every year.
Do not alter the monitor's air hose. CAS Medical Systems cannot ensure proper monitor
performance if the tubing is altered. Modification of the air hose will void the warranty. Avoid
compression or restriction of pressure tubes.
If the cuff is applied on a limb being used for oxygen saturation monitoring %SpO2 results will be
altered during each blood pressure measurement due to the occlusion of blood flow.
Inspect the monitor, air hose and sensors for any damage prior to operation. If any damage is
noted, the monitor should not be used until it has been serviced. The monitor should be
repaired only by personnel authorized to do so by CAS Medical Systems, Inc.
Use only CAS Medical Systems approved accessories and sensors to preserve the integrity,
accuracy and the electromagnetic compatibility of the monitor.
Consult a veterinarian for interpretation of blood pressure measurements.
The oximeter is factory calibrated to determine the percentage of arterial oxygen saturation of
functional hemoglobin.
Significant levels of dysfunctional hemoglobins such as carboxyhemoglobin or methemoglobin
may affect the accuracy of the measurement.
Cardiogreen and other intravascular dyes, depending on the concentration, may affect the
accuracy of the oximeter measurement.
Some sensors may not be appropriate for a particular patient. If at least ten seconds of one bar
pulses cannot be observed for a given sensor, change sensor location until this condition is
achieved.
If the monitor fails to respond, do not use it until the situation has been corrected by qualified
personnel.

CARDELL MONITOR SERVICE MANUAL
CAUTION:
ACCIDENTAL SPILLS – In the event that fluids are accidentally spilled on the monitor, take the
monitor out of operation and inspect for damage.
BATTERY POWER – If the monitor will not be used or not connected to AC line power for a
period over six (6) months, remove the battery.
ELECTRICAL SHOCK – To reduce the risk of electrical shock, do not remove the back cover.
Refer all servicing to qualified personnel.
ELECTROMAGNETIC COMPATIBILITY (EMC) – The equipment needs special precautions
regarding EMC. Be aware that strong electromagnetic fields may interfere with monitor
operation. Interference prevents the clear reception of signals by the monitor. If the hospital is
close to a strong transmitter such as TV, AM, or FM radio, police or fire stations, a HAM radio
operator, an airport, or cellular phone, their signals could be picked up as signals by the
monitor. If you feel interference is affecting the monitor, contact your CAS Medical Systems
representative to check the monitor in your environment.
ELECTROSURGERY – Measurements may be affected in the presence of strong
electromagnetic sources such as electro surgery equipment.
GROUNDING – Do not defeat the three-wire grounding feature of the power cord by means of
adaptors, plug modifications, or other methods. Do not use extension cords of any type. Do not
connect the monitor to an electrical outlet controlled by a wall switch or dimmer.
INTERFACING OTHER EQUIPMENT – Monitoring equipment must be interfaced with other
types of medical equipment by qualified biomedical engineering personnel. Be certain to
consult manufacturers’ specifications to maintain safe operation.
STACKING – Where monitor is used adjacent to or stacked with other equipment, the monitor
should be observed to verify normal operation in the configuration in which it will be used.

device failure during or after exposure.
AUTOMATIC SAFETY FEATURES
The monitor has been designed for patient safety. The maximum amount of time allowed to
complete a blood pressure measurement is 150 seconds. If the measurement has not been
completed within that time, the cuff is deflated automatically and a message is displayed
indicating the problem.
To prevent exposure of the extremity to an inordinately high pressure, the cuff is deflated
automatically when the pressure in the system is greater than 290 mmHg.
In the event of a microprocessor failure, the cuff will be deflated automatically within ten (10)
seconds.
All equipment parts are protected against the effects of the discharge of a defibrillator. No
separate actions are required when using this equipment with a defibrillator.
Should the AC power be interrupted coming into the monitor, the monitor automatically runs off
battery power. An indication of this would be a change in color of the Battery Charge LED from
Green to either Orange or Red.
Whenever the power is disconnected from the monitor and the monitor is not allowed to shut
down in an orderly fashion, the monitor, when re-powered alerts the user.
CAUTION:
Regardless of these safety features, always be sure to check that there are no signs of
prolonged impairment of patient circulation and that the monitor is functioning properly.
