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

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) Biphasic waveform devices have device-specific energy levels that are indicated on the defibrillator. If you do not know the device specifics, the default initial energy setting is 200 joules (J).

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

​

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’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 best price cost defibrillator Suppliers in Dubai, send us your inquiry and let the experts talk to you

What’s Defibrillation?

​

Defibrillation is a procedure used to treat life threatening conditions that affect the rhythm of the heart such as cardiac arrhythmia, ventricular fibrillation and pulseless ventricular tachycardia.

The procedure involves the delivery of an electric shock to the heart which causes depolarisation of the heart muscles and re-establishes normal conduction of the heart’s electrical impulse. The machine used to deliver this therapeutic shock to the heart is called a defibrillator.

​

Understanding Defibrillation Waveforms

​

Before we start, let’s define a few terms:

1) Energy: Energy in a defibrillator is expressed in joules. A joule is the unit of work associated with one amp of current passed through one ohm of resistance for one second.When we express it in a formula, it is generally stated as follows:
Joules (Energy) = Voltage  X  Current  X  Time

Joules have become a surrogate for current in modern defibrillator language.

​

2) Current: Current is what actually defibrillates the heart. It is also expressed as Voltage/Impedance (resistance).

​

3) Impedance: Resistance to Flow; there is resistance in the electrical circuit itself as well as in the patient. The amount of impedance in a patient is difficult to determine as it relates to body mass, temperature, diaphoresis quality of the contact with paddles or pads. Impedance is expressed in ohms.
