Introduction

About the DINAMAP Compact Monitor

DINAMAP Compact Monitors provide noninvasive determination of systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse rate, temperature, and oxygen saturation. These portable AC- and DCoperated monitors are primarily intended for use in hospital acute care settings such as outpatient surgery, accident and emergency, labor and delivery, GI/endoscopy, and medical/ surgical units.

The DINAMAP Compact Monitor comes in four different models: Models T, S, TS, and BP, with and without printers.

• Model T: BP, Pulse, and Temp

• Model S: BP, Pulse, and SpO

• Model TS: BP, Pulse, Temp, and SpO

• Model BP: BP and Pulse

All of the main operations of the DINAMAP Compact Monitor are easy to use and, in most cases, the factory default settings will be suitable. The “Using the Monitor” section of this manual explains how to use the system in its most simple form, while the “Using the Menu System” section explains how to customize measurements by using the menu system.

Indications

The DINAMAP Compact Monitor is intended to monitor one patient at the bedside.

Getting Started

Unpacking the Monitor and Accessories

Before attempting to use the DINAMAP Compact Monitor, take a few minutes to become acquainted with the Monitor and its accessories. Unpack the items carefully, and check them against the contents checklist enclosed in one of the accessory boxes. This is also a good time to check for any damage or shortage. If there is a problem or shortage, contact Critikon.

It is recommended that all the packaging be retained, in case the Monitor must be returned for service in the future.

Power Sources

The DINAMAP Compact Monitor is designed to operate from either an internal lead-acid rechargeable battery or an external AC source via the AC-DC power converter supplied with the Monitor. For replacement power converters or rechargeable batteries, please refer to Appendix D.

For continued safety, use only the double-insulated AC-DC power converter supplied with the Monitor.

The external DC line power input is protected by an internal

3.15 Amp fuse, type T3.15A, which can be accessed from the rear panel. The internal battery power source is protected by a resettable thermal fuse.

Powering the Monitor

Before the DINAMAP Compact Monitor is used for the first time, the battery should be charged in the Monitor for at least 24 hours.

Refer to the illustration of the rear panel connections. Looking at the rear of the DINAMAP Compact Monitor , remove the battery compartment cover (2). Insert the rechargeable battery pack into the compartment so that the battery terminals fit into the power clips at the bottom of the compartment. Then replace the cover. Insert the plug from the AC-DC power converter into the external power socket (3) and plug the converter into an AC outlet. Refer to the illustration of the front panel controls and indicators. With external power connected, the green external power indicator LED (7) will light to indicate that

external power is being applied and that the battery is charging. If the battery is not inserted, the external power indicator LED will flash. When the Monitor is running on battery power, a battery icon appears in LCD area 3 (toggling with the time indicator) indicating the charge status.

During battery-only operation, the yellow battery power indicator LED (8) will light. When the battery becomes discharged and only 10% of the full charge remains, the indicator will begin to flash and the Monitor will sound periodic warning beeps. At this point, the Monitor should be connected to an AC outlet to recharge the battery. If the Monitor continues to be used without charging the battery, the message WARNING: THE BATTERY IS TOO LOW FOR MONITOR TO FUNCTION. TURN MONITOR OFF appears, and the Monitor will enter the fail-safe mode. The fail-safe mode shuts down all functions until the Monitor is turned off and the battery is recharged or replaced.

Battery charging will take place as long as the Monitor remains connected to an external AC power source via the supplied AC-DC power converter. A battery that is fully discharged can be fully recharged in 1 hour 50 minutes when the Monitor is switched off or 8 hours if the Monitor is switched on.

