Setup

This chapter describes the set-up procedures for patient monitoring.

Connections

Use the procedures described below to connect components to the monitor.

Connecting AC Power

The monitor operates on DC power, supplied by either the internal battery or the AC power adapter. (For information on the battery, refer to “Battery Operation” on page 71 and “Electrical” on page 76.)

When the AC power adapter is connected, it simultaneously powers the monitor and charges the internal battery. When the AC power adapter is not connected, the monitor operates on the internal battery.

Caution Use only the medical-grade AC power adapter approved by Welch Allyn. (Refer to the Welch Allyn Parts and Accessories Guide (810-0409-XX) for ordering information.) Using an unqualified power adapter can have the following results:

• violation of isolation requirements

• hazard to the patient

• damage to the monitor

• nullification of the product warranty

Page 18

12 Chapter 2 Setup Welch Allyn Vital Signs Monitor 300 Series

To use the AC power adapter:

1. Plug the power adapter into the AC power source.

2. Plug the power adapter connector into the monitor DC port.

AC Power Adapter Port

Use the AC power adapter to fully charge the battery before using the monitor. (This can take up to 12 hours.)

Monitoring Blood Pressure

WARNING To ensure safe and accurate NIBP measurements, use only cuffs and hoses approved by or supplied by Welch Allyn.

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.

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

WARNING When patients are being monitored frequently or monitored for a prolonged period, regularly remove the cuff to inspect it and to inspect the patient’s cuffed extremity for ischemia, purpura, or neuropathy.

WARNING To avoid the risk of intravenous line misconnection and possible introduction of air into a patient’s blood, do not fit the NIBP system with Luer Lock adapters.

WARNING Do not place the cuff on an extremity already being used for intravenous infusions or SpO

monitoring.

WARNING Do not place the cuff where it can affect proper circulation.

WARNING NIBP measurements may be inaccurate in the presence of excessive

motion artifact.

Caution 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.

Page 38

NIBP Preparation

Before you start any NIBP measurement, always follow the steps described in these procedures:

• “Changing the Target Pressure” on page 32

• “Selecting a Cuff” on page 32

• “Positioning the Cuff” on page 33

Changing the Target Pressure

Follow these steps to change the target pressure (default initial pressure for cuff inflation) for the current patient type:

1. Press until the message window displays TARGET PRESSURE.

The SYS window displays the current setting for initial inflation pressure.

2. Press or to raise or lower the preset pressure value to the target level.

To set the displayed pressure level and return to normal operation, either do nothing for 10 seconds or press any button other than or . If you press a function button (such as ), the monitor returns to normal operation with that function ( ) activated.

Note

Selecting a Cuff

You can tell whether the cuff size is appropriate by putting the cuff on the patient and then inspecting the fit. If the edge marking lies somewhere between the two range markings, then the fit is correct.

You can also find the correct cuff by measuring the circumference of the patient’s arm at the biceps:

Target pressure is a nominal starting point. If it is too low to take a measurement, the monitor takes another measurement using a higher initial pressure.

Positioning the Cuff

For the most accurate measurement, do the following:

1. Position the cuff on the bare arm, midway between the shoulder and the elbow.

Typical cuff positions are shown in this illustration:

Neonatal

Adult and Pediatric

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

Note

Be sure that the cuff is neither too tight nor too loose. When putting it on the patient, wrap it so that you can comfortably fit two fingers between the cuff and the arm.

Be sure that the air hose has no kinks or twists.

During an NIBP measurement, limit the movement of the cuff and the cuffed extremity.

If the cuff is not level with the heart, add 1.8 mmHg to the displayed reading for each inch of elevation above the heart, or subtract 1.8 mmHg from the displayed reading for each inch of elevation below the heart.

Always use the appropriate cuff size for each patient.

How Changing the Patient Type Affects MAP Defaults

When you cycle power to the monitor, the monitor stores all current settings before shutting down. It then uses these saved settings when it powers up again. (This does not affect the factory default settings.)

Whenever you enable or disable MAP for a given patient type—Adult, Pediatric, Neonatal—the current enabled/disabled setting becomes the default power-up setting for that patient type.

For example: If the monitor is set to Neonatal and you set MAP Disabled, MAP Disabled becomes the default setting for neonatal patients until you change the enabled/disabled setting again.

Enabling and Disabling MAP Measurement

See “MAP Measurement Enable and Disable” on page 25.

STAT Measurement

If the selected interval is STAT, the monitor takes repeated NIBP measurements for 5 minutes, starting a new cycle each time the cuff deflates below safe venous return pressure (SVRP) for two seconds.

Current cuff pressures are not dynamically displayed during a STAT reading. The message window displays the NIBP reading from the previous cycle until the current cycle finishes. (Before the first cycle finishes, the display reads ‘0.’)

Monitoring Pulse Rate

The monitor displays the pulse rate at the end of all NIBP or SpO2 measurements. It displays NIBP pulse information only if no SpO

If the SpO amplitude indicator rises and falls in rhythm with the monitored heart rate. The higher the display rises, the stronger the measured pulse; however, the height of the indicator display is not mathematically proportional to the volume of the pulse.

Setting the Temperature Measurement Type

The monitor, if configured with the temperature option, can provide both predictive and monitored temperature measurements.

A predictive measurement is a one-time measurement that takes only a few seconds. It results in a single temperature reading which is displayed at the end of the brief measurement period. The monitor sounds three short tones to indicate the end of a predictive measurement.

A monitored measurement is a continuous temperature monitoring, used when the situation prevents accurate predictive measurement. For oral and rectal measurements, three minutes of monitoring is recommended. For axillary measurements, five minutes of monitoring is recommended.

