Overview 1-1

Intended Use

Large, colored LEDs display the current parameters. To increase readability, each parameter has its own unique color. A large LCD screen displays historical information and is also used to configure the system.

The monitor uses dynamic linear deflation blood pressure technology and features a full array of alarm settings for each displayed parameter. It can hold up to 400 lines of data that can be viewed or printed in several formats.

The monitor can operate on AC power or on a 6-volt internal battery.

Intended Use

The VS1 monitor is intended to monitor a single patient’s vital signs in a hospital, outpatient surgery, practitioner facilities, or in an environment where patient care is provided by qualified healthcare personnel who will determine when use of the device is indicated, based upon their professional assessment of the patient’s medical condition. The patient populations are adult, pediatric, and neonatal.

The device is capable of monitoring pulse rate, non-invasive blood pressure, temperature, and SpO2. The device is intended for use by qualified healthcare personnel trained in its use.

7Connect the bar code scanner interface cable to the back of the VS1 monitor on the

I/O connector. Secure the cable in place by tightening the top and bottom retaining screws

in the connector.

Attach the scanner’s mounting arm to the roll stand just below the unit so that the scanner is held to one side of the unit. Tighten the arm’s mount by tightening the two allen bolts with the appropriate wrench.

Attach the enclosed “Scanner Reset” label to the scanner’s mounting arm for easy access when needed. This label is used to reset the scanner when it appears the scanner is no longer reading the patient’s bar code correctly.

8 Press the Power ON/OFF button on the lower left corner of the front panel of the monitor.

Powering Up and Down

After you press the Power On/Off button, the Power On LED turns green, and the unit then initializes and performs a self-test. During this process, 888 appears in all of the LED displays. As each parameter is initialized, the displays change from 888 to --- and the Line List display (the Main screen) appears on the LCD screen. After this verification is complete for all parameters (about 10 seconds), the monitor is ready for use.

To turn the monitor off, press and hold the button for at least three seconds. A beep tone will sound at onesecond intervals until the unit turns off (in approximately 3 seconds).

Sleep Mode

If the monitor is on, but it is not used for five minutes, it enters Sleep mode. Sleep mode can also be entered by briefly pressing the Power On/Off button. In Sleep mode, all parameters are suspended, which decreases power discharge when the monitor is running on battery and decreases battery charging when the monitor is plugged in to an AC power supply.

Push any button to power up the unit. The initialization process begins and the parameters will become active in approximately 10 seconds.

Sleep mode is the default setting. If the monitor will normally be on AC power, it can be set to bypass S leep mode. Contact your biomed to change this setting.

Recharging the Battery

The VS1 is shipped with a fully charged battery. The battery recharges automatically any time the power cord is plugged into an AC power source. Recharging from a fully drained battery to a fully charged battery can take up to four hours.

Setting Up the Monitor 2-3

Disposing of the Monitor

The Battery Charging Indicator LED on the front of the monitor shows the charging status when the unit is plugged in.

Color	Status
Red	The battery is charging.
Green	The battery is fully charged and ready to use.

When the monitor is on, but is not plugged in, the Battery Indicator icon, which is located in the lower right portion of the Line List display, also indicates current battery power levels.

Note—Always verify that the Battery Charging Indicator LED is lit when the unit is connected to an AC outlet. A monitor that is plugged in, but shows no Battery Charging light indicates a problem with the charging of the monitor. See the Troubleshooting section for information.

A fully charged battery (more than 90% of capacity) will normally last more than six hours at 15-minute spot-check measurement frequencies. If the monitor is stationary, it should be connected to an AC power supply to help ensure maximum battery power availability.

Note—If the monitor will not be used for an extended period of time, remove the battery.

For information on removing or replacing the battery, see the Service manual.

Note—If, after fully charging the battery, you unplug the monitor, and then plug it back in, the Battery Charging LED will turn red. To determine the current battery power level, see the Battery Indicator icon in the lower right corner of the main screen. This icon appears when the unit is unplugged.

