Until an advanced airway is inserted, the rescue team should use mouth-to-mouth, mouth-to-mask, or bag-mask ventilation. An advanced airway (supraglottic airway, laryngeal mask airway, or endotracheal tube) provides a more stable way of providing breaths and should, therefore, be inserted as early as possible in a resuscitation effort. Once an advanced airway is in place, the compression to breath ratio should be adjusted as noted below.
The compression rate for all persons is always 100-120 per minute.
|Compression to Breath Ratio||No Advanced Airway||Advanced Airway|
|Adult||30 compressions followed by two breaths||One breath every 6 |
seconds without pauses in compressions
|Child/Infant||30 compressions followed by two breaths for one rescuer |
15 compressions followed by two breaths for two rescuer
|One breath every 6 seconds without pauses in compressions |
One breath every 2-3 seconds (20-30 breaths per minute)
