    Maintenance Introduction This chapter describes routine maintenance on the HeartStart MRx monitor/defibrillator. Most routine maintenance, including periodic operational checks, paper replacement, lithium ion battery maintenance and charge, etc. is performed by the user. Refer to the Instructions for Use for detailed information on these maintenance procedures.
  • Page 24: Nbp Module Calibration

    2: Maintenance NBP Module Calibration NBP Module Calibration This section describes how to calibrate the HeartStart MRx NBP module. To calibrate the HeartStart MRx NBP module you need: • A manometer and cuff assembly or 500 ml expansion chamber. These instructions refer to the cuff assembly, but can be used with the expansion chamber as well.

    NBP Module Calibration 2: Maintenance Figure 10 NBP Calibration Setup Container Loosely fitted cuff Manometer Pump NBP Safety Features The NBP module is equipped with the Timeout and Overpressure safety features that prevent injury to the patient and damage to the device. NBP Timeout The NBP module times out when the pressure remains greater than 10 mmHg for 3 minutes.
  • Page 26: Nbp Calibration Procedure

    2: Maintenance NBP Module Calibration NBP Calibration Procedure Complete the calibration process within three minutes to avoid the NBP module timeout. To calibrate NBP: Calibrate Press the softkey. Apply 0 mmHg. Select Next when ready The message is displayed. Release all of the pressure in the cuff so that the manometer reads 0 mmHg. Next Press the softkey.
  • Page 27: Nbp Module Tests

    NBP Module Tests 2: Maintenance NBP Module Tests Perform NBP Module Tests only if there is an uncertainty about the module performance. Each of the procedures assumes the monitor/defibrillator, the manometer, and the cuff assembly are still set up as they were at the end of the previous test. If all results are as described, the device passes that portion of the test.

  • Page 36: Pump Check

    2: Maintenance EtCO Module Checks Pump Check This test checks the ‘strength’ of the pump by occluding the inlet and measuring how deep a vacuum the pump can pull. NOTE: The tests must be conducted in the order they are described here. For example, if you perform the Pump Check, and there is a leak that you have not found because you did not perform the Leakage Check, it may appear that the device has a faulty pump, when in fact it has a loose tubing connection.

Wait until the displayed CO value is stable. Check the noise index reading. If the noise index exceeds 3 mmHg, the CO module must be replaced.
  • Page 38 2: Maintenance EtCO Module Checks For example: [±0.05] × [36.8 mmHg] = ±1.8 mmHg In this example, the reading displayed with 5% cal gas must be 36.8 mmHg ±1.8 mmHg, or between 35.0 mmHg and 38.6 mmHg. Compare the displayed CO value to the allowable range of values.
