WARNING

As with electronic equipment, Radio Frequency (RF) interference between the defibrillator and any existing RF transmitting or receiving equipment at the installation site, including electrosurgical equipment, should evaluated carefully and any limitations noted before the equipment is placed in service Monitoring during quiescent periods of electrosurgery is possible but electromagnetic interference generated by electrosurgical tools during operation is sufficient to mask cardiac signals. A momentary recovery period is required for the monitor to return to normal operation and will be longer if the diagnostic monitoring mode is used. Pads or electrodes should be placed as far from the surgical area as reasonable while still performing normal function to minimize the possibility of burns. Radio frequency generation from electrosurgical equipment and close proximity transmitters may seriously degrade performance of the CodeMaster XL+ defibrillator/monitor.

Press and briefly hold both Shock buttons (one on each paddle) simultaneously, to deliver energy to the patient.
If the defibrillator does not shock, refer to Chapter 8, Troubleshooting.
If you must disarm the charged defibrillator (if countershock is not needed), turn the Energy Select control to Monitor On. Any stored energy will be discharged internally and the available energy on the display will return to 0.
After Using the Defibrillator
If installed, if you want to print an Event Summary now, press. See Printing the Event Summary Record (Optional) on page 3-8. After you use the defibrillator, perform the following steps to prepare the defibrillator for its next use.
Turn the Energy Select control to Off (Standby). Return the instrument to its storage location, and plug the power cord into an AC power outlet. Verify that the and lights are on.
Clean all paddles, controls, and cables. Refer to Chapter 9, Maintaining the Defibrillator for cleaning instructions. Check that sufficient recorder paper and electrolyte paste or defibrillator electrodes are available for the next use of the defibrillator.
Defibrillating with Alternate Paddle Sets
The CodeMaster XL+ will defibrillate with several different electrodes/paddles sets. Adult/Pediatric Anterior/Anterior External Paddles Anterior/Posterior Paddles External Multi-Function Defib Electrodes Internal Paddles
9vpuhqqyrrvhrvrurrhrhtrvur ryrpqrhqqyrprprprhpyr
Performing Pediatric Defibrillation The CodeMaster XL+ paddle set comes with pediatric paddles. To use the pediatric paddle set, depress the release latch at the front of the standard external paddle set while pulling forward on the adult paddle surface. This action will remove the adult paddle contact surface and expose the smaller pediatric contact surface. When
pediatric paddles are in use, the adult electrode plates may be conveniently stored in the paddle pockets of the defibrillator. Refer to Defibrillating a Patient on page 2-1 for defibrillation procedures.
Uurpyvvpvhryrphhvhrrrtyrrysurrqvhvp hvrUurrvrrtyvvypxsurrqvhvphqqyrr
Defibrillating through External Multi-Function Defib Electrodes The CodeMaster XL+ has an external electrodes adaptor that is optional. This adaptor allows defibrillation through external adhesive electrodes. External Electrodes have the following advantages. They allow "hands off" defibrillation. They provide good quality monitoring. You can perform synchronized cardioversion without using an ECG lead set, while monitoring through the electrodes. If the optional pacer is installed, you can switch between the pacing and defibrillation modes of operation quickly.

Using Leads to Monitor

The CodeMaster XL+s monitoring functions can be used for cardiac monitoring, elective cardioversion, and pacing (optional). Table 3-1, Cardiac Monitoring Configurations details the different ECG sources that can be used for cardiac monitoring and monitoring applications for which each is suited.

Printing the Event Summary Record (Optional)
During defibrillator usage, the monitor stores up to 28 ECG strips of critical information called events. Events include all shocks, heart rate alarm violations, SpO2 alarm violations and mark events. Each event record includes date of event, heart rate, ECG source, and size setting as shown in Table 3-6, Event Summary Record Information. The time annotated on the ECG strip is within 8 seconds of the recorded event. The message ES is printed at the top of the ECG strip when you print the Event Summary record.

The Event Summary record is cleared each time the defibrillator is turned off, then on and a new event occurs. This allows you to turn off the defibrillator and return later to review event information such as code statistics. Turn the defibrillator off between uses to ensure that Event Summary records are patient specific.

Recording

To print a record of the current ECG and of the monitor status, press
The upper line of the ECG strip contains a periodic report of monitor parameters (Date, Time, Heart Rate, ECG Source, ECG Size, and Recorder mode). The lower line of the ECG strip records asynchronous events such as Shock delivery or Heart Rate Alarm violations. Several graphic symbols are used to annotate events such as Shock, HR Alarms, Mark, or Sync. A 1 mV, 200 ms calibration pulse can be printed on the ECG strip by pressing both arrows on the key simultaneously.

To start cardioversion, perform the following steps. 3 Turn the Energy Select control to Monitor On. Select the desired ECG lead by pressing

Apply the paddles to the chest as follows. a. b. Place the Sternum paddle to the right of the sternum just below the clavicle. Place the Apex paddle on the chest just below and to the left of the left nipple, in the anterior-axillary line.
Verify again that the ECG waveform is stable, and that a marker dot appears only with each R-wave of the cardiac cycle. Rub the paddles lightly against the skin to distribute the electrolyte paste and increase the contact between the patient skin and the paddles.
Apply 10 to 12 kg (22 - 25 lb.) of pressure per paddle. Briefly adjust paddle pressure and placement to optimize contact, as registered on the paddle contact indicator. Press
on either the right (Apex) paddle or on the instrument front panel.
Wait for the Charge Done indicators.
If you must disarm the charged defibrillator (if counter shock is not needed), turn the Energy Select control to Monitor On. Any stored energy will be discharged internally and the available energy on the display will return to 0.
To increase or decrease the selected energy level after has been pressed, move the Energy Select control to the new energy level, and wait for the Charge Done indicators.

