READY FOR USE INDICATOR

READY FOR USE

INDICATOR

The Ready For Use (RFU) indicator is located on the upper, right corner of the device. It indicates the status of the therapy delivery functions of the monitor/ defibrillator using the following definitions:

A blinking black hourglass symbol indicates the shock, pacing, and ECG functions of the device are ready for use. Sufficient battery power is available for device operation.

A blinking red “X” and a periodic audio chirp indicate no battery is present or a low battery condition. If a battery is inserted and charging, the audio chirp is not present.

A solid red “X” and a periodic audio chirp indicate a failure has been detected that may prevent the delivery of a shock, pacing, or ECG acquisition. An error message will display at power-on.

A solid red “X” without periodic audio chirps indicates either there is no power available, or a device failure has occurred. If, after power is supplied, the indicator reverts to the blinking black hourglass symbol, the device is once again ready for use.

MONITORING SpO

Applying the Sensor

Follow the manufacturer's directions for applying and using the sensor, making sure to observe any warnings and cautions. For best results: Make sure the sensor is dry. If the patient is moving, secure the sensor cable loosely to the patient. Make sure the transducer is not too tight. Keep power cables away from the sensor cable and connections. Avoid placing the sensor in an environment with bright lights. If necessary, cover the sensor with opaque material. Avoid placing the sensor on an extremity with poor perfusion.

Monitoring SpO

1. Connect the appropriate sensor cable to the HeartStart MRx.

2. Apply the sensor to the patient.

3. If the HeartStart MRx is not turned on, turn the Therapy Knob to Monitor.

The pleth wave appears after a few seconds, followed by the oxygen saturation value. As the patient's oxygen saturation changes, the SpO2 value is continuously updated and the associated waveform is displayed. See the Alarms Quick Card for information on adjusting alarms.

Scrolling

LEFT/RIGHT: Use the << or >> soft keys to scroll left and right (backward/ forward) in the report screen. The soft key will be inactive if there is no more data to be viewed in that direction. UP/DOWN: If there are more vital signs than can be shown on the screen, use the Navigation buttons next to the Menu Select button to scroll up and down with the vertical scroll bar on the display. (Make sure there are no menu items active at the time.)

Reading Trending Data

- When trending is initially displayed, the latest (most recent) trending data will appear in the far right column; older data flows to the left.

- The display will auto-update as new data becomes available as long as the latest data is displayed on the screen.

- A -?- indicates that the parameter has invalid information.

- A ? just before a numeric value indicates questionable data.

- An empty space indicates unavailable data.

Printing the Vital Signs Trending Report

You can print the Vital Signs Trending Report two ways:

1. Press the soft key under the Print Trends label. A report for the displayed period and interval is printed.

2. Press the Summary button and select Trends and then Trends Interval. A report for the entire incident period is printed.

WEEKLY SHOCK TEST

How to perform the Weekly Shock Test

Test each type of patient therapy cable used (multifunction electrode pads or paddles). If you are using paddles, make sure the paddles are secure in their pockets and that the Patient Contact Indicator (PCI) LEDs located on the sternum paddles are not lit. If the LEDs light, adjust the paddles in their pockets. If the LEDs continue to light, clean both adult and pediatric paddle electrode surfaces. If you are using multifunction electrode pads, attach a test load to the end of the patient Therapy Cable.

1. Turn the Therapy Knob to 150J

2. Press the Charge Button. NOTE: If it becomes necessary to disarm the defibrillator, press [DISARM]

3. If using:

- Pads, press the Shock button on the HeartStart MRx to deliver a shock into the test load.

- External paddles, simultaneously press the shock buttons located on the paddles to deliver a shock into the test load.

4. The strip prints immediately if configured to do so. If the strip does not print immediately, press the Print button.

5. Confirm on the printed strip that the energy delivered to the test load is 150J +/- 23J (127J to 173J). If not, take the device out of use and call for service.
