General warnings and cautions

WARNING Many environmental variables, including patient physiology and
clinical application, can affect the accuracy and performance of the monitor. The
clinician must verify all vital signs information before treating the patient. If there is
any question about the accuracy of a measurement, verify the measurement using
another clinically accepted method.

WARNING Alarm limits are patient- or facility-specific. The clinician must set or
verify alarm limits appropriate for each patient. Each time the monitor is powered
on, you must check that the alarm settings are appropriate for your patient before
you start monitoring.

WARNING Use only Welch Allyn approved accessories, and use them according
to the manufacturer’s directions for use. Using unapproved accessories with the
monitor can affect patient and operator safety and can compromise product
performance and accuracy.

Directions for use About warnings and cautions 11

WARNING Inaccurate measurement risk. Do not use the monitor on patients who
are experiencing convulsions or tremors.

WARNING Do not place the monitor in any position that might cause it to fall on
the patient.

WARNING Welch Allyn is not responsible for the integrity of a facility's power. If
the integrity of a facility's power or protective earth conductor is in doubt, always
operate the monitor on battery power alone when it is attached to a patient.

WARNING For operator and patient safety, peripheral equipment and
accessories that can come in direct patient contact must comply with all applicable
safety, EMC, and regulatory requirements.

WARNING All signal input and output (I/O) connectors are intended for
connection of only devices complying with IEC 60601-1, or other IEC standards (for
example, IEC 60950), as applicable to the monitor. Connecting additional devices to
the monitor may increase chassis or patient leakage currents. To maintain operator
and patient safety, consider the requirements of IEC 60601-1-1. Measure the
leakage currents to confirm that no electric shock hazard exists.

WARNING Equipment failure and patient harm risk. Do not cover the air intake
vents on the right or exhaust vents on the front of the Connex IWS. Covering these
vents could cause overheating or muffling of alarms.

WARNING This equipment is not suitable for use in the presence of electro­surgery.

WARNING Cross-contamination or nosocomial infection risk. Clean and disinfect
the monitor on a routine basis according to your facility's protocols and standards
or local regulations. Thorough hand-washing before and after contact with patients
greatly reduces the risk of cross-contamination and nosocomial infection.

WARNING The physical assessment instruments (handles) are designed for
intermittent use. On-time should not exceed 2 minutes. Allow at least 10 minutes off­time between patients.

CAUTION United States Federal law restricts this monitor to sale, distribution, or

Nurse call

The monitor can be connected to a Nurse Call system through a cable that connects to the Nurse
Call connector.

When the Nurse Call cable is connected and Nurse Call is enabled, the monitor immediately
notifies the Nurse Call system when a physiological alarm that exceeds the preset threshold
occurs. The Nurse Call system is also synchronized with the flashing LED lightbar and audible
alerts on the monitor.

Nurse Call thresholds are set in the Advanced Settings.

To connect the monitor to a Nurse Call system, you must have a cable that has been adapted to
your Nurse Call system (REF 6000-NC), rated 25V AC or 60V DC maximum at 1A maximum. For
ordering information, see Approved Accessories in the Appendix.

WARNING Do not rely exclusively on Nurse Call for patient monitoring. Although
the Nurse Call option enables remote notification of an alarm condition, it is not
intended to replace appropriate bedside patient monitoring by trained clinicians.

Note When a patient alarm occurs, touching the alarm icon in the Device Status area

pauses the alarm tone for a period ranging from 90 seconds to 15 minutes, as
specified in Advanced settings, but the visual alarm indicator(s) on the monitor and

Directions for use Patient monitoring 71

WARNING Never use an adult or pediatric monitor setting or cuff for an NIBP
measurement on a neonatal patient. Adult and pediatric inflation limits can be
excessive for neonatal patients, even if a neonatal cuff is used. Neonates are
defined in the AAMI SP10:2002 standard as children 28 days or less of age if born at
term (37 weeks gestation or more); otherwise, up to 44 gestational weeks.

CAUTION Correct sizing of the blood pressure cuff is important for accurate
blood pressure readings. A cuff that is too small might provide false high readings,
while a cuff that is too large might provide false low readings.

