Basic Life Support (BLS) course

In many cases, cardiac arrest is preceded by respiratory arrest. Therefore, it is important to be able to recognize respiratory issues in order to take steps to prevent cardiac arrest.

When a person of any age has a pulse but is not breathing (or is not breathing well), immediately open the airway using the head-tilt/chin-lift maneuver and begin rescue breathing. See Table2 for details on rescue breathing.

Age Group How Often Breaths per Minute Duration Evaluation
Adult Every 6 seconds 10 to 12 breaths per minute Each breath should last one second Check for chest rise and breathing;

Child/Infant One rescuer: Every 6 seconds
Two rescuers: Every 2 to 3 seconds
One rescuer: 10 to 12 breaths per minute
Two rescuers: 20 to 30 breaths per minute