Notes

• To prolong the life of the battery, keep the Monitor connected to an AC outlet whenever possible. NEVER allow the battery to become completely discharged. A fully charged battery will power the Monitor for approximately 3 to 4 hours (Model TS and T with printer: 3 hours. Model BP and T with printer: 4 hours.) and should survive between 200 and 500 charge/discharge cycles. When it is necessary to replace the battery, refer to the Compatibility Table and Reorder Codes listed in Appendix D. To ensure full charge cycles, replace only with a recommended battery. If the Monitor is to be stored for some time, first charge the battery and then remove it and store it separately from the Monitor.

• For continued safety, use only a power cord of listed type SJT, three-conductor, min. No. 18 AWG, terminated in a hospital grade attachment plug, provided with the

Getting Started

following cord tag: “Hospital Grade Plug." Grounding integrity can only be maintained when equipment is connected to an equivalent receptacle marked "Hospital Grade."

• Where the integrity of the external earth conductor in the installation or its arrangement is in doubt, the Monitor must be operated from its internal battery.

Getting Started

Installing the Temp Probe Holder

Attach the temperature probe holder to the side of the DINAMAP Compact Monitor (Models T and TS) by aligning the back and bottom edges of the holder and the Monitor and pressing the holder firmly to the Monitor.

A distinct snap will sound when the Dual LockTM fasteners are properly engaged.

To remove the holder, place your fingers in the indentations at the back of the Monitor and pull the holder away from the side of the Monitor.

Switching the Monitor On and Off

To switch the DINAMAP Compact Monitor on, push the power on/off switch (6) or click the SelectKnob (9).

As the Monitor powers up, it will run a short self-test routine, which will flash all the indicator lights and then beep the warning speaker. After a few seconds the system will be ready for operation, as indicated by the appearance of the main menu on the LCD (10).

To switch the Monitor off, push the power on/off switch (6) again. This will terminate any measurements that may be in progress and automatically deflate the cuff.

When the Monitor is operating on the internal battery only, battery life is enhanced by the use of the sleep mode. However, the Compact Monitor will not enter sleep mode if an alarm is active. If no controls are used and no

Getting Started

Using the Printer

Installing the Paper (Models With Printer)

Tilt the DINAMAP Compact Monitor back and grasp the tabs at the sides of the printer door (26). Squeeze the tabs together and pull the printer door down. Place the roll of paper into the compartment so that the end of the paper comes off the top of the roll and extends approximately 1 inch (2.5 cm) beyond the roller at the front edge of the door. There is no need to thread the paper; it simply rests over the rubber roller. Note: Make sure that the roll of paper is tightly wound.

With the Monitor powered on, snap the printer door shut, leaving a small amount of paper exposed. The printer motor will feed a little paper forward and out over the door.

Any time the printer door is opened or closed the printer will automatically print a test strip with the DINAMAP Compact name on it. If no print is visible on the paper, check that the paper roll has been installed correctly. The paper should be coming off the top of the roll. To tear off the printout, use a slight sideways action to pull the paper sharply down across the serrated edge of the door.

Printer Alarms

If the Monitor is switched on with no paper installed or with the printer door open, the message “No Paper” will appear next to “PRNT” in Area 3 of the LCD. When new paper is installed and the printer door is closed, the message will change to “Man” for Manual print or “Auto” for Auto print, depending on the status before the paper change.

If the paper runs out during a print request or if an attempt is made to print when no paper is installed, the message

“Printer - No Paper” will appear in Area 2 of the LCD and an audible alarm will sound. In addition, the message “No Paper” will appear next to “PRNT” in Area 3 of the LCD. To clear the alarm, press the SelectKnob. The message in Area 3 of the LCD will remain until new paper is installed and the printer door is closed. (See “Using the Menu System.”)

Installing new paper will cause the Critikon DINAMAP Compact header to be printed, thereby confirming that the paper is installed correctly and that the printer is operational. The message next to “PRNT” in Area 3 of the LCD will change to “Auto” or “Man” to identify the operating mode of the printer. After power-off, the operating mode of the printer returns to the previous user-selected setting (Auto or Man) unless specified otherwise in the Print button under the Service Button.