The monitor uses the oscillometric method to determine blood pressure; therefore, if the cuff
extends to the antecubital fossa (bend in the elbow), you can still acquire an accurate blood
pressure reading.

Before taking an NIBP measurement, follow these steps to select the appropriate cuff for the
patient.

Measure the circumference of the patient's bare upper arm, midway between the elbow and

1.
shoulder.

2. Choose the appropriate cuff size based on the circumference measurement. If the
circumference of the patient's arm falls between two cuff sizes, use the larger cuff size.

3. Wrap the cuff around the patient's bare upper arm and verify that the artery index marker lies
somewhere between the two range markings on the cuff.

Position the cuff

Note The monitor and cuffs were validated using the bare upper arm site.

WARNING Patient injury risk. Do not use the NIBP for continuous monitoring

without frequently checking the patient's limb. When a patient is being monitored
frequently or for a prolonged period, regularly remove the cuff to inspect it and to
check the cuff site for ischemia, purpura, or neuropathy.

WARNING Inaccurate measurement risk. Do not place the cuff where it can
disturb proper circulation. Do not place the cuff on any area where circulation is
compromised or on any extremity used for intravenous infusions. Do not use an
SpO2 finger clip sensor and a blood pressure cuff simultaneously on the same limb.
Doing so may cause a temporary loss of pulsatile flow, resulting in either no reading
or an inaccurate SpO2 or pulse rate until the flow returns.

WARNING The blood pressure cuff must be properly positioned to ensure blood
pressure accuracy and patient safety. Wrapping the cuff too loosely (preventing
proper inflation) may result in inaccurate NIBP readings.

CAUTION If a site other than the bare upper arm is used, the blood pressure
measurements may be different. It is important to document the alternate site on the
patient record.

CAUTION To minimize inaccurate measurement, limit patient movement during
an NIBP measurement cycle.

Before taking an NIBP measurement, follow these steps to properly attach the cuff to the patient.

Position the cuff on the patient's bare upper arm midway between the shoulder and the elbow.

1.

2. Wrap the cuff snugly so that there is room for no more than two fingers between the cuff and
the patient's bare upper arm.

3. Position the alignment mark on the cuff directly over the brachial artery.

4. Ensure that the blood pressure tubing has no kinks or twists.

Note In situations where you cannot position the cuff level with the heart,

you should adjust the measurements as follows for greater
accuracy. For each inch (2.54 cm) that the cuff is above the level of
the heart, add 1.8 mmHg to the displayed reading. For each inch
(2.54 cm) that the cuff is below the level of the heart, subtract 1.8
mmHg from the displayed reading. It is important to document the
adjustment on the patient record.

Directions for use Patient monitoring 73

NIBP measurement

The monitor enables you to take manual and automatic NIBP measurements.

WARNING NIBP readings may be inaccurate for patients experiencing moderate
to severe arrhythmia.

WARNING Do not allow a blood pressure cuff to remain on neonatal patients
more than 90 seconds when inflated above 5 mmHg. Do not allow a blood pressure
cuff to remain on the adult patients more than 3 minutes when inflated above 15
mmHg. Excessive cuff tightness may cause venous congestion, peripheral nerve
injury, discoloration of the limb, and patient distress.

WARNING Inaccurate measurement risk. Pulse rate measurements generated
through the blood pressure cuff or through SpO2 are subject to artifact and might
not be as accurate as heart rate measurements generated through ECG or through
manual palpation.

WARNING Use caution when measuring blood pressure using oscillometric
blood pressure devices in severely ill neonates and pre-term infants because these
devices tend to measure high in this patient population.

CAUTION Inaccurate measurement risk. Any external compression of the blood
pressure hose or cuff may cause system errors or inaccurate measurements.

At the start of a measurement, the monitor inflates the cuff to the appropriate level. In the NIBP
frame, the systolic display shows the cuff inflation pressure while the blood pressure measurement
is in progress.

The monitor measures blood pressure as the cuff is inflating. If patient movement, excessive noise,
or an arrhythmia prevent the monitor from determining the blood pressure while the cuff is
inflating, the monitor attempts to measure the blood pressure while deflating the cuff.

