Common failures and treatment measures of electrocardiograph

1. No ECG waveform output display and tracing. Treatment measures: 1 Check that each lead wire is in full contact with the electrode, and the conductive paste is evenly applied. 2 Check the connection of each lead, and confirm that the connection is correct after contacting the EEG machine to check the machine failure.

2. After pressing the START button, the paper speed is very fast, and the switch to switch the paper speed is invalid. Remedy: If the machine is faulty, please contact the equipment maintenance.

3. The stylus has high-frequency jitter, and the electrocardiogram cannot be recorded. Pressing the EMG and HUM function switches does not work. Treatment measures: 1 Check that the skin is in full contact with the electrode, and the conductive paste is evenly applied. 2 Patients with restless chills are assisted by family members.

4. Chest leads cannot be traced by a single lead. Remedy: Replace the lead description with other chest leads, and contact the instrument to repair the lead failure after the inspection.

Operation process of ECG monitoring defibrillator

1. Use things together to explain to the patient or family. Connect the power lead and turn on the power switch.

2. Clean and degrease the skin, and paste the electrode pads.

3. Connect the electrode pads to the monitoring leads and paste them on the corresponding parts to cover the patient with the quilt.

4. The ECG waveform appears on the oscilloscope screen, select the monitoring lead, adjust the amplitude of the ECG waveform, and select the alarm range.

5. Patients with ECG oscilloscopes who develop ventricular fibrillation should be defibrillated immediately, and choose asynchronous defibrillation.

6. Assist the patient to lie down on the pillow, turn the selector switch to 200 joules, and press the button to charge. Put a shock pad on the apex and bottom of the heart, press the skin tightly, remind people around to give way, and discharge defibrillation.

7. Auscultate the heart immediately, observe the oscillographic ECG activity, and trace the electrocardiogram. When ineffective, electric shock defibrillation can be repeated, and the maximum energy is 360 joules.

8. After successful cardioversion, wipe the patient's skin clean, dry the electric shock plate and place it in the plate groove. The EEG machine covers the patient with quilts and organizes things.