Cleaning

If the print quality is reduced, the print head can be cleaned with a cotton swap saturated with isopropyl alcohol. For preventive maintenance, clean the print head once a month.

Storage

Store thermal paper in a cool, dry place. The printed strip (thermal paper recording) should not be

• exposed to direct sunlight,

• exposed to temperatures over 100 ˚F/38 ˚C or relative humidity over 80%, or

• placed in contact with adhesives, adhesive tapes, or plasticizers such as those found in all PVC page protectors.

Note: When in doubt about long-term storage conditions, store a photocopy of the thermal paper recording.

Cautions

•The paper is thermally activated; therefore, do not store it in a hot place as discoloration may result.

•Only use replacement paper rolls from Critikon.

Using the Monitor

Noninvasive Blood Pressure Determination

Description

The BP parameter is included in Models T, S, TS, and BP. Blood pressure is monitored noninvasively in the DINAMAP Compact Monitor by the oscillometric method, which measures the amplitude of the pressure oscillations within the blood pressure cuff. Further information about the oscillometric method is in Appendix C.

The Compact Monitor has four BP modes: 1. Manual,

2. Auto, 3. Stat, and 4. Vitals. The mode, which is selected by the user, is shown on the LCD (10). The BP measurements are automatic, and once the cycle is complete the LED displays (14, 15, 16, 18) will show systolic pressure, diastolic pressure, mean arterial pressure, and pulse rate.

1. Manual BP determinations are started by pressing the BP key (12). In the Manual mode, the blood pressure is

determined one time.

2. If the Quik BP menu is enabled (Refer to “Quik BP” in the “Using the Menu System” section.), Auto BP determinations are started by selecting the Auto button. If the Quik BP menu is disabled, Auto BP determinations are started by selecting the Auto button under the Set BP button in the Main menu.

When Auto mode is selected, a number at the right of

the Auto button indicates the time interval between each reading. To change the time interval, choose the box around the number and turn the SelectKnob until the desired interval is reached. The interval can be set between 1 and 90 minutes (1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 45, 60, and 90 minutes). Press the SelectKnob to confirm the setting.

3. Stat determinations are started by pressing the Stat key (13). In the Stat mode, the blood pressure is determined as many times as possible in 5 minutes.

4. Vitals determinations are started by selecting the Vitals button in the Main menu. (Refer to the “Using the Menu System” section.) Selection of this button initiates BP, SpO2, and predictive temperature determinations (depending on Monitor model). In the Vitals mode, the blood pressure is determined one time.

Before each BP determination, the Monitor performs a test to ensure that the cuff pressure is below a specified level. The determination is delayed until this condition is met. During the delay, the BP values are displayed as zero.

The Monitor senses the type of hose being used and automatically uses adult/pediatric monitoring parameters or neonatal monitoring parameters, as appropriate.

Audible and visible alarms occur when a value for systolic pressure, diastolic pressure, mean arterial pressure, or pulse rate is outside the selected high or low limit.

Instructions for cleaning and disinfecting BP cuffs are in Appendix F.

General Warnings

• The Compact Monitor will not measure blood pressure effectively on patients who are experiencing seizures or tremors.

• Arrhythmias will increase the time required by the Compact Monitor to determine a blood pressure and may extend the time beyond the capabilities of the Monitor.

• In Manual mode, the Compact Monitor displays the results of the last blood pressure determination for 2 minutes or until another determination is completed. If a patient’s condition changes between one determination and the next, the Monitor will not detect the change or indicate an alarm condition.

• Devices that exert pressure on tissue have been associated with purpura, skin avulsion, compartmental syndrome, ischemia and/or neuropathy. To minimize these potential problems, especially when monitoring

Using the Monitor

at frequent intervals or over extended periods of time, make sure the cuff is applied appropriately and examine the cuff site and the limb distal to the cuff regularly for signs of impeded blood flow.

