II. 1. BLOOD PRESSURE OPERATING MODES
When a blood pressure measurement cycle is initiated, the cuff will automatically inflate
to the default pressure level.
The cuff will immediately begin to deflate in a stepped fashion and will determine systolic
pressure and diastolic pressure from the pulses sensed by the cuff at various pressure levels. This is the oscillometric method of non-invasive blood pressure monitoring.
Blood pressure measurements may be initiated manually, or automatically at time intervals determined by the user.
At the completion of a measurement cycle the systolic and diastolic pressures are displayed. If the Monitor is in Automatic Mode, the measured values are kept on display
until the next BP measurement is initiated. When not in Automatic Mode, the measured
values are displayed for two minutes, after which time the display screen is blanked. The
most recent BP measurement may be recalled by pressing the REVIEW button.
When in Automatic Mode, if the unit is unable to determine the systolic or diastolic
value, the measurement will be automatically repeated once.
II. 1. A. MAX/MIN BLOOD PRESSURE RANGES
The maximum and minimum ranges of blood pressure are detailed below:
Measurement
Maximum Minimum
Systolic Pressure 250 mmHg 60 mmHg
Diastolic Pressure 160 mmHg 30 mmHg
WELCH ALLYN VITAL SIGNS MONITOR OPERATOR MANUAL
8
II. 1. B. BLOOD PRESSURE MANUAL MODE
In the Manual Mode, a single blood pressure determination is made only when the START
button is pushed. The manual mode is the default mode of operation for blood pressure
determinations.
A measurement cycle may be cancelled at any time by pressing the CANCEL button. This
action immediately initiates a rapid cuff deflation.
The blood pressure measurement data will appear on the display immediately following
the measurement. The display will blank after two minutes. If the display is blanked,
pressing the REVIEW button on the front panel will recall the measurement. Up to 99
prior measurements are available for review or printing.
In Blood Pressure Manual Mode, the following alarm limits may be activated; SYSTOLIC
HIGH LIMIT, SYSTOLIC LOW LIMIT, DIASTOLIC HIGH LIMIT, DIASTOLIC LOW
LIMIT, PULSE RATE HIGH LIMIT and PULSE RATE LOW LIMIT. Blood pressure determinations which activate alarms are indicated by flashing displays and a repetitive audible tone. If an alarm limit is violated, subsequent blood presssure determinations may be
made only after the alarm condition is reset by pressing any button on the Monitor's display.
II. 1. C. BLOOD PRESSURE AUTOMATIC MODE
The Automatic Blood Pressure Mode is entered by pressing the AUTO button. Pressing
the AUTO button displays a choice of 11 cycle interval times as follows: "St" (STAT mode),
1 minute, 3 minutes, 4 minutes, 5 minutes, 10 minutes, 15 minutes, 30 minutes, 45 minutes, 60 minutes and 90 minutes. These choices represent the time interval from the
beginning of one cycle to the beginning of the next automatic cycle. STAT mode allows
the monitor to take continuous blood pressure measurements for 15 minutes. In addition,
the operator may choose to disable the Auto Mode by choosing "--" (two dashes).
Note: In the 1-minute automatic cycle mode, the Welch Allyn Vital Signs Monitor will
automatically take blood pressure measurements in 1-minute intervals for up to 15 minutes.
A measurement cycle may be cancelled at any time by pressing the CANCEL button. This
action immediately initiates a rapid cuff deflation.
The blood pressure measurement data will appear on the display immediately following
the measurement and will remain displayed until the next measurement cycle is initiated.
In Blood Pressure Auto Mode, the following alarm limits may be activated; SYSTOLIC
HIGH LIMIT, SYSTOLIC LOW LIMIT, DIASTOLIC HIGH LIMIT, DIASTOLIC LOW
LIMIT, PULSE RATE HIGH LIMIT and PULSE RATE LOW LIMIT. Blood pressure determinations which activate alarms are indicated by flashing displays and a repetitive audible tone. Any alarm limit violation must
be reset to continue automatically timed blood
pressure determinations. The alarm may be reset by pressing any button on the Monitor's
display.

