The Automated external Defibrillator (AED) is a new advance device in the field of medical. Automated external Defibrillator (AED) develops in recent years to help in CPR, development came about to give shock to the patient during CPR.This helps the patient by providing counter shock to save its life. AED requires special training to run this device. It needs special skills to analyze the heart beats.
Principles of External Automated Defibrillation
This Automated external Defibrillator (AED) does many levels to cover this process. The person who uses these Automated external Defibrillator (AED)s has only to identify the heart arrest. If it happens then he pastes two probes to the patient’s chest. These probes serve a dual function. One is recording of heart beat and second is giving shock. It gives shock when it indicates.
The process of analyzing the heart beat is automatic. If the Automated external Defibrillator (AED) detects any special changes then it charges itself automatically. Some models also display the heart beat on a monitor screen.
When the Automated external Defibrillator (AED) charges itself then it warns the worker. The warning is that the Automated external Defibrillator (AED) is giving shock to the patient. There are full instructions in voice form as well as in written form on screen.
Some models show a simple method to follow in number form. The worker follows the numbers to run the AED. When the AED gives shock to the patient then it analyzes it. It analyzes the heartbeat of the patient again and again. This AED will check it three times in any one cycle.
According to current rules the Automated external Defibrillator (AED) delivers shocks in groups of three. If the third shock is unsuccessful then the machine will indicate the worker. The worker then does CPR on the patient for a minute. Then the machine will again analyze the heartbeat. It there is any problem in the patient then it charges itself again. After charging itself the machine will give further shock to the patient to analyze again.
Advantages of Automated External Defibrillators
This AED has reduced to get the training. It has increased the range of people who are able to give this process. All grades of ambulance staff can use this AED. It is not hard to use it. Everyone is able to run this AED. Now a day every emergency ambulance is having with this AED. Many other healthcare professionals are able to use this AED. It is also using in acute hospital wards and in many small clinics as well. The staff nurses can also use this Automated external Defibrillator (AED) before the heart arrest team arrives.
It is impossible to give shock to the patient with this AED. Firstly the machine will detect any problem in the patient. After that the machine will allow the worker to start the control. The worker is still responsible for giving the shock. He will ensure that everyone is clear of the patient and safe before giving shock.
Public Access Defibrillation
The conditions for doing this process are as little as 90 seconds. Delaying in doing this process will create problem for the patient. Public access has started now to reduce the delay time. This access is outside the hospital to get it easily. Anyone can use this Automated external Defibrillator (AED) before going into serious problem. For this purpose the members of the public get training to use this AED.
This scheme has given fabulous results in public places. It is using in different public places like airport, railway, and in housing areas. The public has also taken training and they help the heart arrest patient. In airport the cabin crews got training and they had helped the heart arrest patients. In one report they have survived 40% patients to leave hospital.
It is also very helpful for rural people. They avoid the ambulance service from responding quickly. They have already got training to help heart patients before getting any help from ambulances. The people who get training of this Automated external Defibrillator (AED) have this AED in their bags. They are able to reach the patient and provide initial treatment. Other methods used to decrease response times include the police and fire services with this AED.
This AED helps the people as a safety measure when they get any heart arrest. There may be chest pain in the patient. If the heart arrest occurs then this AED will check the heartbeat. After checking heartbeat then it will charge itself to give shock without any delay.
Using an Automated External Defibrillator
The first step is to completely check the safety to reach to the patient. If there are two helpers are present then they try to get help quickly. One should go to collect this Automated external Defibrillator (AED) and other to judge the patient. If the patient has arrested then give the patient basic life support. Try to switch on the screen to show the results of patient heartbeat. People who are standing try to support the patient to encourage him.
Once the AED is ready to use, the following sequence should be followed:
Switch on the machine and apply the electrode:
One probe places at the upper right border directly below the right beauty bone. The other places adjacent to the left nipple with the top margin of the pad about 7 cm below the arm pit. The correct position shows on the electrode packet. It is necessary to dry the chest. It may be wet due to sweat. It is also necessary to shave the hair from the chest. A sharp razor can use for this purpose.
Follow the voice prompts and visual directions:
The readings of heartbeats are usually automatic. In some machines it shows by pressing the “analyze” button.
Administer shock if indicated:
Ensure that no one is in contact with the patient and shout “stand clear.” If the light illuminates then press the shock button once. The machine indicates it is ready to deliver the shock.
Repeat as directed for up to three shocks:
Do not check for a pulse or other sings of heartbeat between the three shocks. It will disturb the machines to analyze the heartbeat reading. Some machines have motion sensors in it. They can detect the disturbance from the worker and will advise no contact between shocks.
Give cardiopulmonary resuscitation as required:
If there is no pulse or other sign of a heartbeat after three shocks then give CPR for one minute. One minute is machine time. After one minute it warns the worker to reanalyze the heartbeat. This procedure may start automatically. It depends on the machines settings. The machine will give shocks as per settings.
If circulation returns, check for breathing:
If there is need of rescue breathing then give to patient to stable him. Check the patient after every minute to ensure that signs of heartbeats are still present. If the patient shows signs of recovery then place in the recovery position.
Liaise with emergency services:
Give all the details to the emergency services.
Report the incident
Report the medical supervisor. He will get the report from the machine. Ensure all supplies demolish from the machine for the next use.