WARNING Do not exceed the recommended measurement periods of three minutes for oral and rectal measurements and five minutes for axillary measurements.

During a monitored measurement, the temperature is displayed dynamically throughout the measurement period. Unlike a predictive measurement, the monitor does not indicate the end of any elapsed time for a monitored measurement.

To select the temperature measurement type:

1. Press repeatedly until TEMP MODE appears in the display window.

2. Press or to cycle to the option you wish to select:

Page 63

Directions for Use Chapter 4 Alarms and Alerts 57

Note

For patient safety, all alarms are reset to the factory default levels whenever the patient type is changed. This means that you must either accept the default alarm limits or set new limits every time you change patient type ( , , or ).

The ‘high’ alarm for any vital sign is always higher than the ‘low’ alarm for the same vital sign. For example, the alarm limit for systolic high is always higher than the alarm limit for systolic low.

A reading that exactly reaches the alarm threshold without crossing the alarm threshold does not qualify as an alarm condition.

Set alarms for systolic and diastolic blood pressure, pulse rate, and SpO2 as follows:

1. P r e s s .

• All display windows are blanked, other than the message window and the SYS window.

• The message window displays HIGH ALARM.

• The SYS window displays the current alarm setting for the upper limit of systolic blood pressure. This setting is a numeric blood pressure level or it is ‘- -’, indicating that no alarm is set for the selected vital sign.

2. For the selected vital sign, do one of the following:

• Leave the limit unchanged or

• Press or as needed to change the limit to another value or to ‘- -’ to disable the alarm.

3. Press to accept the displayed alarm limit and advance to the next vital sign.

The display moves to the next window (for example, from SYS HIGH to SYS LOW, or from SYS LOW to DIA HIGH).

4. To continue changing alarm limits, repeat from step 2; to return to normal operation, do nothing for 10 seconds.

To set the MAP alarm limits, if MAP is enabled:

5. Continue from (step 3) until you have cycled through all of the display windows; that is, until you have cycled through SpO2 LOW.

The display moves to the message window, which displays the current MAP high alarm limit, as follows:

MAP ↑ XXX mmHg or MAP ↑ XXX kPa

MAP ↓ XXX mmHg or MAP ↓ XXX kPa

Nurse Call

The monitor can be connected to a Nurse Call system through a customized cable that connects to the Nurse Call connector. When the cable is connected and operational, the monitor immediately notifies the Nurse Call system when a patient alarm occurs.

Nurse Call Cable

Connector

To connect the monitor to a Nurse Call system, you must have a cable (Welch Allyn part number 008-0634-XX or equivalent) that has been adapted to your Nurse Call system. This cable can be built or customized by a biomedical engineering department or other appropriate technical resource, using the specification described on “Nurse Call” on page 81.

WARNING Although the Nurse Call option enables remote notification of an alarm condition, it is not intended to replace appropriate bedside patient surveillance by trained clinicians.

Note

When a patient alarm occurs, pressing silences the monitor alarm tone and the Nurse Call alarm for 90 seconds, but does not suspend the visual alarm indicator on the monitor.

Battery Operation

Battery Low Warning

When the battery charge is low, a warning tone sounds and the Low Battery indicator flashes continuously. From the time comes on, the battery has enough charge remaining to perform at least one of the following over the next hour:

• 20 NIBP cycles

• 30 minutes of SpO

• 20 predictive temperature determinations

• a single printing of 99 stored data sets

To avoid a shutdown of the monitor due to battery failure, plug in and connect the AC power adapter.

Battery Failure

If the monitor continues to run on battery power after comes on, the battery eventually fails. Battery failure is indicated by the following:

monitoring

• flashes continuously.

• A short tone repeats continuously. Pressing does not suppress this tone.

• The message LOW BATTERY is displayed in the message window.

• An error code is displayed in the systolic window (SYS) for 10 seconds, and then

all monitor displays are blanked.

• An error signal—2 short tones—sounds once.

Page 78

72 Chapter 7 Reference Welch Allyn Vital Signs Monitor 300 Series

Battery failure causes the immediate suspension of all monitoring and print functions. If the wall charger is not plugged in, then the monitor shuts off 15 minutes after the battery discharge reaches failure level. If automatic NIBP is selected, and if the wall charger is plugged in before the monitor shuts down, then automatic measurement cycles resume as soon as the battery voltage rises above the failure threshold.

Battery Replacement

When the battery has reached end of life, replace it with an identical battery from Welch Allyn (reorder number 501-0015-XX).

Caution Always recycle batteries according to local regulations. Never dispose of batteries in waste receptacles.

Electrical

Power Requirements

The medical-rated isolation AC power adapter connected to the AC supply must supply 8 volts DC and 0.74 amperes.

Battery

The monitor uses a (supplied) sealed lead-acid, 6V, 4 Ah battery with external recharge capability.

The battery charges to at least 90% capacity in 12 hours. The AC power adapter, when connected, simultaneously operates the monitor and charges the battery; it charges the battery more rapidly if it is not simultaneously operating the monitor.

Using a new, fully charged battery, the monitor can be operated continuously for at least 8 hours of Adult NIBP monitoring, at 3-minute intervals, with simultaneous and continuous monitoring of temperature and SpO

In other words, a new, fully charged battery supports at least 165 Adult NIBP readings at 3-minute intervals while simultaneously and continuously monitoring and displaying temperature and SpO

values.

Leakage Current

For maximum patient electrical isolation, connect a computer to the monitor only when the monitor is not connected to a patient or when the computer is outside the patient field running on battery power.
