How to use the defibrillator machine?

​

Defibrillators should be used by experts doctors or technicians,..etc. Defibrillators are the devices used to deliver shocks to the heart in cases of life threatening cardiac disorders. Electrodes that are connected to the machine are usually held in place over the chest of a patient while one or more shocks are delivered. Defibrillators are used to re-establish a normal heart rhythm in cases of cardiac arrhythmia, ventricular fibrillation and pulseless ventricular tachycardia.The chest of the patient is cleared of any clothing or jewellery and adhesive or metal electrodes are applied to the chest. These electrodes are connected to the defibrillator. Adhesive gel electrodes are commonly used with the automated and semi-automated units used in ambulance or non-hospital settings due to their ease of application. These adhesive gel electrodes are available in solid-gel and wet-gel forms, with solid-gel electrodes the easier to use of the two, as there is no need to clean the patient’s skin after removing the electrodes. These electrodes, however, may burn the skin, whereas wet-gel electrodes can spread the current more uniformly. The adhesive patches are also safer for healthcare personnel to use due to the very low risk of the operator coming into contact with the electrode. The operator can stand several feet away from the patient. Furthermore, the adhesive patches require no force of application, while approximately 25 lbs of force is required to apply the metal electrodes. Operating a manual defibrillator (cardioverter) requires familiarity with the equipment at hand. There are many types of manual defibrillators, each with differences, such as what the monitor face and controls look like and what type of self-adhesive defibrillation pads are used. These differences in equipment can lead to significant delays in care resulting in poor outcomes for patients experiencing cardiac arrest. If you anticipate having to operate a manual defibrillator, know what equipment will be available to you ahead of time. defibrillators usedd in hospitals, operation theaters OT rooms, Ambulance, EMS,...etc

Prepare the Equipment

As Life Point Defibrillator Dubai in UAE we do training on the use of this model

Place defibrillator on a solid, dry surface.

Turn on the manual defibrillator. Depending on the model, there might be a dial to turn or a power button to push. Defibrillators have batteries and should be fully charged. If the defibrillator monitor shows low battery output, plug the defibrillator into a power source, or obtain another manual defibrillator.

Insert the connecting cables into the receptor on the manual defibrillator.

Attach the self-adhesive defibrillation pads to the connecting cable leads.

​

Apply Paddles or Self-Adhesive Defibrillation Pads

Remove self-adhesive defibrillation pads from packaging and connect pads to conducting cables. If using paddles, connect paddles to monitor by inserting adapter into receiving port identified on the manual defibrillator.

Apply conducting gel to paddles or ensure that self-adhesive defibrillation pads are moist with sufficient conducting medium. If the pads were not properly sealed in the packaging, the conducting gel may dry out and not perform properly. In this case, get a new set of pads. for more details about how to defibrillators works: defibrillator Suppliers in Dubai. 

​

Apply paddles/pads to the chest. There are two placement options for defibrillating. With paddles, use the anterolateral placement. If using a manual defibrillator with self-adhesive pads, the anteroposterior is preferred, but if a patient cannot be moved, or it is difficult to reach the patient’s back, use anterolateral placement.

1) Anterolateral: one paddle/pad is placed to the right of the upper sternum, below the clavicle (collar bone) and one paddle/pad is placed to the left of the left nipple with the center of the paddle/pad in the midaxillary line (imagine a line extending down from the middle of the arm pit.)

2) Anteroposterior: One paddle/pad is placed over the left side of the chest, below the clavicle and the other is placed on the left side of the back below the shoulder blade and to the left of the spine

​

Defibrillate

Set the energy level for electrical discharge. There are two types of manual defibrillators: biphasic or monophasic.

​

1) Monophasic waveform device energy setting is 360 J for all defibrillation attempts.

​

unlike AED Machine (Automated External Defibrillator) for defibrillator Press the “charge” button on the manual defibrillator. If you are using paddles, there also is a charge button on the paddles.