When the measurement is complete, the NIBP frame displays the measurement until you save it to
the patient's record or you start another NIBP measurement.

Note The Pediatric and Adult blood pressure modes are supported on patients 29 days

and older. The Pediatric mode gives you the option of setting a lower initial inflation
pressure when using the StepBP deflation and not SureBP.

Note Use dual-lumen tubes for adult and pediatric blood pressure measurements and

single-lumen tubes for neonate blood pressure measurements. Mismatching tube
types, patient types, and algorithms causes an information message to appear in
the Device Status area. For neonate patients, set the NIBP settings as follows:
Patient = Neonate, Tube type = 1 tube, Algorithm = Step.

Note Welch Allyn uses the following definition of Neonate: Children 28 days or less of age

if born at term (37 gestation or more); otherwise, up to 44 gestational weeks.

Take a manual NIBP measurement

WARNING Patient injury risk. Never install Luer Lock connectors on Welch Allyn

blood pressure cuff tubing. Using these connectors on blood pressure cuff tubing
creates the risk of mistakenly connecting this tubing to a patient's intravenous line
and introducing air into the patient's circulatory system.

CAUTION Inaccurate measurement risk. Any external compression of the blood
pressure hose or cuff may cause system errors or inaccurate measurements.

SureTemp® Plus temperature module

The temperature module uses a thermistor thermometer design and a predictive algorithm to
calculate patient temperatures in the Predictive mode.

WARNING Patient injury risk. Prior to taking a temperature, instruct the patient
not to bite down on the probe as patient injury and damage to the probe may result.

WARNING Patient injury risk. Do not exceed the recommended temperature
measurement durations in Direct mode. Continuous measurement durations of 3
minutes at the oral and rectal sites and 5 minutes at the axillary site are
recommended for accurate measurement. Do not continuously measure beyond 10
minutes in any mode.

WARNING Probe covers are single-use only. Re-use of a probe cover may result
in spread of bacteria and cross-contamination.

WARNING Patient injury risk. Use only Welch Allyn single-use disposable probe
covers. Never take a temperature measurement without a single-use probe cover
securely attached. Failure to use a probe cover can cause patient discomfort from a
heated probe, patient cross-contamination, and inaccurate temperature readings.

80 Patient monitoring Welch Allyn Connex® Integrated Wall System

WARNING Patient illness may result from improper use of oral and rectal

temperature probes. Using the incorrect probe may also produce inaccurate
measurements.

• Use only oral probes, identified by a blue ejection button at the top of the probe, to
take oral and axillary temperatures.

• Use only rectal probes, identified by a red ejection button at the top of the probe, to
take rectal temperatures.

WARNING Patient illness or cross-contamination may result from improper
placement of oral and rectal temperature probes in the probe wells.

• Place only oral probes, identified by a blue ejection button at the top of the probe, in
the blue probe wells.

• Place only rectal probes, identified by a red ejection button at the top of the probe, in
the red probe wells.

WARNING Inaccurate measurement risk. Never take an axillary temperature
through the patient's clothing. Carefully place the probe in the axilla, avoiding
contact with other objects or material. Always verify direct contact between the
probe cover and skin.

WARNING Patient injury risk. When taking rectal temperatures, insert the probe
tip only 5/8 inch (approximately 1.5 cm) inside the rectum of adults and only 3/8 inch
(approximately 1 cm) inside the rectum of children to avoid the risk of bowel
perforation.

WARNING Never use a damaged temperature probe. The thermometer consists
of high-quality precision parts and should be protected from severe impact or
shock. Do not use the thermometer if you notice any signs of damage to the probe
or monitor. If the thermometer probe is dropped or damaged, remove it from use
and have it inspected by qualified service personnel.

CAUTION Inaccurate measurement risk. Patient activities such as strenuous
exercise, ingesting hot or cold liquids, eating, chewing gum or mints, brushing teeth,
or smoking may affect oral temperature measurements for up to 20 minutes.