If the message NO PADDLES is displayed, check that the electrodes adaptor cable connector is properly seated and latched. If the message PADS OFF is displayed, check the electrodes connection to the patient and to the electrodes adaptor cable. Press to turn the pacer on. Pacer parameters will now be displayed at the bottom of the display (PACER STOP, DEMAND MODE, 70 PPM 30 MA). The rate (ppm) and output (mA) settings for when the pacer is turned on can be selected in setup menu 1. The original rate and output settings from the factory are 70 ppm and 30 mA. The pacer is always in Demand mode when it is turned on.
At this point, no pacer pulses are being delivered to the patient. The pacer must be started before the pacer pulses are delivered at the selected rate (ppm) and output (mA).
Press to select the best lead for monitoring while pacing. You can only select Leads as the ECG source when the pacer is on.

WARNING

As with electronic equipment, Radio Frequency (RF) interference between the defibrillator and any existing RF transmitting or receiving equipment at the installation site, including electrosurgical equipment, should evaluated carefully and any limitations noted before the equipment is placed in service Monitoring during quiescent periods of electrosurgery is possible but electromagnetic interference generated by electrosurgical tools during operation is sufficient to mask cardiac signals. A momentary recovery period is required for the monitor to return to normal operation and will be longer if the diagnostic monitoring mode is used. Pads or electrodes should be placed as far from the surgical area as reasonable while still performing normal function to minimize the possibility of burns. Radio frequency generation from electrosurgical equipment and close proximity transmitters may seriously degrade performance of the CodeMaster XL+ defibrillator/monitor. Hewlett-Packard assumes no liability for failures resulting from RF interference between HP medical electronics and any radio frequency generating equipment at levels exceeding those established by applicable standards. Classified by Underwriters Laboratories, Inc. with respect to electrical shock, fire, and mechanical hazards only in accordance with UL 2601-1.
Responsibility of Manufacturer
Hewlett-Packard only considers itself responsible for any effects on safety, reliability and performance of the CodeMaster XL+ defibrillator/monitor and the battery support system if: assembly operations, extensions, readjustments, modifications or repairs are done by persons authorized by Hewlett-Packard, and

This chapter covers setting up and configuring the CodeMaster XL+ Defibrillator/ Monitor. If you are a Hewlett-Packard service representative, this information provides a factory-recommended process to use when assisting customers. The configuration information guides you through the setup menus, and describes configuration choices.
The defibrillator is ready for operation when the following tasks have been properly performed:
Install battery. Charge battery (for 24 hours). Install paper. Make sure that the paddle set connector is seated and locked. Select configuration settings; set date and time.

Line Voltage Settings

The defibrillator automatically adjusts to the line voltage that is supplied (from 100230 VAC 15% at 50/60 Hz). No manual setting or adjustment is required.

If the defibrillator will be stored for longer than one month without AC power, remove the battery from the unit. Note on the instrument that the battery has been removed. After an extended storage period, the battery should be tested using the battery capacity check. See Chapter 3, Performance Verification and Maintenance.
2-4 May 17, 2000 4:04 pm DRAFT
Loading the Recorder Paper
The defibrillator recorder uses two-inch wide, thermal paper (40457C/D). To load the paper: 1 Slide the recorder door toward the right side of the defibrillator until the paper platen tilts up. 2 Pull up on the plastic removal tag to remove the old paper roll, if one is present. 3 Unroll about six inches of paper on the new roll; turn the paper roll so that the grid side of the unrolled paper is on the bottom (facing downward). 4 Place the roll of thermal paper in the recorder so that the grid side of the paper will face the print head in the recorder. 5 Pull the free end of the paper upward and over the recorder platen. (See Figure 2-3). 6 While holding the recorder door open (to the right), press the platen down to its normal (closed) position. 7 Release the recorder door, allowing it to close over the platen. 8 Place the free end of the paper on the left side of the recorder.

ECG Front End Board

Two separate and isolated front ends constitute the ECG front end board as shown in the block diagram in Figure 7-6. The first is a two-wire paddles ECG amplifier, and the second is a five-wire leads front end. The paddles front end operation is nearly identical to the leads front end operation. The design for both front ends is based on a HewlettPackard custom front-end IC. The paddles front end also includes functions for paddlesin-pocket and pre-shock impedance (also called paddles contact impedance or PCI).

Both front ends communicate with the Digital Signal Processor (DSP) located on the control board. The DSP processes the digitized data from both front ends simultaneously and provides data to the monitor processor.

Power Supplies

Each of the front ends has its own isolated power supply. The supply for the leads front end is enabled when the FELEN signal is true; the supply for the paddles front end is enabled when the FEPEN signal is true. A forward converter, which is clocked by FEPWRCLK, generates isolated power for the two front ends. The output of the converter is regulated to +5 volts. The supply also provides a 2.5-volt reference for use in biasing the front end IC.
