The purpose of Wikipedia is to basic life support american heart association pdf facts, not to train. Healthy people maintain the CABs by themselves. BLS helps the patient ensure his or her own CABs, or assists in maintaining for the patient who is unable to do so. Bystanders with training in BLS can perform the first three of the four steps.
Airway and look into the mouth for obvious obstruction. Also to apply a ‘head tilt chin lift’ or ‘jaw thrust’ to open the airway. Breathing for 10 seconds by listening for breath at the patients nose and mouth and observe the chest for regular rising and falling breathing movements. If the patient is unresponsive and not breathing, the responder begins CPR with chest compressions at a rate of 120 beats per minute in cycles of 30 chest compressions to 2 breaths.
If responders are unwilling or unable to perform rescue breathing, they are to perform compression-only CPR, because any attempt at resuscitation is better than no attempt. For children, for whom the main cause of cardiac arrest is from breathing related issues, 5 initial rescue breaths is highly advised followed by the same 30-2 cycles. According to the American Heart Association, in order to be certified in BLS, a student must take an online or in-person course. However, an online BLS course must be followed with an in-person skills session in order to obtain a certification issued by The American Heart Association. C-A-B is recommended in the new AHA EU guidelines so as to ensure the blood supply to the vital organsand to prevent degeneration of the brain cells . Keeping these facts as such follow the sequence introduced by AHA guidelines 2010 recommendations C-A-B should be followed in learning and teaching BLS.
Ensure that the scene is safe. If no response call for help by shouting for an ambulance and ask for an AED. Transport if required, or wait for the EMS to arrive and take over. 30 chest compressions in 18 seconds followed by two rescue breaths in 4 seconds each lasting for 2 second.
Blind finger-sweeps should never be performed, as they may push foreign objects deeper into the airway. This procedure has been discarded as this may push the foreign body down the airway and increase chances of an obstruction. Continue chest compression at a rate of 100 compressions per minute for all age groups, allowing chest to recoil in between. For adults push up to 2-2. 4inches,ie,6 cm and for child up to 2 inches,ie,5 cm. 3 of the chest diameter antero-posteriorly. Allow recoil of chest fully between each compression.
In adults,irrespective of the number or rescuers, for every 30 chest compressions give two rescue breaths and in child victim, give 2 breaths per 30 compression if only 1 rescuer is present,but 2 breaths per 15 compressions in case where there are 2 rescuers. Continue for five cycles or two minutes before re-assessing pulse. The mouth-to-mouth technique is no longer recommended, unless a face shield is present. If ventilation is still unsuccessful, and the victim is unconscious, it is possible that they have a foreign body in their airway. Begin chest compressions, stopping every 30 compressions, re-checking the airway for obstructions, removing any found, and re-attempting ventilation.
After 5 cycles of CPR, the BLS protocol should be repeated from the beginning, assessing the patient’s airway, checking for spontaneous breathing, and checking for a spontaneous pulse as per new protocol sequence C-A-B. If defibrillation is performed, begin chest compression immediately after shock. At the end of five cycles of CPR, always perform assessment via the AED for a shockable rhythm, and if indicated, defibrillate, and repeat assessment before doing another five cycles. Rescuers should provide CPR as soon as an unresponsive victim is removed from the water. In particular, rescue breathing is important in this situation.
