6 Vital Signs Monitor
Special Features
The following special features enhance the use of the Welch Allyn Vital Signs Monitor:
• Choice of Measurement Modalities
• Non-invasive blood pressure, temperature, and SpO2 measurements may be made
independently or simultaneously.
• Operator Selectable BP Measurement Intervals
• Automatically takes BP measurements at intervals from 1 to 90 minutes. Special "STAT"
mode allows continuous blood pressure measurements for up to 15 minutes.
• Programmable Alarms
• Both visual and audible alarms indicate readings outside of operator programmable high/low
limits, and also indicate system hardware/software problems.
• Non-Invasive, Oscillometric BP
• Eliminates the risks associated with invasive monitoring, with no need for microphones or
external transducers.
• Prior Data Recall
• Measurement data from up to 99 previous determinations is available at the touch of a
button.
• Operator-Friendly Results
• Large, easy-to-read LED displays are complemented by an integrated thermal printer.
• AC or Self-Contained Battery Power
• The Welch Allyn Vital Signs Monitor is conveniently available in many locations, for a variety
of monitoring needs, including interdepartmental transport within the facility.
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 deter-
mined 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 measure-
ment is initiated. When not in Automatic Mode, the measured values are displayed for two min-
utes, 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 mea-
surement will be automatically repeated once.
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.