Disposing of the Monitor

To avoid contaminating or infecting personnel, the environment or other equipment, make sure you disinfect and decontaminate the monitor appropriately before disposing of it in accordance with your country’s law for equipment containing electrical and electronic parts.

For disposal of parts and accessories, such as SpO2, where not otherwise specified, follow local regulations regarding disposal of hospital waste.

For disposal of the lead-acid battery, follow local regulations for safe disposal of lead.

2-4 Setting Up the Monitor

3 Operating Your Monitor

This chapter describes some of the basic functionality of the VS1 monitor. It includes information on using the controls to change system settings, save data, and change the system date and time.

Note—This manual describes the fully configured VS1 monitor (model PM2240P) which includes NIBP, Pulse, Pulse Oximetry, and Temperature displays, plus a recorder. If you do not have a fully configured monitor, some of the information in this manual may not apply to your unit.

Using the Monitor Safely

Ensure that the monitor is in proper working condition before clinical use. If the accuracy of any measurement does not seem reasonable, first check the patient’s vital signs by alternative means and then with the monitor to make sure it is working properly.

If you connect the monitor to any instrument, verify proper operation before clinical use. Refer to that instrument’s Instructions for Use guide for full instructions.

Anyone who connects additional equipment to the signal input port or signal output port configures a medical system and is therefore responsible to ensure that the system complies with the requirements of system standard IEC Standard 60601-1. If in doubt, contact the Philips Response Center or your local Philips representative.

The care and handling of all accessories should be in accordance with local hospital guidelines, policies, and procedures.

Note—The monitor and its accessories must be tested by qualified service personnel at regular intervals to verify proper operation, according to the procedures of the user’s institution.

Warning Explosion hazard. Equipment not suitable for use in the presence of a flammable anesthetic mixture with air, or with oxygen or nitrous oxide.

Electric shock hazard. Covers should be removed only by qualified service personnel. There are no user-serviceable parts inside.

If you suspect a problem with parts inside the monitor, unplug the device and contact your biomed or local Philips representative. Do not open the monitor or attempt to change the battery.

Do not connect accessory equipment to the monitor’s data interface.

Route patient cabling to reduce the possibility of patient entanglement or strangulation.

Do not place the monitor in any position that might cause it to fall on the patient. Do not lift the monitor by the power supply cord or patient connections because disconnection could then result in the monitor dropping on the patient.

Service should be performed by qualified service personnel only.

This device can be damaged by energy discharged from a defibrillator. Disconnect the SpO2 and temperature probes from the monitor before defibrillator discharge.

All wire-lead patient-connected transducer assemblies are subject to reading error, local heating, and possible damage from high-intensity sources of RF energy. Electro-surgical equipment’s capacitivelycoupled currents may seek alternate paths to ground through probe cables and associated instruments; patient burns may result. If possible, remove the probes from patient before activating the surgical unit or other RF source. To reduce hazards, select a temperature monitoring point that is remote from the expected RF current path to ground return pad. Appropriate probe selection and application must be determined then applied.

Operating Your Monitor 3-1

LCD Screen Displays

To ensure patient electrical isolation, connect only to other equipment that provides patient electrical isolation.

Do not use extension cords to connect the monitor to electrical outlets.

Do not use the monitor during MRI (magnetic resonance imaging) scanning. Induced current could potentially cause burns. The monitor may affect the MRI image, and the MRI unit may affect the accuracy of the monitor’s measurements.

Sterilization is not recommended for this monitor, related products, accessories or supplies unless otherwise indicated in the Instructions for Use for the accessories and supplies.

Electromagnetic interference may cause disruption of performance. Protect the monitor from sources of intense electromagnetic radiation. This device is designed to provide resistance to electromagnetic interference. However, because of the proliferation of radio-frequency transmitting equipment and other sources of electrical noise (such as cellular phones and mobile two-way radios), high levels of such interference due to close proximity or strength of a source may result in disruption of performance of this device. Disruption may be evidenced by erratic readings, cessation of operation or other incorrect functioning. If this occurs, survey the site to determine the source of the disruption, and actions taken to eliminate the source. If you need assistance, contact the Philips Response Center.