II. 2. TEMPERATURE OPERATING MODES
Thermometry measurements are made with the integrated Welch Allyn SureTemp®thermometer. Oral and rectal probes utilize single-use disposable probe covers which limit
cross-contamination. Oral, axillary or rectal temperatures are taken using 'Normal' or
'Monitor' operating modes. Axillary temperatures are taken using the oral probe.
In Normal mode the thermometer's microprocessor "predicts" body temperature in about
4 seconds for oral temperatures, about 10 seconds for axillary temperatures and in about
15 seconds for rectal temperatures. The Monitor mode displays the patient's actual temperature after 3 minutes for oral/rectal mode and 5 minutes for axillary mode, and will
continue to display an updated temperature as long as the probe remains in place.
Note: Normal mode axillary temperatures (10 seconds) are accurate only for children
under the age of four.
Note: THE WELCH ALLYN VITAL SIGNS MONITOR IS NOT INTENDED TO BE
USED ON NEONATAL PATIENTS.
Temperature readings may be displayed in Fahrenheit or Celsius scales.
II. 2. A. MAX/MIN TEMPERATURE RANGES
Measurement Maximum Minimum
Temperature, °F 108.0°F 84.0°F
Temperature, °C 42.2°C 28.9°C
II. 2. B. TEMPERATURE NORMAL MODE
In Normal mode, the device will measure temperature at discrete intervals and then calculate the rate of change according to a proven algorithm. This allows the thermometer to
predict the end point that the thermistor would reach if it were left in the mouth until it
reached mouth temperature. This predictive feature allows the thermometer to arrive at
an accurate oral temperature reading in approximately 4 seconds.
Normal mode is the default operating mode for temperature determinations.
Operator selectable patient alarm limits are not available in temperature Normal mode.
However, temperatures which are outside of the operating range of the device will be
noted on the temperature display.
WELCH ALLYN VITAL SIGNS MONITOR OPERATOR MANUAL
10
II. 2. C. TEMPERATURE MONITOR MODE
Continuous Monitor mode operation is normally used for longer term monitoring and
when difficult situations prevent accurate temperatures from being taken in the Normal
mode. The probe must be in contact with tissue for at least three (3) minutes for accurate
oral/rectal temperature measurement and five (5) minutes for accurate axillary temperature measurement. Monitor mode temperatures may not be identical to predicted 'Normal'
temperatures because of ambient temperature influence and other factors. The trend in
temperature is the important standard to be observed when in the Monitor mode.
Operator selectable patient alarm limits are not available in temperature Monitor mode.
However, temperatures which are outside of the normal operating range of the device will
be noted on the temperature display.
II. 3. SpO2OPERATING MODE
The Welch Allyn Vital Signs Monitor incorporates either the Nonin® or Nellcor Puritan
Bennett
TM
pulse oximetry module which determines arterial oxyhemoglobin saturation
(SpO2%) by measuring the absorption of red and infrared light passed through the tissues.
Changes in absorption caused by pulsation of blood in the vascular bed are used to determine arterial saturation and pulse rate.
Oxygen saturation percent is calculated with each pulse detected, and thus the monitor
display is continually updated. The pulse signal bar graph is an indicator of the strength
and quality of the detected pulses.
When SpO2is measured, the patient's pulse rate is also measured and displayed. A pulse
rate measurement from the SpO2determination overrides a pulse rate measurement
derived from a blood pressure measurement.
When measuring SpO2the user may enable the SpO2Pulse Tone feature. A short audible
tone is emitted with every patient heartbeat. The frequency of the tone is based on the
patient’s SpO2level. The lower the frequency of the tone, the lower the patients SpO2level.
In SpO2monitoring mode, operator selectable alarm limits for low SpO2% may be activated. A condition which violates the SpO2low limit alarm is indicated by a flashing display and repetitive audible tone. Should a patient alarm condition for SpO2or pulse rate
occur, the Monitor will indicate an alarm condition (flashing & beeping) while continuing
to monitor and display the patient's current SpO2%. The alarm will automatically reset
when the patient's condition returns to within the preset alarm parameters.
