Basic Life Support
What is basic life support?
Basic life support (BLS) is a lifesaving technique that involves chest compressions combined with rescue breaths (mouth-to-mouth). BLS can keep oxygenated blood flowing to the brain and other vital organs, preventing permanent brain damage (which can occur within a few minutes).
Many people do not attempt BLS because they fear that they may do more harm than good. Remember, if someone is unresponsive, there is nothing you can do to make the situation any worse – any attempt is better than none.
