The operator may give you first aid instructions over the phone. If you can, put your phone on loudspeaker. A person in cardiac arrest may grunt, snort or take gasping breaths — this is not normal breathing. Although CPR steps are the same for adults and older children, the technique for babies and young children years is slightly different.
Note: You may need to use the palm of your hand instead of your fingers depending on the size of your baby. CPR can be tiring. If you need a break, ask someone else to assist with minimal disruption. Rotate the person performing compressions every 2 minutes. If you find mouth-to-mouth difficult, continue with chest compressions until medical help arrives.
Sometimes, people will have their ribs broken by chest compressions. This is still better than the alternative of not receiving CPR. If this occurs, pause and reposition your hands before continuing or get someone else to take over. It can analyse abnormal heart rhythms and send an electric shock or pulse to get the heart to return to its normal pumping rhythm.
The pads must be attached to the skin and the machine turned on. There are different types of AEDs and some are available in public places such as shopping centres and schools. It is important to follow the prompts on the AED. Do not touch the person during analysis or shock delivery. If there is an emergency, knowing simple first aid can mean the difference between life and death. Consider taking a first aid course. First aid training courses are available across Australia.
A course typically takes a couple of hours and can be taken online or in person. Times are also flexible. Participants learn basic first aid skills including CPR and usually receive a certificate. Follow up refresher courses are recommended every 3 years.
Repeat these compressions at a rate of to times a minute until an ambulance arrives or you become exhausted. CPR with rescue breaths Place the heel of your hand on the centre of the person's chest, then place the other hand on top and press down by 5 to 6cm 2 to 2.
After every 30 chest compressions, give 2 rescue breaths. Tilt the casualty's head gently and lift the chin up with 2 fingers. Pinch the person's nose. Seal your mouth over their mouth, and blow steadily and firmly into their mouth for about 1 second.
Check that their chest rises. Give 2 rescue breaths. One common cause, especially in adults, is an abnormal heart rhythm Overview of Abnormal Heart Rhythms Abnormal heart rhythms arrhythmias are sequences of heartbeats that are irregular, too fast, too slow, or conducted via an abnormal electrical pathway through the heart.
Heart disorders are Another possible cause is stopping breathing, such as when a person drowns or has a severe lung infection or severe asthma attack. A person in cardiac arrest lies motionless and does not respond to questions or to stimulation, such as shaking. The person may not be breathing or may have gasping, irregular breaths called agonal breathing. The crucial steps that should be done to maximize a person's chance of survival are called the cardiac arrest chain of survival Out-of-Hospital Chain of Survival Cardiac arrest is when the heart stops pumping blood and oxygen to the brain and other organs and tissues.
Sometimes a person can be revived after cardiac arrest, particularly if treatment is The survival chain begins with bystander recognition of cardiac arrest and continues through calling for emergency services, providing cardiopulmonary resuscitation CPR and defibrillation when available, and giving high-quality post-arrest care in a hospital.
Without successful accomplishment of each of these steps, it is unlikely that a person will survive. Recognition and treatment of cardiac arrest should ideally occur at virtually the same time. A rescuer who finds someone unconscious should first determine if the person is unresponsive by shaking the person and loudly asking, "Are you okay? If the person does not respond to stimulation and is not breathing or is breathing abnormally for example, gasping , emergency resuscitation with CPR is begun and the local emergency medical service is called in the US, calling Rescuers should not try to check for a pulse but should start CPR as soon as possible because the risk of doing chest compressions on a person not in cardiac arrest is much lower than the risk of not doing chest compressions when needed.
CPR should be started immediately by one rescuer, while a second rescuer contacts emergency services and retrieves an automated external defibrillator AED if available. Some emergency services dispatchers provide telephone instructions to help direct care, including giving instruction in how to do compression-only CPR Compression-only CPR Cardiac arrest is when the heart stops pumping blood and oxygen to the brain and other organs and tissues.
An AED can rapidly determine whether the person has an abnormal heart rhythm that can be treated by an electric shock called defibrillation. If the AED detects an abnormal rhythm that could be corrected, it delivers a shock, which may start the heart beating again.
AEDs are easy to use and are available in many public gathering places. Written instructions for use are available on each AED and should be followed. Early access to emergency care: The earlier a bystander recognizes that cardiac arrest has occurred, the sooner someone can call emergency medical services, and the sooner personnel will arrive on site to deliver advanced care.
Early cardiopulmonary resuscitation CPR : The sooner the rescuer starts CPR particularly chest compressions , the greater the chance the brain and other vital organs will receive enough oxygen to keep the person alive until an automatic external defibrillator AED can be used or more advanced medical care provided. Early defibrillation: Sometimes an electrical shock, called defibrillation, needs to be given to restore the heart's normal rhythm.
The sooner this is done, the better. Early provision of advanced medical care: The sooner emergency medical services EMS personnel can take over what the rescuer started, the sooner the person can benefit from advanced medical care. People who are resuscitated need advanced monitoring and treatment and eventually rehabilitation and other measures to improve recovery.
An automated external defibrillator AED is a device that can detect and correct a type of abnormal heart rhythm called ventricular fibrillation. Ventricular fibrillation causes cardiac arrest. AEDs are easy to use. Most training sessions take only a few hours; but it is possible to use an AED even if you have never participated in a training course.
Different AEDs have somewhat different instructions for use. AEDs are available in many public gathering places, such as stadiums, airports, and concert halls. People who are told by their doctor that they are likely to develop ventricular fibrillation but who do not have an implanted defibrillator may want to purchase an AED for home use by family members, who should be trained in its use. In addition, taking periodic refresher courses can help because procedures may change over time.
Studies have shown that compressions-only CPR is as effective as standard CPR for adolescents and adults in the first few minutes of cardiac arrest. Standard CPR may be more effective for children and infants, and for people whose cardiac arrest is due to respiratory causes, but only if the rescuer has been trained. On television and in the movies, people who collapse due to cardiac arrest and receive cardiopulmonary resuscitation CPR often awaken during, or after, CPR is done. In real life, it is much less likely that people will be revived by CPR itself.
Instead, CPR is done to circulate oxygen-containing blood from the lungs to the brain and organs until the heart can be restarted with a defibrillator, often with the help of special drugs given by emergency medical services personnel.
