1, early help
Quick response and taking measures can increase the chances of survival in a heart attack. Every minute of delay will greatly reduce the chances. Contacting the local emergency system by telephone and asking for help is the main function of on-site bystanders.
2. Cardiopulmonary resuscitation can continuously deliver oxygenated blood to the brain until other rescuers arrive. Therefore, immediate cardiopulmonary resuscitation can increase patients' chances of survival.
3. Early defibrillation
Restoring normal heart rhythm is very important for the survival of patients. On-site rescuers need to repeatedly shock the heart with defibrillators. The American Heart Association recently approved the use of defibrillators by the following personnel: emergency personnel, that is, emergency personnel in or before the hospital (such as emergency technicians (EMT), non-EMT emergency personnel, firefighters, volunteer rescuers, doctors, nurses and emergency medical assistants).
4. Early advanced cardiac life support
After defibrillation, the patient needs to be stabilized and transferred to the hospital for further treatment and nursing. Advanced cardiac life support (ACLS) includes tracheal intubation, drug therapy, monitoring and other advanced technologies for normal breathing. Many communities combine these technologies to form a fixed first aid procedure.
The purpose of extended data first aid:
1, help
Restore breathing, heartbeat, stop bleeding and treat shock. ? Prevent the injury from getting worse, treat the wound and fix the bone. ?
2. Promote recovery
Avoid unnecessary movements, handle them carefully, keep the most comfortable sitting or lying posture, and comfort them kindly.
The principle of first aid:
1, calm and bold, careful and responsible, prioritize and decisively implement the treatment method. ?
2, first deal with critically ill patients, and then deal with lighter patients; For the same patient, the life should be treated first, and then the local part should be treated.
3. Observe the site environment to ensure the safety of yourself and the injured. ?
4. Make full use of existing manpower and material resources to assist in first aid.
