fully accredited online courses CPR/BLS and ACLS - from safety organizations such as The American Heart Association®

Basic life support (BLS) is a stage of medical care which is used for patients with life-threatening illness or injury until the patient can be given full medical care. It can be provided by trained medical personnel, including emergency medical technicians, and by laypersons who have received BLS training. BLS is generally used in the pre-hospital setting, and can be provided without medical equipment.

The term BLS refers to maintaining an airway and supporting breathing and the circulation. It includes the following elements:

Initial assessments

Airway maintenance

Expired air ventilation (rescue breathing, mouth to mouth ventilation)

Chest compression

When all are combined, the term CPR (cardiopulmonary resuscitation) is used. BLS refers that no equipment is used, when a simple airway or face mask for mouth to mask recitation is used, this is defined as Basic Life support with airway adjunct. The purpose of BLS is to maintain adequate ventilation and circulation until a means can be obtained to reverse the underlying cause of the arrest. It is therefore a holding operation, although on occasion, particularly when the primary pathology is respiratory failure, it may itself reverse the cause and allows full recovery.

Basic life support or BLS is essential medical aid which is offered to people before they reach a hospital or in circumstances where high-level medical care is not instantly available. Emergency medical technicians, paramedics, and other first responders can perform BLS, and people without formal medical training may be able to offer basic life support after taking a workshop to learn the basics.

The key to BLS is upholding the ABCs: airway, breathing, and circulation. When providing BLS, responders can make use of cardiopulmonary resuscitation (CPR) to resume the patient's breathing, if needed, and they can also give vital treatment for cuts, broken limbs, and other problems. Often, the aim is just to make the patient stable. Drugs are generally not part BLS.

In BLS guidance, people gain knowledge about code of actions should be follow, which begins with securing the scene and then influential whether or not the patient is receptive. If the patient is insensitive, a series of steps can be taken to make the patient's condition more stable.


Saving lives of people is a noble thing to do and not every person can do that. One may learn how to give CPR through enrolling in a prestigious training school that should be recognized worldwide.
