When a victim can not properly breath, you will notice them having high pitched noise during inhaling, they have poor air exchange and the can not be able to talk.
When an adult victim requires BLS, you first access them; if not breathing or properly breathing perform CPR. Check for pulse for approximately 5-10 seconds. If there is no pulse still, perform at least a hundred compression per minute. Open the airway and give 2 breaths. Continue with the cycle until helps an ambulance arrives.
When offering CPR to an adult, the compression ratio is 30 compressions to 2 breaths.
A victim should never be moved expect when the surround is dangerous or the victim is in a position making it difficult for you to you perform CPR.
Mouth to mouth breathing is fast and more effective way of providing breaths to a victim. The rescuers exhale has 17 percent oxygen and 4 percent carbon dioxide which is enough to meet a victim’s need.
The 2010 AHA guidelines for CPR recommend a BLS sequence from airway- breathing-compression to compression- airway- breathing.
Prevention of cardiac arrest, early CPR, rapid defibrillation, advanced airway support and integrated post cardiac arrest care
Power on your AED and listen carefully to the spoken direction of the AED, attach pads to the victim’s chest, if the AED will advise a shock clear the victim and press shock button.
Find carotid pulse on the neck side that is close to you; take five second to ten seconds to check for the pulse. If there is no pulse perform CPR and check again for the pulse.
There are two methods a rescuer can us to open an airway; head tilt chin lift method and jaw thrust method.
BLS training questions will give you a guideline of some of the questions asked during a BLS test.
