    SECTION 4. FUNCTIONAL DESCRIPTION The DINAMAP™ Portable Monitor, Model 8100, is a fully portable, microprocessor controlled, noninvasive device that automatically measures systolic pressure, diastolic pressure, mean arterial pressure (MAP), and pulse rate for neonates, children, and adults using the oscillometric technique.

  • Page 29: Determination Sequence

    DETERMINATION The monitor deflates the cuff one step each time it detects S E Q U E N C E two pulsations of relatively equal amplitude. Time between Continued deflation steps depends on the frequency of these matched pulses (pulse rate of patient). However, if the monitor is unable to find any pulse within 1.6 seconds, it deflates to the next step.

  • Page 35: Installation And Initial Setup

    INSTALLATION AND Electrical and Hose Connections INITIAL SETUP If there is no apparent external damage to the monitor, follow these steps. With monitor power off: 1. Check the voltage rating stamped on the serial number plate attached to the bottom of the monitor and make sure it matches the line voltage of the receptacle to be used.

    NEONATE ADULT/PEDIATRIC Figure 5-1. Recommended Cuff Placement WARNING 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. 5. Measure the limb of the patient and select the proper cuff size according to the size marked on cuff or cuff package.
  • Page 37 6. Connect the cuff to the hoses. Thread the cuff connectors onto the hose connectors. DO NOT OVERTIGHTEN. WARNING It is mandatory that the 8-foot hose (Light Blue, Reorder No. 8840) be used with neonatal cuffs and the 12 or 24 ft. hoses (Blue, Reorder No.

  • Page 38: Operating Warnings, Precautions, And Notes

    Vital signs may very likely be inaccurate if you use cuffs, hoses or accessories other than those provided by Critikon Company, LLC. The monitor will not operate effectively on patients who are experiencing convulsions or tremors.
  • Page 39 PRECAUTIONS Cont. Place the monitor on a rigid, secure surface or attach securely with the pole clamp. If the integrity of the electrical ground is in doubt, disconnect the power cord from the power source, and operate the monitor using internal battery.

  • Page 40: Operating Procedures

    PRECAUTIONS Cont. The pulse rate displayed by the DINAMAP™ Monitor may differ from heart rate displayed by an ECG monitor because the DINAMAP™ Monitor measures actual peripheral pulse. Occasionally, electrical signals at the heart do not produce a peripheral pulse. Similarly, if a patient's beat-to-beat pulse amplitude varies significantly (e.g., pulsus alternans, atrial...

  • Page 47: Troubleshooting

    TROUBLESHOOTING The DINAMAP™ Portable Monitor Model 8100 has been designed to provide safe and reliable operation in medical environments. As with all medical devices, if the accuracy of any determination value is questionable, first check the patient's vital signs by alternate means and then check the monitor.

  • Page 48: Excess Determination Time Alarm (844)

    TROUBLESHOOTING Excess Determination Time Alarm (844) Cont. This alarm is indicated by an alarm tone and a flashing 844 in the PULSE display. The alarm is generated if determination time exceeds 120 seconds, which is usually caused by excessive patient movement and/or erratic pulse rate.

  • Page 49: Monitor Will Not Power-On

    Monitor Will Not Power-On This condition could be caused by a depleted battery. Check fuse. Attach unit to AC power source. If problem persists, refer to qualified service personnel. Monitor Displays Extremely High Readings This condition could be caused by using a cuff that is too large or by the cuff being positioned above heart level.

  • Page 50: Maintenance And Calibration

    SECTION 6. MAINTENANCE AND CALIBRATION MAINTENANCE Cleaning The only maintenance routinely required is that the monitor and accessories are kept clean and are handled and used according to the instructions provided here and in the Service Manual (328-370). The exterior of the monitor may be wiped clean with a cloth slightly dampened with mild detergents.

  • Page 51: Battery Charging

    MAINTENANCE Battery Charging Continued To charge battery simply attach AC line power cord to the monitor's rear panel line power connector THEN plug the opposite end into an appropriate AC receptacle. The battery will charge regardless of the position of any other switches (see following table for battery charging characteristics).

  • Page 52: Battery Removal And Replacement

    Battery Removal and Replacement It is best to keep the battery charged as fully as is practical and never store the monitor with the battery in a discharged condition. When the battery will no longer take a charge, remove it and replace it with one of the same part number (320-378) as outlined below.

  • Page 53: Replacement Of Line Power Fuses

    Figure 6-1. Cover Removal Changing Fuses The monitor contains three fuses. Two AC line power fuses are contained in the power entry module. One battery fuse is contained on the power supply board and is accessible only by qualified service personnel. Replacement of Line Power Fuses At the rear of the monitor, remove the power cord (if one is attached).
  • Page 54 MAINTENANCE Continued Figure 6-2. Open AC Line Fuse Compartment Using the same tool, pry out each fuse holder as shown in Figure 6-3. Figure 6-3. Remove Fuse Holder Remove each fuse from its fuse holder as shown in Figure 6-4. and inspect it for a burned or broken filament. If the filament appears to be intact, check it for continuity with an ohmmeter.

  • Page 55: Replacement Of Battery Fuse

    MAINTENANCE Continued Figure 6-4. Remove Fuse From Fuse Holder Replace the fuse and fuse holder as shown in Figure 6-5. Make sure that the arrows on the outward facing ends of the fuse holders are pointing in the same direction as the arrows on the inside of the cover plate.

  • Page 56: Calibration Check Setup

    CALIBRATION Calibration of the monitor should be checked at least once a year or when there is doubt about the validity of the pressure readings. CAUTION Calibration equipment should always be kept dry and free of particulate matter. Moisture or foreign substances introduced into the pneumatic system can cause damage to the unit.
  • Page 57 BLOOD PRESSURE To perform a calibration check, follow these procedural CALIBRATION CHECK steps: Continued 1. Obtain the calibration kit (Reorder No. 8886) supplied with the unit. 2. Connect a mercury manometer (Baumanometer 300, or equivalent) to the monitor using the parts supplied with the calibration kit as shown in Figure 6-6.
