What’s a manual defibrillator?

[ad_1]

A manual defibrillator is a medical device used to treat heart problems. Depending on the patient’s condition and medical recommendations, the medical expert delivered voltage shocks to the heart by placing electrodes on the patient’s chest. It is used for various cases of heart conditions such as cardiac, ventricular fibrillation and ventricular tachycardia. Basically, manual defibrillators are the devices used to restore proper functioning of the heart in critical or emergency situations. They are found in various different places and are not limited to hospitals and medical clinics.

The different types of defibrillators include manual defibrillator, automated external defibrillator and implantable. They are generally used for the same purpose, which is to supply electricity to the heart to restore normal heart condition. A manual defibrillator, an external type, uses electrocardiogram readings to show the amount of voltage required to apply. They are very efficient and need expert supervision to ensure proper operation. The next level of defibrillator is the automated external defibrillator. It is the most advanced type of defibrillator because it automatically measures and decides the magnitude of the voltage shock to the heart. Internal, or implantable, defibrillators are used for internal monitoring of the heart using the pulse generation technique.

The first step towards manual defibrillator application is preparation. The defibrillator must be ready and safe for further use. It should be placed on a hard dry surface, the charge supply controlled and the cables and electrodes connected. The voltage requirement should be checked, depending on the type of manual defibrillator, as there are two types of defibrillators; single-phase and two-phase. The charge button will be pushed to the on position, which can be found on the equipment or pads. Once ready, the shock button is pressed when rescuers are ready to deliver the life-saving shock.

There are few guidelines for using a manual defibrillator in an emergency. An experienced physician should be consulted if the user is not adequately trained in its use, as the application of an Automated External Defibrillator (AED) requires expert help. The placement area should be cleared and the electrodes should be placed on the chest so they can be used to help restore heart rate. The patient’s condition is checked by plugging the AED in, whether the patient needs a turn on tension or not. If the AED requires an electric shock to be delivered, the electric shock must be provided. The patient and manual defibrillator should be monitored until the machine indicates that the device is no longer needed.