Discharge the defibrillator by pressing the “shock” button on the manual defibrillator or, if using paddles, the discharge button on the paddles.

GENERAL INFORMATION

​

 

 

 

What is a Monophasic Defibrillator Machine?

 

Monophasic Defibrillation: A type of defibrillation waveform where a shock is delivered to the heart from one vector. In this waveform, there is no ability to adjust for patient impedance, and it is generally recommended that all monophasic defibrillators deliver 360J of energy in adult patients to insure maximum current is delivered in the face of an inability to detect patient impedance. in Life Point Defibrillator Dubai we supply this model.

​

What is Monophasic Waveform?

 

Monophasic Waveforms: A type of defibrillation waveform where a shock is delivered to the heart from one vector as shown below. It is shown graphically as current vs. time. In this waveform, there is no ability to adjust for patient impedance, and it is generally recommended that all monophasic defibrillators deliver 360J of energy in adult patients to insure maximum current is delivered in the face of an inability to detect patient impedance.

​

What is the difference between a monophasic and biphasic defibrillator?

​

Defibrillator is a device used to shock the heart back into action when it stops contracting due to a disorder of the rhythm known as ventricular fibrillation (VF). The electrodes used to deliver the shock could be either defibrillator paddles or patches, directly applied to the chest below the left collar bone and at the apex of the heart. The direct current shock given can have a monophasic or biphasic wave form. In monophasic shock, the shock is given in only one direction from one electrode to the other. In a biphasic shock, initially direction of shock is reversed by changing the polarity of the electrodes in the latter part of the shock being delivered. Usually the initial voltage applied is higher than the reversed polarity shock. Biphasic wave forms were initially developed for use in implantable cardioverter defibrillators (ICD) and later adapted to external defibrillators. Biphasic truncated exponential wave form and rectilinear biphasic waveform are two types of biphasic waveforms used by different manufacturers. Defibrillators can sense the thoracic impedance and increase or decrease their internal resistance so that the selected level of energy is delivered to the subject. Biphasic shocks are more effective than monophasic shocks and need lesser energy. Typically when 360 Joules are delivered for defibrillation in a monophasic defibrillator, 200 Joules are given in a biphasic defibrillator. This could theoretically reduce the potential damage to the heart muscle by the high voltage shock.

 

What’s Defibrillator Machine?

​

A defibrillator machine is a tool that essentially “shocks” a patient back to life. Obviously, it is more complicated than that, but it is still a fairly accurate statement. The heart is the organ in a human that transports nutrients from the head all the way down to the toes and ensures our cells continue to live and function. The heart does this by beating and acting as a pump. When the signal to tell it to beat, which is sent by pacemaker cells in the heart, gets ‘out of whack’, cardiac arrest can occur. To reset these pacemaker cells and make sure they continue to beat as they should, a defibrillator machine can be used. It is called defibrillator because it fixes a condition during hard failure called fibrillation. So as the name goes, it de-fibrillates!. Defibrillator is a device used to perform defibrillation for the purpose of turning abnormal ECG rhythm into normal rhythm. When heart enters into ventricular fibrillation, the process of returning it to its normal sinus rhythm by giving proper amount of external electric current is called defibrillation, and device used in giving such electric current is called defibrillator.  Should electrical energy is given in the form of shocks, it creates stimulation namely, myocardium is depolarized and systole occurs. To give shock to heart by means of defibrillator, heart should be in ventricular fibrillation or ventricular tachycardia rhythm without pulse. A defibrillator is an electrical device that provides a shock to the heart when there is a life-threatening arrhythmia present. The arrhythmia that we worry about is called ventricular fibrillation. This is a very rapid erratic beating of the heart. Multiple parts of pacemakers in the heart starts sort of beating erratically and the heart can’t rhythmically contract. And what the defibrillator does, it provides shock that basically shocks the heart to stop so that it can start rhythmically contracting again. Searching for AED Machine (Automatic External Defibrillator) and best defibrillator price in dubai UAE.