Should a patient alarm condition for SpO2or pulse rate occur, the operator may invoke
"Silence Mode" by pressing the SILENCE button. This will silence the audible tone (display will continue to flash), while the practitioner attends to the patient and the monitor.
Silence mode resets automatically after 30 seconds, or when the patient's condition returns
to within the preset alarm parameters.
WELCH ALLYN VITAL SIGNS MONITOR OPERATOR MANUAL
11
Removal of the SpO2sensor from the patient will initiate an alarm, unless the SpO2and
pulse rate alarms are turned off. To reset the sensor alarm, press any button on the
Monitor's display.
SpO2is generally measured via pulses detected using a finger sensor. However, for certain situations SpO2may be measured at alternate sites including the earlobe, forehead
and toes. Special sensors must be employed in these situations.
II. 3. A. MAX/MIN SpO2RANGES
The SpO2sensor is designed to detect oxygen saturation as follows.
Maximum
Minimum
SpO
2
99% 40%
II. 3. B. SpO2MONITOR MODE
The SpO2monitor performs most accurately with the fingerclip sensor, which may be
used on all fingers except the thumb. The finger clip sensor is recommended for spot
checks or short term continuous monitoring.
The device determines arterial oxyhemoglobin saturation (SpO2%) by measuring the
absorption of red and infrared light passed through the tissue. Oxygen saturation and
pulse rate are displayed on the LED digital display. On each detected pulse, the pulse signal bar graph flashes. The intensity of this signal is a simple visual indicator of waveform
signal strength, and can identify situations where the pulsatile nature of the tissue may
not be adequate for an accurate SpO2reading. The update interval of the bar graph
should correspond to the patient's pulse rate. This is an indication of the quality of the
SpO2signal.
All Welch Allyn Vital Signs Monitors with pulse oximetry capability are equipped with a
pulse tone. This audible tone beeps in synchronization with each beat of the patient’s
heart. In addition, the frequency of the tone will vary based on the patient’s oxygen saturation value. The higher the tone’s frequency, the higher the patient’s oxygen saturation
value. The user may change the pulse tone volume, or turn this feature off as necessary.
WELCH ALLYN VITAL SIGNS MONITOR OPERATOR MANUAL
12
II. 4. PULSE RATE FEATURE
The Welch Allyn Vital Signs Monitor is capable of determining pulse rate as an adjunct to
the blood pressure measurement and the SpO2measurement.
The pulse rate, in beats per minute, will be determined primarily from the SpO2measurement methodology. In the case where SpO2is not available, or is disabled, the pulse rate
display will be driven by data from the blood pressure measurement method.
There are two operator selectable alarm limits for the pulse rate. They are PULSE RATE
HIGH LIMIT and PULSE RATE LOW LIMIT. Pulse rates which activate alarm limits are
indicated by a flashing display and a repetitive audible tone.
Should a pulse rate alarm occur when the pulse rate measurement is derived from the
blood pressure measurement, no subsequent blood pressure or pulse rate measurements
may be made until the alarm is reset. The alarm may be reset by pressing any button on
the Monitor's display.
Should a pulse rate alarm occur when the pulse rate measurement is derived from the
SpO2measurement, the monitor will indicate an alarm condition (flashing & beeping)
while continuing to monitor and display the patient's current SpO2% and pulse rate. The
alarm will automatically reset when the patient's condition returns to within the preset
alarm parameters.
Should a patient alarm condition for pulse rate occur during SpO2monitoring, the operator may invoke "Silence Mode" by pressing the SILENCE button. This will silence the
audible tone (display will continue to flash), while the practitioner attends to the patient
and Monitor. Silence mode resets automatically after 30 seconds, or when the patient's
condition returns to within the preset alarm parameters. If an alarm limit is violated, subsequent determinations of any type may only be made after the alarm condition is reset.