LCD Screen Displays

The screens in the VS1 monitor are parameter-dependent, meaning that you will only see screens that apply to the parameters in your own monitor. This section describes how to move between screens and how to change values within screens using the buttons and soft keys on the LCD.

Note—If you are viewing historical information when the monitor saves a listing to memory, the view will not display the newly saved listing. If historical information is left on the screen for more than 30 seconds, and no buttons are pressed, the screen will revert to the latest information.

Soft Keys

The soft keys are used to select settings that you want to review or change. Pressing one of these soft keys yields more information about the setting that appears in the box above the selected key, and the screen will change accordingly.

After using the soft keys to display a secondary screen, you can use the OK button to move the cursor through the settings on the screen. Use the Up and Down buttons to increase or decrease values that are highlighted or to toggle between two settings.

Saving Data

The monitor automatically saves information in the Line List memory when:

•A blood pressure measurement is complete.

•An alarm limit is violated.

•A temperature measurement is complete.

•A user-specified interval for storing data has occurred. See the next section, Changing the Save Rate.

•The first SpO2 measurement is received.

If parameters are being measured concurrently, they will be saved to the Line List at the end of the longest running measurement.

The Line List memory can save up to 400 lines of data. If the memory contains 400 lines and an additional measurement is taken, the memory removes the oldest listing and adds the current one.

Data is saved automatically when the unit is turned off. When you turn the monitor back on, the entire Line Listing will again be available.

Changing the Save Rate

The VS1 monitor automatically saves data, as described in the previous section. You can also choose to save data at a rate not related to the cycles described above. To change the rate at which data is saved, open the System Settings screen and change the value of the Line List Input setting.

4 Entering Patient ID Information

This chapter describes how to enter patient IDs in the VS1 monitor.

You do not have to enter an ID to start a measurement; however, if a measurement is started without a patient ID, the monitor identifies the patient as "Unknown." Also, when you enter an ID, either manually or using the bar code scanner, the next set of measurements are assigned to the last ID entered. You cannot enter IDs for later use.

To ensure that all measurements are recorded under the same ID during spot check measurements, you must follow this sequence of steps:

1.Place the SpO2 probe on the patient’s finger.

2.Apply the NIBP cuff and initiate a measurement cycle.

The Temperature measurement can be taken any time during the cuff measurement cycle. As soon as all measurements are complete, all the data is written to the patient’s record

Caution	If cuff intervals or Temperature Monitoring mode are in use, or if the SpO2 sensor is connected to
	the same patient for longer than 5 minutes, the monitor assumes that all measurements taken during
	that time belong to the same patient and places those values in memory under that patient ID.
	If no cuff intervals are set and the SpO2 sensor is not kept on the patient (or if no ID information has
	been entered), as additional measurements are taken, the monitor assumes the vital signs are for a
	new patient and the values are saved to an "Unknown" patient ID.

Using the Bar Code Scanner to Enter Patient IDs

The optional bar code scanner provides a quick way to enter patient ID information in the VS1 monitor.

Step	Action
1	If you have not already done so, connect the scanner to the monitor, as described in Setting Up the
	Monitor on page 2-1. Turn the monitor on.
2	Pull the scanner’s trigger and, with the scanner approximately 6 inches from the patient’s wrist, aim the
	red scanning light at the patient’s bar code.
	As the unit beeps, the ID code is recorded into memory.
3	Verify that the ID displayed on the LCD screen matches the ID on the patient’s wrist, then press the Save
	→ Main soft key.
4	Begin measuring the patient’s vital signs. The measurements are then assigned to the ID you just scanned
	into memory.
	Note—You must begin measurements within 30 seconds of entering the patient ID to ensure that the
	measurements are assigned to the ID you entered.