CAUTION Inaccurate measurement risk. Always use new probe covers taken
from the monitor's probe cover box holder to ensure accurate temperature
measurements. Probe covers taken from other places or that haven't stabilized in
temperature may result in inaccurate temperature measurements.

Temperature mode selection

The monitor with the temperature module takes a patient temperature in either Predictive (Normal)
or Direct mode. The default setting is the Predictive mode.

WARNING Inaccurate measurement risk. To ensure optimal accuracy, always
confirm that the correct mode and site are selected.

WARNING Patient injury risk. Do not exceed the recommended temperature
measurement durations in Direct mode. Continuous measurement durations of 3
minutes at the oral and rectal sites and 5 minutes at the axillary site are
recommended for accurate measurement. Do not continuously measure beyond 10
minutes in any mode.

Directions for use Patient monitoring 81

Predictive mode

Is a one-time measurement that takes a temperature in approximately 6 to 15 seconds. Removing
the probe from the probe well, loading a probe cover, and holding the probe tip in place at the
measurement site initiates a Predictive mode measurement. The monitor sounds a tone to indicate
the end of a predictive measurement.

Direct mode

Provides continual temperature measurements. For oral and rectal measurements, it is
recommended to measure temperature until the temperature stabilizes or for 3 minutes. For axillary
measurements, it is recommended to measure temperature until the temperature stabilizes or for 5
minutes. The monitor changes to Direct mode approximately 60 seconds after the probe is removed
from the probe well.

CAUTION The monitor does not retain Direct mode temperatures in memory.
Therefore, it is important to note the temperature before removing the thermometer
probe from the measurement site and then manually record it in the patient record.

After 10 minutes of using the Direct mode, the monitor generates a technical alarm condition and

SpO2

SpO2 frame

SpO2 and pulse rate monitoring continuously measures saturation level of oxygen in hemoglobin as
well as the pulse rate in a patient through a pulse oximeter.

The SpO2 frame displays data and controls used in pulse oximetry measurements.

Patient monitoring Welch Allyn Connex® Integrated Wall System

88

The frame provides a numeric view and a waveform view of SpO2 data. You can toggle between
views by touching the left side of the frame.

SpO2 numeric view

The numeric view indicates the SpO2 saturation percentage and the pulse amplitude. Features of
this view differ based on the type of sensor enabled and the profile selected.

Nellcor sensor

Monitor profile Spot Check and Triage profiles

Masimo sensor

Monitor profile Spot Check and Triage profiles

Pulse amplitude

The pulse amplitude bar indicates the pulse beat and shows the relative pulse strength. More bars
illuminate as the detected pulse gets stronger.

Response Mode Control

The Response Mode Control allows you to set the SpO2 measurement time to either Normal or
Fast.

Perfusion index

Perfusion Index (PI) is an SpO2 feature available only with Masimo-equipped monitors.

Directions for use Patient monitoring 89

PI is a relative reading of pulse strength at the monitoring site. PI is a numerical value that
indicates the strength of the IR (infrared) signal returning from the monitoring site. PI display
ranges from .02 percent (very weak pulse strength) to 20 percent (very strong pulse strength). PI is
a relative number and varies between monitoring sites and from patient to patient, as physiological
conditions vary.

During sensor placement, the PI can be used to evaluate the appropriateness of an application
site, looking for the site with the highest PI number. Placing the sensor at the site with the
strongest pulse amplitude (highest PI number) improves performance during motion. Monitor the
trend of the PI for changes in physiological conditions.

SatSeconds™ alarm management

The SatSeconds feature is an SpO2 alarm management system available only with monitors that
are equipped with Nellcor OxiMax Technology.

The SatSeconds feature is the product of the time and magnitude that a patient falls outside of the
SpO2 alarm limits. For example, three points below the alarm limit for 10 seconds equals 30
SatSeconds. An alarm is triggered only when a desaturation event reaches the SatSeconds limit.
The SatSeconds feature is clinician controlled and can be set to 0, 10, 25, 50, or 100 SatSeconds. If
a desaturation event resolves on its own within the preset time, the clock will automatically reset
and the monitor will not alarm.

Note The SatSeconds feature has a built-in safety protocol that sounds an alarm
