1 Powering the electrocardiograph The electrocardiograph runs on AC or battery power. Plug the electrocardiograph into AC power as often as possible so that the built-in charger can keep the battery charged. Regardless of the battery condition, you can use the electrocardiograph whenever it is plugged in. WARNING When you use AC power, always plug the electrocardiograph into a hospital-grade outlet to avoid the risk of shock.

3 Loading the thermal paper The electrocardiograph prints on z-fold thermal paper. • Store the paper in a cool, dry, dark place. • Do not expose it to bright light or UV sources. • Do not expose it to solvents, adhesives, or cleaning fluids. • Do not store it with vinyls, plastics, or shrink wraps.

5 Attaching the leads to the patient Proper lead attachment is important for a successful ECG. The most common ECG problems are caused by poor electrode contact and loose leads. Follow your local procedures for attaching the leads to the patient. Here are some common guidelines. WARNING Electrodes can cause allergic reactions. To avoid this, follow the electrode manufacturer’s directions. To attach the leads to the patient 1. Prepare the patient. • Describe the procedure.
6 Attaching the leads to the patient CP 150 12-lead resting electrocardiograph Electrode examples, left to right: arm clamp (reusable), Welsh cup (reusable), tab electrode (disposable), monitoring electrode (disposable). • For reusable electrodes: Use electrode paste, gel, or cream to cover an area the size of each electrode but no larger. Secure the arm and leg clamps. Apply the Welsh cups (suction electrodes) to the chest.
7 ECG home screen The ECG home screen includes the following areas: Item Area 1 Device status 2 Content 3 Navigation Device status area The Device status area, located at the top of the ECG home screen, displays: • Time and date • Battery status • Error or information messages. These items are displayed until the condition has been resolved.
8 ECG home screen CP 150 12-lead resting electrocardiograph • Auto ECG • Rhythm ECG • Stat ECG • Electrode Placement The content area also provides shortcuts to several controls. Navigation area The Navigation area includes the following tabs: • ECG home: Displays ECG test types and provides shortcuts to several controls. • Saved tests: Accesses the patient ECG tests. • Settings: Accesses device configuration settings.
9 About the test types Auto ECG A report typically showing a 10-second acquisition of 12 leads of ECG information combined with patient data, measurements, and optional interpretation. Auto ECGs can be saved to the electrocardiograph’s test directory or to a USB mass-storage device. Rhythm ECG A continuous, real-time printout of rhythm strips with a user-defined lead configuration. Rhythm ECGs are printouts only. They cannot be saved.
10 About the test types CP 150 12-lead resting electrocardiograph
11 Performing an Auto ECG test CAUTION Patient data is not saved until the ECG test is completed. The ECG configuration settings can be changed in the Settings tab. The following settings may appear differently if the default settings have been modified. Note 1. Touch the (Auto ECG) button. The Summary tab appears. 2. (Optional) Search for patient. The Search tab gives you access to patient data in the Saved tests directory or in a connected database (CardioPerfect workstation or EMR).
12 Performing an Auto ECG test CP 150 12-lead resting electrocardiograph • Height. Touch the OK button. • Weight. Touch the OK button. 6. Touch the (Next) button. 7. Attach the leads to the patient. Note If the lead-status screen is closed, touch the button to enlarge the lead-status screen. (torso) Any flashing dots on the lead-status screen indicate unattached or poorly attached leads. When all leads have been attached for several seconds, the ECG preview screen appears.

You might need to ensure that the patient is comfortably warm, reprepare the patient’s skin, use fresh electrodes, or minimize patient motion. 9. (Optional) Adjust the waveforms, using the buttons to cycle through the following options: • leads displayed • gain (size) • speed • filters 10. Touch the Print button to perform the Auto ECG test. 11.

15 Troubleshooting Lead-quality problems “Artifact” message on the screen Artifact is signal distortion that makes it difficult to accurately discern the waveform morphology. Causes • The patient was moving. • The patient was shivering. • There is electrical interference. Actions See actions for wandering baseline, muscle tremor, and AC interference. Wandering baseline Wandering baseline is an upward and downward fluctuation of the waveforms.
16 Troubleshooting CP 150 12-lead resting electrocardiograph Muscle tremor Causes • The patient is uncomfortable, tense, nervous. • The patient is cold and shivering. • The exam bed is too narrow or short to comfortably support arms and legs. • The arm or leg electrode straps are too tight. Actions • Verify that the patient is comfortable, warm, and relaxed. • Check all electrode contacts. • If interference persists, turn the muscle-tremor filter on.
Quick reference guide Troubleshooting 17 Lead alert or square wave A dot might be flashing on the lead-status screen. Or one or more leads might appear as a square wave. Causes • Electrode contact might be poor. • A lead might be loose. • A lead might be defective. Actions • Replace the electrode. • Verify that the patient’s skin has been properly prepared. • Verify that electrodes have been properly stored and handled. • Replace the patient cable.
18 Troubleshooting CP 150 12-lead resting electrocardiograph • Recharge the battery. • Replace the battery. The electrocardiograph prints fewer than 10 reports on a full battery charge Causes • The battery is degraded. Actions • Replace the battery. The electrocardiograph does not respond when you press buttons or touch the screen Causes • The electrocardiograph is frozen.
