The device provides a voice prompt to guide you in applying electrodes to the patient.

Remove all clothing from the patient's chest, turn on the electrodes, and apply them to the patient's bare chest as shown.

Note: If the electrodes are not connected to the patient after several voice prompts, the device will automatically switch to CPR. See Chapter 8 and the Appendix for details.

When the electrodes are properly applied to the patient, the cardiopulmonary resuscitation commands will be immediately interrupted and the system will switch to rhythm analysis.

Note: The following electrodes should be used for defibrillation.

warn

If the electrodes are not applied correctly, the ECG signal may not be able to be analyzed. In this case, the device will provide a voice prompt:

To avoid the risk of skin burns from damaging the gel layer of the electrodes.

Before connecting the electrodes to the patient, be careful not to touch the gel layer. Caution: damage to the gel layer may cause skin burns.

cautious

Do not use expired or damaged electrodes, including damaged electrode bags.

Check validity from the expiration date.

7.5 Perform electrocardiogram analysis

If electrodes are used, the device will automatically begin rhythm analysis.

The patient should be placed in a stable location and should not be touched. The device will provide voice prompts:

The device's algorithm will assess whether a patient's electrocardiogram (ECG) signal requires defibrillation.

If the device detects external interference (e.g., shaking the patient, etc.) affecting the ECG signal, the device will provide a voice prompt:

Do not touch the patient if movement is detected.

During the heart rhythm analysis process, the system first filters the original acquired electrocardiogram signal to remove low-frequency baseline drift and high-frequency noise interference, and then further eliminates interference that may be generated in the signal, including patient tremors, breathing, muscle contractions, etc.

Note: The electrocardiogram displayed on the monitor is for identifying the application of electrodes, not for diagnostic purposes.

7.6 Defibrillation

Note: An impact will only be emitted when the impact button is lit and pressed. (For semi-automatic models)

Defibrillation may cause muscle contractions in the patient.

When the device is charged and ready to withstand an impact:

If the device detects a shock-prone rhythm, it will not discontinue defibrillation.
If the device detects a non-impact rhythm, it will automatically terminate the defibrillation process.

If the device can clearly identify VF, it will recommend defibrillation.

Press the impact button promptly according to the voice command.

myPAD Fully Automated External Defibrillator

Do not touch the patient; the electric shock will occur at the count of "three," "two," "one."

The impact is delivered automatically, requiring no further action.

Following a shock delivery, the device will continue to provide cardiopulmonary resuscitation (CPR) guidance until the next electrocardiogram analysis.

Defibrillation and cardiopulmonary resuscitation will be repeated according to the instructions in the ERC guidelines.

If the device can't find a shocking rhythm, then you'll hear:

Danger

Dangers to users or third parties

Triggered arrhythmias

Before and during defibrillation, all resuscitation participants must stand still and avoid contact with the patient or other potential electrical conductors (e.g., the stretcher).

7.7 Cardiopulmonary Resuscitation (CPR)

The device follows the recommendations of the 2021 ERC guidelines. These guidelines differentiate resuscitation methods for trained and non-trained rescuers. Chest compressions should be performed on a hard surface whenever feasible.

7.7.1 Cardiopulmonary resuscitation by trained rescuers

The 2021 ERC guidelines recommend that trained first responders perform two ventilations after chest compressions. For trained first responders, different procedures are recommended for adults and children. For adults, ERC 2021 recommends alternating 30 chest compressions and 2 ventilations. For children, ERC 2021 recommends alternating 15 chest compressions and 2 ventilations.

In child mode, we provide 15 to 30 chest compressions followed by 2 breaths. To change the configuration, please contact your dealer or our service.

Adult Mode

Sub-pattern

7.7.2 Cardiopulmonary resuscitation (CPR) for non-professional rescuers

According to the ERC 2021 guidelines, untrained adult first responders are advised to perform only continuous chest compressions without ventilation during resuscitation. If the first responder has not received specific training in pediatric basic life support, the ERC 2021 guidelines recommend two chest compressions and two ventilations or continuous chest compressions for children.

Adult Mode

Sub-pattern

7.7.3 CPR Configuration of the Equipment

The default CPR configuration is described in Chapter 7.7.1. For changes to the chest compression device configuration, please refer to Chapter 7.7.2. Contact your dealer or our service department.

7.7.4 CPR Metronome Function

During chest compressions, the device provides a metronome function to guide you in performing the correct chest compression rate. Please follow the rhythm.

For the equipment configuration described in Chapter 7.7.1, artificial respiration is also guided by two acoustic outputs.

Note: Once a cardiopulmonary resuscitation cycle is completed, the device begins another cardiac rhythm analysis.

Cardiopulmonary resuscitation (CPR) should always be performed until emergency services arrive.

7.7.5 CPR Feedback Sensor

This chapter applies only to electrodes with CPR feedback sensors.

When connected to a CPR feedback sensor, the device provides voice prompts about real-time compression feedback.

During chest compressions, the device will provide compression quality feedback in voice prompts when you use electrodes with CPR feedback sensors.

Note: Correction tips regarding chest compression depth are only applicable to adult patients in pediatric mode, providing feedback on CPR quality.

Connect CPR feedback sensor

Place the CPR feedback sensor so that the compression area is located in the middle of the chest, between the nipples.

Figure 15 CPR feedback sensor positioning

Recommended compression frequency: 100-120 / min

When the compression rate is less than 100 bps, a voice prompt will appear: <Press faster>
When compression exceeds 120 rpm, a voice prompt will appear: <Press slower>

Recommended compression depth for adults: 5-6 cm

When the compression depth is less than 5 cm, the voice prompt will say "<Press harder>".
When the compression depth is greater than 6 cm, the voice prompt will say "Press lightly".