• Do not apply external pressure against cuff while monitoring. Doing so may cause inaccurate blood pressure values.

• Use care when placing cuff on extremity used to monitor other patient parameters.

• The Compact Monitor is designed for use only with dual-tube cuffs.

• Use only accessories recommended by Critikon. Failure to use recommended accessories may result in inaccurate readings. See Appendix D.

• Blood pressure cuffs should be removed from the patient when the Monitor is powered off. If the extremity remains cuffed under these conditions or if the interval between blood pressure determinations is prolonged, the patient’s limb should be observed frequently and the cuff placement site should be rotated as needed.

General Cautions

• Accuracy of BP measurement depends on using a cuff of the proper size. It is essential to measure the circumference of the limb and to select the proper size cuff. The air hoses are color-coded according to size of the patient. The gray 12- or 24-foot hose (3.66 m or 7.3 m) is required on patients who require cuff sizes from infant through thigh cuffs. The teal (bluegreen) 12-foot hose (3.66 m) is required for the neonatal cuff sizes #1 through #5.

• If it becomes necessary to move the cuff to another limb, make sure the appropriate size cuff is used.

• The pulse rate derived from a BP determination may differ from the heart rate derived from an EKG waveform because the Compact Monitor measures actual peripheral pulses, not electrical signals or

contractions from the heart. Differences may occur because electrical signals at the heart occasionally fail to produce a peripheral pulse or the patient may have poor peripheral perfusion. Also, if a patient’s beat-tobeat pulse amplitude varies significantly (e.g., because of pulsus alternans, atrial fibrillation, or the use of a rapid-cycling artificial ventilator), blood pressure and pulse rate readings can be erratic, and an alternate measuring method should be used for confirmation.

General Notes

• A patient’s vital signs may vary dramatically during the use of cardiovascular agents such as those that raise or lower blood pressure or those that increase or decrease heart rate.

• Because treatment protocols based on the patient’s blood pressure may rely on specific values and differing measurement methods, such as auscultatory, clinicians should note a possible variance from values obtained with the Compact Monitor in planning patient care management. The Compact Monitor values are based on the oscillometric method of noninvasive blood pressure measurement and correspond to comparisons with intra-aortic values within ANSI /AAMI Standards for accuracy (a mean difference of ± 5 mmHg, and a standard deviation of ± 8 mmHg).

• Several conditions may cause the BP parameter to calculate and display only the mean arterial pressure (MAP) without a systolic and diastolic reading. These conditions include very low systolic and amplitude fluctuations, so an accurate calculation for these values can’t be made (e.g., patient in shock); too small of a difference between systolic and MAP calculations in relationship to the difference between diastolic and MAP; or a leak has occurred in the DINAMAP Compact Monitor (1. Check all BP connections 2. Monitor may need calibration and leak testing). If only the MAP value is displayed, the systolic and diastolic will display dashes (---) and an alarm message “N99-BP FAILED” will be displayed.

Using the Monitor

Procedures

1. Connect the end of the air hose which has quick-release clips to the cuff connector (24) on the front of the Monitor. Make sure that the hose is not kinked or compressed.

Note: To disconnect the hose from the Monitor, squeeze

the quick-release clips together and pull the plug from the cuff connector (24).

2. Select the appropriate blood pressure measurement site. Because normative values are generally based on this site and as a matter of convenience, the upper arm is preferred. When upper arm size or shape, the patient’s clinical condition, or other factors prohibit use of the upper arm, the clinician must plan patient care accordingly, taking into account the patient’s cardiovascular status and the effect of an alternative site on blood pressure values, proper cuff size, and comfort. The figure shows the recommended sites for placing cuffs.

Warning: Do not place the cuff on a limb being used for intravenous infusion or any area where circulation is compromised or has the potential to be compromised.

Adult/Pediatric

3. If patient is standing, sitting, or inclined, ensure that cuffed limb is supported to maintain cuff at level of patient’s heart.