Monitoring Blood Pressure 5-1

NIBP Safety Information

NIBP Safety Information

Warning The monitor cannot operate effectively on patients who are experiencing convulsions or tremors.

If the NIBP measurement is unsuccessful or when there are doubts about measurement values, assess the patient’s condition immediately. The patient’s condition may have deteriorated to the point where measurement limits are exceeded. If values appear questionable, it is the clinician’s responsibility to repeat the measurements.

Inaccurate measurements can be caused by:

•Incorrect cuff applications or use, such as placing the cuff too loosely on the patient, using the incorrect cuff size, not placing the cuff at the same level as the heart, or placing the cuff over thick clothing or a rolled up sleeve

•A leak in the cuff or tubing

•Excessive patient motion, including CPR and bed movement

•Serious episodes of shock, hypotension, or decreased body temperature

•Frequent episodes of arrhythmia

The monitor displays results of the last blood pressure measurement until another measurement is completed. If a patient’s condition changes during the time interval between measurements, the monitor does not detect the change or indicate an alarm condition.

Sometimes, 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.

A patient’s vital signs can vary dramatically during administration of agents affecting the cardiovascular system, such as those used to raise or lower blood pressure or raise or lower heart rate.

Ensure that heavy objects are not placed on the tubing. Avoid crimping or excessive bending, twisting, or entangling the tubes.

Connecting the NIBP Cuff and Hose

Warning—Use only recommended Philips blood pressure tubing and cuffs. Using other cuffs or tubing can result in inaccuracies.

Connect the appropriate hose to the cuff hose connector on the back of the unit. See Chapter2, Setting Up the Monitor

Select the appropriate sized NIBP cuff and attach it to the hose. Sizes range from neonatal through large adult and thigh.

Smart Inflation Feature

The VS1 monitor provides a Smart Inflation feature that inflates the cuff to a level based on a patient’s individual requirements. The monitor automatically inflates the cuff to a pressure above arterial occlusion. Most monitors inflate to 180 mmHg (23.9 kPa) and then deflate. For some patients, that level of inflation can be uncomfortable. The Smart Inflation feature monitors blood pressure during inflation, and stops inflating when necessary, not at a preset pressure.

5-2 Monitoring Blood Pressure

Specifying Cuff Settings

If for some reason the monitor does not detect arterial occlusion, it will inflate to the value specified in the Initial Inflation Pressure setting, which is described below.

Note—If a patient is moving, shaking, or agitated during a blood pressure measurement, the Smart Inflation feature might interpret the movement as a pulse. If this occurs, the cuff could potentially inflate to a pressure higher than 180 mmHg (23.9 kPa). If your patient cannot remain still, Philips recommends that you disable the Smart Inflation feature. To disable Smart Inflation, press the System soft key, and then press the Cuff Option soft key. Use the OK button to move the cursor to the Smart Inflation choice and uncheck the X. When Smart Inflation is disabled, the monitor will not inflate any higher than the value specified in the Initial Inflation Pressure setting.

Specifying Cuff Settings

Use the Cuff Settings screen to specify the overall parameters of the NIBP cuff measurements. The cuff pressure is shown in the mean arterial pressure (MAP) window during the measurement cycle.

Monitoring Blood Pressure 5-3

Placing the Cuff

Specifying an Initial Inflation Value

Select an Initial Inflation Pressure between 120 mmHg and 240 mmHg for Adult/Pediatric patients and between 80 mmHg and 140 mmHg for Neonatal patients. Inflation values are defined in increments of 20. Settings are saved when the monitor is turned off and become the default when the monitor is powered up.

Enabling the BP Alarm Option

When the BP Upon Alarm option is activated, the monitor will automatically take a second blood pressure measurement if an alarm limit violation occurs. Use the Up and Down buttons to change the setting.

Enabling Smart Clock for Interval NIBP Readings

The Smart Clock setting allows you to specify that the interval NIBP readings occur at a more logical point in time. For example, if a 15-minute interval has been set, and the initial measurement is taken at 11:56, the next "normal" interval would be 12:11. The Smart Clock feature initiates the second measurement at 12:00, then 12:15, then 12:30, and so on. Use the Up and Down buttons to change the setting.

For information on changing the NIBP intervals, see Continuous NIBP Monitoring on page 5-5.

Placing the Cuff

Warning Inspect the application site regularly to ensure skin quality and inspect the extremity of the cuffed limb for normal color, warmth and sensitivity. If the skin quality changes, or if the extremity circulation is being affected, move the cuff to another site or stop the blood pressure measurements immediately. Check more frequently when making automatic or STAT measurements.

Do not place the cuff on an extremity being used for intravenous infusion or any area where circulation is compromised or has the potential to be compromised.

Do not apply the blood pressure cuff to the same extremity as the one to which an SpO2 sensor is attached because the cuff inflation disrupts SpO2 monitoring and leads to nuisance alarms.

Do not apply the cuff to the same arm where IV or blood transfusions are connected.

Measure the patient’s limb and select the proper cuff size. As a general rule, cuff width should span approximately two-thirds of the distance between the patient’s elbow and shoulder.

A listing of all NIBP cuffs is in Chapter 12, “Accessory List.” Follow the NIBP Cuff’s Directions for Use when applying the cuff to the arm and thigh.

For neonatal NIBP measurements, make sure the Neonatal measurement mode	is selected in the Cuff
Setting screen.

Warning—Inaccurate measurements can occur if the neonate’s systolic blood pressure is over 130 mmHg (17.3 kPa), due to the 150 – 155 mmHg (19.9 – 20.6 kPa) maximum inflation pressure of the monitor in Neonatal mode.

Initiating a Single NIBP Measurement

Initiating a Single NIBP Measurement

To take a single NIBP reading:

Step	Action
1	Enter a new patient ID or select a previously saved patient ID. If you choose not to enter an ID, the
	measurements will be assigned to an "Unknown" patient ID.
2	Verify that the correct NIBP mode is selected: Adult/Pediatric or Neonatal.
3	Choose the appropriate cuff and place it on the patient.
4	Press the Cuff Start/Stop button. When the measurement is complete, the Systolic, Diastolic, and Mean
	Arterial Pressure values appear in their corresponding LEDs.

Continuous NIBP Monitoring

The VS1 monitor can be used to continually measure a patient’s blood pressure at specified intervals. You can also create a cuff interval program that measures blood pressure at predetermined times and in predefined intervals.

Note—In Adult mode, the VS1 monitor will sound an alarm at a systolic pressure below 70 mmHg (9.3 kPa), even if a lower limit is set. Neither the feature nor the alarm can be overridden. The range remains adjustable for use in the Neonatal mode, where lower limits can be set.

Selecting a Cuff Interval

The Cuff Interval option initiates a blood pressure reading every n minutes. From the Cuff Interval screen, you can select any of the following intervals: OFF, STAT, 1, 2, 2.5, 3, 5, 10, 15, 20, 30, 60, 90, 120, or180 minutes.

Note—If you select an interval of 1 minute, after 12 measurements, the monitor automatically changes the interval measurement to 5 minutes.

To change the cuff interval value:

Step	Action
1	From the Line List display, press the Cuff soft key. The Cuff Interval screen appears. The currently
	selected cuff interval is displayed.

Monitoring Blood Pressure 5-5

Continuous NIBP Monitoring

Step	Action
2	Press the Up or Down buttons to change the current interval.
3	Press the Save → Main soft key to save the interval you selected and return to the Line List display. The
	interval measurement begins.

You can activate continuous blood pressure measurements from the Cuff Interval screen by pressing the STAT soft key. Measurements are taken for five minutes. After five minutes, the monitor automatically reverts to five-minute intervals.

Note—When STAT is specified, a rapid estimation of systolic blood pressure is displayed upon second and subsequent blood pressure measurements. One beep sounds and a quick estimated systolic value appears. When the measurement is complete, two beeps sound and the actual blood pressure values are displayed.

To stop a cuff interval that is in progress, press the Cuff Start/Stop button. When the continuous measurements are interrupted in this manner, the word "STAT" appears in reverse video on the LCD screen and the measurements cease.

Warning—Do not use STAT mode when using a thigh cuff to monitor NIBP. Use of this mode causes a loss-of-monitoring alarm and shuts down all monitor functionality.

Selecting a Cuff Interval Program

You can create up to five different cuff interval programs that measure blood pressure at predetermined times and in predefined intervals. Four of the timed interval programs (A, B, C, and D) can be configured to your own unit-specific protocols. Program E is pre-configured to a commonly used protocol for training purposes, but it can be modified by following the steps listed below.

Note—Resetting factory defaults (in the Service Screen mode) erases all user-designed cuff programs and resets program E to the factory default values.

To display or edit one of the timed interval programs:

Step	Action
1	From the Line List display, press the Cuff soft key. The Cuff Interval screen appears. The currently
	selected cuff interval is displayed.
2	Press the Down button past the 1 minute interval until you see the program — A, B, C, D, or E — that
	you want to review or modify.
3	Press the View/Modify soft key. The selected program appears on the LCD screen, as seen below.
4	Use the OK button to move between fields and use the Up and Down buttons to edit the values.
5	Press the Save → Main soft key to begin the selected interval program and return to the Line List display.
	Press the Prev Screen soft key to discard changes and return to the Cuff Interval screen.

5-6 Monitoring Blood Pressure

Continuous NIBP Monitoring

Sample Program

When you open programs A, B, C, or D for the first time, all of the program fields are blank. You can specify the length of each measurement period and the desired cuff interval for each measurement period, as seen in the following example.

INTERVAL PROGRAM A
RUN TIME: --
TIME (HH:MM)				INTERVAL
START		1:00		5 MIN
1:00		2:00		15 MIN
2:00		4:00		30 MIN
4:00		6:00		60 MIN
6:00		--		90 MIN
			11:06
PREV				SAVE
SCREEN				->MAIN

In this example, Interval Program A has five defined measurement periods. The first measurement period is one hour long (Start – 1:00) during which NIBP measurements will be taken every 5 minutes. The second measurement period is also one hour long (1:00 – 2:00). During the second measurement period, NIBP measurements will occur every 15 minutes.

Run Time is not defined in Interval Program A. This particular program will run indefinitely because the last measurement period contains a "--" to indicate that measurements should continue until explicitly stopped by the user. If a program contains specific beginning and ending times, the total duration of the program will appear in the Run Time field at the top of the screen.

Valid Values

Start times and end times can be any five-minute increment between 00:05 and 12:00. End times can also be "—" which indicates that the test will run indefinitely.

Up to five measurement periods can be defined in one program.

The possible selections for this value are: "—" (this selection indicates that this period will continue for eternity) and 0:05 – 12:00 (a time selection, in five minute increments).

The Cuff Interval value can be any of the following: OFF, STAT, 1, 2, 2.5, 3, 5, 10, 15, 20, 30, 60, 90, 120, and 180 minutes. The selected interval must be shorter than the measurement period.

If an Interval program is in progress when a user enters the screen, the cursor will identify the current point in time in that program. If no program is running, the cursor will appear next to the first time frame. You cannot make changes while a program is in progress.

Monitoring Blood Pressure 5-7

Continuous NIBP Monitoring

While the program is running, the letter identifying the program and a number identifying the current cuff interval appears on the Line List display under the word “Cuff.” For example, “A-5” indicates that program A is running and a cuff interval of 5 minutes is in process.

Stopping Interval Measurements

To inactivate all interval settings, press the Stop Program soft key in the Cuff Interval screen. The Interval setting changes to Off.
